Embodiment Construction

[0022] 1 The structure of the grinding device

[0023] figure 1 The shown grinding device 1 is a grinding device for grinding a workpiece 14 using a grinding unit 3 . Hereinafter, the structure of the grinding apparatus 1 is demonstrated.

[0024] Such as figure 1 As shown, the grinding apparatus 1 has: a base 10 extending in the Y-axis direction; and a column 11 erected on the +Y direction side of the base 10 .

[0025] A grinding feed unit 4 that supports the grinding unit 3 is disposed on the side surface of the column 11 on the −Y direction side. The grinding unit 3 has: a main shaft 30 having a rotating shaft 35 in the Z-axis direction; a housing 31 supporting the main shaft 30 in a rotatable manner; a motor 32 rotating and driving the main shaft 30 around the rotating shaft 35; a seat 33 connected to the lower end of the spindle 30 ; and a grinding wheel 36 mounted on the lower surface of the mounting seat 33 . The grinding wheel 36 can be attached to and detached f...

Abstract

The present invention provides a grinding device which is constructed at a low price. A grinding wheel (36) is rotated at low speed (for example, 10 rpm) while injecting air from the air nozzle (7) of a grinding device (1) for grinding a workpiece (14). The front end detection unit (5) is used to detect a segment grinder (360), and a counter (60) is used to count the number and the like of the segment grinder (360). Then, the count value counted by the counter (60) is compared with the number of segment grinders (360) pre-stored in the judgment part (61) to judge whether the segment grinder (360) has fallen off. The grinding device (1) does not need to have a motor or the like for rotating the grinding wheel (36) at a low speed, so that the grinding device (1) can be constructed at a low price.

Description

technical field [0001] The invention relates to a grinding device. Background technique [0002] As disclosed in Patent Document 1, a grinding wheel mounted on a grinding device for grinding a workpiece includes: a base; and a plurality of segment grinding tools arranged on the base with gaps therebetween. into a ring. [0003] When grinding the workpiece, the grinding wheel is rotated, the chuck table holding the workpiece is rotated, and the segment grindstone is inserted from the outer periphery of the workpiece toward the center. [0004] When the segment grindstone enters from the outer periphery of the workpiece, the segment grindstone may come off from the base due to impact or the like received by the segment grindstone. [0005] When there is a portion of the grinding wheel from which the segmented abrasives have come off, there is a problem that a circular arc pattern of an unground portion is formed on the surface to be ground, and a thickness difference occurs ...
