・
Process the engagement diameter of the back plate after measuring the actual
spindle.
・
Run-out of the back plate directly affects the process precision. The end surface
run-out of the back plate, spigot joint diameter run-out must be 0.005 mm or less.
・
The precision of the processing of the chuck attachment end surface of the back
plate and the spigot joint diameter can be raised by processing them after mounting
to the installed machine.
・
Process the chuck attachment spigot joint diameter of the back plate at the target
value A-0.01 in the dimension A of Table 9.
