The most important point to improve the processing speed of CNC engraving and milling machine is to determine a reasonable engraving speed according to the hardness of engraving materials and the performance of CNC engraving and milling machine tools. Of course, the stability of CNC engraving and milling machine itself should also be considered, so that the machine can not be overloaded.
When using CNC engraving and milling machine for processing, try not to use the maximum tool feed to process, every kind of material tool will have a maximum tool feed. Because this value is only a reference value for users, it can not exceed this value, so in the actual operation, it should be less than this value as far as possible, and it is very ideal to control it at two-thirds of the value. In this way, the tool can be used for a long time, and the tool life will be longer.
In addition, CNC engraving and milling machine processing will be divided into rough machining and finishing two parts, the first part of the overall speed of rough machining and tool selection should be faster, better, as far as possible to cut all the margin, in order to save time and improve work efficiency, finishing is to adjust the speed of CNC engraving and milling machine properly, to ensure the precision of product processing.
1、 The mechanical performance is stable and reliable, and the structure is limited
The bed, column and other basic parts used are heavy and solid casting components, rather than those welded components. After the transformation, the machine tool has high performance and good quality, and can be used as new equipment for many years.
2、 The latest control technology can be adopted:
According to the development speed of technological innovation, the automation level and efficiency of production equipment can be improved in time, and the quality and grade of equipment can be improved.
3、 Familiar with the equipment, easy to operate and maintain
When purchasing new equipment, we don’t know whether the new equipment can meet the processing requirements. Otherwise, the machining capacity of the machine tool can be calculated accurately.
4、 We can make full use of the existing conditions
It can make full use of the existing foundation and does not need to rebuild the foundation as when purchasing new equipment.
5、 Reduce investment and short delivery time:
In some special cases, the manufacturing and installation of CNC machine tools, such as high-speed spindle and tray automatic exchange device, are too labor-consuming and expensive, and the transformation cost is often increased by about three times. Compared with the purchase of new machine tools, it can only save about 50% of the investment.
CNC milling machine, as the name suggests, is an upgraded version of milling machine, which is developed on the basis of conventional milling machine. The processing skills of the two are basically the same, and the structure is also somewhat similar. The difference is that the CNC milling machine is an automatic machine tool which uses the computer program as the guide, so its structure is also very different from the usual milling machine.
Starting NC milling machine is usually composed of NC system, main drive system, feed servo system, cooling smooth system, etc
- The spindle box includes the spindle box and the spindle drive system, which is used for clamping the tool and driving the tool to rotate. The spindle speed scale and output torque have a direct impact on the processing.
- The feed servo system is composed of feed motor and feed performing mechanism. According to the feed speed set by the program, the relative motion between the tool and the workpiece is completed, including linear feed motion and rotary motion.
- The control system is the middle of the motion control of CNC milling machine, which performs the CNC processing program to control the machine tool for processing.
- Auxiliary equipment such as hydraulic, pneumatic, smooth, cooling system and chip removal, protection equipment.
- The basic parts of machine tool usually refer to the base, column, beam, etc., which are the foundation and structure of the whole machine tool.
According to the part shape, scale, accuracy and surface roughness and other skills requirements, the processing skills are determined, and the processing parameters are selected. After technical programming or active programming with CAM software, the programmed processing program is input to the controller. After processing the program, the controller sends the command to the servo equipment. The servo equipment announces the control signal to the servo motor. The spindle motor makes the tool rotate, and the servo motors in X, y and Z directions control the tool and the workpiece to move relative to each other according to a certain track, and then complete the cutting of the workpiece.
