Process planning

The machine is only useful when the sequence is right.

Hardened carbide, fine features and tight fits rarely come from a single operation. Our process planning links material condition, heat treatment, grinding allowance and inspection so each operation supports the next.

“The critical feature decides the route: turning for round form, grinding for fit, EDM for hard geometry, and inspection where the drawing demands evidence.”

Core processes

One part can cross several disciplines.

We combine processes as the geometry requires, rather than forcing the part through a single machine.

01

CNC turning

Pins, sleeves, bushings, shafts and round or turned geometries with controlled concentricity.

02

CNC milling

Inserts, plates, pockets, slots and custom prismatic details with multi-axis machining.

03

Precision grinding

Profile, surface and cylindrical grinding for fit, finish and hard-material edge geometry.

04

Die-sinking EDM

Fine cavities, sharp internal corners and hard-material features that cannot be cut practically.

05

Slow-feed wire EDM

Accurate profiles, split details and thin-wall geometry with minimal cutting force.

06

Inspection

CMM, height gages, vision and surface measurement applied to the features specified on the drawing.

Engineering support

Technical questions answered before the quote.

The RFQ is a review point, not a hand-off to an anonymous production queue.

01 / Drawing review

Manufacturability & tolerance

We review geometry, critical features and tolerance stack-up before confirming the process.

02 / Material

Grade & treatment guidance

Material and hardness are matched to wear conditions, impact and required service life.

03 / Production

Prototype to repeat order

The approved sample and drawing become the baseline for ongoing batch inspection.

Factory evidence

Where the parts are made.

Production, EDM and metrology sit close together on the same floor, shortening the feedback loop between machining and inspection.
