The processes that can be carried out with the REV Broaching Tool are, in terms of standard machining, all of those relative to broaching tab or key housings (with single or multiple timing, on cylindrical or conical holes, with or without a relief grooves, with or without 0.2mm x 45° chamfering on the base). With special tools it is also possible to execute PTOs, square, pentagonal and hexagonal holes and involute teeth, for example. 1 mm is the minimum hole size for broaching. The maximum processing depth is 200 mm, with standard machining. When it is necessary to execute considerably large key housings, it is good practice to perform the operation in two steps: a roughing phase to remove approximately 50% of the material, and a finishing phase to achieve the required size. Accordingly, you avoid excessive stress to the tool, and you improve precision and surface finish at the same time.
The materials that can be processed are:
• High and low-alloy low-carbon steel, and non-alloy steel;
• Stainless steel, quenched and tempered steel, cast iron, AVP;
• Non-ferrous materials such as aluminium alloys and titanium;
• Copper alloys, bronze, and engineering plastics.
