Structural layout of CNC cylindrical grinding machine

Time:2019-09-26 Visits:956
The CNC cylindrical grinder is mainly composed of grinding wheel frame, head frame, bed body, worktable, tail frame and other components during the production process. The bed body of the CNC cylindrical grinder adopts large circular holes and shark fin shaped rib plates. After long-term use, the machine tool has good dynamic and static stiffness.


The worktable of the CNC cylindrical grinder is divided into upper and lower tables, which can grind conical surfaces. The bed of the equipment and the guide rails of the worktable use plastic coated guide rails, which have a low friction coefficient. The workbench is directly driven by a servo motor to move the ball screw, ensuring smooth and reliable movement.


The grinding wheel linear speed of the CNC cylindrical grinder is less than 35m/s, and its overall grinding efficiency is relatively high when in use. The grinding head bearing is a large wrap angle three piece tile dynamic pressure bearing, with high rotational accuracy. The movement of the grinding wheel holder (X-direction) is directly dragged by a servo motor and ball screw, with a minimum resolution of 0.0005mm.


When the CNC cylindrical grinder is used in the radial vector machine, the measured values are automatically input into the CNC system. The CNC system sends a signal to rotate the X-direction servo motor, driving the ball screw to reach the given position, so that the size of the ground workpiece can reach the required position stably. The size dispersion of the batch ground workpiece is less than 0.003mm.

The CNC cylindrical grinder mainly adopts its layout of mechatronics integration structure during use, using work area protection or overall protection, which is easy to maintain and meets the requirements of human-machine engineering. The grinding wheel spindle system has high rotational accuracy and strong rigidity. The linear speed of the grinding wheel can reach 60m/s; The linear speed of CBN grinding wheel can reach 80m/s.

When using CNC cylindrical grinding machines, various forms of diamond dressing devices can be effectively selected, which can achieve precise CNC dressing and automatic compensation. Active measurement devices are configured to achieve full closed-loop control of grinding processing.
