6 Principles for Choosing the Right Cutting Tool: A Comprehensive Guide

Since the Industrial Revolution in the 18th century, the material of the tool has been continuously improved and evolved, and the cutting speed has also increased to more than 100 times the original. We have developed #High-speedSteelTool #CarbideTool #CeramicTool #SuperhardMaterialTool, etc., but how to choose the right tool?

Now let's follow TMT Machine to see which six principles you need to know when you choose cutting tools.

1. Material of tools
   Understand the raw materials with different hardness, the type and shape of finished parts, special processing conditions and surface quality requirements, etc. Select the matching material of tools, so that the processed product can present the most perfect result.
2. Characteristics of tools
   The quality of the material will greatly affect the quality of the machined surface, efficiency and tool life.
   A suitable tool should have:
   - High hardness and wear resistance, and resistance to blade wear and deformation.
   - Good chemical stability, with anti-oxidation and anti-diffusion wear properties.
   - Sufficient strength and toughness, and resistance to overall fracture.
   - High heat resistance, low friction coefficient.
3. Cutting performance
   The main factors that affect the cutting performance are the #material and #processing parameters of the workpiece.
   The hardness of tool must be higher than workpiece to cut a beautiful finish and shorten machining time.
   The setting of machining parameters such as cutting speed, feed, depth of cut and lubricating oil will also affect the cutting performance and wearing degree of the tool.
4. Confirm the purpose of processing
   According to the processing conditions or different cutting requirements such as roughing, finishing, and semi-finishing, select the appropriate tool.
   For example, for fine milling, the sharpness of the edge is the priority; while for rough milling, the priority is to be strong and wear-resistant.
5. Cost-effectiveness of tools
   Choosing cost-effective tools can reduce production costs and improve product competitiveness. The owner can use the service life of the tool, the degree of wear and tear, the difficulty of regrinding, the chip tolerance and chip removal rate, strength and stiffness as the judgment indicators.
6. Cutting method
   Turning / Drilling / Planning / Broaching / Grinding / Milling
   Multiple cutting methods can complete various types of geometric shapes. Before processing, choose a proper processing method before selecting a suitable tool.

Following the above six principles, you can easily select the correct tool to achieve the purpose of improving processing efficiency and reducing costs!

Before using the tool, it is also necessary to ensure that the surface of the tool is bright and defect-free. If the tool is found to be damaged or defective, it should be solved or replaced immediately to avoid the breakage of the tool or the poor finish during the subsequent processing, resulting in product defects.
