The broaching head is a device that, by means of a to-and-fro rotary movement and a specific inclination of the broach holder compared to the central casing of the equipment, enables the processing of regular hollows (hexagonal, square etc.) in through and blind holes. It can be supplied with vice taper fitting, metric and inch cylindrical shaft fitting and Vdi fitting. Broaching tool holders are used on production machine like single-spindle lathes, multi-spindle lathes, NC machines, cnc milling machines, drills and transfer machines. The rotation and cutting speed of the machine tool enable the removal of the material by means of a broaching tool with front profile, the same as that of the figure to be obtained.
Description and Specifications
The broaching heads and the broaches are produced with certified top quality steel, they are tempered and completely grinded. All production cycle is carried out in our factory in Italy with high precision machines and is carefully controlled. Thanks to the availability of stock, we can usually ship the material the same day as order is received.
Recommended parameters: Rotation speed (rpm): 1000-3000. Feed speed (mm/rpm) 0.01- 0.05. Diameter of the hole increased than the size of profile to be processed. Length of the hole 30-40% more than the profile to be processed. Almost all the free-machining steels and materials with resistance Rm 850 N/mm2 (> 250HB) may cause, according to the hardness of the material itself, more problems during processing (tool wear / frequent sharpening).
