Rumag Series 0
Types: REG, REVG and REG-S-VG-0
Largest of the Series 0 models, the horizontal REG, vertical REVG and combined horizontal and vertical ram-head REG-S-VG-0 were easy-to-operate, neatly designed machines with particularly clean lines. Each was available with a choice of two tables - the smaller 700 x 200 mm and the larger 800 x 220 mm with longitudinal travels of 400 and 500 mm respectively. Cross and vertical travels were identical across the range, the former at 150mm the latter at 325 mm or, optionally, 425 mm. The table power-feed motor was usually a 3-speed type (though single and two-speed versions were also available) that gave a very wide range of feeds: 16 to 500 mm per minute together with and rapids, these being at the same rate on all axes at 2000 mm/min.
As on the smaller models, a number of table-feed options were available: "S", "SE", "SKE" and "SEP". On the basic "S" System 9 automatic feeds disengaged by mechanical trip stops, the "SE" adding a high-speed return function with control by electrical push buttons. Intended for simple, repetitive production work, the 9-speed "SKE" had a lever-operated table quick-return, with an automatic re-engagement of the feed when the lever activated a trip cam at the end of its travel. Similar in function to the "SE", the "SEP" was equipped with program control of the table's movement - though this was of the very simple kind that gave a rapid approach followed by a slow feed for the cut and a return at high speed.
If automatic cycle feeds were required, Rumag offered the "435" conversion, a system could be fitted to both the horizontal and vertical model. A stepless DC drive was employed and could be diverted to each of the three axes by an electrically controlled clutch operated by push-button control.
Fitted with a 30 INT taper (or, optionally, a No. 3 Morse) both horizontal and vertical spindles were driven by the usual wide choice of motors: a 700 r.p.m. version gave six speeds from 71 to 710 r.p.m.; a 1400 r.p.m. unit (the most commonly fitted) produced 140 to 1400 r.p.m. while the 2800 r.p.m. example gave 280 to 2800 r.p.m. Two versions of a 2-speed motor were also listed: one, running at 450/1400 r.pm. produced spindle speeds of 45 to 1400 r.p.m. and the other, running at 450 and 2800 r.p.m. motor, gave a range from 45 to 2800 r.p.m. Motors were mounted within the main column and drove the spindle directly by 3 V-belts on higher speeds and through a simple reduction gearbox (resembling a lathe backgear) on the lower. The ram head on the REG-S-VG was given the designation VG and had 9 speeds of 80,160, 250, 320,500, 700, 1000, 1400 and 2800 r.p.m. - all driven by a motor flange mounted the rear. Like other Rumag ram models the quill was fixed, though the end could be rotated through 360°.
On the vertical-only model, the REVG-S, the head was clamped to the face of the main column by four bolts (it could be rotated through 90° in each direction from vertical) and took its drive from a horizontal spindle - fine-lapped, spiral-toothed Klingeinberg-Palloid bevel gears turning the drive through 90°. With 75 mm of travel, the quill could be operated by either a capstan handwheel for a quick drilling feed, or by a full-circle handwheel and worm-and-wheel gearing for fine feeds..

Rumag Series 0
Types RF-1 and RE-1
Rather larger and of more general use were the next models in the range, the Types RF-1 and RE-1 - both identical, save for the table fitted, that on the RF being 450 x 150 mm and on the RE 650 x 180 mm. Popular machines (by the mid 1970s over 6000 had been sold) they were intended for general machine-shop and production work and also proved highly suitable for installation in technical training institutes. Drive came from a motor held within the stand via an intermediate countershaft supported in an eccentric housing that allowed an easy slackening of the V-belt's tension when a speed change was required. Again, as with most Rumag models, a number of different drive options were offered, from a simple 6-speed type to an 18-speed version with a 3-speed motor.
Table feed on ordinary models was by hand only, with 170 mm of travel longitudinally when fitted with the 450 mm table and 320 mm with the 650 mm version. Cross travel on the RF was120 mm, but, due to the table's increased width, reduced to 90 mm on the RE (the knee casting remaining unchanged). Vertical travel was the same for both models at 170 mm. As with the RF-0 types an endless number of combinations of lever, screw or combined lever and screw could be fitted to the three axes, so allowing the utmost flexibility in setting a machine up for a particular task. Also available was the option of an auto-cycle mechanism using a pneumatic-hydraulic drive, these versions being listed as the Models RF-1-PH and RF-1-RE and able to perform a rapid approach, a feed cut and then a rapid return.
