GEPY Centres
and Spindles
These superb
revolving (live) centres employ roller bearings that form an
integral part of the centre itself. The taper and needle roller
bearings bear directly on the completely hardened and ground
shaft allowing a larger diameter shaft to be employed without
compromising compactness. This produces a centre with little
overhang and thus great rigidity. GEPY centres are self adjusting
and sealed from the ingress of foreign matter. The maximum eccentricity
of the centre is guaranteed to be not greater than 0.002mm due
to the careful selection of the rollers and also the special
grinding process which ensures the perfect accuracy of the spindle
taper.
GEPY centres are available in four types:
- Type P (as illustrated above) with standard 60 degree point
- Type COP with reduced diameter point (largely intended for copier work)
- Type C with female (inverted) point
- Type K with large diameter inter-changeable points (for supporting tubular work)
GEPY centres are available with the following taper shanks:
- Morse tapers 1, 2, 3, 4, 5
- Schaublin 70 2 degree
- Schaublin 102 2 degree
- Mikron and other tapers

| In addition to their famous revolving centres GEPY also produce a number of different styles of high precision spindles for milling, drilling and grinding operations. These exquisitely made spindles are highly complementary to Schaublin and Aciera machines and in some instances were supplied by the manufacturers as original equipment. The B8 spindle (right) was supplied as Schaublin part number 70-89.150 (see archive) and has a maximum speed of 15000 rpm. It accepts B8 (8mm horological) collets. |  |
