The accuracy of CNC machine tools is a very important point for machine tools, and there are many factors that can affect the accuracy of the machine tool. People working in the CNC industry may have some questions, does temperature have an impact on the accuracy of precision CNC machining center machine tools? Temperature is actually one of the factors that affect the accuracy of machine tools in precision CNC machining centers, which we can call thermal deformation. The machine tool is affected by changes in the workshop ambient temperature, motor heating, mechanical motion friction heating, cutting heat and cooling medium, which will lead to uneven temperature rise in each part of the machine tool, resulting in changes in the morphological accuracy and processing accuracy of the machine tool. We can give a simple example. A 70mm×1650mm screw is processed on a CNC milling machine with ordinary precision. The milled workpieces are compared with the workpieces processed from 2:00-3:30 pm. The cumulative error changes up to 85m. Under constant temperature conditions, the error can be reduced to 4 Read More

CNC precision machining mainly includes fine turning, fine boring, fine milling, fine grinding and grinding processes: (1) fine turning and fine boring: Most precision light alloy (aluminum or magnesium alloys, etc.) parts in aircraft use this. These methods of processing are generally used for natural single crystal diamond tools, with the arc radius of the blade less than 0.1 micron. Processing on high-precision lathes can obtain 1 micron accuracy and surface unevenness with an average height difference of less than 0.2 micron, and the coordinate accuracy can reach ±2 Microns. (2) Fine milling: used to process aluminum or beryllium alloy structural parts with complex shapes. Relying on the accuracy of the guide rail and spindle of the machine tool to obtain high mutual position accuracy. High-speed milling can be obtained by using carefully grinding diamond cutter heads for high-speed milling Accurate mirror. (3) Fine grinding: used to process shaft or hole parts. Most of these parts are hardened steel and have high hardness. Most high-precision grinder spindles use static or dynamic liquid bearings to ensure high stability. Extreme accuracy of grinding Read More

Slow-wire processing machine tools are divided into four levels: top-level, advanced, mid-range, and entry-level. 1. The machining accuracy of top-level slow wire machining machine tools can ensure that the machining accuracy is within ±0.002 mm, the high machining rate can reach 400~500 mm2/min, the surface roughness can reach Ra0.05μm, and it has satisfactory processing surface quality. , the surface has no deformed layer, and it can use φ0.02 mm electrode wire to stop micro-finishing. Most of the hosts have a thermal equalization system, and some machine tools are used to stop cutting and processing in oil. This type of machine tool is fully used, has a high level of automation, and can directly complete the precision processing of the mold. The mold life of the processed mold has reached the level of mechanical grinding. 2. Advanced slow wire-travel machining machine tools, such as machine tools, have active wire-threading, no resistance-resistant electrolytic power supply, and an overall thermal stability system. It can use φ0.07 mm to stop cutting, with an accuracy of about ±0.003 mm, and high processing The rate can reach 300mm2/m Read More

CNC machining Before formulating part machining process procedures, the types of blanks before parts processing and their different manufacturing methods must be selected. Since the number of processes, material consumption, processing labor, etc. of CNC machining parts are largely related to the selection of blanks, the correct choice of blanks has great technical and economic significance. Commonly used CNC machining parts blanks include: castings, forgings, moldings, welded parts, stamping parts, etc., and the same type of blanks may have different manufacturing methods. The choice of blanks should consider the size of the production scale, which largely determines the economics of adopting some method of blank manufacturing. If the production scale is large, high-precision and high-productivity blank manufacturing methods can be used. In this way, although the investment is high at one time, the cost of sharing it equally to each blank will be less. Moreover, since the productivity of the blank manufacturing method with higher accuracy is generally higher, it can save raw materials and significantly reduce mechanical processing labor. Read More

CNC machining of aluminum alloy has great advantages over manual processing, such as CNC machining produced aluminum alloy parts are very accurate and repeatable; CNC machining of aluminum alloy can produce parts with complex shapes that cannot be completed by manual processing. So how much do you know about the operating principles of aluminum alloy CNC processing? Let’s learn together. 1. The use environment of CNC equipment. In order to improve the service life of CNC equipment, it is generally necessary to avoid direct sunlight and other thermal radiation, and to avoid places that are too humid, too much dust or corrosive gases. Precision CNC equipment should be kept away from equipment with high vibration, such as punching machines, forging equipment, etc. CNC precision machining 2. Good power supply guarantee. In order to avoid the influence of large power fluctuations (greater than ±10%) and possible instantaneous interference signals, mechanical processing CNC equipment generally uses dedicated line power supply (such as separate from the low-voltage distribution room for use in CNC machine tools) or additional voltage stabilization devices are installed Read More

In CNC machining, after selecting a tool, many people usually don’t know how much cutting speed and speed you should choose. They just passed the experiment and as long as there were no special problems, they thought it was OK. This is very dangerous. The problem that often occurs is breaking the tool, or causing the material to melt or burn. Whether there is a scientific calculation method, the answer is yes. 1Milling SpeedMilling speed refers to the instantaneous speed of the selected point on the tool relative to the corresponding point of the workpiece. Vc=πDN/1000VC cutting speed (M/min)N Tool speed (R/min)D Tool diameter (mm) Cutting speed is affected by tool material, workpiece material, part stiffness and cutting fluid. Generally speaking, lower cutting speeds are usually used to process hard or tough metals, which are powered cutting to reduce tool wear and extend tool life. For better surface quality, soft materials are usually processed with higher cutting speeds. Read More
