Precision Machined Plates

A plate is defined by three things: flatness, parallelism and uniform thickness. Get those right and everything assembled on it behaves; get them wrong and the error propagates through the whole stack.

Types

Base plates, cover plates, separator plates, mounting plates and vacuum or fluid distribution plates, with bores, threads, pockets and sealing grooves as required.

The geometry that matters

Flatness across the working face, parallelism between faces and thickness consistency. These are measured on a Zeiss CMM for geometry and position, the TRIMOS V5 height gauge for heights and steps, and the AI-Vision system for fine features rather than inferred.

Materials

Aluminium, stainless steel, titanium and engineering plastics, depending on whether stiffness, corrosion resistance, weight or insulation dominates.

FAQ

Frequently asked questions

Flatness is quoted per plate based on size and material; tight work is machined in stages to limit stress and measured on a Zeiss CMM for geometry and position, the TRIMOS V5 height gauge for heights and steps, and the AI-Vision system for fine features.
Yes — with grooves, bores and sealing faces machined and verified for flatness.
Plate envelopes are quoted per part; send the drawing and we confirm size and achievable tolerances.
