It is a high-efficiency automatic machine tool suitable for complex parts processing, which consists of mechanical equipment and numerical control system. It can be said that it is one of the CNC machine tools in the world, with the highest output and the most extensive application. Its comprehensive processing ability is relatively strong. After the component is clamped at one time, more processing contents can be completed, and the processing accuracy is higher. For medium-difficult batch components, the processing efficiency can reach 5~10 times that of general processing equipment, especially for general equipment. For the processing tasks that cannot be completed, it is more suitable for single-part processing with complex shapes and high precision requirements or small batch and multi-variety production. The device integrates the functions of milling, boring, drilling, tapping, thread cutting, etc., and has various technological means for processing procedures.
According to the spatial position of the spindle during processing, the machining center is divided into a horizontal machining center and a vertical center. According to the technical use, it can be divided into: boring and milling machining center, compound machining center. Special functions are divided into: single table, double table, multi table machining center. Machining centers with single, double, triple and exchangeable headstocks. According to the classification of the track, it is divided into: linear track machining center, hard track machining center, etc.
High-speed milling machine
Compared with the machining center, the movement speed and feed rate of the high-speed milling machine are faster. The spindle speed of about 30000RPM is 30000RPM. The processing and response speed of the CNC system is obviously better than that of the machining center. Therefore, small diameter milling cutters can be used, high speed, The cutting process with small cycle feed greatly improves production efficiency and machining accuracy. At the same time, because the processing and response speed of the numerical control system are significantly improved, small-diameter milling cutters, high speed, and small cycle feed can be used for cutting. processing.
High-speed milling is generally a foreign imported product, suitable for the processing of most precision molds and the processing of high-precision copper and graphite electrodes. Using high-speed milling process, 60HRC hardened steel parts can be machined. Therefore, high-speed milling can be processed after heat treatment, thereby reducing the processing workload.
CNC engraving machine
CNC engraving machine has some connotations of high-speed milling machine, the spindle speed can reach about 30000RPM, but the spindle power is much smaller than that of the machining center. The high spindle speed is suitable for the processing of small tools, the torque is small, and it focuses on the “cutting” function, which is not suitable for strong cutting. Soft metal can be micro-machined, but its machining accuracy is high, and its disadvantage is that it is not suitable for heavy cutting due to poor rigidity. Due to the concentration on small parts, the machine is also much smaller than machining centers and high-speed milling. It is mainly used in copper electrode processing in mold industry, batch processing of aluminum products, wood mold processing, etc.
Reduce the cost of CNC machined parts
CNC machining is a great method when you want to build prototypes or mass-produce end products. But disposal costs are often the main reason people stop using them. There are several factors that affect the cost of CNC machined parts, including material, design, finish, quantity, and turnaround time. Fortunately, professionals with extensive CNC machining experience can greatly help you reduce cutting costs and final product prices.
What factors affect the cost of CNC machined parts?
Before discussing how to reduce costs, a brief overview of six factors that affect the price of CNC parts can be made.
The longer it takes to process these parts, the more expensive it will be. Machining time is often the main cost driver for CNC machined parts.
The prices of various raw materials tend to vary. Some materials with similar properties but not commonly used, the price will be much higher.
Tighter tolerances will result in more difficult machining and will increase scrap rates, which in turn will lead to higher prices.
It takes the same amount of CNC programming time to make 1 and 1000 parts, so that when more is required, the total cost can be shared equally, thus reducing the cost per product.
If surface treatments such as coating, smoothing, anodizing, and black oxidation are required, multiple processes are required and the cost is high.
Shorter lead times mean that suppliers need to schedule your order right away and have to delay the processing of other orders. This is a small factor when it comes to expedited processing fees, which the industry calls expedited processing fees.
