Engraving and milling machine
As the name implies, it can be carved or milled. On the basis of the engraving machine, the spindle and servo motor power are increased, and the bed is subjected to the force, and the spindle is also kept at a high speed. The engraving and milling machine is also developing at a high speed. It is generally called high-speed machine. It has stronger cutting ability and high processing precision. It can also directly process materials with hardness above HRC60. It can be molded once and is widely used in precision molds. , mold copper electrode, aluminum parts production, shoe mold manufacturing, fixture processing, watch industry. Due to high cost performance, fast processing speed and good smoothness of processed products, it plays an increasingly important role in the machine tool processing industry.
CNC machining center
Hong Kong and Taiwan and Guangdong are also called computer gongs. The characteristics of machining parts on the machining center are: after the parts are machined, the CNC system can control the machine to automatically select and replace tools according to different processes; automatically change the machine tool spindle. The speed, the feed rate and the movement path of the tool relative to the workpiece and other auxiliary functions continuously process the drilling, boring, reaming, boring, tapping, milling and other processes on the workpiece. Since the machining center can complete various processes in a centralized and automatic manner, it avoids artificial operation errors, reduces workpiece clamping, measurement and adjustment time of the machine tool, and workpiece turnover, handling and storage time, greatly improving machining efficiency and machining accuracy. Therefore, it has good economic benefits. The machining center can be divided into a vertical machining center and a horizontal machining center according to the position of the spindle in space.
Engraving machine
The torque is relatively small, and the high spindle speed is suitable for the machining of small tools. It focuses on the “engraving” function and is not suitable for large workpieces with strong cutting. At present, most of the products on the market with the name of the engraving machine are mainly for processing handicrafts, and the cost is low. Due to the low precision, it is not suitable for mold development; engraving and milling machine and machining center. The maximum speed of the spindle (r/min) is compared with the index data of the engraving machine: machining center 8000; the most common engraving and milling machine is 240,000, and the high speed machine is at least 30,000; the engraving machine is generally the same as the engraving and milling machine, and the engraving machine for high-light processing can reach 80,000. But that is not the general electric spindle but the air-floating spindle.
Spindle power: The processing center is the largest, from several kilowatts to tens of kilowatts; the engraving and milling machine is second, usually within ten kilowatts; the engraving machine is the smallest. Cutting capacity: The largest machining center, especially suitable for heavy cutting and thickening; the engraving and milling machine is second, suitable for finishing; the engraving machine is the smallest.
Speed: Because the engraving and milling machine and the engraving machine are relatively light, their moving speed and feed speed are faster than the machining center, especially the high speed machine with linear motor can move up to 120m/min.
Accuracy: The accuracy of the three is similar.
From the processing size:
The work area can respond better to this. The smallest workbench area (unit mm, the same below) of the domestic machining center (computer 锣) is 830*500 (850 machine); the largest workbench area of the engraving and milling machine is 700*620 (750 machine), and the smallest is 450. *450 (400 machine); engraving machine generally does not exceed 450 * 450, the common is 45 * 270 (250 machine).
From the application object:
Machining center is used to complete the processing equipment of large milling workpieces, large molds, hardness comparison materials, also suitable for the opening of ordinary molds; engraving and milling machine is used to complete small milling, small mold finishing, suitable Processing of copper, graphite, etc.; low-end engraving machine is biased towards wood, two-color board, acrylic sheet and other low-hardness sheet processing, high-end suitable for wafer, metal casing and other polishing and polishing.
It should be noted that there is no such thing as a CNC engraving.milling machine in foreign countries. Strictly speaking, carving is part of milling, so foreign countries only have the concept of machining center, and thus derive the concept of small machining center. Instead of the engraving and milling machine. Buying an engraving machine or buying a CNC milling machining center is often a question to ask yourself, depending on actual production needs. In addition, there are currently high-speed cutting machine tools (HSCMACHINE), which is called high-speed machine in China.
The difference between the three models:
CNC milling and machining center for machining workpieces with large milling operations
CNC engraving and milling machine for small milling, or soft metal processing equipment
High-speed cutting machine for processing medium milling and minimizing the amount of grinding after milling
