Gear machining tool selection is particularly important

Gear machining tool selection is particularly important, because tool wear, tool collapse, etc. will seriously affect production efficiency and increase production costs.

XNUMX. Gear cutter:

forGear processingTo produce special tools, the tools used in different processing methods are different.

Common gear cutters include hobbing cutters for gear hobbing machines, gear shaping cutters for gear shaping, milling cutters for gear milling, gear shaving cutters for shaving gears, broaches, bevel gear cutters, chamfering cutters and other tools, etc.

According to the processing objects, gear cutters can be divided into:

There are two types of cylindrical gear processing tools and bevel gear processing tools.The former can be divided into forming gear cutters and generating gear cutters according to different processing principles.

According to the material used in the tool, it can be divided into:

Coated carbide tools, ceramic tools and CBN tools.

XNUMX. Gear tool application:

1. Gear hob:

Used for the most efficient and widely used straight teeth andhelical gearRough machining and precision machining.

2. Shaving knife:

Mainly used for finishing the shape of heat-treated anterior teeth. 

3. Gear shaper:

Used for processing double gears, multiple gears, internal gears and herringbone gears that cannot be processed by gear hobs. 

4. Gear broach:

It is often used to process internal gears in mass production.

5. Disc gear milling cutter:

It is used to process straight or helical cylindrical gears in single-piece, small batch or repair production.

6. Finger gear milling cutter:

Used for processing large-modulus spur gears, helical gears and herringbone gears.

XNUMX. Gear tool selection:

1. There are two major types of gear processing methods, namely the generation method and the forming method. The tools used are different.

2. Commonly used knives for generating method processing include hobs, gear shapers, comb knives and shaving knives.

3. The forming method will use gear broach, disc gear milling cutter, disc gear milling cutter and gear shaper cutter head.

4. The machining accuracy and productivity of generated gear tools are also high, so they are widely used in production.

5. The selection of tools will generally be based ongearChoose different tools for different materials, workpiece size, workpiece processing accuracy requirements, molding methods, processing methods, processing equipment, heat treatment conditions, etc.

6. After heat treatment, large gears not only have high hardness, but also have large deformation, which has high requirements for the wear resistance and impact toughness of the tool.
