As a further improvement of the invention, the blocking plug is vertically inserted into the side hole.

As a further improvement of the present invention, the processing tool further comprises a grinder.

As a further improvement of the present invention, the grinder includes a grinding spindle and a grinding wheel.

As a further improvement of the invention, the brittle material is a rotating target workpiece.

The processing tool for the ITO brittle material clamps the brittle material with proper force aiming at the long brittle material, improves the machinability of the brittle material, has high yield and stable grinding quality of the brittle material.

Detailed Description

The technical solutions will be described clearly and completely in the following with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 and 2, a processing tool 100 for ITO brittle materials is used for processing an ITO target 200, wherein the ITO target 200 is a cylindrical workpiece with a length of 1000 mm; the processing tool 100 includes a main pusher 110, a pad 120, a support 130, and a grinder 140.

The main pushing device 110 includes a force rod 111, a circular disc 112 connected and fixed to one end of the force rod 111, a plurality of fixing screws 114, and a plurality of claw hook sets 113 fixed to the other surface of the circular disc 112 through the screws 114, in this embodiment, the main pushing device 110 includes two claw hook sets 113. Each of the claw hook sets 113 includes three claw hooks 113a having the same length, the claw hooks 113a of different claw hook sets 113 have different lengths, each of the claw hooks 113a includes a straight portion 113a1 and an inclined head 113a2, and the straight portion 113a1 is fixed to the screw 114.

The backing plate 120 includes a plurality of first through holes 121 extending therethrough, and each of the hooks 113a extends through the first through holes 121.

The bracket 130 includes a first end 131, a second end 132, and a middle portion 133 connecting the first end 131 and the second end 132, each of the first end 131 and the second end 132 includes a plurality of second through holes 136 penetrating back and forth and a side hole 135 opened at a side and communicating with the second through holes 136, the bracket 130 further includes a plurality of cylindrical stoppers 134 capable of being vertically inserted into the side holes 135, each stopper 134 includes a third through hole 134a penetrating obliquely, and each claw hook 113a is capable of penetrating the second through hole 136 back and forth and being inserted into the third through hole 134 a.
