Samchully Machinery collet chuck systems (CR, QC, and DC series) deliver high-speed workholding performance tailored for bar-fed CNC turning centers and multi-tasking lathes.
Compared with conventional jaw chucks, collet chuck bodies feature minimized mass and symmetrical radial profiles, decreasing centrifugal force loss and enabling sustained spindle rotation velocities up to 7,000 RPM.
The advanced QC Quick-Change mechanism allows operators to switch collet segments within seconds using a manual changeover fixture without removing the chuck body from the spindle nose.
The CR fixed-length design incorporates a push-to-close collet sleeve geometry that eliminates axial part displacement during clamping, ensuring strict workpiece shoulder length tolerances during automated bar feeder cycles.
Collet chucks mount directly onto A2-5, A2-6, and A2-8 spindle noses, accepting standard DIN 6343 161E, 173E, and 185E collets.
- Elevated rotational speed thresholds: balanced body dynamics support continuous spindle operations up to 7,000 RPM
- Rapid changeover tooling: QC Quick-Change mechanisms enable complete collet replacement in under 15 seconds
- Zero axial part shift: stationary workpiece stop geometry preserves strict longitudinal part positioning

Samchully Replacement Chuck Jaws: Standard & High Soft Jaws SB, HB Series & Hard Step Jaws HJ, SHJ Series
Samchully Machinery precision replacement chuck jaws (SB, HB, HJ, and SHJ series) provide rigid torque transmission from chuck master slides onto precision turned components.
Unhardened soft jaws (SB and HB series) are machined from normalized S45C carbon machinery steel, allowing machinists to bore dedicated circular contours in situ under live clamp pressure, delivering part runouts under 0.01 mm across critical mounting diameters.
Extended-height soft jaws (reaching up to 150 mm) support oversized step faces and long shafts, while lightweight high-tensile aluminum jaws slash centrifugal gripping force attenuation on high-RPM spindle programs.
Hardened step jaws (HJ and SHJ series) are hot-forged from SCM440 chrome-molybdenum alloy steel and induction hardened to 58–62 HRC across aggressive serration teeth, embedding firmly into mill scale on hot-rolled bars and forged billets to withstand extreme cutting moments without slipping.

Precision Mechanical Kinematics, Metallurgy & Workholding Rigidity
Samchully Machinery Co., Ltd. workholding systems and machine tool accessories are engineered to sustain intensive, continuous multi-shift production regimes across high-speed CNC turning and milling centers worldwide.
Core mechanical reliability across the HS power chuck line and S-series rotary hydraulic cylinders is anchored in heavy-section forgings of high-tensile chrome-molybdenum alloy steel (SCM440) subjected to deep core normalization.
Master jaw slideways and precision internal wedge surfaces undergo high-frequency induction hardening to 60–62 HRC followed by CNC coordinate grinding, preventing micro-galling and maintaining consistent radial concentricity over millions of clamping cycles.
The balanced wedge-plunger geometry optimizes force transmission from hydraulic drawbars into radial gripping vectors while minimizing sliding friction losses.
Dedicated high-pressure lubrication ports distribute grease directly into internal bearing ways, preserving gripping retention at top spindle velocities.
Hydraulic System Integrity, Integral Safety Check Valves & CNC Interlocks
Operational safety in high-speed rotary workholding is paramount for modern automated manufacturing cells. Samchully Machinery S and SH series through-hole rotary hydraulic cylinders integrate dual pilot-operated check valves engineered directly into the rotating cylinder body.
In the event of sudden hydraulic pump failure, pressure line dropouts, or power interruptions, the pilot check valves lock operational hydraulic pressure inside the piston chambers, preventing workpiece slippage or ejection under maximum spindle centrifugal forces.
Precision inductive proximity switches mounted along adjustable exterior brackets interface seamlessly with machine tool CNC controllers (Fanuc, Siemens Sinumerik, Heidenhain, Mitsubishi), verifying definitive clamped and unclamped piston stroke positions before spindle acceleration can initiate.
High-Accuracy Machine Kinematics: 4th & 5th-Axis Tables and Self-Centering Steady Rests
Samchully Machinery HR, HDR, and TR series CNC rotary tables enable simultaneous 4-axis and 5-axis machining of complex aerospace impellers, turbine blades, and precision dies on standard vertical machining centers.
The dual-lead worm and wheel drive system features ground phosphor-bronze wheels paired with induction-hardened alloy worms, allowing precise backlash adjustment without mechanism disassembly.
A powerful disc brake develops clamping torques up to 3,200 Nm, eliminating rotary platter deflection during aggressive rough-milling cuts.
For long shafts and tubular workpieces, Samchully SLU hydraulic steady rests provide rigid three-point self-centering support, maintaining center alignment with spindle axes to within 0.005 mm while internal air curtains prevent ingress of swarf and abrasive grinding sludge.
Workholding Optimization: Chuck Jaws, Collet Chucks and Connecting Hardware
Selecting the correct chuck jaws and collet configurations ensures workpiece dimensional accuracy and tool clearance.
Soft jaws (SB and HB series) machined from malleable S45C carbon steel are bored directly on the lathe spindle under active hydraulic pressure, providing complete circumferential contact and part runout within 0.01 mm.
Hardened step jaws (HJ series) feature aggressive induction-hardened serrations that bite securely into hot-rolled scale and forged billets for heavy-duty roughing cuts.
For high-speed bar turning up to 7,000 RPM, Samchully CR and QC collet chucks minimize rotating mass and eliminate centrifugal jaw force attenuation. The CR fixed-length design prevents longitudinal part displacement during clamping, ensuring strict shoulder length tolerances on bar-fed parts.
