What’s CNC machining?

CNC machining stands for computer numerical control.CNC machine tool programming controlled by CNC machining language. What kind of Cartesian position coordinates are used for the processing tools of the CNC machine tool, and control the feed speed and spindle speed of the tool, as well as the tool changer, coolant and other functions. Compared with manual machining, CNC machining has great advantages. CNC machining can produce parts faster, more accurately, and more accurately, and can produce parts with complex shapes that cannot be completed by manual machining. CNC machining has also reduced the labor cost of manual processing that was originally done by humans.

What are the benefits of CNC machining?

① The number of tooling is greatly reduced, and complex tooling is not required for processing parts with complex shapes. If you want to change the shape and size of the part, you only need to modify the part processing program, which is suitable for new product development and modification.

②The processing quality is stable, the processing precision is high, and the repeat accuracy is high, which is suitable for the processing requirements of the aircraft.

③The production efficiency is higher in the case of multi-variety and small batch production, which can reduce the time of production preparation, machine tool adjustment and process inspection, and reduce the cutting time due to the use of the best cutting amount.

④It can process complex profiles that are difficult to process by conventional methods, and even process some unobservable processing parts.

⑤Reduce the labor cost of manual processing that was originally done manually

However, due to the high cost of CNC machine tools and the requirement for high-level technical personnel, the cost of machining will be relatively high.

What is the difference between zinc plating,nickel plating and chrome plating?

Electroplating is the process of using electrolysis to attach a metal film to the surface of metal or other materials to prevent metal oxidation, improve wear resistance, conductivity, light reflection, corrosion resistance and aesthetics.

Electroplating is divided into gold plating, silver plating, chrome plating, nickel plating and zinc plating. it is usualy use zinc plating, nickel plating and chrome plating in the field of metal manufacturing.

What is the difference between them?

zinc plating: Galvanizing refers to the surface treatment technology of plating a layer of zinc on the surface of metals, alloys or other materials for aesthetics and rust prevention.
Features: low cost, general anti-corrosion, silver white.
Application: screws, circuit breakers, industrial supplies, etc.

Nickel plating: A method of plating a layer of nickel on metal or certain non-metals by electrolysis or chemical methods.
Features: beautiful, can be decorated, high price, slightly complicated craftsmanship, the color is silvery white and yellow.
Application: Energy-saving lamp holder, coins, metal parts, etc.

Chrome plating: Chromium is a kind of bright white metal with a bluish tint. It is a method of plating a layer of chromium on metal or some non-metals by electrolysis or chemical methods.
Features: There are two types of chromium plating. The first one is for decorative purposes. It has a bright appearance and good abrasion resistance. The anti-rust ability is not as good as galvanized and is worse than oxidation. The second is to increase the hardness and wear resistance of metal parts. .
Application: Bright decorative parts, tools, faucets, etc. on home appliances, electronics and other products.

In a word, the biggest difference between them as following :
1. Chrome plating is mainly to improve surface hardness, beauty and rust prevention. The chromium plating layer has good chemical stability, and has no effect in alkali, sulfide, nitric acid and most organic acids
2. Nickel plating is mainly wear-resistant, anti-corrosion, and anti-rust, and generally has a thinner thickness.
3. Galvanizing is mainly beautiful and anti-rust. Zn is an active metal that can react with acid, so it has poor corrosion resistance.

The operation life of tools is a problem in machining production

Currently, CNC manufacturing companies are facing many challenges in production:
1) Reduce the cost of individual parts to maintain competitiveness
2) Break through the bottleneck of processing
3) Improve metal removal rate
4) Improve the utilization rate of machine tools
5) Reduce tool clamping or tool changes

There must be a way to produce the component more cost-effective! Progress isn’t always big changes are needed every time. The progress in actual production is usually obtained by many small optimizations, but the benefits brought by it are greatly improved.

The extension of the operation life of tools and the enhancement of wear resistance and heat resistance can help minimize unexpected downtime, improve the safety, processing efficiency and productivity of the turning process, and reduce the waste of cemented carbide inserts and workpiece materials. It is a necessary condition to realize sustainable processing.

GC4425 tool is the material of choice for steel turning, and it performs better than competitors in most steel turning applications. The wear resistance, heat resistance and toughness of the new material have been improved.

And expand the scope of application:
1) Low alloy steel and non-alloy steel
2) Suitable for mass production
3) External and internal machining
4) Continuous cutting and slightly interrupted applications in finishing machining and roughing machining

The impact of the rising price of raw materials

What kind of impact does the rise of metal raw materials bring to CNC machining factory? In particular, metallic copper belongs to a variety that has a strong linkage with the international market. From March last year to May this year, the domestic copper price soared from around 35,000 yuan per ton to 75,000 yuan per ton.

As the epidemic swept the world last year, and then the world’s major economies continued to expand money supply to stimulate the economy, copper prices soared to the current more than 70,000 yuan, a record high in the past 15 years. Since May this year, copper processing companies have experienced a reduction in output, which is the same period in previous years. The raging production scene is in sharp contrast, production has been forced to slow down, and shipments have dropped significantly, resulting in a high inventory of finished products.

After the Spring Festival this year, global copper inventories increased by 200,000 tons year-on-year. In the same period of the previous year, the conventional inventory fell by 200,000 to 300,000 tons. The rapid increase in copper prices inhibited downstream processing demand. The increase in raw material prices, coupled with the superimposition of exchange rate, freight and other factors, As a result, the prices of some products have increased significantly.

Sellers are also actively making suggestions for customers to save transportation costs through methods such as sub-packaging by sea. In order to relieve pressure, business operators reduce the impact of rising raw materials through bulk purchases and storage of raw materials in advance. At the same time, actively develop domestic and foreign markets and diversify sales channels.
