When choosing the type and specification of the cutting tool, the following factors should be considered:

1. Nature of production


Here the production nature refers to the batch size of parts, mainly from the processing cost to consider the impact of cutting tool selection. For example, it may be cost-effective to use special cutters for mass production, whereas standard cutters are more suitable for single or small batch production.

2. Machine tool type


The influence of the CNC machine used to complete the process on the type of tool chosen (drilling, turning, or milling). High productivity tools, such as high speed cutting tool and high feed tools, are allowed when the rigidity of the workpiece system and tool system is maintained.

3. NC machining scheme


Different nc machining schemes can use different types of tools. For example, the processing of the hole can be used to drill and reaming drill, can also be used to drill and boring knife for processing.

4. the size and shape of the workpiece


The size and shape of the workpiece also affect the choice of tool type and specification, such as special surface to use special tools to process.

5.Machining surface roughness


Machining surface roughness affects the structure of the tool shape and cutting dosage, such as rough milling, rough tooth milling cutter can be used, fine milling is best with fine tooth milling cutter.

6. Machining accuracy


Machining accuracy affects the type of finishing tool and structure shape, such as the final machining of the hole according to the accuracy of the hole can be used to drill, reaming drill, reamer or boring knife to process.

7.Workpiece material


Workpiece material will determine the choice of cutting tool material and cutting part of the geometric parameters, tool material and workpiece machining accuracy, material hardness and so on.
