Embodiment Construction

[0093] The content of the present invention will be further described below with an embodiment.

[0094] A common CNC surface grinder with horizontal axis and rectangular table. The vertical moving axis of the grinding wheel is the Y axis. The Y axis is controlled by the servo motor 7 through the reducer to rotate the ball screw 10. The ball screw drives the screw nut and the grinding wheel supporting mechanism connected with the nut. 11 Move up and down; the horizontal movement axis of the worktable is the Z axis, the Z axis is controlled by the servo motor through the reducer to rotate the ball screw, the ball screw drives the screw nut and the sliding seat connected to the nut to move, and the sliding seat supports the workbench for horizontal movement. Movement; the longitudinal movement axis of the workbench is the X-axis, and the X-axis is pushed by the push rod of the hydraulic cylinder to move the workbench on the sliding seat to move longitudinally; the motor of the ma...

Abstract

The invention provides a dynamic compensation method of the abrasion of a grinding wheel of a numerical control horizontal shaft surface grinding machine and relates to the technical field of numerical control grinding machines, particularly to a dynamic compensation technology of the abrasion of the grinding wheel of the numerical control horizontal shaft surface grinding machine. The active power of a main shaft or grinding head motor and for grinding is measured to indirectly calculate the abrasion of the grinding wheel and implement the dynamic compensation of the abrasion of the grinding wheel of the numerical control horizontal shaft surface grinding machine. The invention also provides a calculation method of the dynamic compensation of the abrasion of the grinding wheel of the numerical control horizontal shaft surface grinding machine. According to the dynamic compensation method of the abrasion of the grinding wheel of the numerical control horizontal shaft surface grinding machine, the dynamic compensation method is not affected by the shape of workpieces and limitations are avoided; only a main shaft motor active power transducer and a digital transmission device need to be added to a numerical control system and accordingly the cost of the added hardware is low; the machining efficiency of the numerical control surface grinding machine can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a dynamic compensation technology for grinding wheel wear of a numerical control horizontal-axis surface grinder. Background technique [0002] The radius of the grinding wheel of the horizontal axis surface grinder will gradually decrease during the processing, and the error caused will gradually increase. When the removal amount is large, one (batch) workpiece is not processed, and the error caused by the grinding wheel radius wear has far exceeded the tolerance of the workpiece. The ground parts are not only unqualified in height, but also in flatness, often appearing in the shape of a curved surface with a high middle and low sides. In reality (manual grinding machines and CNC grinding machines without grinding wheel wear dynamic compensation function) the solution to this problem is to use an intermittent feed much less than 1 / 2 the width of the grin...
