Prototype machining
We machine prototype components to help validate form, fit and manufacturing approach before repeat production. For suitable work, machining tolerances can be held within 0.01 mm.

Circle Line Engineering supports prototype machining in Auckland using CNC milling, CNC turning, conventional turning and engineering design capabilities.
We machine prototype components on CNC mills, CNC lathes and conventional lathes at our Ōtāhuhu workshop in Auckland, with design support available when needed. Precision engineering since 1994.
We machine prototype components to help validate form, fit and manufacturing approach before repeat production. For suitable work, machining tolerances can be held within 0.01 mm.
The workshop is set up to handle one-off engineering jobs as well as repeat production.
SolidWorks design support is available when a project needs additional development before manufacture, and specialist partners can provide heat treatment, precision grinding and other processes where required.
For suitable prototype work, we can hold in-house machining tolerances within 0.01 mm and work accurately to drawings specified using GD&T.
Yes. Our engineering design service uses SolidWorks for 3D modelling and detailed drawings, allowing design development to be coordinated with prototype machining.
Yes. Where required, we can coordinate partner processes such as precision grinding, heat treatment and other specialist processing alongside in-house machining.
Yes. The same workshop supports both prototype work and repeat production, allowing the manufacturing approach to develop as quantities and project requirements change.
Send drawings, dimensions, quantities and project requirements, and our team can review the requirements and confirm the most suitable manufacturing approach.
