Embodiment Construction

[0025] Hereinafter, a polishing technique according to an embodiment of the present invention will be described with reference to the drawings.

[0026] exist figure 1 , image 3 as well as Figure 5 In (a), the structure of the grinding machine for realizing the grinding processing technique of this embodiment is shown. The grinder includes: a grindstone 4 for grinding the workpiece 2; and a grindstone control system NC for relatively moving the grindstone 4 with respect to the workpiece 2. In this case, the grinder 4 is supported by a quill type support shaft 6 (feed shaft, servo shaft), and the support shaft 6 is assembled to a grinder main body 8 controlled by a grinder control system NC.

[0027] The grinding tool control system NC has: a workpiece element database 10 in which elements required for grinding of the workpiece 2 are registered in advance; Operation processing unit 12. In addition, as the workpiece 2, the inner ring and outer ring of a bearing are mentio...

Abstract

Teaching (teach-in) work is performed, and from said teach-in position (SX), the workpiece (2) is ground by only a prescribed "trial grinding amount (A)." Subsequently, the diameter of the workpiece is measured. Based on the results of the measurement, the residual amount to be ground so that the workpiece has the finished dimensions (residual grinding amount) is calculated and grinding by only said "residual grinding amount (R)" is performed.

Description

technical field [0001] The invention relates to a grinding processing technology. Background technique [0002] In the past, for example, in the process of manufacturing various workpieces such as raceway rings (inner rings, outer rings) of bearings, the inner diameter of a certain workpiece (such as the inner ring) was ground, and the inner diameter of other workpieces (such as the outer ring) was ground. The raceway grooves are ground. Various techniques have been proposed regarding polishing techniques for this purpose (for example, refer to Patent Document 1). [0003] For example, when switching the setting of the workpiece, the positional relationship between the grinding tool and the workpiece is set. In this case, in the conventional grinding processing technology, after setting the workpiece on the spindle, the feed shaft is manually operated, and teaching is performed in which the grinding wheel provided on the feed shaft comes into contact with the workpiece. O...
