PROFILE AND KEYSEATING MACHINES Machine tools

APPLICATIONS FOR KEYSEATING MACHINES As mechanical engineers with years of experience, we are a competent partner for many different industries: from drive engineering to woodworking – the Leistritz Polymat and Polyjet series of machines are employed in just about every branch. Our design and manufacture specialists work constantly to advance our technologies. We have continuously improved our profile and keyseating technology over many decades to deliver the highest quality from one source. The customer’s benefit is always our top priority. As a reliable partner with a global service and...

↗ Keyseating - principle - advantages ↗ Keyseating - principle - advantages HOW KEYSEATING WORKS The keyseating process cuts a keyway in stepwise manner. A cutter is pulled vertically with a continual stroke movement along the borehole, combined with a horizontal thrust motion. The thrust is delivered after each stroke by a feed bar that thrusts the cutter in steps between the cutter guide bar and cutter bar. To ensure gentle machining for the tool and workpiece, the cutter is automatically lifted off before the upward movement. The keyseating machines are equipped with a twin-column...

THE MACHINE SERIES Typically, manual indexers are built onto the machine for multiple keyways. NC machines generally come as 2-axis machines (controlled axes). 7 Oblique keyways 7 Oil grooves 7 Keyways into blind holes 7 Helical keyways 7 Regular and irregular multiple-keyways/profiles (serrated/ spline/involute profiles/...) PERFORMANCE DATA OF MACHINE SERIES The “hard" keyseating machine POLYJET 50 offers users a new dimension in profile and keyway cutting. This new machine generation combines the performance of much more complex broaching machines with the flexibility and efficiency of...

TOOL SETS, CUTTERS AND CENTERING SETS Each tool set covers a specific machining range: 7 Keyway width 7 Borehole diameter 7 Keyway length The respective tool must be selected to match the machining task. The cutter required for the cutting task is selected to match the defined tool set. The cone steplessly centers the workpiece against the bore chamfer, positively locating it relative to the cutter tool.
