CUSTOM PART MANUFACTURING
Custom CNC
Machining Services
ProleanTech provides custom CNC machining for metal and plastic parts, from prototypes to production batches. Send your drawing for a quotation covering machining, finishing and inspection requirements.
CNC milling, turning &
multi-process machining
CNC machining removes material from solid stock using programmed cutting tools. ProleanTech combines milling, turning and secondary operations to produce custom components, with material, finish and inspection requirements reviewed before manufacture.
CNC milling
Pockets, planar faces, holes and complex contours for housings, brackets, fixtures and structural components. Three-axis and multi-axis routes are selected around tool access, orientation and critical features.
CNC turning
CNC turning, also called CNC lathe machining, produces diameters, bores, shoulders, grooves and threads for shafts, sleeves and connectors. Radial holes or flats can be reviewed for live-tool or secondary machining.
Turn-mill machining
Rotational and milled features on the same component. Review whether combining operations can reduce transfers and support feature relationships.
Swiss turning
Swiss turning supports small, slender components close to the cutting zone. Stock, geometry and production requirements determine whether it is the appropriate route.

Custom CNC machined parts
for your assembly
Our machining service covers components that locate, connect, support and enclose an assembly. The part’s function guides the process route and the features that need inspection.
Housings, enclosures & brackets
CNC-milled housings, enclosures and brackets can combine pockets, mounting holes and mating faces in one component. Share interface datums, critical hole patterns and cosmetic requirements so these features can be reviewed together.
Shafts, bushings & connectors
CNC-turned shafts, bushings and connectors combine controlled diameters, bores, shoulders and threads. Identify the bearing fits and sealing surfaces that determine inspection and final acceptance.
Jigs, fixtures & equipment parts
Machined jigs, fixtures and equipment parts support positioning, workholding and replacement applications. Locating features, wear surfaces and hardness requirements guide the manufacturing route; replacement parts need an approved drawing or sufficient dimensional information.
Typical applications include automation, industrial equipment, electronics and vehicle assemblies. Aerospace and medical projects require the relevant material records, inspection scope and application qualifications to be agreed separately.
Metal and plastic CNC machining.
Start with the right specification.
ProleanTech machines metals and engineering plastics for structural, thermal, electrical and sliding applications. We review the specified grade, condition and stock availability alongside the geometry and finish.
Material grades and stock availability are confirmed with your quotation. Please specify the required grade, condition and material documentation.
Have a material in mind?
Include your drawing, material grade and quantity. Our team will review stock availability and the material’s implications for machining and finishing.

Surface finishes for
CNC machined parts
Machining and surface treatment are coordinated around the part’s functional and cosmetic requirements. Finishing can affect dimensions, fit and edge detail, so masking and final acceptance are considered with the process route.
Include the finish in your machining quote.
Share the substrate, treatment specification and masked surfaces. The quotation brings machining, finishing and final inspection into the same order scope.
Your files stay confidential. Optional NDA ↗
CNC machining tolerances
& inspection requirements
We review dimensional and geometric requirements against the material, part size, workholding and finishing route. Critical fits, datums and functional surfaces guide the inspection scope agreed for your order.
Send the functional requirements
- Fits & geometryFeature-level dimensions, datums and geometric tolerances for mating surfaces.
- Threads & holesSystem, pitch, class, depth, engagement and any gauging requirements.
- Surface conditionRoughness value and units, edge breaks, burr restrictions and cosmetic zones.
- Final acceptanceClarify whether dimensions apply after coating, plating or heat treatment.
Agree the acceptance criteria before machining.
Part envelope, thin walls, deep cavities and slender features affect stability, tool access and measurement. Send these details with your tightest tolerances so feasibility can be reviewed together.
For your order, the accepted drawing and quotation establish the applicable tolerances. If you require a general-tolerance standard, include the designation, class and edition. Critical fits and geometric controls should be stated individually.
Design for a better
machining outcome.
Review the features that influence tool access, dimensional stability and machining cost before production.
Put your critical features in front of an engineer.
Send your drawing, material and quantity. We’ll review tool access, critical features and the manufacturing route before the order scope is agreed.

What determines CNC machining cost?
Material grade and stock size, machining time, setups, tool access, tight tolerances, finishing and inspection all contribute. Request prices at prototype and production quantities to compare the setup allocation. An urgent schedule also depends on stock and capacity; the quotation confirms the proposed lead time.
CNC machining questions,
answered.
What CNC machining services does ProleanTech provide?
Our CNC machining service covers milling, turning, turn-mill and Swiss turning routes, with drilling, threading, grooving and other secondary features reviewed as part of the complete component. Material selection, finishing and inspection are coordinated around your drawing.
Can you machine both metal and plastic parts?
Yes. The service includes aluminum, steel, stainless steel, brass, copper, titanium and engineering plastics such as POM, ABS, PC, PMMA and PEEK. Specify the exact grade and condition; availability and suitability are confirmed in the quotation.
How do I choose milling, turning or five-axis machining?
Start with the geometry. Turning suits rotational features; milling suits pockets, planar faces and non-rotational contours. Multi-axis machining can improve access to angled or complex features, but it is not necessary for every part. Send the complete model and drawing for route review.
What tolerances and maximum part sizes can you supply?
We review tolerance and size feasibility against your material, part geometry and finishing requirements. Include the overall dimensions, datum scheme and tightest feature tolerances in your drawing. Accepted limits and inspection requirements are confirmed in the quotation.
Can I order a prototype before production?
Yes. Include prototype, pilot and production quantities in your request. If approval of a first article is required before the batch, state the inspection and approval criteria so they can be included in the order plan.
What files do you need for a CNC machining quote?
Send a 3D model, a dimensioned drawing and revision, material grade, finish, quantity, required date and delivery destination. Mark critical fits, threads, roughness and inspection needs.
Do you provide material certificates and inspection reports?
These can be requested with your order. State the material-document type, traceability needs, critical dimensions, sampling and report format before ordering so the documentation scope can be confirmed.
How quickly can you manufacture and deliver parts?
Your quotation confirms the proposed manufacturing schedule after drawing and material review. Stock availability, part complexity, quantity, finishing and inspection affect lead time. Include your required date and shipping destination with the RFQ.