Configuration and designation of table feeds on all Series 0 Models were listed as follows:
A= lever horizontal feed
B= screw horizontal feed
C= screw and lever horizontal feed
D = screw cross feed
E= lever cross feed
F= screw and lever cross feed
G= lever vertical feed
H= screw vertical feed
I = screw and lever vertical feed
Rumag Series 0: Models RF-415 and RFV-415
Altogether heavier and more massively constructed, the RF-415 (horizontal) and RFV-415 (vertical) Series of Rumag millers could be configured in a number of interesting ways. However, a basic machine underpinned them all, with the main motor held within the cabinet stand driving to an intermediate countershaft by three V-belts - with a single final belt to the spindle running over a 4-step V-pulley. Electrical switchgear was contained within a cabinet booted to the machine's right-hand side, a thoughtful touch being to cover the top with a sheet of ribbed rubber matting to allows tools and cutters, etc., to be placed out of harm's way.
Hardened and ground, the spindle ran in specially selected, high-accuracy double-row roller bearings of the NN type, the assembly being adjustable to remove play. With a 2-speed motor the eight spindle speeds ran from 71 r.p.m. through 140, 200, 280, 400, 560, 800, 1120 to 2240 r.p.m. With a 3-speed motor some 24 speeds were available that spanned a very useful 100 to 4500 r.p.m. - though, as the drive was direct on all speeds and not though any form of reduction gearing to help eliminate belt slip (as on many Tom Senior machines for example), the torque available at low speeds must have been insufficient to make any real use of wide slab cutters.
Three tables were available: 450 x 150 mm with just a single, central T slots and travels of 250 mm longitudinally, 140 mm across and 350 mm vertically, Next was a 650 x 180 mm with three T-slots on 50 mm spacing and travels of 320 mm longitudinally, 110 mm across and 350 mm vertically. Largest of all was a 700 x 200 mm unit, again with three T slots (but this time on 45 mm spacing) and with travels of 400, 110 and 325 mm for longitudinal, across and vertical respectively. As on the Company's smaller machines each table-feed axis could be driven by a handwheel, a quick-action lever or even, at extra cost, fitted with both systems. Although the two smaller tables were limited to feed by hand only, the largest could be fitted with power feed, with four different types of operation: "S", "SE", "SKE" and "SEP". On the "S" the drive came from a 3-speed (700, 950 and 1400 r.p.m.) motor flange mounted against the rear of a gearbox itself fastened to the right-hand face of the miller's main column. Connection from gearbox to knee was by the usual type of universally jointed and splined shaft, the system producing (on all versions) nine feed rates of 16, 22, 32, 63, 90, 125, 250, 350 and 500 mm per minute. On the basic system (as used on the "S"), disengagement was by mechanical trip stops, the "SE" adding a high-speed return function with control by electrical push buttons. Intended for simple, repetitive production work, the "SKE" had a lever-operated table quick-return, with an automatic re-engagement of the feed when the lever activated a trip cam at the end of its travel. Similar in function to the "SE", the "SEP" was equipped with program control of the table's movement - though this was of the very simple kind that gave a rapid approach followed by a slow feed for the cut and a return at high speed.
Limited in its usefulness by the absence of a quill feed on the head, the standard vertical miller was given the model designation RFV-415 (though as an alternative the customer could choose instead the horizontal model and specify the fitting of a Type VK self-motorised, high-speed vertical head. This had a lever-action, 75 mm travel quill and 6 speeds of 1000, 1600, 2000, 2500, 3150 and 5000 r.p.m. - or optionally, 125, 250, 500, 1000, 2000 and 4000 r.p.m. - and was thus able to tackle a wide range of jobs from fly-cutting to the use of small milling cutters and co-ordinate drilling. Another option was the VG-O self-contained ram head, a unit introduced in the mid 1970s, that had a motor flange mounted against its rear face connected to an enclosed, oil-bath gearbox - the whole unit also serving as a replacement overarm for horizontal work. Unfortunately, although the head could be swivelled through 90° each side of vertical, and had nine speeds of 80, 160, 250, 320, 500, 700, 1000, 1400 and 2800 r.p.m., the quill on this, the smallest version of the VK type, was fixed..

