Problems solved by technology

In the structure of this device, since a mechanism for reciprocating the workpiece rotary car is required, the device is relatively complicated and the device is relatively large.
In addition, productivity is poor because multiple workpieces cannot be ground continuously

Abstract

The present invention provides a centerless polishing device capable of efficiently polishing the outer circumferential surface and ends of a rod-shaped or cylindrical workpiece. This centerless polishing device is provided with a roll brush, a workpiece-rotating wheel, and a workpiece-loading member. The bristle material of the roll brush is monofilaments obtained from nylon resin containing abrasive grains. The particle size of the abrasive grains is selected from between F60-F240 or #240-#2000. The content of the abrasive grains is 10-40 parts by weight with respect to 100 parts by weight of the entire bristle material. With said configuration, favorable polishing is possible without marring the outer circumferential surface of the workpiece or generating new burrs or edge-sagging at the ends during polishing.

Description

technical field [0001] The present invention relates to a centerless grinding device for grinding a rod-shaped or cylindrical workpiece between a roller brush and a workpiece rotary car to grind the outer periphery of the workpiece. Background technique [0002] A centerless grinding device is known as a device for uniformly grinding the outer periphery of a rod-shaped or cylindrical workpiece. Such as Figure 8 As shown, the centerless grinding device includes: a rotating grinding body; a workpiece rotating car rotating in the same direction as the grinding body; and a workpiece mounting member arranged between the grinding body and the workpiece rotating car. When a workpiece is placed on the workpiece mounting member, the workpiece is rotated by the workpiece rotating vehicle, and the outer periphery of the workpiece is ground in contact with a grinding body rotating in the opposite direction to the workpiece. [0003] A centerless grinding device generally uses a rotati...
