What is the precision machining cnc mold processing accuracy related to? Which aspects?
In the process of processing molds, machining centers have higher and higher requirements for precision and surface processing quality. In order to ensure the quality of mold processing, we should start from the selection of machine tools, selection of tool handles, selection of tools, processing plans, program generation, and operation. Take into account the requirements of the applicant.
2. Adopt suitable handle structure
The use of high-speed and high-precision machining centers will also drive the update of related process equipment. In particular, the impact of cutting tools on the quality of CNC machining and tool handles will become prominent. In the rotary tool processing system, the collet and the machine tool
( or combinations thereof )
The tight connection can ensure the realization of tool processing performance. Generally, there are two types of interfaces between machine tools and tool holders that are frequently used: HSK hollow tool holders and BT tool holders. The taper of the taper shank interface between the machine tool spindle and the BT tool holder is
24:7, the traditional low-speed processing is suitable for using this tool holder connection method, because BT
The tool holder and the spindle of the machine tool are only matched by the conical surface. Under the action of high-speed centrifugal force, the matching clearance of the conical surface will increase, thereby affecting the quality of CNC machining. Generally, when the spindle speed exceeds 16000 rpm /
In other words, we will need to use HSK hollow shank, and the positioning structure of HSK tool bar is over-positioning, which provides a standard connection with the machine tool. Under the tension of the machine tool, the short taper and end face of the tool bar are closely matched with the machine tool.

3. Choose the right tool for processing
The rational use and selection of cutting tools will be an important factor affecting the quality of CNC machining. Cemented carbide tools are being used more and more widely. Coated carbide will replace most of the sharp steel tools in high-speed machining, including simple tools such as reamers, ball-end knives, and boring tools. Coated carbide will be used in high-speed machining. It plays an important role in processing tool materials and is applied to most conventional processing fields.
