Frömag 4 7 ton electromechanical short stroke broaching machine 

Stroke Broaching Machines The procedure short stroke broaching is a special type of application invented by FROMAG and protected by patent law. This procedure is a highly economic process to produce keyways in internal bores, in large batches, and fully automatically in several passes. Special designed short broaches facilitate a wedge to be pushed behind the broach automatically. This avoids the manual manipulation of shims to be used for multiple passes to gain the required keyway depth. High broaching and return speeds result in a high productivity and reduce the unit cost. Compared to conventional, vertical-, or horizontal broaches, the short stroke broaching machine offers due to its compact design, and the short broaches 4-5 times shorter than standard broaches and considerable space reduction. This model range is especially used for: Capacities depending on model range: Machining of keyways according to DIN or other Pulling force: 4-7 tons 40-70 kN standards for large recurrent batches and Stroke length: max. 750 mm applications with a stress of short cycle times in automatic machine mode.
