Conventional / Manual Machining
Conventional machining uses manually operated lathes, milling machines, shapers and drilling machines. It remains the fastest and most economical route for one-off parts, repairs, modifications and simple low-volume work where CNC programming time is not justified.
What it is
A skilled machinist sets up and controls the machine by hand, reading the drawing and measuring as the work progresses. There is no program to write, so simple parts can be started immediately.
Manual machining is also well suited to repair work: re-boring, re-facing, turning down worn journals, cutting keyways or modifying an existing part to fit.
Typical applications
- Breakdown and maintenance parts
- One-off shafts, bushes and spacers
- Modifications to existing parts
- Keyways, slots and simple drilling
- Large or awkward parts for repair
Suitable materials
- Mild and alloy steels
- Cast iron
- Stainless steel
- Brass, bronze and aluminium
- Plastics
Points to consider
- For more than a handful of identical parts, CNC is usually more consistent and cheaper per piece.
- Complex contours and 3D shapes need CNC.
- For repairs, share the worn part or photos plus the original size so the right allowance is left.
- Urgent breakdown jobs benefit from a clear sketch with critical sizes marked.
Frequently asked questions
Is manual machining still used?
Yes. For one-off parts, urgent breakdown spares and repairs, manual machining is often quicker and cheaper than programming a CNC machine.
Can you make a part from a broken sample?
Usually yes. We measure the sample, confirm critical sizes and material, and machine a replacement. A drawing is made where needed.
When should I choose CNC instead?
When you need more than a few identical parts, tight repeatability, or complex shapes. CNC gives better consistency on repeat orders.
