CNC Milling is a machining process used to process prismatic parts. CNC Milling has a rotating cylindrical cutting head and milling cutters with multiple chip grooves (usually referred to as end mills or end mills), which can move along different axes and are used to machine narrow holes, grooves, outer profiles, etc.
CNC milling machine is an automatic processing equipment developed on the basis of general milling machines, controlled by digital signals from electronic meters. CNC milling machines are divided into two categories: those without tool libraries and those with tool libraries, among which CNC milling machines with tool libraries are also known as machining centers. CNC precision machining has the advantages of high precision, high efficiency, flexibility, and automation, which can achieve high-precision machining and customized production in medical equipment, aerospace, and other fields, meeting the needs of different customers.
In addition, the precision carving machine in CNC Milling is also a type of CNC machine tool, mainly used for non-contact cutting and punching of metal or non-metal sheets and pipes. The precision carving machine is one of the important equipment in CNC machining, with stable and reliable operation, good processing quality, high efficiency, simple operation and easy maintenance.
Non standard CNC milling parts have a unique position and importance in modern manufacturing industry.
characteristic:
Uniqueness: Non standard parts are usually customized according to specific needs and designs, with unique shape, size, and performance requirements.
Complexity: may involve complex geometric shapes, high precision requirements, or special material properties.
Processing difficulties:
Process planning: It is necessary to carefully design the machining process, including tool paths, cutting parameters, etc., to ensure efficient and high-quality machining.
For example, for non-standard parts with complex internal cavity structures, it is necessary to plan the forward and backward cutting methods of the tool reasonably to avoid interference and collision.
Clamping scheme: Due to its irregular shape and high difficulty in clamping, it is necessary to customize special fixtures or adopt innovative clamping methods.
For some thin-walled non-standard parts, vacuum adsorption or multi-point support clamping methods may be used.
Tool selection: It may be necessary to use unconventional tools or make special modifications to standard tools.
Solution:
Advanced CNC programming technology: using computer-aided manufacturing (CAM) software for precise programming and simulation processing.
For example, simulation can identify potential machining problems in advance and optimize them.
High precision measurement and inspection: During and after the machining process, high-precision equipment such as coordinate measuring machines are used for inspection to ensure that the parts meet the requirements.
