CNC computer gong processing needs to be proficient in horizontal processing, and large gantry (moving beam, top beam) processing. Must have good fixture foundation and measurement technology level. The difficulty of fixture analysis is that it can only be qualitative and difficult to quantify. The operation also pays attention to the handle.
In the CNC computer gongs processing process, there is a method called thread milling method, which specifically refers to it? Thread milling is to use thread milling tool, machining center three axis linkage, namely x, Y axis arc interpolation, Z axis linear feed milling method.
Thread milling is mainly used for machining large hole thread and thread hole of difficult to machine material. It has the following characteristics:
(1) high speed, high efficiency and high precision. The material is generally cemented carbide material, and the cutting speed is fast. The manufacturing precision of cutting tool is high, so the precision of thread milling is high.
(2) milling tools are widely used. As long as the pitch is the same, whether it is * * thread or right-hand thread, one tool can be used, which is conducive to reducing the cost of the tool.
(3) milling is easy to chip removal and cooling. Compared with the tap, the cutting condition is better. It is especially suitable for the thread processing of difficult to machine materials such as aluminum, copper, stainless steel, etc., especially for the thread processing of large parts and components of valuable materials, which can ensure the quality of thread processing and the safety of the workpiece.
(4) because there is no tool front-end guide, it is suitable for machining blind holes with short thread bottom holes and holes without undercut groove
