Basic requirements for machine tools for high-precision superhard
cutting grinding wheels
The equipment used for high-precision ultra-thin cutting grinding
wheels is mainly cutting machines and dicing machines, mostly
imported CNC equipment. The dicing machine mostly uses an integral
cutting grinding wheel, which has high rotation speed and small
cutting depth; the cutting machine has a wide range of applications
and can cut and precision groove. The basic requirements for
machine tools for high-precision superhard cutting grinding wheels
are as follows.
(1) High rigidity The dynamic and static rigidity requirements of
various components such as the bed, grinding wheel frame, and feed
system of machine tools are high, generally more than 50% higher
than that of ordinary grinders.
(2) The accuracy of the high-precision grinding wheel spindle must
be higher than that of ordinary grinding machines. Generally, the
spindle movement is required to be ≤0.002 mm and the radial runout
is <0.003 mm.
(3) The rotating speed is generally adjustable from 3 000 to 60 000
r/min.
(4) Good vibration resistance, the axis display and the machine bed
should have good vibration absorption performance
(5) Flexible feed system The system runs smoothly, has high
precision and adjustable speed.
(6) High degree of automation It has functions such as automatic
tool setting, automatic monitoring, and automatic compensation.
(7) Adequate cooling Multiple nozzles, large flow rate and high
pressure supply are available.
