Mounting on the lathe
The toolholder is removed and the grinder set up on
the top slide so that the fixing screws on the top slide
are through the slots; when the grinder is correctly
adjusted it is tightened in place with washers and nuts.
External grinding
For most external grinding the 60mm dia. grinding wheel, grain 80, hardness grade M, is used. The grinding
wheel is bolted to the arbor at the toolpost grinder, trued and should remain in this position until it becomes
worn out. The locating arbor with the mounted grinding wheel is clamped in the spindle by means of a draw­
in tube. To grind the workpiece, the toolpost grinder with rotating grinding wheel (4500 rpm) is fed in to the
slowly revolving workpiece until a slight grinding spark formation occurs. The longitudinal slide rest of the
toolpost grinder is then moved into the initial position.Apply a feed of maximum 0,1 mm with the cross slide
and engage the automatic feed. The grinding operation will proceed automatically.
Internal grinding
Replace the external grinding arbor by the internal grinding arbor. Smaller grinding wheels can be mounted
on the front end of the grinding arbor (6mm dia.) and secured by means of an M3 screw. Very small grinding
wheels (below 15mm) have a cast-in M3 type screw and can be screwed direct into the grinding arbor. If they
are equipped with cylindrical shanks, a suitable Lorch-Schmidt watchmaker's collet of type B8 can be inserted
into the spindle and clamped. These small grinding wheels also require dressing by the truing diamond.Adjust
for a spindle speed of 8000 or 12.000rpm internal grinding. The grinding operation is similar to that of ex­
ternal grinding.
Taper grinding
For taper grinding move the toolpost grinder with the top slide into the desired angular position. Adjust with
the cross slide. The fe!;ld for the longitudinal movement is controlled by turning the top slide handwheel.
NOTE!
An increase in operating temperature can occur during the first few hours, but this will not harm the spindle.
The temperature will automatically drop after a few hours.
Cleaning and servicing
The quill is of a dust-tight design and all bearings are lubricated for life. In spite of this, the dust clinging to
the toolpost grinder should be wiped off after use. When re-setting the tool post grinder from external to in­
ternal grinding or viceversa, the taper socket must be cleaned meticulously.
