INSPECTION OF GEAR SHAPER CUTTERS

Cutters are 100% inspected using dedicated inspection equipment. This is controlled by our in house system to ISO 9002 and equipment is maintained and traceable to NAMAS National Standards.

INSPECTION OF THE BODY

The body of each tool is inspected by conventional methods to ensure that the bore of the tool is geometrically correct in size, parallelism, roundness and square to the datum face.
The same assurance is achieved on shank type tooling - by inspecting tapers to national standards and verifying concentricity to its centers.

INSPECTION OF THE CUTTER TEETH

Various dedicated gear testing machines are used to inspect involute tooth form, measure the tooth to tooth pitch error, the accumulated pitch error and concentricity of the teeth to either the bore or the centers, also the lead error of helical teeth.
Individual machines are used for involute and lead or pitch and concentricity.
Alternatively a Klingelnberg CNC gear testing machine is used which will inspect a cutter in all its elements and print out all the errors found compared with the tolerances as specified by DIN.1829. The final reports are laid out using both graphical and numerical representations.
