Production and regrinding of all known broaches with the 6-axis CNC grinding machine.
The 6-axis CNC grinding machinecorvusBBAwith its well thought out, attractive design is the leader in broach grinding machine. It is the result of years of co-operation with broach tool manufacturers from all over the world. The CNC grinding of broach tools is possible in a single clamping grinding gullets, spiral flutes, profile, spiral profile, clearance angle, chamfers, cylindrical grinding or surface grinding and all with the highest precision. Complete processing OD and face, up to 2800 mm cutting length, diameter up to 400 mm, maximum workpiece length that can be clamped 3500 mm. With its T-slotted table, the machine envelope can accept steady rests, tailstocks and magnetic chucks.
In all likelihood, the following broach tools and broach needles are ground the world over on acorvusBBA:
Internal broach tool: Profile broaching tool, round, polygonal, rectangular, hexagonal, keyway, feather ke
y groove
External broach tool: Flat broaching tool, concave tool
hard broach tool
