Problems solved by technology

[0006] However, for example an unskilled operator may not know or forget to tighten the opposing screws serially, but instead, for example in a circumferential sequence, resulting in the grinding wheel not being properly mounted to the grinding device wheel seat
[0007] If the grinding wheel is not properly mounted to the wheel seat, there is a possibility of damage to the spindle due to deformation of the fastening bolts, or the grinding wheel rotates off-center

Abstract

The invention provides a grinding wheel. The grinding wheel can be properly fastened to a wheel stand of a grinding device by any of workers. The grinding wheel is detachably disposed on a wheel stand fixed to a tail end of a main shaft of a grinding device. The grinding wheel is characterized by comprising an annular wheel pedestal and multiple grinding tools, wherein the annular wheel pedestal has a mounting part disposed on the wheel stand and also has a free end part opposite to the mounting part, the multiple grinding tools are configured on the free end part of the annular wheel pedestal, and multiple internal screw thread parts for screw connection with fastening bolts are formed in a separate manner along the circumference of the mounting part of the annular wheel pedestal. The grinding wheel is provided with fastening order display marks that show fastening orders of the internal screw thread parts.

Description

technical field [0001] The present invention relates to a grinding wheel detachably attached to a wheel base of a grinding device. Background technique [0002] Multiple devices such as ICs and LSIs are formed on the surface of the semiconductor wafer, and each device is divided by a predetermined dividing line (spacer), and the semiconductor wafer is processed to a specified thickness by grinding the back surface of the semiconductor wafer with a grinding device Afterwards, the semiconductor wafer is divided into individual devices by cutting the dividing line with a dicing device, and the divided devices are widely used in various electronic devices such as mobile phones and personal computers. [0003] A grinding device for grinding the back surface of a wafer is provided with: a chuck table holding a wafer; a grinding tool for grinding the wafer; and a grinding liquid supply member which supplies the grinding liquid to the grinding area, and the grinding device can grin...
