What it is

A small workshop in a rented industrial unit with CNC mills and lathes, producing batches of parts for businesses from drawings or CAD files.

Your first three steps

  1. Get experience or training in CNC programming and setup if you do not already have it, for example at a local college or by working for a machine shop
  2. Price up a used CNC machine, tooling and a unit on a short lease, and build a simple costing sheet for quoting
  3. Contact local engineering and product firms with sample parts and ask for small trial orders
Who pays

Local manufacturers, engineering firms, product designers, start-ups and maintenance departments.

How it makes money

Quote per part or per batch based on machine time, setup and materials. Regular repeat orders from a handful of customers keep machines busy.

Questions people ask

How much does it cost to start a CNC machining business in the UK?

Startup costs are typically around £25,000 to £120,000, depending on the machines you buy, the unit you rent and your tooling and software. Treat this as an estimate and get quotes first. Cash flow matters, as customers may pay on 30 to 60 day terms.

How much can a small CNC machining unit earn?

Monthly revenue is typically around £3,000 to £15,000, depending on your machines, the jobs you win and how busy the unit is. This is an estimate, and running the unit usually means around 35 hours a week or more. Avoid depending on only one or two customers.

What rules and insurance should I check before opening a CNC unit?

Check your unit lease terms, business rates and planning use class with the landlord and your council. Also check insurance, such as public liability, employer's liability once you hire, and product liability, plus health and safety duties for machinery, coolant, noise and dust.
