Product performance and features

1). Do not need to make punching head, pole and frock clamp, to reduce the auxiliary cost.

2). Just only one time lathe operating, reduce process and processing time.

3). RBT-CX Special Form Rotary Broaches with stable quality, high efficiency and strong universality.

4). Using RBT-CX Special Form Rotary Broaches, the inner quadrangle, or inner hexagon, or other polygonal inner holes can be easily processed according to user needs. For processing on inner hexagon with diameter of 10mm and depth of 15mm, it just takes 30 seconds.

5). It is used for processing workpiece with hardness HRC30 or less

 

How to use?

Some notes in use

1). Choose the right model of Rotary Broaches, and attached it on the tail seat or spindle of the driving machine.

2). In order to ensure the machining precision, the Rotary Broaches must be aligned with the axis center of workpiece.

3). For using Rotary Broaches, there are two options: No.1, Rotary Broaches rotating; No.2, workpiece rotating on the driving machine.

4). In order to extend the service life of Rotary Broaches, please use the coolant or cutting oil during processing.

 

② Confirm the size of processed hole before broaching

1). Drilling diameter should be bigger than or equal to the size of the opposite edge (or the inner circle) of the blade.

2). The hole lip should be chamfered with 90 degrees, and diameter of hole lip is chamfered that should be bigger than the distance of the opposite edge of the blade, then it can guide well.

3). Drilling depth H2 should be bigger than or equal to 1.5 times of effective broaching depth (H).

 

③ Recommended processing parameters

1). Rotate speed: 300-2000 RPM, Rotary Broaches with special feature, so it allows to be used in high speed, but for there are some attentions (Machining Center): The speed should be slow or static during the Rotary Broaches comes into contact with the workpiece, until broaching head and workpiece speed keep consistent, then increase the speed.

2). Feed rate: 0.02-0.1mm/r, for copper or aluminum workpiece, the feed rate ‘f’ can be increased to 2-3 times.

3). Broaching depth: Small than or equal to 1.5 time of the distance of the opposite edge of the blade.

 

Custom Form Rotary Broaching Heads

Common forms include hex broach, square, rectangle, torx, serrations, spline, involute spline, missint teeth, double d, double hexagon, double square, keyways, rectangle and triangle. Broach Sharpening,  an external or internal broach tool can usually be sharpened one or two times if the tools are in reasonable condition.

Common forms include hex broach, square, rectangle, torx, serrations, spline, involute spline, missint teeth, double d, double hexagon, double square, keyways, rectangle and triangle.

Rotary Broaching has been one method used to obtain these various shapes. Common forms include hex broach, square, rectangle, torx, serrations, spline, involute spline, missint teeth, double d, double hexagon, double square, keyways, rectangle and triangle. Broach Sharpening,  an external or internal broach tool can usually be sharpened one or two times if the tools are in reasonable condition.  Only the front face will be re-sharpened with a cutting angle from 4 to 8°. The entire operation can be completed in a few seconds and can be generated to 0.0005 accuracy or better. Used for years on automatic lathes, Rotary Broaching has become the method of choice on Swiss Type machines, Mill, CNC lathes and Machining Centers because it eliminates a secondary operation.

RBT is happy to provide various specifications of Rotary Broaches. We offer fast customization and special order service to our customers.
