Axial Compensation & Tension-Compression Technology
When tapping on a CNC machine, even a small synchronization error between the spindle rotation and the axial feed can break the tap or strip the threads. IMI's tension-compression tap holders feature adjustable spring compensation that allows the tap to float axially. This float absorbs the synchronization lag, making it ideal for older CNC machines or when using high-speed tapping operations in tough alloys.
For modern machines with rigid tapping (synchronized tapping) capabilities, IMI offers micro-compensated chucks. These holders provide a small amount of axial compression (under 1mm) to relieve the axial loads on the tap flanks during reverse spindle rotation, extending tap life by up to 100%.
Key Tapping Products Offered
- Tension-Compression Tap Chucks (BT40, BT30): Precision-ground chucks with adjustable axial float for standard CNC and manual machines.
- Quick-Change Tap Adapters: Adapters with or without safety friction clutches that allow operators to swap taps in seconds without tools.
- Safety Clutch Adapters: Built-in adjustable clutches that slip when the tap bottoms out in a blind hole, completely preventing tap breakage.
- Boring & Facemilling Adapters: High-rigidity extensions and modular tool holding adapters for custom setup designs.
Optimized Threading Productivity
Tapping is often the final operation on a complex machined component, meaning a broken tap can lead to the scraping of a highly valuable workpiece. Sourcing IMI safety clutch tapping adapters through Valency Industries minimizes this risk, protecting your workpieces and keeping your CNC lines running smoothly.
