Rovic can manufacture a large variety of internal and external splines and slots using our either our Slotter machines or our Spline Broaching machine. We can produce splines, serrations and internal keyways to metric and imperial standards including tapered bores. We will accommodate any batch size from a one off up to medium size batches.
For single items or for items with unusual or non-standard profiles, it is often more efficient to manufacture a special “form” tool and generate the internal shape on the Slotting machine. The Slotter has a rotating table with a diameter of approximately 500mm. This table will hold the work piece to be machined. The rotation of the table permits the job to be orientated at any angular position so that multiple features can be produced. The machining action is achieved by a reciprocating motion with shaves off a thin piece of material on each tool pass. Because of this shaving process either an undercut or hole is required at the end of the keyway, in order to accommodate and relive the swarf generated during the cutting process.
Our Spline Broaching machine is a hydraulically driven “Pull” type broach. The broaching tool is a full form tool that is tapered towards the start end. The broach is pulled in one single motion through the work piece and at the end will form the required internal spline. Many other shapes other than splines are possible and the only limit is constrained by the availability of suitable broaches. Rovic Engineering has many broaches in stock so please contact us to check that we have the one you require.
