How is CNC PROCESS?

1. Overview of CNC Machining

Based on the development of a milling machine automatic processing equipment, the two processing technology is basically the same, the structure is similar.CNC milling machine with cutter base is called machining center.

2. The scope of function of CNC Machining

Good adaptability and flexibility in processing, and can process parts with particularly complex contour shape or difficult to control size.High processing precision, stable and reliable processing quality, numerical control device pulse equivalent is generally 0.001mm, high precision numerical control system can be up to 0.5 m, numerical control processing also avoid operator error.Production automation degree is high, can reduce the labor intensity of the operator.Conducive to production management automation.

3. Classification of CNC Processing in the factory

There are two kinds of CNC in the factory:

Ordinary CNC: less than 8000 RPM, can be a large tool, suitable for milling, drilling, boring, flying material and other type tolerance accuracy of more than 0.02 forming processing.
High-speed CNC: milling processing with surface roughness above Ra0.4 and profile tolerance accuracy above 0.005.

CNC is suitable for tungsten steel milling cutter, the surface needs coating, according to the work piece hardness selection.

4. Constraint relationship

1) The depth of the machining hole is proportional to the diameter of the knife.
2) It is difficult to ensure high perpendicularity in hard material processing.
3) Tool wear has a direct impact on the size of the work piece.

5. Relationship with process engineering
Select the appropriate type of machine according to the parts.

The polishing treatment methods for alumina ceramics

It has become very common for thick film integrated circuits to use alumina ceramics . Ceramic materials mainly made of alumina (Al2O3) have good conductivity, mechanical strength and high temperature resistance. It is a widely used ceramic at present. However, after the alumina ceramic is sintered and cooled, it does not mean the end of product processing. Some products do not meet the application requirements. Therefore, they need to be processed, such as size correction and polishing. The polishing treatment method of alumina ceramics is as follows: 1. Using laser processing and ultrasonic processing for grinding and polishing. 2. Use Al2O3 powder or diamond paste for grinding and polishing. 3. The method of glazing is required (suitable for products that require high surface smoothness). 4. Use diamond, silicon carbide, etc. harder than alumina to grind step by step from coarse to fine. 5. The surface of the material is processed by ion implantation. Ion implantation...

The solution of bubble issue during injection molding process

According to the causes of bubbles, the countermeasures are as follows: (1) When the wall thickness of the product is large, the cooling speed of its external surface is faster than that of the central plastic part. Therefore, as the cooling goes on, the resin at the central part shrinks and expands towards the surface, resulting in insufficient filling at the central part. This condition is called a vacuum bubble. Solutions mainly include: A) Determine the reasonable gate and gate size according to the wall thickness. Generally, gate height shall be 50% ~ 60% of the wall thickness of the product. B) Until the gate is sealed, a certain amount of supplementary injection material is left. C) The injection time should be slightly longer than the gate sealing time. D) Reduce the injection speed and increase the injection pressure; E) Use materials with high melt viscosity. 2) The bubbles caused by the production of volatile gases are mainly solved as follows: A) Sufficient pre-drying...

The application range of sandblasting treatment

Sandblasting is the process of cleaning and roughening the substrate surface by the impact of high-speed sand flow. Use compressed air as the power to form a high-speed jet beam to spray the blasting material (copper ore, quartz sand, corundum, iron sand, Hainan sand) at high speed on the surface of the workpiece to be processed, so that the appearance or shape of the outer surface of the workpiece surface changes. (1) Workpiece coating and sandblasting before workpiece bonding can remove all dirt such as rust on the surface of the workpiece, and establish a very important basic pattern on the surface of the workpiece (the so-called rough surface). By changing the abrasives with different particle sizes, the roughness of different degrees is achieved, which greatly improves the binding force of the workpiece with coatings and plating materials. Or make the adhesive bond more firm and better quality. (2) The rough surface of the casting, the cleaning and polishing of t...
