MicroCentric Precision Power Chucks (Draw Tube Actuated) PPC Series Chucks feature a dual actuator design for unmatched rigidity and repeating accuracy in a draw tube actuated design. PPC chucks are the only choice for precision finishing operations, such as hard turning, sub spindles, and grinding. A patented precision change jaw system increases productivity by maintaining .0002” (0.005mm) TIR after jaw change without indicating or remachining top jaws. QC Precision Change Jaw Locating System Patented precision change jaw locating system reduces setup time by maintaining .0002” (0.005mm) runout...

MicroCentric Quick Change Collet Chucks MicroCentric Quick Change Collet Chucks feature a segmented vulcanized collet. Quick Change Collets are changed in seconds by collapsing the collet with a changing fixture and removing it from the chuck. Collet Chuck Features • • • • • Change collets in 15 seconds .0004" (0.01mm) TIR maximum part runout Parallel clamping design Large clamping range - up to +/- .040” (1mm) All chuck components made from hardened alloy steel precision ground for accuracy and long term performance. • Modular design is adapted to machine’s existing hydraulic actuator and draw...

MicroCentric S Pad Collet Chucks MicroCentric S Pad Collet Chucks feature a segmented vulcanized master collet. This low profile master collet results in a shorter OAL compared to conventional S Pad chucks. A shorter chuck length provides greater rigidity and maximizes the machine’s Z axis travel. MicroCentric S Pad Collet Chucks also accept MicroCentric Quick Change Collets for increased flexibility and accuracy. Vulcanized Master Collet • MicroCentric S Pad Master Collets are shorter than conventional spring type master collets • MicroCentric’s segmented vulcanized design produces parallel...

MicroCentric Quick Change & S Pad Collet Chuck Models ND - Dead Length The collet is coupled in the chuck body and remains fixed as the tapered sleeve moves forward when the chuck is actuated. Low profile dead length design for maximum tool clearance on sub spindle. Internal mounting for part stops and ejectors. The collet is coupled in the draw tube adapter and is drawn into the tapered seat as the chuck is actuated. Patented dead length design for use with servo bar loaders. The NDR chuck is actuated to clamp as the draw tube is pulled into the machine spindle. Pull back design with a mounting...

MicroCentric Dead Length Collet Chucks (5C / 16C / 3J) MicroCentric Conventional Collet Chucks are available in Dead Length and Pull Back models for 5C, 16C, & 3J collets. All components are made from hardened and precision ground alloy steel for accuracy and long term performance. Modular design permits chucks to be adapted to any machine spindle configuration. Low profile nose design provides maximum tool clearance. Collet Chuck Models • Standard dead length design (5C / 16C / 3J) • Low profile dead length design (5C) • Pull back design (5C / 16C / 3J) Collet Chuck Features • All chuck components...

MicroCentric Air Cylinders & 5C Air Collet Closers MicroCentric LDZ Air Cylinders feature a high performance precision rotary air bearing assembly. The air bearing incorporates a hardened steel journal and a housing supported by high speed ball bearings. This advanced design is combined with MicroCentric's precision manufacturing capability to produce a line of air cylinders of unmatched performance and reliability. Air cylinders offer fine adjustment of draw tube force to prevent distortion of workpieces during clamping as compared to hydraulic actuators. LDZ Air Cylinders can be adapted to...

MicroCentric High Precision Diaphragm Chucks MicroCentric MBS Chucks are ideal for production turning, grinding, and milling applications, as well as clamping delicate workpieces with minimum distortion. MBS chucks require no maintenance and are especially suited to abrasive and highly contaminated environments since there are no exposed moving parts. MBS chucks are available in self-contained and draw tube actuated models. MBS Chuck Features • Repeating Accuracy to .0001" (0.002mm) TIR • Low maintenance, no lubrication required, and no exposed moving parts to wear out or become contaminated...

PMC Production Milling Chucks MicroCentric PMC chucks are a low profile manually actuated concentric clamping system for vertical and horizontal machining centers, milling machines, and grinders. PMC chucks integrate with tombstones and pallets to provide the ultimate in high productivity and high precision workholding. PMC chucks are clamped and unclamped on the top face enabling more chucks to be ganged together compared to side actuated models. PMC Design & Features • Concentric clamping • Low profile square body design • Two stage clamping - fast initial jaw stroke for large opening and primary...
