MicroCentric

PPC Series Chucks feature a dualactuator design for superior rigidity andunmatched accuracy in a draw tubeactuated design. PPC chucks are theideal choice for precision finishing opera-tions such as hard turning, sub spindles,and grinding.

The World’s Most Accurate Power ChuckImprove productivity andlower costs by enhancingworkpiece quality . . . . . .through accurate and repeatable workholding.Manufacturers that are able to maintain closeconcentricity across a workpiece's operationsequence benefit from lower scrap rates, reducedcycle times, and increased production capacity. Byholding close tolerances and minimizing the amountof material left for finishing operations, you not onlyreduce your cost per part, but you end up with moreparts produced at the end of each shift. Theaccuracy of MicroCentric PPC Series Chucks alsoprovides the capability to improve parallelism,roundness, and squareness, as well as holdingcloser size tolerances.

Accuracy to 0.0001" TIRStandard repeating accuracy of PPC chucks is .0001"(0.0025mm) TIR maximum radial and lateral runout.

QC Precision Change Jaw Locating SystemPatented precision change jaw locating system reduces setup time by maintaining .0002” (0.005mm) runoutafter changing top jaws. MicroCentric’s QC system saves valuable set up time up by eliminating theremachining of top jaws or indicating in the chuck in order to maintain close workpiece concentricity. PPCchucks are qualified so jaws can be changed between chucks and maintain .0008” (0.02mm) TIR runout.

QC System Accuracies• .0002" (0.005mm ) TIR max runout when top

jaws finished and replaced on same chuck• .0008" (.02mm) TIR max runout when top jaws

finished on another QC chuck (same model)

QC System DesignQC top jaws are located by two tapered buttonsmounted in the master jaw. QC top jaws featureprecision finished taper seats that are located by thetapered buttons. QC top jaws seat on the OD of thetapered buttons and the face of the master jaw,assuring high accuracy and rigidity.

Accuracy is the total indicator reading (radial and lateralrunout) of a master gage measured 1.00” (25.4mm) from thetop face of the standard top jaw at 1/2 max draw tube force.Total jaw stroke.Total clamping force.Maximum speed with standard top jaw at max draw tube force.Without top jaws and spindle mounting plate.

*Weights are per piece

Blank QC Top Jaws are made from A-2 tool steel. The tapered locatingholes are precision jig bored for accurate location. QC jaws can be heattreated with minimal distortion to a hardness up to Rc 62.

Special QC Top Jaws including blank pie-shaped jaws are quoted uponrequest.

QC jaw turning fixtures simulate the locating pattern of a QC chuck.They are used to rough machine Blank QC Top Jaws off-line to maxi-mize a machine's production capacity. The clamping position of the jawturning fixture is set in the middle of the chuck's stroke. Other positionsare available upon request.

Loading Rings

Chuck Lubricant

Kluber ALTEMP Q NB 50 is the recommended lubricant for PPC chucks.ALTEMP Q NB 50 is a white lubricating paste containing a mineral baseoil, a barium complex soap and inorganic solid lubricants. This lubricanthas been found to improve the sliding characteristics of moving chuckcomponents and enabling constant clamping force. It prevents stick-slipand protects against fretting and tribo-corrosion in frictional or positiveconnections. ALTEMP Q NB 50 is resistant to oils and water solublecutting fluids.

Grease Guns

The H-1 is a pump style oil gun with an internal reservoir and includes atip suited to the grease fittings on PPC110 models.

The P-1 is a lever operated cartridge style grease gun with a tip suited tothe fittings on PPC165 and larger chuck models.

Loading rings are used to set the chuck in a clamping position formachining top jaws. CR loading rings are a cam design which provideeasy adjustment of the loading position for OD clamping. LR loadingrings are used for ID clamping jaws.
