Product Overview
Horizontal mill parts are machined with the spindle oriented horizontally, which lets chips fall clear of the cut and allows the part to be indexed so several faces are machined in one setup. Fewer setups means fewer opportunities for datum error, which is why horizontal machining is the usual choice for higher volume precision work.
We run eight Okuma MA-40HA horizontal machining centres, which carry the larger scale milling work in our factory.
Key Benefits
Multi Face Machining In One Setup
The part is indexed rather than re-clamped, so feature to feature relationships hold.
Better Chip Evacuation
Chips fall away from the cutting zone, improving tool life and surface finish.
Higher Volume Throughput
Eight horizontal machining centres carry repeat production without blocking prototype work.
Consistent Repeatability
The same tolerance of +/-0.005 mm across a long run.
Application Scenarios and Who It Is For
- Production volume machined components
- Parts requiring machining on several faces
- Valve bodies and manifolds
- Gearbox and transmission housings
- Machinery components in repeat batches
If your application is not listed, send the drawing anyway. Most of our work arrives as a part nobody else wanted to quote.

Manufacturing Process and Quality Control
Drawing Review
Our engineers review manufacturability, confirm tolerances and raise anything in the drawing that would cause a problem before production starts.
Sample Approval
Free samples are offered prior to mass production, with first piece inspection recorded against your drawing.
Production Control
In-process inspection at a set frequency during the run, using the coordinate measuring machine and gauges in our inspection room.
Surface Treatment
Anodizing, sand blasting, polishing, electroplating and powder coating applied in house after deburring and cleaning.
Final Inspection
The finished lot is checked against the drawing before packing, with certification issued for the stages you require.
Packing and Delivery
Protective packing appropriate to the part, dispatched within the agreed delivery date.
Customization Options
- Material — specify a grade from our catalog, or describe the function and our engineers will recommend one.
- Tolerance — standard machining tolerance is 0.005 to 0.01 mm; tighter callouts are discussed at quotation.
- Surface finish — anodized, sand blasted, polished, electroplated, powder coated or as machined.
- Marking — laser engraving and CNC engraving for part numbers and logos.
- Quantity — from a single prototype through to long production contracts.
- Certification — certification provided at each stage on request.

Product FAQ
Why is horizontal machining better for volume work?
Chip evacuation and multi face indexing. Both reduce cycle time and setup count, which is where cost sits on a production part.
Can a prototype run on the horizontal machines?
Yes, though for a single piece a vertical machining centre is often quicker to set up and therefore cheaper.
Do you offer in-process inspection on long runs?
Yes. Operators check critical dimensions at a set frequency so drift is caught early rather than at final inspection.
How do I order this part?
Do you offer free samples?
Yes, free samples are offered prior to mass production so you can confirm the part before committing to a run.