Rumag Series 1
Types: REE-1, RU-1, REEV-1, RU-1-VG and REE-1-VG
Built in five versions - the horizontal REE-1, universal RU-1, vertical REEV-1, ram-head vertical/horizontal REE-VG and ram-head horizontal-vertical-universal RU-1-VG - Rumag Series 1 millers were, in reality, just one basic type suitably modified in specification for a particular application. This approach allowed the fitting of many common parts and hence economy of production and wide interchangeably of accessories.
Both horizontal and vertical spindles could be ordered with ISA 30 or 40 fittings or even a No. 3 or No. 4 Morse. Two drive options were offered, "A" and "B", The "A" system used a 3 (optionally 4) kW motor driving a 6-speed column-mounted gearbox that in turn connected to a high-low range box. The final drive gear of the second box was on the spindle itself (and of large diameter and weight to provide a flywheel effect) and positioned immediately behind the front double-row, high precision cylindrical roller bearing. Fitted with a 1400 r.p.m. motor speeds spanned 36 to 1400 r.p.m. and with the optional 2800 r.p.m. unit from 71 to 2800 r.p.m. Electrical switchgear and controls - for spindle and table drives - were neatly contained in a separate box to the right-hand side of the knee.
Less expensive, the "B" drive employed a 2-speed 1400/2800 r.p.m. motor with a 3-step V-pulley on its spindle driving to the same high-low range box used on the "A" drive. Thus equipped this machine had 24 speeds from 36 to 2800 r.p.m. As ever, Rumag were happy to oblige their customers and could also supply, at extra cost, the "A" drive with a 2-speed motor to give the same twenty-four speeds.
On the vertical miller the same drive system was used but with the drive to the swivelling head (clamped in place with four bolts) turned through 90° by fine-lapped, spiral-toothed Klingeinberg-Palloid bevel gears. On both types twelve speeds were provided ranging from 25 to 1000 r.p.m. with a 1400 r.p.m. motor and twice as fast with the 2800 r.p.m. option. The independently powered ram-head was fitted with a 3-speed 700/1400/2800 r.pm. motor and had nine speeds from 80 to 2800 r.p.m. All gears and shafts in the drive systems were manufactured from high-quality materials, hardened and ground and ran in precision roller races. Simple but reliable oil bath lubrication was provided with inspection windows to check the level.
As an accessory for the horizontal models the Type VK self-motorised, high-speed vertical head was offered. This had a lever-action, 75 mm travel quill and six speeds of 1000, 1600, 2000, 2500, 3150 and 5000 r.p.m. (or optionally, 125, 250, 500, 1000, 2000 and 4000 r.p.m.), and was thus able to tackle a wide range of jobs from fly-cutting to the use of small milling cutters and co-ordinate drilling.
Each model was available with a choice of three 250 mm wide tables - 800, 1000 or 1250 mm (all with three 16 mm wide T slots on 50 mm spacing) with longitudinal travels of, respectively, 500, 700 and 800 mm by hand or under power. However, if the handles were removed each travel was increased by 100 mm. Cross travel, at 205 mm, was the same on all models, as was vertical (at 500 mm) on all but the REEV-1 vertical (where it was reduced to 460 mm). Power feeds in all directions were driven by a variable-speed, externally mounted DC motor that gave rates from 20 to 2000 mm/min - the fastest of which also doubled as a "rapid". For safety, the table and knee handwheels were arranged to disengage automatically when power feeds were engaged. Control of feed rate was by a dial with selection of direction by push-buttons and stop by either hand or adjustable trip dogs.
As an option, a simple form of programme control was offered; similar to that fitted to the smaller Rumag machines this gave a rapid forward motion, the appropriate feed rate and a rapid return. Start could be from the left or the right - and it was possible to include in the system a number of automatic, power-driven rotary tables and dividing heads..

Type VK self-motorised, high-speed vertical head with a lever-action, 75 mm travel quill and six speeds of 1000, 1600, 2000, 2500, 3150 and 5000 r.p.m. or, optionally, 125, 250, 500, 1000, 2000 and 4000 r.p.m.

