Parts Across Five Sectors

The requirement is what matters, not the label. Every part links to its industry page

Sector By Sector

What The Parts Have To Survive, And How We Machine Them

Each industry page explains the requirements we see most often, the materials and finishes that come with them, and links to the parts and cases we have delivered there.

Industrial Automation

CNC Machining for Industrial Automation

Fixture plates, end-of-arm tooling, brackets, rails and housings for automated equipment, machined to the dowel and bolt positions that decide whether an assembly goes together. One shop for the parts and the fixtures that hold them.

  • Assembly Fit: Dowel and bolt positions are measured from the same datum your assembly uses, so the part locates on the first try instead of being drilled to…
  • Interchangeability: Repeat batches are machined from the retained program and fixture, so a replacement part interchanges with the original without hand fitting.
  • Batch Consistency: Identical parts in a batch are checked as a set on the granite plate, not one representative piece, so a bowed plate or a shifted pattern…

Semiconductor

CNC Machining for Semiconductor Equipment

Carrier plates, nest plates, handling fixtures and equipment brackets for semiconductor and substrate handling, machined for flatness, hole position and clean, burr-free edges, and measured free of the fixture rather than clamped in it.

  • Flatness: Thin plates are roughed, released and finished with light passes, and flatness is measured on a granite plate after the part is free, not while it…
  • Position Accuracy: Hole and pocket patterns are checked for accumulated pitch across the whole plate on the vision measuring system, because a small error repeated across a grid…
  • Clean Surfaces: Edges are deburred and inspected; parts are handled and packed so functional faces are not scratched or marked between the machine and your dock.

Medical Devices

Precision Machining for Medical Devices

Assembly fixtures, equipment components and positioning nests for medical device production, machined to a confirmed material grade with the inspection record and material certificate travelling with the batch.

  • Material Compatibility: The grade on the drawing is the grade that is machined.
  • Surface Condition: Edge breaks, deburring and cleaning are written into the traveller, and functional faces are inspected before packing rather than assumed from the machining.
  • Traceability: Every batch has a first-article report; repeat batches are built from the retained program and fixture and reference the same drawing revision.

Automotive

CNC Machined Parts for Automotive Equipment

Stamping die inserts, forming die blocks, ganged wire-cut tooling and equipment components for automotive production, machined in tool steel with the profile cut after heat treatment and the accumulated pitch checked across the set.

  • Process Order On Hardened Parts: Rough mill soft, heat treat, then wire cut the profile last, so the hardening distortion is removed by the final operation rather than left in the…
  • Accumulated Pitch: Ganged inserts and blade sets are checked for the total across all positions, not only the pitch between neighbours, because the accumulated error is what shows…
  • Wear Resistance: Tool steel grade and hardness are confirmed before the quote and recorded on the batch, and hardness is checked on the bench tester when the drawing…

Electronics & Robotics

CNC Machining for Electronics & Robotics

Connector tooling inserts, robot grippers, laminate insulators, small carriers and sensor mounts, machined where the features are small, the sections are thin and the finish has to match across a batch.

  • Small Features: Slots, blades and hole rows below cutter size are wire cut, and features below hand-tool resolution are measured on the vision measuring system.
  • Thin Sections: Laminate and plastic sections are backed at the exit face and drilled last so holes and thin webs stay clean at breakout.
  • Position Across An Assembly: Grippers and mounts are machined so the pad, finger and manifold positions agree with the base plate they bolt to, then assembled and checked as one…

The Requirement Matters, Not The Label

A bracket for a packaging line and a bracket for a test rig are quoted the same way: by material, tolerance, finish and quantity. Send the drawing, tell Owen what the part has to survive, and you get a price and DFM notes within 24 hours on business days.
