Special-Purpose Machines (SPM)

Single-purpose pressing, drilling, assembly and checking stations, designed around one component and one cycle time.

A special-purpose machine does one job for one component. It is worth building when a standard machine is either too slow, too manual or too imprecise for the volume you are running — typically where an operation is repeated thousands of times and consistency matters more than flexibility.

We build SPMs where a standard machine cannot do the operation economically: single-purpose assembly, pressing, drilling or checking stations designed around the part, the cycle time and the operator who has to run it all day.

What we build

Tooling we make

  • Pressing and insertion stations
  • Drilling and tapping stations
  • Assembly stations for a single component family
  • Checking and verification stations
  • Fixturing and tooling built into the machine

Specification

How it is built

StructureFabricated and stress-relieved, with ground mounting faces
ScopeOne operation on one component family, not a general-purpose machine
Cycle timeAgreed at concept and demonstrated at trial
Operator interfaceSpecified by you at enquiry and confirmed at design approval
HandoverAssembled and trial run before despatch

Process

From your drawing to a working tool

  1. ConceptWe work back from the operation, the cycle time and the volume you are running.
  2. Design approvalLayout, actuation and operator interface confirmed with you before anything is cut.
  3. FabricationStructure fabricated and stress-relieved, mounting faces ground.
  4. AssemblyMachine built up with its fixturing and tooling.
  5. TrialRun against your component and your cycle time before it leaves.

Questions

Common questions

What is an SPM and when is one worth building?

A special-purpose machine does one job for one component. It is worth building when a standard machine is either too slow, too manual or too imprecise for the volume you are running — typically where an operation is repeated thousands of times and consistency matters more than flexibility.

What do you need from us to quote an SPM?

The operation, the component drawing, the cycle time you need and the volume you are running. The operator interface matters too — a machine a trained setter runs is a different machine from one an operator loads every twenty seconds.

Do you trial the machine before it is delivered?

Yes. The machine is assembled and run against your component before despatch, so the cycle time agreed at concept is a figure you have seen rather than one you have been promised.
