How To Reduce The Tool Radial Runout In CNC Milling?

In the CNC cutting process, there are many reasons for machining errors. The error caused by the tool radial runout is one of the important factors, which directly affects the minimum shape error and the machined surface geometry accuracy. In actual cutting, the radial runout of the tool affects the machining accuracy, surface roughness, uneven wear of the tool, and the cutting process characteristics of the multi-tooth tool. The greater the radial runout of the tool, the more unstable the machining state of the tool, and the more obvious the impact. Causes of radial runout Tool manufacturing errors and clamping errors cause drift and eccentricity between the tool axis and the ideal rotation axis of the spindle, as well as specific processing techniques and tooling, which may cause radial runout of CNC milling machine tools during processing. The influence of the radial runout of the spindle itself The main reasons for the radial runout error of the main shaft are the coaxiality error of each journal of the main shaft, various errors of the bearing itself, the coaxiality error between the bearings, and the deflection of the main shaft. Their influence on the radial rotation accuracy of the spindle varies with the processing method. These factors are formed in the process of manufacturing and assembling the machine tool, and it is difficult for the operator of the machine tool to avoid their influence. The impact of the inconsistency between the tool center and the spindle rotation center When the tool is installed on

Can titanium be CNC machined?

Can titanium be CNC machined? At present, many Machininery manufacturers have launched high-efficiency high-speed CNC machine tools for HEM-HSM cutting of large aluminum alloys CNC Machining and other light alloy materials. It is obviously inappropriate to realize HEM-HSM machining with difficulty to machine metal materials with high strength and high hardness like Titanium. Although it can also cut these hard alloy materials, its cutting efficiency is often unacceptable. The main reasons are: (1) As mentioned above, the machining of hard alloy materials such as titanium alloys requires large cutting force, or high torque spindles, and high-efficiency high-speed CNC machine tool spindles are typically used for HEM-HSM cutting of light alloy materials such as aluminum alloys. Most of the torque is less than 100Nm, generally not more than 200Nm, and it does not have the cutting ability for high-efficiency machining of hard alloy materials such as titanium alloys. (2) As mentioned above, the processing of titanium alloys and other hard alloy materials is usually only allowed to use lower cutting speeds, that is, only lower spindle speeds can be used, and the HEM-HSM cutting processing of light alloy materials such as aluminum alloys is typically used. The spindle speed range of high-efficiency high-speed CNC machine tools is not compatible with the requirements of the current titanium alloy processing technology. Therefore, it needs to special design and manufacture of many key CNC components such as the structure, rigidity, dynamic characteristics, spindle and coordinate drive, cooling system, tool interface, and control system of

We are using advanced technology and equipment to offer high precision for producing metal and plastic machining parts. In this article, we focus on some common problems and solutions of aluminum alloy parts processed by CNC wire cutting. When machining aluminum alloy parts by CNC wire cutting, there are often problems such as serious wear of the feed block, short circuit, wire breakage, processing track distortion, and workpiece deformation, and some directly cause the processed product to be scrapped.  The problem of wire-cutting aluminum alloy parts easy to break The reason why wire-cut aluminum alloy parts are easy to break When wire cutting aluminum alloy parts, because the material is relatively soft, chip removal is difficult, and aluminum alloy is very easy to form a hard oxide film at high temperatures. A large amount of aluminum oxide or aluminum scraps is easy to stick to the molybdenum wire, making the molybdenum wire and the feed block Deep grooves will soon be ground at the contact area. Soft aluminum and hard abrasive grains are mixed together and stuffed in the groove. Once brought in, the groove will be squeezed to death, and the wire will be jammed. Solution In view of the problem that the molybdenum wire is caught in the feed block and the molybdenum wire is
