Abstract

The invention provides a device for trimming the end surface of a knife holder, and the device is used for trimming the end surface (5) of the knife holder mounted on a main shaft (6) of a cutting machine. The device comprises a fixed part, as well as a knife trimming plate (4) and a control part which are fixed on the fixed part, wherein the control part is used for controlling the knife trimming plate (4) to move in a reciprocating manner in an X direction which is vertical to the axle center of the main shaft (6) during the rotation of the main shaft so as to trim the end surface (5) of the knife holder, and the final jumping precision on the end surface of the knife holder can be ensured by eliminating the assembly errors of the end surface of the knife holder and the main shaft.

Description

technical field [0001] The invention relates to the field of manufacturing integrated circuit packaging equipment, in particular to a tool seat end face trimming device for trimming the end face of a tool seat installed on a main shaft of a cutting machine. Background technique [0002] A cutting machine is a device that divides a wafer into circuit units, and is a key device for semiconductor post-packaging. The working mechanism of the cutting machine is powerful grinding, and the main shaft is the executive part of powerful grinding. Since wafer cutting requires high spindle speed, high precision and high stability, an aerostatic electric spindle is usually used, and the runout of the spindle tool holder is required to be less than 2 μm. In order to ensure the runout accuracy of the spindle end face, the end face of the tool holder is usually ground with a surface grinder in the processing stage, and the end face of the tool holder is manually ground on a grinding plate ...
