Basic Methods for CNC Lathe Manufacturers to Master Tool Precision
Tool accuracy has always been one of the research and development directions for CNC lathe manufacturers. It can not only reduce the technical limitations of the lathe itself but also improve the work efficiency of the lathe. Therefore, when purchasing a lathe, tool accuracy is a very important performance indicator. Today, we will share with you the basic methods of mastering tool accuracy.The improvement of the accuracy of slender rod cutting tools has always been a difficulty in tool manufacturing, mainly due to the longer effective part of such tools and the distance between the cutting edge and the clamping part during manufacturing. Due to the long distance between the cutting edge and the clamping part, as well as the certain clamping accuracy of the tool clamping chuck, the radial circular runout at the cutting edge may have reached 0.005mm~0.01mm before starting grinding. By using strong grinding technology, the grinding force is high, resulting in large elastic deformation of the tool. During the machining process, many problems may arise, such as asymmetric tool groove shape, non-compliance with the requirements for the outer circle size, edge parameters, and shape errors of the tool, In severe cases, it may even cause the tool to break.
The impact of machine tool accuracy on tool accuracy When manufacturing any tool, the accuracy of the machine tool is the key to determining tool accuracy, and slender rod shaped tools are no exception. The CNC tool grinding machine produced by an Australian company has five axes, namely the x, y, and z coordinate axes, and the a and c rotation axes, the p-axis. The accuracy of each axis is very high. The positioning accuracy of the x, y, and z coordinate axes can reach 0.001mm, and the positioning accuracy of the a and c rotation axes can reach. 001 °. The two grinding wheel axes of the machine tool are arranged longitudinally. When machining different parts of the tool, not only different grinding wheels can be selected, but also different grinding wheel axes can be selected. When the grinding wheel axis needs to be replaced, it can be automatically replaced by program control. The repeatability of the two axes is very high, which can fully meet the accuracy requirements for machining slender rod shaped tools.
The above is the basic method for mastering tool accuracy shared by CNC lathe manufacturer Haishu Machinery, hoping to be helpful for everyone in operating CNC lathes in the future.
