Replacement Screw for Lever Clamping Systems
The LEM8x25 lever screw serves as a central element for actuating lever clamping mechanisms in modern tool holders. Thanks to its precise thread, it optimally transfers the clamping force to the lever, which securely pulls the indexable insert into the pocket without play. An intact clamping mechanism is crucial for machining quality and dimensional accuracy during turning and grooving. This screw is an excellent replacement part for rectifying wear on the tool holder.
Technical data
- Type: Lever screw
- Designation: LEM8x25
- Thread size: M8
- Length: 25 mm
- Tightening torque: approx. 10.2 Nm
- Compatibility: Tool holders with lever system (often used with lever L5)
- Material: High-strength special steel
Applications
This replacement part is primarily used in tool holders, boring bars, and grooving holders equipped with a lever clamping system (e.g., PCLN, DCLNR/L, or PCBNR/L). The screw is widely used in serial production, general mechanical engineering, as well as tool and mold making, where fast insert changes and high process reliability are required.
Special features
The lever screw stands out due to its high accuracy of fit and wear-resistant thread, which ensures a constant clamping force over numerous change cycles. The durable material protects the screw head from premature wear caused by repeated loosening and tightening. This ensures that tool changes remain smooth and non-productive times on the lathe are effectively minimized.
