I-Precision's machining hall in Kota Kemuning: Doosan turning centres, a Millstar horizontal machining centre and machined parts on pallets under an overhead crane marked Safety First

Precision machined components for subsea and wellhead work.

CNC boring, turning and milling up to 4000 mm of travel, Inconel 625 and 316L cladding to qualified procedures, and CMM inspection to 0.001 mm — under one roof in Kota Kemuning, Shah Alam, since 2012.

Every job travels on a route card. This is the route.

Each order is opened in the Factory Master MRP system and follows a bar-coded route card through six stations. What happens at each one, and on which machine, is below — so you can check the fit before you send a drawing.

  1. 1

    Drawing received

    Drawing, material, quantity and date logged into Factory Master.

  2. 2

    Programming

    SolidWorks model, MasterCAM toolpaths, tools preset off the machine.

  3. 3

    Machining

    Horizontal boring, vertical turning, 5-axis turn-milling to 4000 mm.

  4. 4

    Cladding

    Inconel 625 or 316L overlay to three qualified procedures.

  5. 5

    Inspection

    CMM to 0.001 mm, dye penetrant, hardness, API thread gauges.

  6. 6

    Assembly and delivery

    Sub or full assembly, coating, documentation, dispatch.

A job number and a quotation
Logged in
Factory Master MRP

Send the drawing you already have. A 2D PDF with material, quantity and required date is enough to quote; a 3D model shortens programming.

Sales opens the job in Factory Master, which covers sales, purchasing, production, quality and warehousing, so the same record follows the part to dispatch. Raw material is controlled from receipt for full traceability.

What to include

  • Drawing or model — PDF, DWG, STEP or SolidWorks
  • Material and condition — grade, heat treatment, certificate needs
  • Quantity and whether it repeats
  • Cladding or coating if required, and to which specification
  • Inspection scope — CMM report, NDT, hardness, thread gauging
  • Required date

Materials we have published work in

  • ASTM A350 LF2 low-alloy forgings
  • AISI 4130 alloy steel
  • Inconel 718 tubing and casing hangers
  • Inconel 625 and 316L as cladding overlay

Other grades on request. Lead times are quoted per job. Typical lead times: owner to confirm

Proven toolpaths, preset tools
Sign-off
Senior precision programmer

The part is modelled and its toolpaths written before it reaches a machine, and every tool is measured on a presetter first — so machine time is spent cutting, not measuring.

  • SolidWorks3D modelling of the component and fixtures
  • MasterCAM 2017CNC programming for boring, turning and milling centres
  • Alfa-Set 33 tool presetterAll tools are preset, measured and checked before use on the CNC machine tools; measuring on the machine is eliminated.
  • Jigs, fixtures and special toolingManifold jigs and fixtures, gun drilling, CH-8 and CH-16 facing heads, ES20 / ES40 / S40 seat-pocket tools, autoclave form tool, drills and taps to suit special material grades.
