Rotary Broaching Holders and Broaches

Since, as the name implies, broaching can be performed on a part that is rotating, turned parts requiring a broached hole can very often be completed in the original setup on the screw machine or CNC turning machine. This eliminates the need for secondary operations and improves part uniformity.

The rotary broaching principle can also be applied to broaching on a CNC machining center or vertical mill. The only difference being that the broach holder is rotated in the machine spindle and the part is stationary instead of the reverse condition on a turning machine.

As manufacturers of rotary broaching tools, Somma soon realized that in order to produce parts successfully there are a few basic rules that must be followed. These rules are based on understanding how and why rotary broaching works.

  • INSERTS CAN BE RESHARPENED 20 TO 30 TIMES.
    Somma Resharpenable Inserts are more economical than single usage throwaway inserts or even conventional carbide or H.S.S. form tools.

  • INSERTS CAN BE CHANGED IN LESS THAN ONE MINUTE,
    Practically eliminating machine down time for tool resharpening or replacement.

  • ONCE INSERT IS SET TO CENTER IT NEED NEVER BE RESET.
    Since inserts are all made to a master length from front to back, inserts will always be on original centerline even when changing from job to job.
