Heat-deformable spindle base of a chen-ning rack with a slant-type bed

摘要

The present invention effectively blocks the thermal deformation of the main spindle in consideration of the inclination of the bed and the moving direction of the tool, thereby improving the machining accuracy during machining of the workpiece by eliminating the change in machining time.;To this end, according to the present invention, the heat insulating plate 3 is installed on both side surfaces of the main shaft-to-body base 2 mounted on the bed 1 having the slant with respect to the base surface and perpendicular to the bed 1 slant surface And a main shaft body (5) is provided on the main shaft body base (2) provided with the heat insulating board (3) so that the center of the main shaft (4) is on the extension of the upper surface of the heat insulating board It is the anti-deforming headstock of the Mr.-Yen-san shelf with.
