All Quik Chek's are made of 440c stainless steel hardened to 62 Rockwell C scale, stress relieved and triple stabilized, ground and lapped flat and parallel.  Run Quik Chek once a week to assure your CMM is operating properly between the yearly manufacturer calibrations.  Check diameter, linear length and squareness X to Y axis then X to Z axis.  Measure the 45 length for a volumetric check.  Quik Chek is your mechanical assurance that your CMM is within the specified tolerance of the manufacturer.  Typical checks take less than 10 minutes - less than 10 minutes for peace of mind.  Quik Chek's are available in 8 or 16 inch models.  Special sizes available upon request.

Due to the continuing emphasis on quality and the ever-increasing number of applied standards in the manufacturing environment annual gage/tool inspection by a qualified outside calibration service is no longer adequate.  This is particularly true with respect to Coordinate Machines (CMM's).  By performing inspection checks often one can be more assured that the CMM is working within the manufacturer's specifications.  Moreover, if a problem is discovered there are fewer parts to re-examine and potentially fewer bad parts produced.

Several checks should be performed on a CMM, with the most important being confirmation of: diameter, length, squareness and volumetric accuracy.  The instrument used should be highly calibrated, reliable, easy to use and be similar in nature to the types of parts being checked.

The Glastonbury Southern Gage "QUIKCHEK" utilizes three holes in a triangular pattern allowing the following checks to be easily made, specific features certified, and manufactured traceable to the National Institute of Standards and Technology.

Diameter: holes calibrated and round within .000010 on the 8-inch model and .000020 on the 16-inch model.

Length: centerline to centerline.

Squareness: angles calculated to within one arc second accuracy.

Volumetric: utilizing hypotenuse of triangle positioned anywhere on the table.

The QUIKCHEK is an excellent training tool allowing new personnel to become acclimated and more comfortable measuring with the CMM, the use of touch probes, and general inspection processes.

The unit is made of 440c Stainless Steel material, stress relieved, hardened to 62Rc and triple stabilized so it will maintain its accuracy for years. The QUIKCHEK comes with certification, application procedure and lockable storage case.

By comparing the calibrated values generated from your CMM frequently, the machine can be tracked statistically period to period.  Problems can be detected before they become critical.  Maintenance of these inspection results can help during company quality audits by helping to eliminate equipment concerns within the inspection department.

In summary the QUIKCHEK is a highly calibrated artifact using multiple hole patterns calibrated outside of the Coordinate Measuring Machine by conventional methods traceable to N. I. S. T., is certified, and simulates actual parts being inspected with hole locations, true positions, and bolt circle call outs.

The Glastonbury Southern Gage "QUIKCHEK" helps provide assurances that your CMM is working properly.
