Rectangular Broaches Manufacturer

Rectangular broaches are the most popular form of broach. This is because rectangular broaches give more precision when cutting objects with complicated contours.

Advantages Of Rectangular Broaches

High processing efficiency: Rectangular broaching can remove a large amount of material in one stroke, which greatly improves production efficiency and is especially suitable for mass production.
High processing accuracy: high dimensional accuracy and shape accuracy can be obtained. The rectangular surface roughness after broaching is low, and the dimensional tolerance can be controlled within a small range.
Suitable for a variety of materials: can process various metal materials, such as steel, cast iron, non-ferrous metals, etc.
Long tool life: Rectangular broaches are usually made of high-strength materials and have good wear resistance. With reasonable use and maintenance, the tool life is long.

Manufacturing Process Of Rectangular Broaches

1. Material selection

Materials with high hardness, high wear resistance and good toughness such as high-speed steel and cemented carbide are usually used.

2. Blank preparation

Forging, rolling and other methods are used to prepare broach blanks to improve the internal structure of the material and improve the performance of the material.

3. Mechanical processing

Turning, milling, grinding and other processing methods are used to process various parts of the broach, such as the handle, neck, transition cone, teeth, etc.

4. Heat treatment

Perform heat treatment such as quenching and tempering on the broach to improve the hardness, strength and wear resistance of the broach.

5. Surface treatment

In order to improve the wear resistance, corrosion resistance and cutting performance of the broach, the broach can be surface-coated, such as coating with hard coatings such as TiN and TiAlN.

6. Quality inspection

Strictly inspect the dimensional accuracy, shape accuracy, hardness, surface quality, etc. of the broach to ensure that the broach meets the design requirements.
