What is a small machining center?
What does the "small" of a small machining center mean, and where is it? Small in the shape of the head, small in the floor space, and small in the load-bearing workbench, these answers are actually not accurate. The small machining center actually refers to the processing stroke of the workpiece, which is what we often say can be made. The common small machining center model on the market is 650. Next, we will learn more about this type of machining center.
Product advantages of small machining centers
Scope of application:
Mass production and processing of medium-sized hardware parts, which can be drilled, tapped and milled. Suitable materials for copper and aluminum parts, castings, and steel parts.
Product introduction of processing center:
The small machining center adopts the mature and stable Taiwan Baoyuan CNC machining center system on the market, and is equipped with 20 hat type BT40 tool magazines (24 disc type BT40 tool magazines are optional). The product configuration is high, the accuracy is high, and the stability is high. It can cut larger products.
1. The structural design of large span adopts roller linear guide to increase the rigidity of the equipment;
2. Change the design of the tool magazine side hanging on the side of the column to be supported by the base to reduce the lateral force of the tool magazine on the column;
3. It adopts 24 Shengjie robotic arm tool magazine and BT40 mechanical spindle, which has a large cutting force;
4. The core components are all made in Taiwan, Taiwan Baoyuan system, Taiwan Danquan spindle, Taiwan Shangyin guide rail;
5. Adopt the absolute value servo feed drive motor, the traditional design without the stroke block, reduce the common overtravel alarm;
6. The equipment can have outstanding stable operation characteristics.
Many friends have reported that for the same model, why is there a big difference in prices between manufacturers and manufacturers? Are some manufacturers too dark? The asking price is so high! In fact, this is not the case. Because there is no spot for any processing center manufacturer, and the needs of the manufacturers who purchase the processing center are different, the processing center is also an on-demand production equipment. There is a difference in price, that is, a different configuration! ! What are the factors that affect prices?
1. Numerical control system
The numerical control system can be said to be the brain of the machining center. Any machining operation of the machining center cannot be separated from programming, and the numerical control system is also a relatively expensive part. At present, the commonly used CNC systems on the market are divided into two types, domestic and imported, and there are mainly these types.
The CNC systems of imported machining centers are commonly used FANCN, Mitsubishi, and Siemens. Imported machining center CNC system has the characteristics of stable and reliable performance, fast running speed, and strong data processing ability, which is suitable for processing more complex workpiece molds. However, the price is high, the operation interface is more complicated, and the requirements on the theoretical basis of CNC are higher.
Common CNC systems for domestic machining centers include Huazhong CNC, Kane, and Taiwan's new generation systems. The domestic CNC system has developed rapidly and has fully occupied the market. The domestic CNC system has the characteristics of friendly interface, convenient operation, and high-precision machining, and is the best choice for the pursuit of cost performance. In recent years, the domestic CNC center has been continuously developed and improved, and the five-axis linkage technology can be perfectly configured.
2. the tool magazine
The tool magazine is equally important to the machining center, and all kinds of process processing are completed by the tool magazine. Tool magazines are generally divided into three types, disc type, hat type and chain type tool magazines. Vertical machining centers use disk type and hat type relatively more. Chain type is generally used for large machine tools, so we don’t do it here. Star detailed introduction. The hat type tool magazine is cheaper than the disc type, because the tool change speed is lower than that of the disc type. The disc type uses a mechanical arm to change the tool. Thanks to the manipulator, the disc-type tool magazine can complete automatic tool change in just a few seconds. According to your machining situation, you can choose the number of tools ranging from 16/24.
The spindle unit is also an electric spindle, which determines the processing power of a machining center. The spindle speed is generally very high, all above 8000rpm/min, and the spindle speed above 10000rpm/min is a high-speed spindle. The machine tool will generate a lot of heat under high-speed processing, and the heat of high chipping will adhere to the machine tool table and workpiece. The surface will not only affect the machining accuracy of the workpiece, but also cause damage to the machine tool, so generally the spindle will be equipped with an oil-cooled or water-cooled cooling system. The most common transmission methods of spindles are belt transmission and direct transmission. Direct transmission is suitable for light cutting at high speeds, and direct transmission is generally selected for high-speed spindles.
4. the number of axes
Most of the machining centers are three-axis machining centers, and the X, Y, and Z three-axis linkage can meet most of the machining needs. However, there are also customers who add an additional rotary axis on the basis of the three-axis. Simply put, an indexing head is added on the basis of the three-axis, which becomes X, Y, Z, A or X, Y, A, B. . It can reduce benchmark conversion, improve processing accuracy, reduce the number of fixtures and floor space, shorten the production process chain, simplify production management, shorten the development cycle of new products, and the corresponding price is also much higher.
