Knife Classification

Cutting tools can be divided into five categories according to the shape of the workpiece surface:

Tools for machining various outer surfaces include lathe tools, planing tools, milling cutters, external surface broaches, and files; hole machining tools include drills, reamers, boring tools, reamers, and internal surface broaches;

 

Thread machining tools include taps, dies, self-opening thread cutting heads, thread turning tools, and thread milling cutters; gear machining tools include hobs, gear shapers, gear shaving cutters, bevel gears, and broaches;

 

Cutting tools include inserted-tooth circular saw blades, band saws, hacksaws, parting-off tools, and saw milling cutters.

 

In addition, there are combination tools. According to the cutting motion method and the corresponding blade shape, cutting tools can also be divided into three categories:

 

General-purpose tools such as lathe tools, planing tools, milling cutters (excluding shaped lathe tools, shaped planing tools, and shaped milling cutters), boring tools, drills, reamers, reamers, and saws;

 

Forming tools The blades of these tools have the same or similar shape as the cross-section of the workpiece being machined, such as shaped lathe tools, shaped planing tools, shaped milling cutters, broaches, cone reamers, and various thread machining tools;

 

Special tools for machining special workpieces, such as: tools used for gears, splines, etc. such as gear shapers, gear shaving cutters, bevel gear planing tools, and bevel gear milling discs.

Cutting tool material selection

The material used to manufacture knives must possess high hot hardness and wear resistance, necessary bending strength, impact toughness and chemical inertness, good processability (cutting, forging and heat treatment, etc.), and not be easily deformed. Usually, when the material hardness is high, the wear resistance is also high; when the bending strength is high, the impact toughness is also high.

Thread processing method

Thread processing is a process that uses tools to create threads. It employs cutting, turning, milling, grinding, and other processes to machine workpieces. It generally refers to the method of machining threads on workpieces using forming tools or abrasives. Main methods include turning, milling, tapping, die threading, grinding, polishing, and whirl cutting. When turning, milling, or grinding threads, the machine's transmission chain ensures that the cutting tool, milling cutter, or grinding wheel moves accurately and evenly along the workpiece's axial direction by one lead for each revolution of the workpiece.

Turning tools are among the most widely used cutting tools in machining.

Turning tools are one of the most widely used tools in cutting machining. The working part of a turning tool is the part that generates and processes chips, including the cutting edge, the structure that breaks or curls the chips, the space for chip disposal or storage, and the channels for cutting fluid.
