仕上げることができる。[Operation] According to the present invention, the grinding machine (pulling table) is driven by a linear motor to perform grinding on the processing surface of the workpiece.
[In this case, the table moves in an orthogonal direction perpendicular to the table feeding direction due to fluctuations in the table feeding speed. If the table feed rate has a small variation, a narrow and shallow ground surface will result, and if the table feed rate has a large variation, a wide and deep ground surface will result. As a result, a larger uneven surface and a smaller uneven surface are generated on the machined surface of the workpiece, and then by not applying elastohydrodynamic lubrication treatment to the uneven surface, the smaller uneven surface is scraped off to create a bearing guide surface with high precision. can be finished.

A table 5 is placed on top, and the table 5 is moved in the left-right feeding direction as shown by the arrow in FIG. A magnetic chuck 7, which is a magnetic member for fixing the workpiece, is placed on the table 5, and the workpiece W is fixed on the magnetic chuck 7. A grindstone 11 attached to a grindstone head 9 facing downward is rotated by a drive device (not shown), and a predetermined grinding process is performed on a workpiece W fixed on a magnetic chirek 7. In addition, surface grinder 1
The grindstone 11 is not particularly unusual, and may be a conventionally used one.

凹凸面を生じる現象が生じる。As is clear from FIGS. 1 and 2, the surface grinder 1
When the table 5 is driven by the linear motor 13 to perform grinding on the workpiece W, the table 5 vibrates in a direction perpendicular to the feed direction due to speed fluctuations in the feed rate of the table 5, causing the workpiece W to be machined. A phenomenon occurs in which the surface becomes uneven as shown in FIG.

である。As shown in FIG. 3, the uneven surface is composed of a larger uneven surface Wa and a smaller uneven surface Wb. The larger uneven surface Wa is caused by vibration in the orthogonal direction (Y direction) orthogonal to the feed direction, which is the left-right direction (Y direction) in FIG. 3, due to a 7 degree change in the feed speed of the table 5.

As shown in the figure, when the machined surface Wd of the workpiece W becomes narrow and shallow and the speed fluctuation is large, the machined surface Wd of the workpiece W becomes narrow and shallow.
C becomes wider and deeper. The machined surface Wc of such a workpiece W
, Wd, the relationship between the speed fluctuation and the uneven surface is as shown in FIG.

で行なわれる。Above) As a means to increase the speed fluctuations in the feeding speed of the double 5, in controlling the linear motor 13, etc., a small speed fluctuation Vd is caused at the maximum constant speed of the speed command diagram shown in FIG. This is done by stirring or applying a speed loop. In addition, as a mechanical means, for example, in the case of a linear pulse motor, this is accomplished by increasing the pitch and decreasing the girdle so as to greatly increase the torque fluctuation.

案内面が高開度に仕上がる。The above processing method results in a machined surface of the workpiece W as shown in Fig. 3, but since it cannot be used as a bearing guide surface in that state, normal elastohydrodynamic lubrication is further performed to create a smaller uneven surface Wb. By removing this, the bearing guideway can be finished with a high opening.

The workpiece placed on the table is vibrated in orthogonal directions to perform grinding, and then elastohydrodynamic lubrication is applied to the uneven surface of the workpiece.
