Custom CNC Machining Services

A STEP, STP or Parasolid model plus a PDF drawing is the strongest RFQ package. The model defines nominal geometry; the drawing communicates tolerances, GD&T, threads, material, surface finish, cosmetic zones and inspection requirements. Include quantities, target delivery and required quality records.

Yes. Custom CNC machining can support one-off prototypes, bridge quantities and repeat production. Quantity affects stock purchasing, programming, fixtures, inspection sampling and unit cost, so share both the immediate order and expected repeat demand where possible.

Tolerance capability is feature-specific rather than a blanket value for an entire part. Selected features may be reviewed down to ±0.005 mm, depending on part size, geometry, material, setup, thermal stability and the agreed inspection method. The approved quotation and drawing control the final requirement.

Use 5-axis machining when compound angles, continuous contours, deep access, short-tool requirements or critical relationships across several faces create measurable value. Accessible prismatic parts are often more economical on 3-axis equipment, while indexed 3+2 machining can reduce fixtures without requiring simultaneous motion.

Common options include aluminum, stainless steel, tool and mild steels, titanium, brass, bronze and copper, plus ABS, nylon, polycarbonate, acetal, PEEK, PTFE and acrylic. Exact grade, temper, product form, certification and availability are confirmed during review.

Options include as-machined, bead blasted, polished or brushed, anodized, passivated, plated, painted and powder coated finishes. Compatibility depends on the exact substrate. Coating thickness, masking, threads, fits, cosmetic zones, color and texture should be defined before production.

The main drivers are material and stock size, removed volume, machine cycle time, tool access, setup and fixture count, tolerance and inspection scope, quantity, finishing, certification, packaging and delivery. Cost falls most safely when non-functional complexity is removed while functional interfaces remain protected.

Use the largest practical internal radii, avoid unnecessarily deep cavities, standardize holes and threads, limit tight tolerances and fine roughness to functional surfaces, keep features accessible from fewer setups, and identify cosmetic finishing only where it is visible or required.

They can be reviewed, but capability depends on material, unsupported length, tool reach, access and tolerance. Thin walls may move during cutting; deep pockets require longer, less rigid tools; and complex geometry may need 3+2 or 5-axis machining. Share the functional reason for the feature so engineering can recommend a practical route.

Project-specific options can include dimensional inspection reports, first-article records, CMM data, material certificates and finish documentation. Required records, sampling level and acceptance criteria should be stated in the RFQ so they are included in the quoted route.

Timing depends on part count, geometry, materials, tolerance complexity, finishing and documentation requirements. After the files are reviewed, Mockup confirms open questions, the expected quotation timing and whether additional engineering review is required.
