Machining expenses of Hangzhou Yuchen
Hangzhou Yuchen Machinery Co., Ltd.: after more than ten years of joint efforts and continuous development of all employees of Yuchen, we are specialized in precision mechanical parts processing and precision optical processing! Machining refers to the process of changing the dimension or performance of the workpiece through a kind of mechanical equipment. According to the difference of machining mode, it can be divided into cutting and pressure machining. Scope of application: all kinds of metal parts processing; sheet metal, box, metal structure; titanium alloy, high temperature alloy, non-metal machining;
(4) The polishing process should be completed in two working places, i.e. the rough grinding processing place and the fine polishing processing place, and pay attention to cleaning the sand left on the workpiece surface in the previous process. Generally, after rough polishing from oilstone to 1200 × sandpaper, the workpiece needs to be transferred to a dust-free room for polishing to ensure no dust particles in the air adhere to the mold surface. The polishing process with a precision of more than 1 μ m (including 1 μ m) can be carried out in a clean polishing room. If a more precise polishing is to be carried out, it must be carried out in a clean space, because dust, smoke, dandruff and saliva are all likely to discard the high-precision polishing surface.
The second kind: three-sided milling cutter three-sided milling cutter abbreviated to three-sided edge: three edges have back angles, sharp edges, and light cutting. The three-sided milling cutter can be divided into straight tooth three-sided blade and staggered tooth three-sided blade. It is mainly used in horizontal milling machine to process step surface and shallow groove through one or two ends. In addition to the main cutting edge on the circumference, there are also auxiliary cutting edges on both sides of the three edge milling cutter, which improves the cutting conditions, improves the cutting efficiency and reduces the surface roughness. But after regrinding, the width changes greatly, and the three face milling cutter with inserted teeth can solve this problem.

2. To improve the cutting ability of cutting tools, the material and geometric parameters of cutting tools have an important influence on the cutting force and cutting heat. Correct selection of cutting tools is very important to reduce the machining deformation of parts. (1) Reasonable selection of tool geometry parameters. ① Front angle: under the condition of maintaining the strength of the cutting edge, the front angle should be larger. On the one hand, the sharp edge can be grinded, on the other hand, the cutting deformation can be reduced, the chip can be removed smoothly, and then the cutting force and cutting temperature can be reduced. Never use a negative rake tool.
First of all, check the process system itself. Process system is not a simple business chain, but a complex and closed circulation system, just like the blood circulation system. 1. Is the operation smooth? Such as the willful refusal of the responsible team leader. 2. Is the operation closed, broken or blocked? If the site complains, handle without permission and do not report. 3. There is no redundancy and inadequacy. Such as whether the final inspection has been carried out. 4. Whether it is formatted and normalized. Such as pick-up, delivery, quotation, no specification, no assessment standard, etc.
