A tool that leaves the factory inside tolerance and a tool that arrives on your shop floor inside tolerance are not the same claim. The difference is measurement, and measurement is what this page describes.
Six checkpoints before your tools ship
01 · Incoming material
Carbide rod is verified on arrival for hardness and grain size. A rod out of specification is rejected before it reaches a machine.
02 · First article
The first tool of a run is measured against the drawing before the rest of the batch is ground. If it is out, the batch does not start.
03 · Edge inspection
Cutting edges are examined under microscope for micro-chipping. This is where a grinding problem shows up before it becomes a batch problem.
04 · Optical measurement
Profile, runout and helix are measured on the optical unit — measured on the tool itself, not inferred from the machine settings.
05 · Coating verification
Coating thickness and adhesion are checked per batch, because a coating that did not take is not visible on the outside of the tool.
06 · Records archived
Inspection data is filed against your order number and kept, so a question about a specific batch has an answer.
Equipment behind the checks
| Equipment | Used for |
|---|---|
| ZOLLER »genius« | Optical measurement of profile, runout, helix and edge geometry |
| Microscope edge inspection | Micro-chipping and edge condition before batch release |
| Coating thickness verification | Coating thickness and adhesion per batch |
| Hardness and grain size testing | Incoming carbide rod verification |
What you can ask for
- Inspection data with the shipment — specify it on the order and we file the batch records with the packing list.
- First-article approval before volume — standard practice on custom geometry, and available on standard items if your process requires it.
- Certificates of conformity — issued for the batch on request.
- Sample retention — where an order needs a retained sample held against future deliveries, tell us at quotation stage.
