Cross-slide screw or tool-slide screw?

The cross slide moves across the lathe axis; the upper tool slide sits on the swivel base and moves the tool at the set angle. Specify which slide is affected. For a screw and nut, send total length, threaded length, outside thread diameter, pitch or TPI, thread hand, end-journal sizes and nut mounting dimensions, plus photos.

A statement such as 8 TPI specifies pitch (3.175 mm); it does not by itself identify the thread profile or a compatible screw. Keep metric and inch versions separate.

SN 50: Cross slide (17) · SN 71: Cross slide (23)

SN 55 / SN 63 / SN 71: clutch slipping - adjustment and parts identification

The supplied operating-manual extract says the clutches are factory adjusted. Adjustment is needed only if the clutch slips and is performed after the clutch has cooled. A slipping clutch should not be used to regulate spindle speed.

For the arrangement shown in the SN 55-63-71 extract, looking through the rear opening, clutch A is left and B is right. The thrust nut is secured by a screw; turning it by 15 degrees reduces clearance by 0.083 mm. This is an incremental adjustment, not a universal clearance setting. Use the complete source procedure and verify the exact machine arrangement.

The engaged clutch must transmit without slipping; the disengaged clutch must not drive the spindle. Over-tightening can cause heating. Service and adjustment belong to a qualified technician with the machine safely isolated as required by the operation.

This extract is for SN 55-63-71. The supplied SN 50 documentation describes a different A/B orientation; do not transfer the directions to SN 50.
