Our series of products represented by Milling Insert, Cnc Insert, Grooving Insert, etc. have become a model in the industry with excellent quality, and buyers from all over the world are welcome to wholesale and buy.
Factors of the cutting tool itself:
1. The material of tungsten carbide cutting tool
Tungsten carbide steel is very hard and is often used as a material for cutting tools. Tungsten carbide steel itself contains carbon, tungsten, cobalt and other alloy materials to enhance its properties.
2. Coating of cutting tools
A thin film is formed on the surface of the cutting tool by chemical or physical methods, so that the cutting tool can obtain excellent comprehensive cutting performance to meet the cutting requirements. Compared with uncoated cutting tools, coated cutting tools have obvious advantages: they can greatly increase the service life of cutting tools; effectively improve cutting efficiency; improve machining accuracy and significantly improve the surface quality of the workpiece to be machined; effectively reduce Tool material consumption. Due to the advancement of modern technology, more coating techniques have been developed for application to cutting tools. It can be used according to the material and properties of the workpiece to be machined.
3. Dimensions of cutting tools
Depending on the shape and size of the workpiece to be machined, the type and size of cutting tools required will vary. When choosing the right cutting tool, the machining application must be considered, if an inappropriate cutting tool size is selected, it may cause vibration during machining, disturbances in the machining process, cracked tip of the cutting tool, rapid wear of the cutting tool tip and cutting tool Wrapped tip.
Whether it is a test cutting tool for a new project or a cutting tool for improved development, the above three factors need to be considered. The follow-up is to keep a record of tool life in order to find the best tool condition and meet the tool life.
external factors:
1. How to tighten the screw of the cutting tool
The screws of the tightening tool are actually quite simple, but each tightening method, tightening angle and tightening force are different. Method, angle and force affect the life of the cutting tool and the stability of the machining process. In addition to the educational training operators need to attend, the situation can be improved with torque-limiting screwdrivers and torque-limiting wrenches.
2. Cutting parameters
Cutting parameters include cutting speed, feed rate and depth of cut. These parameters have a great influence on the life of the cutting tool. Among them, the cutting speed has the greatest impact. Usually, cutting tool manufacturers will provide cutting parameters for customers' reference.
3. Workpiece
Material The material of the workpiece can be divided into copper, aluminum, low carbon steel, alloy steel, tool steel, nickel-based alloy, stainless steel, etc. Each material has different properties, and the material properties of these materials in the workpiece can also affect the life of the cutting tool.
4. Tool holder
Toolholder wear can vary and is affected by each operator's habits. It is recommended to check the tool holder before changing to a new cutting tool. Because when the tool holder is worn, it will affect the stability of the machining process and also affect the life of the cutting tool.
5. The state of the machine
Because vibration will occur during processing, if the stability of the machine is not good during processing, it will affect the life of the cutting tool, and also cause the dimensional tolerance of the machined parts to be too large and the surface to be rough. Therefore, how to choose the machine is very important. Usually the machine must be maintained, with regular replacement of mechanical consumables. During installation and removal, it must be cleaned and maintained.
6. The difference between cutting fluid
In addition to improving lubricity during metalworking, cutting fluids also provide cleaning, rust prevention and cooling. Cutting fluid is essential in the field of turning. In addition to selecting the appropriate cutting fluid, it is also necessary to replace the new cutting fluid regularly before it can be used.
7. Whether to use high pressure cutting cooling system
High temperature water vapor will be generated when the workpiece is processed, and the water vapor on the surface of the workpiece will block the adhesion of the cutting fluid. The cutting fluid can directly contact the workpiece and the cutting tool tip through the pressurized cutting fluid to achieve a cooling effect. When the cutting edge is less prone to overheating, cutting parameters will be improved, and chip evacuation will also be effective during machining and prevent chip wrapping around the cutting edge.
