SMID RE-24 & SRE24  Lathes


Built in Mulhouse, France, by the SMID Company, the 120 mm centre height RE-24 capstan lathe was a compact, very simple but heavily constructed (380 kg) machine with its bed, 152 mm wide, cast as-one with the stand. Just 470 mm deep and 1100 mm long - it was intended for short-run batches and entirely hand-operated. Held in the stand, on a hinged plate, the 1 h.p. motor drove the spindle directly by a flat belt with just three speeds provided as standard: 500, 1000 and 1500 r.p.m. However, the makers hinted that other ranges could be arranged to suit a customer's particular requirements.
Running in precision bearings, the 30 mm bore headstock spindle took direct-fitting collets, opened and closed by a toggle-action lever (that emerged through the front face of the headstock), with a maximum through bore of 24 mm.
Guided on a bed with two rather tall V-shaped ways, the six-station turret assembly had a maximum stroke of 80 mm, was indexed by a 4-spoke capstan handle and had the usual six individually adjustable screw-type length stops. The 80 mm travel, lever-operated cut-off (forming) slide was also of conventional design and appearance - though very deep in section, with the middle cut away to give clearance for the capstan-head tooling. Fitted as standard with front and rear toolposts, each fitted with a screw-adjustable stop, the option of a 4-way indexing toolpost was also offered, a useful addition when capstan tooling could not be suitably arranged for the turning of multiple diameters.
A range of accessories was offered that included a set of twelve collets from 4 to 24 mm bore, capstan tooling such as die holders, quick-release die heads, box turning toolholders (roller steadies) of various kinds, floating reamer holders, recessing toolholders, bit holders, tap holders, drill chucks, etc. Also listed were coolant equipment and fittings, a light unit and a weight-operated bar-feed assembly.
Towards the bottom of the page are some details of the electrical system, contributed by a machine tool enthusiast, that other owners might find useful.

3-speed changeover switch

Since the condition of motor/switchgear/wiring is questionable, the motor, switchgear and associated wiring have been removed and are being replaced with a modern 3-phase motor and VFD drive which incorporates a speed-variation ability.
On the right-hand outer end face of the cabinet stand, a suds pump is mounted on a bracket bolted to the stand

On, Off, Forward and Reverse Switch

The heavy-duty coolant pump - dated 1940.  The trough for the suds is formed in the right hand bottom of the cabinet.



Coolant pump motor specification plate

The main drive motor specification plate.
As can be seen, it is a 3-speed motor running on 380v 3-phase. As a consequence, it is both large and heavy, weighing 50 kg.
The switchgear for speed change is heavy duty and complex:
