At present, the development level of machine tool accessories in my country still needs to be improved, and efforts should be made to achieve integration with international standards, so that my country's turning and milling compound machine tool industry can achieve more rapid and sustainable development. In recent years, my country's CNC turning and milling compound machine tools have shown a rapid development trend, and production and sales have Also rising. With the continuous development and improvement of CNC technology, the requirements and dependence of machine tool mainframes on accessories are getting higher and higher. And based on specific analysis, we should all know that the technological development of accessories indirectly determines the development level of machine tool mainframes. From this we can see that the development direction of specialization has become the overall development trend of my country's machine tool accessories industry.

So how can we narrow the gap with foreign industrial powers? This requires the full cooperation of my country's major machine tool factories. The companies themselves must speed up the pace of technological reform, actively innovate independently, and have the courage to learn more from foreign companies. Companies should strive to learn internationally advanced machine tool technology and carry out innovation work in an all-round way. Corporate executives Innovation in machine tool accessories should also be encouraged and strongly supported, so that my country's machine tool accessories industry will become stronger and stronger.

Due to the steady growth of my country's economy, my country's CNC turning and milling composite machine tool accessories industry will also show a stable development trend, and its market share will continue to increase. This driving role has enabled my country's machine tool industry to continue to develop, but there are also problems in my country's machine tool accessories industry. There are certain shortcomings, but of course there is also good room for development.

Disadvantages: The development of turning and milling compound machine tool accessories must be driven by the overall development of the machine tool industry. This has to mention the development prospects of my country's machine tool industry. If my country's CNC turning and milling compound machine tool industry wants to develop more stably and Rapid development requires comprehensive numerical control reform and innovation, so that a series of machine tool accessories industries can continue to follow up and advance together.

However, the funds of most turn-milling compound machine tool parts factories in my country are still relatively tight, which has had a great impact on technological innovation and reform. This is also an important reason why the level of parts in my country has not improved rapidly. It has become an obstacle affecting the development of CNC turning and milling compound machine tool industry. Compared with international technology, domestic machine tool accessories still have a certain gap with developed countries in terms of technology, quality or performance.

In order to extend the service life of the machine tool, confirm the normal operation of the various functions of the machine tool, and ensure the accuracy of the machine tool, it is necessary to do a good job in daily maintenance of the machine tool, and conduct regular confirmation and inspection. Let’s share the frequency and method of machine tool maintenance.

1. Daily inspection: The main items include hydraulic system, spindle lubrication system, guide rail lubrication system, cooling system, and pneumatic system. The daily inspection is based on the normal conditions of the system. For example, when performing process inspection of the spindle lubrication system, the power light is on and the oil pressure pump should be running normally. If the power light is not on, the spindle should be kept stopped and communicate with the machinist. Contact us for repairs.

2. Weekly inspection: Its main items include machine tool parts and spindle lubrication system, which should be correctly inspected every week. In particular, iron filings should be removed from machine tool parts and external debris should be cleaned.

3. Monthly inspection: mainly inspect the power supply and air dryer. Under normal circumstances, the power supply voltage has a rated voltage of 180v~220v and a frequency of 50hz. If there is any abnormality, it must be measured and adjusted. The air dryer should be disassembled, cleaned and assembled once a month.

4. Quarterly inspection: Mainly inspect the machine tool bed, hydraulic system, and spindle lubrication system. For example, when inspecting the machine tool bed, it mainly depends on whether the accuracy and level of the machine tool meet the requirements in the manual. If there are any problems, you should contact the machinist immediately. When checking the hydraulic system and spindle lubrication system, if there are any problems, replace them with new oil and clean them respectively.

5. Semi-annual inspection: After half a year, the hydraulic system, spindle lubrication system and X-axis of the machine tool should be inspected. If any problems occur, new oil should be replaced and cleaned.

The inclined bed CNC lathe adopts an inclined structure, and the bed is a hollow structure, which greatly improves the bending and torsional rigidity of the machine tool during operation, and at the same time has high stability. The high rigidity and high stability of the inclined bed CNC lathe provide a strong guarantee for the high precision of machine tool processing.

Inclined bed CNC lathes are mainly used for processing complex rotating parts. It can meet the processing of internal and external circles, step surfaces, cones, spherical surfaces, grooves, threads and complex curved surfaces. It can satisfy the rough and finishing machining of copper, aluminum, iron, stainless steel and other casting and forging blanks.

The inclined bed CNC lathe has good reliability, strong rigidity, high precision, long life and high speed. It can reliably and stably complete the rough, fine and finishing processing of various difficult-to-machine materials. The rotary tower knife is used, which has high positioning accuracy and small deformation during heavy cutting.

The impact of cutting processing on workpiece quality includes surface decarburization, residual stress, machining allowance, surface smoothness, removal of carbon-poor layer, etc. This is when the workpiece is in the tempering, normalizing, and annealed state, and the hardness is lower than 45HRC. However, the effect is not significant and will not constitute a change in the potential function of the workpiece.

Hard machining refers to the processing of hardened steel or workpieces. The higher hardness of 50-65HRC, materials such as bearing steel, high-speed steel, roll steel, general quenched steel and quenched mold steel, has a significant impact on the cutting process. . The factors that cause a certain degree of damage to the surface of the processed workpiece mainly include cutting heat generation and conduction, high-speed friction and wear during the cutting process. The integrity of the surface processed by hard cutting mainly includes the surface structure and its thickness, surface roughness, dimensional accuracy, distribution of residual stress and white layer generation.

The surface hardness of the processed workpiece increases with the decrease of feed amount and cutting amount, and increases with the increase of cutting speed. The higher the hardness of the machined workpiece surface, the greater the depth of the hardened layer. The surface of the workpiece after hard cutting is full of residual compressive stress, while the compressive stress of the workpiece after grinding is mainly concentrated on the surface of the workpiece.

The factor that affects the surface integrity of the workpiece is the hardness of the workpiece. The greater the hardness value of the workpiece, the more beneficial it is to the formation of residual compressive stress. The larger the obtuse radius of the tool used in cutting processing, the greater the value of residual compressive stress; the higher the hardness of the workpiece, the greater the value of residual compressive stress.

The formation of the white layer is another important factor affecting the quality of the surface of the workpiece processed by hard cutting. A kind of tissue structure formed along with the hard cutting process is the white layer. The white layer has common grinding characteristics, namely high hardness, good corrosion resistance and high brittleness. Higher brittleness can easily cause early shedding failure, or even cause the workpiece to crack after being left for a period of time after processing.
