CUSTOM CNC MILLING
Custom metal and engineering plastic parts, from prototypes to production. Get the milling, finishing and inspection your drawing requires through one point of contact.
From flat mounting surfaces to open pockets and threaded holes, we plan the machining around your part's geometry and assembly requirements. Related process guides explain CNC drilling and CNC boring when planning holes and finished bores.
Face milling, contours, steps, open cavities and slots for plates, brackets and equipment components.
Plates · Brackets · Fixture bodiesDrilling, boring and tapping, with hole sizes, spacing and functional requirements reviewed against the drawing.
Mounting holes · Bores · ThreadsRepositioning and fixtures for accessible features on additional faces, with datum relationships considered from the start.
Workholding · Datums · Tool accessSpecify the dimensions that matter. Tolerances depend on material, feature size and part geometry. Surface roughness depends on material, part geometry and machining conditions. Mark critical fits, geometric tolerances and required surfaces on your drawing.

Three factory part photographs show the types of geometry suited to CNC milling. Explore an illustrative specification for each.
01PROFILE / SLOTS / HOLES
Profile milling and drilling with attention to hole spacing, consistent thickness and clean mounting edges.
02POCKETS / STEPS / BORES
Open-pocket milling with a central island. Tool access, internal radii and pocket depth guide the machining plan.
03CONTOURS / MOUNTING HOLES
Contour milling and drilling for an open frame, with workholding planned to support its arms and mounting features.

Need help matching material, geometry and finish?
Explore Our MaterialsComplete your machined part with a finish selected for its material, appearance and functional requirements.
Anodizing or hard anodizing for suitable grades.
Passivation and suitable mechanical finishes.
Zinc plating, black oxide or suitable nickel plating.
Finishing compatibility varies by material and grade. Other combinations, including plastic parts, are reviewed individually.
05 / EQUIPMENT & QUALITY
Vertical and gantry machining centers support the production route. Inspection is planned around your part's functional dimensions.
YSMV-1517 gantry machining is also available. Part size and fixture clearance are confirmed during drawing review.
INSPECTION THAT FOLLOWS THE DRAWING
CMM, optical measurement and height gauges support incoming, first-article, in-process and final checks.
Confirm report requirements with your quotation.
A clear sequence. Defined checks at each stage.
Check the drawing revision, material, functional dimensions and finish.
Define the machining route, datum scheme, fixtures and tool access.
Set up the part and inspect the first article before batch production.
Machine the batch with in-process checks and agreed finishing.
Complete final checks, protect the parts and prepare them for shipment.
Samples: 3–5 working daysBatches: 7–15 working days
Final timing depends on material, quantity, complexity, finishing and inspection. Transit time is separate.
Three decisions that help align your drawing with a practical machining route.
Identify mating surfaces, assembly holes and functional dimensions. Apply tighter tolerances where the part needs them.
Discuss Your DrawingDeep pockets, narrow slots and small internal radii influence tool reach, cutting stability and cycle time.
Review Internal Corner RadiiConsider setup count, material, quantity, finishing and inspection together when reviewing machining cost.

Plates, brackets, open pockets, slots, drilled features and tool-accessible surfaces are common candidates. Features on multiple faces may need additional setups. We review the drawing to determine a suitable machining route.
Dimensional tolerances are typically ±0.05–±0.10 mm, depending on material, feature size and part geometry. Surface roughness is Ra 0.8–6.3 μm, depending on material, part geometry and machining conditions. Mark critical dimensions, geometric tolerances and required surfaces on the drawing for review.
Yes. Material options include aluminum, stainless steel, carbon and alloy steel, brass, copper, titanium, tool steel and engineering plastics such as POM, nylon, PEEK and PEI. Specify the grade and condition when requesting a quote.
Yes. We provide machining and surface finishing through one point of contact. Options include anodizing, hard anodizing, bead blasting, polishing, brushing, passivation, electroless nickel plating, zinc plating, powder coating and black oxide. Availability depends on material compatibility and part requirements.
Three-axis machining is a strong candidate when cutting tools can reach the required features with practical setups. Angled features, complex surfaces or demanding relationships between faces may benefit from a different approach. We assess access, setup count and total cost against your drawing.
Reference production windows are 3–5 working days for samples and 7–15 working days for batches.
