A catalogue is available for the Kamph tool & cutter grinder
Michael Kamph KG of Bad Homburg V.D.H., in Germany, were manufacturers of specialised, high-precision machine tools. By the 1960s their range of products included die and mould copy milling machines types FK1, FK2a, FK3, the Model B 111 engraving machine, the A 111 SUPRA geometric lathe, Model SL 1 cutter grinder and lapper, a medallion ruling machine the Model C 111, the Model SP 18 column pantograph, a rubber roller engraving machine the WG1, a step-and-repeat machine the H111, a tranfer press TP 1 and, the subject of this short description, the S 1V tool and cutter grinder.High-resolution pictures - may take time to open
Very similar in design and function to the better-known Deckel SO and SOE types (though a little larger and heavier), the compact and self-contained, the S 1V was powered by an enclosed, 0.2 kW (0.4 h.p.) motor running at 2800 r.p.m. with the grinding wheel spindle, driven by a small V-belt, rotating at 4750 r.p.m. To hold workpieces - slot drills, multi-faceted end mills, reamers and similar cutters - the work head was fitted with a 24-position indexing spindle bored to accept No.2 Morse taper shank cutters. Parallel shank cutters were held in collets (compressed by a screw-on nose-cap), the largest of which had a bore of 24 mm (15/16"), The workhead was arranged to move, by a crank-handle equipped feedscrew, though 80 mm (3.125") - this being the maximum length of grind that could be managed. In order to set the grinding radius (the maximum was 20°) the head could be moved laterally across the arm, again by a screw fitted with a small, full-circle handwheel.
Other settings - cutting angles of up to 45° and clearance to the grinding wheel of up to 160 mm (6.375") - were achieved by the arm being mounted on a boss fitted with a double swivel housing, the housing itself able to be driven along a slideway, set parallel to the base, by a fine-feed screw fitted with a micrometer dial that allowed settings as fine as 0.01 mm (0.0004") to be achieved.
To summarise the working and clamping capacity of the Kampf S 1V:
Maximum cutting angle: 45°
Maximum radius: 20 mm (0.75")
Maximum grinding length: 80 mm (0.75")
Maximum clearance: 160 mm (6.375")
Axial adjustment of dividing head 150 mm (6")
Axial movement of grinding spindle: 30 mm (1.1875")
The machine was 700 mm (28") long, 450 mm (18") wide, 630 mm (25") tall and weighed a considerable 65 kg (140 lbs)..
