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.

What's the properties of POM?

Polyformaldehyde (POM) thermoplastic crystalline polymer. Known as "Super Steel" or "Sai Steel", The English abbreviation is POM. Generally, polymers obtained by formaldehyde polymerization have a low degree of polymerization and are easily thermally depolymerized. It can be used as a raw material for organic chemicals and synthetic resins, and as a fumigant for drugs. 1.General property POM is a hard, dense material with a smooth surface and gloss, light yellow or white, thin-walled partly translucent. Combustion characteristics are easy to burn, and continue to burn after leaving the ignition source. The flame is yellow at the upper end and blue at the lower end. Melting dripping occurs and has a strong pungent formaldehyde smell and fishy smell. POM is white powder, usually opaque, good coloring, specific gravity 1.41-1.43 g/cm3, molding shrinkage 1.2-3.0%, molding temperature 170-200℃, drying conditions 80-90℃ for 2 hours. POM's long-term heat resistance ...

What is 'Catch hook and thin-wall' of plastic mold products?

What is 'Catch hook and thin-wall' of plastic mold products ? 1. The Catch hook The catch surface and the amount of catch hook are the important basis for the test data during assembe. Once made any tiny mistake about these numbers, It would become a huge mistake of the product. Therefore, during mould design, We needs to pay special attentin to the catch hook assembly and testing. 2. The thin-wall What is the big problem about thin wall? The binding point is particularly easy to press and brittle, Then could't pass the test. It will be difficult to assemble in the next step, The product will be uneven filling, shrink, and easy broken.

Useful Tips for Custom Titanium Manufacturing

JY Machinery offers high-quality precision and cost-effective CNC machining services for custom titanium parts to enhance manufacturing efficiency. Custom Titanium alloy manufacturing is mainly used for the production of aircraft engine compressor components, followed by the structural parts of rockets, missiles and high-speed aircraft, and related medical accessories. The density of titanium alloy is generally about 4.51g/cm3, which is only 60% of steel. The density of pure titanium is close to that of ordinary steel. Some high-strength titanium alloys exceed the strength of many alloy structural steels. Therefore, the specific strength (strength/density) of titanium alloy is much greater than other metal structural materials, and parts with high unit strength, good rigidity and light weight can be produced. The aircraft's engine components, skeleton, skin, fasteners and landing gear all use titanium alloys. The Reasons Why Titanium Is Hard to Machine If you want t...
