Manufacturing scope

Precision & post-weld machining

Turning, milling, boring, five-axis machining and post-weld machining to your drawings, tolerances and assembly requirements.

Identify manufacturing and assembly risks early

Confirm critical tolerances, datums, quantities and special processes before planning machining and inspection.

01

Multi-part review

Drawings, materials and manufacturing processes reviewed together.

02

Dimensions and fits

Datums, tolerances, hole patterns and fits.

03

Special processes

Heat treatment, grinding, finishes and material records.

04

Post-weld machining

Mounting faces and holes on frames and bases.

Manufacturing scope

Use these product groups to assess project fit. We confirm the scope against your drawings and requirements.

01

Turned parts

Shafts, pins, sleeves, flanges, precision rings and stepped parts.

02

Housings and blocks

Valve bodies, manifolds and complex bore patterns.

03

Plates and mounting parts

Baseplates, clamps, brackets and equipment interfaces.

04

Post-weld machining

Datum faces, mounting faces and holes on frames and bases.

One project contact

One project plan connects drawing requirements, process handoffs and release criteria.

01Drawing reviewConfirm drawing revisions, materials, tolerances, standards, quantities and delivery dates.
02Manufacturing planAssign in-house and supplier work, process steps, inspection checkpoints and schedules.
03Manufacturing processFollow the agreed process and record checks of critical requirements and any deviations.
04Inspection & testingRelease after checking agreed dimensions, appearance, quantities and inspection records.
05Packing & deliveryProtect machined surfaces, check identification and packing lists, and coordinate dispatch and transport.

Process control

We check critical requirements during production. Batch production begins after first-article approval, and shipment follows final inspection and document review.

01

Drawing review

Revision, datum system, tolerances and assembly relationships.

02

Materials and blanks

Grade, condition, heat numbers, castings, forgings and weldments.

03

First-article approval

Dimensions, tools, fixtures and process parameters.

04

In-process inspection

Critical dimensions and fits checked during machining.

05

Final release

Dimensions, appearance, quantity, identification and records.
