What is Broaching?
Broaching is used when precision machining is required, especially for odd shapes. Commonly machined surfaces include circular and non-circular holes, splines, keyways and flat surfaces. Typical work pieces include small to medium sized castings, forgings, screw machine parts and stampings.
Even though broaches can be expensive, broaching is usually favoured over other processes when used for high-quantity production runs. Scroll below to find out more on how the broaching process works.
How does broaching work?
- Select broach, guide and shims (of the same style) to suit bore and keyway.
Insert guide in bore and ensure there is clearance for the broach to pass through the base slot on the press. - Place the broach in the guide slot. Ensure it is square in the component and that the first cutting tooth is in contact.
- Apply the cutting oil. Push the broach smoothly through the component. If the tail of the broach is not long enough to push the last tooth through, use an extension shank.
- Insert an appropriate shim into the guide slot for multi-pass broaches.
Insert the broach into the guide slot and repeat steps 3, 4 and 5 until the keyway depth is produced.
Regrinding and Sharpening
As part of a continual maintenance programme, WDS offers an ongoing sharpening and regrinding service for customers who have previously purchased our broaches.
For maximum tool life, correct care and regrind procedures are very important. To ensure maximum quality of our broach regrinds, all broach tools received are examined by our Inspection Department and followed up with a report detailing any damage and the work required. Once the regrind work is complete, the tool is examined further to ensure all damage has been eradicated and the original integrity has been restored.
Simply call us on 0333 0435 443 for more information on sharpening and regrinding.
