Embodiment Construction

[0013] As shown in Figures 1 and 2: 10 is the magnetic workbench of the three-axis grinding machine, the magnetic force workbench 10 is made to generate magnetic force through the control device, and the linear guide rail 13 is fixed at the same time. The linear guide rail 13 shown in Fig. 2 is its cross-sectional view, 11 Is the top surface of the linear guide, 12 is the bottom of the linear guide, and 14 is the two sides of the linear guide. There are arc-shaped raceway working surfaces 8 on both side surfaces 14 of the linear guide rail, and the bottom of the raceway working surface 8 is processed with a retaining steel wire groove 9 .

[0014] First, machine the top surface 11 of the linear guide rail, the bottom surface 12 of the linear guide rail, the two side surfaces 14, the working surface of the raceway 8, and the retaining wire groove 9, and leave a certain amount of grinding allowance. Generally, the grinding allowance is controlled at 0.3~ between 0.4mm.

Abstract

The grinding process of rolling linear track includes the following steps: 1. grinding the top of linear track with a surface grinding machine; 2. inverting the linear track and fixing magnetically on the magnetic work bench of a three-axis grinder; 3. correcting the work surfaces of the right grinding wheel and the left grinding wheel and the work surface of the middle grinding wheel with corresponding correcting devices; and 4. grinding the side surfaces, the roller track surface and the bottom of the linear track simultaneously with grinding wheels. The present invention has high machining precision, high machining efficiency and other advantages.

Description

technical field [0001] The invention relates to a grinding method of a workpiece, in particular to a grinding method of a rolling linear guideway. Background technique [0002] The machining accuracy of the top surface, bottom surface, side surface and the raceway working surface on the side of the rolling linear guide is relatively high. Usually, it is rough-machined first with a certain grinding allowance, and then ground to make it reach the design. accuracy requirements. The current grinding method requires multiple processes. First, use a surface grinder to grind the top surface, bottom surface and both sides of the linear guide rail respectively, and then use the ground bottom surface to fix the linear guide rail on the workbench of the grinding machine again, and correct the side. The forming grinder is equipped with two sets of correction devices, and the two grinding heads grind the raceway working surfaces on both sides of the linear guide respectively. This mult...
