Problems solved by technology

[0002] In the field of semiconductor processing, there are many double-sided slender rectangular parts. The shape of the part itself determines that the structure of the part is unstable and easy to vibrate in the free state, and it is easy to vibrate and overcut during processing. Longer, multiple vises are needed to clamp, and multiple jaws need to be straightened within 0.03mm as a whole, which consumes a lot of time, and only one part can be processed in one clamping, and the processing efficiency is low

Embodiment

[0030] 1. Double-sided slender rectangular parts (such as figure 1 As shown), there are stations on both the front and back of the part, the width of the part is about 8mm, the thickness is about 11mm, and the length is about 1000mm. The part in the free state is very easy to vibrate and bend.

[0031] 2. If figure 2 As shown, 10 parts are arranged in a row, and the distance between the parts is the same as 8.5mm. 1) Use a φ100 disc cutter to mill the upper and lower parts of the part to ensure that the thickness of the part is 11±0.1mm; 2) The front chamfer is 0.4mm, and the φ8mm cutter is used to mill the sinking depth of 1mm (as the avoidance area of ​​the chamfering cutter).

[0032] 3. (such as image 3 As shown) Turn over the entire size of the part to be processed, and reserve the connecting ribs when cutting to avoid parts vibrating and overcutting the parts. The spacing of the connecting ribs is 150mm, the width of the connecting ribs is 5mm, and the thickness is 1...

Abstract

The invention provides a machining technology of a two-sided long thin rectangular part and belongs to the field of cold machining. By means of a targeted machining scheme, the two-sided long thin rectangular parts are arranged and machined, clamping and aligning are conducted once, and the multiple parts are machined at the same time. Since the multiple parts are arranged and machined, clamping and aligning are conducted once, and the multiple parts are machined at the same time, the clamping time, aligning time, tool setting time, tool changing time and the like of each part can be saved, and the machining efficiency of the parts is greatly improved. Due to uniform reservation of connection ribs, the stability of the parts is effectively controlled in the machining process, the situationthat the parts shake in the machining process, so that the parts are excessively cut and even scrapped is avoided, the quality stability of the parts is guaranteed, and the practicability is high.

Description

technical field [0001] The invention belongs to the field of cold processing industry, in particular to a processing technology of double-sided elongated rectangular parts. Applicable to the equipment used in the electronic industry, it is a professional technology for cold processing of double-sided slender rectangular parts. Background technique [0002] In the field of semiconductor processing, there are many double-sided slender rectangular parts. The shape of the part itself determines that the structure of the part is unstable and easy to vibrate in the free state, and it is easy to vibrate and overcut during processing. Longer, multiple vises are required to clamp, and multiple jaws need to be straightened within 0.03mm, which consumes a lot of time, and only one part can be processed in one clamping, and the processing efficiency is low. In order to solve this problem, it is necessary to develop a processing technology for double-sided slender rectangular parts. C...
