How to choose CNC Knife tools: the selection skills of CNC Knife tools
Factors affecting the selection of CNC Knife tools
When choosing the type and specification of the tool, the following factors are mainly considered:
(1) Nature of production
The nature of production here refers to the batch size of the parts, which mainly considers the impact on tool selection from the processing cost.
For example, it may be cost-effective to use special Knife tools in mass production, while in single or small batch production, it is more suitable to choose standard Knife tools.
(2) Machine type
The influence of the CNC machine tool used to complete the process on the selected tool type (drill, turning tool or milling tool). Under the condition that the rigidity of the workpiece system and the tool system can be guaranteed, high-productivity Knife tools, such as high-speed cutting Knife tools and large-feed Knife tools, are allowed.
(3) CNC machining plan
Different CNC machining programs can use different types of Knife tools. For example, drilling and reaming can be used for hole processing, or drilling and boring Knife tools can be used for processing.
(4) The size and shape of the workpiece
The size and shape of the workpiece also affect the selection of tool types and specifications. For example, special Knife tools must be used to process special-shaped surfaces.
(5) Machining surface roughness
The surface roughness of the machined affects the structure shape and cutting amount of the tool. For example, rough milling cutters can be used for rough milling of blanks, and fine-tooth milling cutters are best used for finishing milling.
