The Types of CNC Machining Materials We Can Provide
1. Metal materials: stainless steel, carbon steel (including various alloy steels), copper (including brass, red copper, beryllium copper, bronze and other special copper), aluminum alloy, titanium alloy and other special steel.
2. Insulation material: POM, nylon, acrylic, PC, PEEK, PF.
Part stainless steel products:
Steel grades that are resistant to weak corrosion media such as air, steam, water, etc., or have stainless properties are called stainless steels, and steel grades that are resistant to corrosion by chemical media such as acids, alkalis, and salts are called acid-resistant steels.
Generally, ordinary stainless steel is not resistant to corrosion by chemical media, but generally, acid-resistant steel is stainless. Stainless steel has good corrosion resistance and high hardness.
Part Al-alloy Products
Aluminum alloys are alloys based on aluminum with a certain amount of other alloying elements added. Aluminum alloys have the general characteristics of aluminum, and in addition, they have some alloy characteristics depending on the type and quantity of alloying elements added. Generally, aluminum alloys have good electrical conductivity, thermal conductivity, corrosion resistance, and weldability, as well as good casting properties and plastic workability.
Part Brass Products
Brass means an alloy composed of copper and zinc. Ordinary brass is only composed of copper and zinc, and if it is composed of more than two elements, it is called special brass. Generally, brass has strong wear resistance.
Part copper products
Pure copper is a soft metal. Copper has good ductility and good thermal and electrical conductivity.
Insulation material
The Types of Surface Finishing We Can Provide for CNC Machining
Zinc-plated, nickel-plated, copper-plated, dacromet, tin-plated, chrome-plated, gold-plated, silver-plated, blackened, anodized, and various special coatings.

Basic Guide to CNC Machining
Introduction to CNC Machining
CNC machining generally refers to the process of machining parts on CNC machine tools by issuing instructions from the control system to make the tool perform various movements that meet the requirements. CNC machine tools form relevant instructions in digital form to process parts. Therefore, in general, no human intervention is required in the working process, which also reduces errors to a certain extent.
Characteristics of CNC Machine Tools
CNC machine tools produce parts with high precision and high production efficiency. And it can adapt to the small-batch production of some parts, and can also adapt to the processing of relatively complex parts.
Why Choose CNC Machining
（1）High accuracy. The use of compensation technology in the work engineering of CNC machine tools can keep the machining accuracy at a high level. The accuracy of batch parts is improved as most of the operations are done automatically by the machine.
（2）High production efficiency. CNC machining reduces the operator’s labor, improves labor conditions, and effectively improves production efficiency.
（3）Strong adaptability. During the machining process, if a new machining program is reprogrammed, the machining of new parts can be realized immediately after inputting the new program without making any changes to the hardware part of the machine. No other complex adjustments are required, shortening the production preparation cycle.
（4）It has good economic benefits. For small batch production, the adjustment and inspection time of the machine tool can be reduced, and the direct cost can be saved. For mass production, the precision of CNC machine tool processing is relatively stable, which can greatly reduce the scrap rate and production cost.
The Operation Process of CNC Machine Tools
At present, the most mature field of CNC technology application is CNC machine tools. Machine tools refer to machines that make machines, and machine tools play a major role in economic development. Numerical control technology can provide good machine tool control ability, and the use of numerical control technology to process machine tools can improve product quality and production efficiency. CNC machining is an advanced way of mold manufacturing.
In the field of CNC machine tools, the operation steps are to edit the workpiece program and use digital codes to describe its dimensions, related parameters, and technological processes according to the parts processing drawings. Through code control, the position between the tool and the workpiece, selection of spindle, speed change, and tool are arranged in sequence. The processing information on the perforated paper tape is transmitted to the numerical control device through the photoelectric input machine, and then the numerical control computer sends out instructions, and the machine tool executes the instructions for production. If the processing object changes, the staff only needs to rewrite the processing program and does not need to adjust the machine tool itself. It has strong adaptability and is also conducive to the improvement of work efficiency.
