"R"- ZERO HOLDER

Product catalog summary

Specifications:
- Recommended collet: FDC-AA grade
- Includes 4 screws and an adjustment wrench
- Measurement range: 0-460mm in length
- Compatible with various tool interfaces (BT, HSK, UTS, SK, etc.)
- Slim design with high precision
- Runout accuracy can be adjusted to near zero using the "R" Zero holder

Features:
- Easy to measure runout accuracy
- Rotary holder support and holder pull-in device
- Enables tool change by pulling in with 4-8kN and fixing the tool holder
- "R" Zero holder is a collet chuck with a runout adjustment function
- Accuracy can be adjusted to 0-2μm quickly
- Improves hole diameter consistency, surface roughness, and tool life

Performance Comparison:
- Conventional collet holders show larger runout at the cutting edge compared to "R" Zero holders
- Cutting data comparison shows significant improvement in hole diameter variance and surface roughness after adjustment
- Example processes include centering, drilling, and reaming with improved results using "R" Zero holders

Benefits:
- Longer tool life and better surface roughness
- Invariant hole diameter
- Reduced defects and process integration
- Prolonged tool life by approximately 1.75 times

Ordering Information:
- Various part numbers and sizes available for different holder types (BT30, BT40, CAT40, CAT50, etc.)
- Collet and spanner wrench sold separately

PAT. Having run out problems at the tool tip? NT’s patented R-Zero collet chucks offer the solution to your T.I.R problems! With “R-Zero” function HDZ High precision Slim design Runout accuracy of the cutting edge can be adjusted as closely as to Zero with “R” Zero holder. Adjustment wrench 4 Screws FDC-AA grade collet is recommended. Rotor ring Conventional Collet Holder “R ” ZERO Holder Even when runout of cutting tool at chucking side is 1μm , runout at the edge is much larger when using conventional collet chuck. “R”-Zero Setter SPZ-2 Easy to measure runout accuracy ●Rotary holder support Any tool interface can be prepared. (BT, HSK, UTS, SK etc.) ●Holder pull-in device Enables tool change by pulling in (wih 4-8kN) and fixing the tool holder. “R” Zero holder is a collet chuck with a runout adjustment function to reduce the misalignment of the cutting edge. The accuracy can be adjusted to 0-2μm in short time. This high precision “R” Zero holder realizes invariant hole diameter, better surface roughness, and longer tool life. Mueasement range 0-460mm in length
