How To Choose A CNC machine Tool

Since the spindle speed and range of to CNC machineols are much higher than those of ordinary machine tools, and the output power of the spindle is also large, compared with the previous processing methods, the requirements for high precision, high strength, high rigidity, high durability, high durability , dimensional stability, easy set-up and adjustment of CNC machining tools put forward higher requirements. This requires proper tool construction, standardization and concatenation of geometric parameters. The machining tool of CNC Machining is one of the prerequisites for improving machining efficiency, and its selection depends on the shape of the object to be machined, the state of the material, the rigidity of the fixture, and the tool selected by the machine tool.

Please consider the following:

1. Select the tool according to the cutting performance of the steel machining parts and materials that do not pass.

For rotating or grinding high-strength steel, titanium alloy and stainless steel components, indexable carbide tools with better wear resistance are recommended.

2. Select the tool according to the part processing stage.

That is to say, in the roughing stage, the rigidity is mainly reduced by removing the finishing, the purpose is to select a more precise tool, in the semi-finishing process, the machining accuracy and product quality of the parts are mainly ensured, but higher performance and The durability of high-precision tools, the tools used in the roughing stage are less accurate. In addition, the tools used in the finishing table are very precise.

If the same tool is selected for roughing and finishing, most of the tool edge removed from finishing will wear slightly and also due to coating wear, so it is recommended to select the tool that is removed from finishing during roughing . Continued use can affect finishing. Machining quality, but little effect on rough surface finish.

3. Select the tool and geometric parameters according to the characteristics of the processing area.

If the structure of the part is acceptable, tools with large diameters and small aspect ratios must choose the edge of an over-center milling cutter for cutting thin-walled and ultra-thin pendulum parts, and must have sufficient centripetal angle to lower the tool and The cutting force of the cutting part. In machining parts of soft materials such as aluminum or copper, choose an end mill with a slightly larger angle, no more than 4 teeth.
