October 8, 2026 Kyocera Double-Clamp_CP231 Turning Toolholders
The Kyocera Double-Clamp_CP231 Toolholders series achieves superior machining precision, chatter-free stability, and extended insert tool life across a wide variety of external metalworking operations. Manufactured by Kyocera, this high-rigidity clamping mechanism securely fixes cutting inserts in two directions simultaneously with a single action, making it an ideal choice for high-feed turning, facing, profiling, and interrupted cutting.
Two-Direction High-Rigidity Clamping Technology
The core innovation behind the Kyocera Double-Clamp_CP231 Toolholders system lies in its dual-force mechanical action driven by a single clamping screw:
- Dual Clamping Forces: Simultaneously exerts a pulling force to seat the insert into the pocket wall and a downward force to pin the insert securely onto the shim.
- Superior Shim Contact: Maintains complete surface-to-surface contact between the insert and the shim, even under heavy cutting forces and high feed rates (f = 0.4 mm/rev).
- Extended Tool Life: Prevents insert micro-movement, chatter, and uneven wear compared to traditional lever-lock systems (PCLN style), significantly increasing edge longevity during interrupted cutting.
- Convenient Laser Markings: Toolholder bodies feature laser-etched spare part codes and recommended screw tightening torques (e.g., CS-3D at 3.9 N·m) for quick maintenance and ordering.
Product Lineup and Toolholder Varieties
The Kyocera Double-Clamp_CP231 Toolholders series encompasses a versatile range of toolholder geometries tailored for specific approach angles and applications:
- DCLN Type (95° Cutting Angle): Designed for external turning and facing operations using CNMG 1204 inserts.
- DDJN Type (93° Cutting Angle): Ideal for external turning and profiling using DNMG 1504 and 1506 inserts.
- Expanded Lineup Options: Available in DWLN, DDHN, DVPN, DVVN, DVLN, DSBN, and DTGN toolholder styles covering cutting angles from 72.5° to 117.5°.
