Precision manufacturing capability
Precision milling and turning support for prototypes, low-volume parts, and repeat production—built around your drawings and quality requirements.
Project guide
Milling typically addresses pockets, faces and non-rotational features; turning addresses features around a common axis. Parts combining these features may need multiple operations.
Decision guide
Milling is a starting point for pockets and features on several faces. Turning is a starting point for diameters about a common axis. A part with both feature groups may need combined or separate operations.
| Design scenario | Route to discuss | Decision that affects the quote |
|---|---|---|
| A housing with a pocket and a bolt pattern | Milling | Tool access, internal radii, datum transfer and permitted fixture marks |
| A sleeve with a bore and outside diameter | Turning | Wall stiffness, workholding and the relationship between bore and outside diameter |
| A shaft with a transverse hole and a flat | Turning with secondary features | How angular position and alignment are maintained across operations |
| A conductive part with an inaccessible internal profile | EDM feasibility review | Whether wire or electrode access is possible and what surface condition is accepted |
Compare proposed routes against the same drawing revision and acceptance criteria. A lower setup count does not, by itself, demonstrate a lower total cost or a better result.
Guide updated . Confirm the manufacturing and inspection scope for your actual order.
Manufacturing scope
Bolar Precision supports milling and turning for prototypes and repeat orders. Review the complete geometry before choosing a route: a process name alone does not establish whether every feature can be made and verified.
| Part requirement | What affects feasibility | What to agree |
|---|---|---|
| Envelope and access | Overall geometry, pocket depth, tool access and workholding | Accessible features, setups and surfaces used for location |
| Fits and tolerances | Datum relationships, thin walls, critical bores and mating faces | Which features control acceptance and how they will be measured |
| Material and finish | Specified grade, starting condition and post-finish dimensions | Material documentation, finishing scope and protected surfaces |
Part review
Use this illustrative part to identify what your own drawing and quotation need to resolve. The image does not represent a delivered customer order.
CNC machining
A housing that must mate with another component
Review the internal pocket, mating faces, hole positions and the drawing revision together. Mark the fits that control assembly; define finish and masking where dimensions must be protected.
Flexible support from initial parts to repeat orders.
Machining routes selected around part geometry.
Requirements reviewed and documented before production.
Coordinated finishing and inspection for completed parts.
What we support
A practical range of CNC machining services for precision parts across prototype and production requirements.
01
Precision milling for prismatic parts, housings, brackets, and components with detailed machined features.
02
Turning support for shafts, sleeves, spacers, bushings, and other rotational components.
03
Responsive manufacturing support for design validation, functional testing, and early project stages.
04
Controlled processes and documented requirements for stable, repeatable production orders.
Material review
These material families are starting points for discussion. Confirm the exact grade, condition, stock availability and documentation for the reviewed order.
| Material family | Application questions | Information for review |
|---|---|---|
| Aluminum alloys | Weight, mating fits, coating and cosmetic requirements | Grade, temper, finish and post-finish dimensions |
| Stainless and alloy steels | Strength, corrosion exposure and heat-treatment condition | Grade, condition, hardness requirement and verification |
| Brass and copper | Conductivity, joining, surface condition and handling | Grade, functional contacts and finish requirements |
| Engineering plastics | Temperature, chemical exposure, stiffness and dimensional stability | Specified polymer grade, operating environment and critical fits |
Order handover
Resolve tool access, datum transfer, finishing and inspection before approving the route. Record changes against the drawing revision so the same scope carries into repeat orders.
Quality assurance
Inspection planning is aligned with the supplied specifications, critical dimensions, and required project documentation.
Common project questions
Yes. Include the complete geometry and identify the features that must remain aligned. The proposed route and any additional operations need a project review.
Describe the operating conditions and the properties that matter. Mark the material as open for discussion rather than choosing a grade only to complete the RFQ.
