Difficulties in processing precision medical parts

When processing medical parts board cnc medical parts to process precision medical parts, we must be fast, accurate and precise, but we will encounter difficulties during processing. Next, the editor will talk to you about the processing of medical parts board cnc medical parts processing and precision medical parts processing!

Because of its high-quality food resistance, formability, applicability, wide temperature durability and other characteristics, it is widely used in industry, light industry, daily necessities, architectural decoration design and other fields.

Carbon steel with a chromium content of more than 12% or a nickel content of more than 8% is called a medical parts plate.

This type of steel has certain corrosion resistance in air or corrosive substances, and can be applied at high temperature (>: 40°C), with high compressive strength. Steel with a chromium content of 16% to 18% is called acid-resistant steel or acid-resistant medical parts board, also known as medical parts board.

Due to the above characteristics, medical parts boards are more and more widely used in aviation, aerospace, chemical plants, crude oil, construction, fruits and other industries and daily life.

When processing medical parts boards, you will encounter the following difficulties:

Intense hardening: the plasticity of the medical parts plate is high, the plastic deformation is distorted, and the strengthening index is high; in addition, the martensite is not stable enough, and under the influence of drilling stress, a part of the martensite can be transformed into austenite; in addition, the compound The type residue is very easy to dissolve and disperse under the influence of cutting heat, resulting in a hard bottom layer after drilling. The processing hardening caused by the previous feed or the previous process seriously affects the smooth development of the subsequent steps.

High cutting speed: The plastic deformation of medical parts materials is large during the drilling process, resulting in an increase in cutting speed. The hardening of the medical parts board is relatively serious, and the heat intensity is high, which further enhances the frictional resistance of drilling, and is not easy to curl and break chips.

High cutting temperature: Large plastic deformation during drilling, large friction with CNC blades, and high cutting heat; a lot of cutting heat is concentrated in the drilling area and the contact page between the knife and chips, and the heat dissipation conditions are not good.