Rumag Series 2
Types: Horizontal RE-2-G, , RE-20-G and RE-25-G; Universal Models RU-2-G, RU-20-G and RU-25-G; Vertical Models REV-2, REV-20 and REV-25 and the Vertical-Combination "Rumaversal" RE-2-VS, RU-2-VS, RE-20-VS, RU-20-VS, RE-25-VS and RU-25-VS
Using the same base, column, knee, table, cross support, overarm and other larger components, the Series 2 miller was built in a wider variety of styles and with a greater choice of specification than the others in the maker's range. The main version offered were plain horizontal, universal with swing table, vertical and as a horizontal fitted with an internal gearbox ram-type vertical head with a double-swivel end that had 100 mm of fine-feed quill travel.
Driven by a motor contained within the main column, the horizontal models (Types RU and RE) had a stiffly supported main spindle, made from hardened and ground steel, running in selected, high-precision double-row bearings and driven by multiple V-belts on the higher speeds and through gears on the lower. The pure vertical models (REV) used the same spindle drive but with the motion turned through 90° by fine-lapped, spiral-toothed Klingeinberg-Palloid bevel gears. Clamped to the column face by four bolts, the head could be rotated through 360° and had a quill with 100 mm of travel operated by a full-circle handwheel that gave a fine feed. Motor power varied according to machine type with the smallest models, the RE-2-G and RU-2-G and Rumavertical RE-2-VS and RU-2-VS, having as standard 4 or 5.5 kW; all other types were also offered with a choice - 5.5 or 7.5 kW  - although the vertical machines, the REV-2, REV-20 and REV-25, were usually supplied with the more powerful option. Motors were available as single or 2-speed types of which two of the former and one of the latter were listed: for all the ordinary horizontal and vertical types with a 1400 r.p.m. 1-speed unit the twelve spindle speeds ranged from 25 to 1050 r.p.m.; the 2800 r.p.m. version gave 100 to 2100 r.p.m. and with the 2-speed 1400/2800 r.p.m. type a very useful twenty-four speeds from 25 to 2100 r.p.m. The geared ram head on the Rumavertical was offered with various motors: a 1400 r.p.m. of 4 or 5.5 kW on the RE-2-VS gave ten speeds from 56 to 2800 r.pm. and a 2-speed 1400/2800 version twenty speeds from 28 to 2800 r.p.m.  The two larger versions could be fitted with either a 5.5 or 7.5 kW single-speed 1400 r.p.m. type or a 2-speed 1400/2800 r.p.m. version - the resulting spindle speeds being identical to the smaller model. All splines, gears and shafts (the latter supported in either ball roller bearings) were made from hardened and ground steel of the highest quality with lubrication by oil bath.
Each size of miller was offered with a choice of tables: the RE-2 in horizontal, universal and Rumaversal forms could be had with either a 1000 x 330 mm and all other versions with a choice of 1250 x 330 mm, 1450 x 330 mm, 1300 x 400 mm and 1500 x 400 mm.
Travels varied from 700 mm longitudinally on the 1000 mm table to 900 mm on the 1250 mm version and 1100 mm on the 1450 and 1500 mm lengths. While the RE-2-G and RE-2-VS were limited to 280 mm of cross movement the RE-20-G, RE-20-VS and RE-25-VS had 350 mm. Vertical movements were 480 mm on all the vertical REV types, 500 mm on the RE-2-G and RU-2-G and 530 mm on the larger RE-20-VS and RU-20-VS models.
While the smaller types had conventional speed-change table-feed gearboxes (that gave a range of twelve rates from 15 to 750 mm/min. horizontally and across directions and from 7.5 to 375 mm/min. vertically) feeds on all the Type 25 versions were driven by a variable-speed, externally mounted DC motor that gave longitudinal and cross rates from 20 to 2000 mm/min and vertical set more sensibly at 10 to 1000 mm/min. Rapids on all types were at 2000 mm/min laterally and 1000 mm vertically. Control of feed rate was by a dial, with selection of direction by push-buttons and disengagement by either hand or adjustable trip dogs. As a safety measure the table and knee handwheels were arranged to disengage automatically when power feeds were running.
