By the numbers
Our Principles
Four Things We Refuse to Compromise On
Material Integrity
Every batch of steel arrives with a mill certificate. We never blend grades and never substitute without written approval.
Dimensional Discipline
CMM inspection on every dimension you specify, not just the ones that fit the schedule. Reports shipped with the parts.
Honest Lead Times
We quote what we can actually deliver. If a delay is unavoidable, you hear about it the day we know — not the day before shipment.
Long-Term Engineering
Most of our customers have been buying from us for over a decade. We invest in relationships, not transactions.
Manufacturing
What is Behind the Quote
A short tour of what lives inside our plant, and why each step matters for your blade.
Design office
SolidWorks, AutoCAD and Mastercam. Engineers fluent in CAD-to-CAM, including direct import of customer STEP / IGES files.
Tool-room
CNC milling, turning and wire EDM. Fixtures built in-house to hold tight tolerances without grinding vibration.
Heat treatment
Two vacuum furnaces (12 and 30 bar quench) plus a cryogenic treatment cell. Hardness calibrated daily against a certified test block.
Grinding hall
Five-axis CNC profile grinders, surface grinders and cylindrical grinders. Coolant filtration keeps thermal growth under control.
PVD coating
Two PVD chambers (TiN / TiCN / CrN / DLC). Coating thickness measured on a Calotest rig and recorded in the batch file.
Quality lab
CMM, optical comparator, surface roughness tester, micro-hardness tester. Reports archived for ten years per ISO 9001.