By the early 1970s Rumag were offering the Series 2, in all its forms, with NC control, their preference being for installations by Heidenhain. 
Rumag Milling Machine Designations for the Series 2:
R = Rumag milling machine
2 = Series 2 machines
20 = Series 2 Heavy model
25 = Series 2 Heavy model with stepless table feeds
E = Plain horizontal miller without swivel table
U = Universal miller with a table able to be swung 45° in each direction from central
EV = vertical miller without swing table
G = Horizontal miller with standard overarm
VS-1 = Horizontal miller with ram-type overarm incorporating a motorised vertical head swivelling 365° in two planes
VS-2 = Horizontal milling machine (as VS-1) with vertical head having 100 mm of quill stroke
VS-3 = Horizontal miller similar to the VS-2 with a head swivelling 360° in one plane only
A = Power in-and-out feed of the ram head by a separate motor
For example the RU-20-VS- 2-A would have been a Series 2 horizontal "Heavy" model fitted with a ram-type vertical milling attachment able to swivelled in two directions from central and with power in-and-out feed..

Rumag Series 3
Types: RE-30, RU-30, RV-30, RE-30-VS and RU-30-VS
Largest of the Rumag machines, the Series 3 was, like the Series 1 and 2, based on a single model adapted to a variety of specifications as the Plain Horizontal RE-30, the Universal swing table (45° in each direction from central) RU-30, Vertical RV-30 and the Rumaversal, a combined Horizontal/Vertical/Ram Head sold as the RE-30-VS with a fixed table and the similar RU-30-VS with a swivel table.
Of massive construction and considerable weight - around 4000 kg - the miller had modern, clean lines and could be adapted, in all its forms, to CNC control, the maker's preference being for installations by Heidenhain. The main castings were all heavily built and internally ribbed, the base plate having especially strong ones in a W-section. Slideways were especially wide - 420 mm on the vertical knee ways and 430 mm on the cross - and the table longitudinal ways fitted as standard with forced lubrication (a fitting that could be provided at extra cost to the other slides). Adjustable double bronze nuts were fitted to the cross feed and an anti-backlash device to the longitudinal, the latter device intended to allow cuts to be made in the same direction as the rotating cutter (climb milling) when using an auto cycle feed or under CNC control. 
Like contemporary Parkson machines, Rumag specified a (3 kW) DC variable-speed drive to the table feeds and omitted handwheels at the table ends, these being provided, together with electrical switches to select feed direction, at the front of the machine. Feeds were engaged through push-button controlled electromagnetic clutches - a wonderful system until they fail and it's discovered that the maker has gone out of business. Feed rates could be varied between 10 to 1000 mm/min on all models with rapids set at the single rate of 2000 mm longitudinally and across and at 1000 mm/min vertically. Although tables were available in just one width - 450 mm - three choices of length were available: 1250, 1600 and 1800 mm. Each had four 16 mm T-slots on 75 mm spacing and travels of, respectively: 900, 1250 and 1450 mm. Cross travel was 400 mm on every models and vertical 525 mm on all but the RV-30 vertical - where the depth of the head caused it to be reduced to 500 mm.
Both horizontal and vertical spindles were fitted with an ISA 50 nose, though that on the ram vertical head having a choice of an ISA 30 or 40. Drive came from either an 11 or 15 kW motor mounted inside the main column with drive to the hardened and ground spindle on the higher speeds directly by multiple V-belts. Lower speeds were sent though a 8:1 splash-lubricated lathe-like backgear system, the final gear of which was carried on the spindle immediately behind the front double-row selected high-precision roller bearings (its weight being designed to add to the flywheel effect of the drive). With a single-speed motor running at 1400 r.p.m. twelve speeds were provided that ranged from 31 to 1000 r.p.m. (or twice as fast with the 2800 r.p.m. option). Also available, though on the vertical model only, was a two 2-speed 1400/1800 r.p.m. motor that gave 22 speeds from 31 to 2000 r.p.m. The twelve horizontal spindle speeds RE-30-VS and RU-30-VS were slightly different - running from 56 to 2800 r.p.m. - with the vertical ram head having its own 2-speed motor producing twelve speeds from 28 to 2800 r.p.m..
