CNC Machining Services for Prototypes & Batch Production
FIWOK provides build-to-print CNC machining for prototype and batch production parts. Submit your CAD files and drawings for review, and we will assess manufacturing requirements such as material, tolerances, finishes, quantity, documentation, and delivery needs during quotation and engineering review.
Core CNC Machining Services
Explore CNC milling, CNC turning, and Swiss-type machining options for different part geometries and production requirements. The appropriate process is reviewed based on the part design, material, tolerances, quantity, finishing, and documentation needs.
CNC Milling
CNC milling can support parts with pockets, holes, multi-face features, and selected complex geometries. Three-, four-, and five-axis approaches are reviewed according to part design, material, tolerances, and production requirements.
CNC Turning
CNC turning is suited to parts with cylindrical or concentric features, including shafts, threaded components, and selected turned-and-milled parts. Process planning is reviewed according to geometry, material, quantity, and tolerance requirements.
Swiss-Type Turning
Swiss-type machining can support selected small-diameter, slender, and complex turned parts. The guide-bushing process may help support long, narrow workpieces, while achievable tolerances and surface requirements are reviewed by project.
Support for Buyers & Engineering Teams
Our quotation and engineering review process helps clarify manufacturing requirements, support technical communication, and align project expectations before production.
From Prototype to Production
We can support prototype, low-volume, and selected production orders as project requirements develop. Manufacturing planning is reviewed according to part requirements and available capacity.
Drawing-Based Manufacturing
Manufacturing is performed based on approved drawings, specifications, and agreed project requirements. Critical dimensions, tolerances, finishes, and inspection needs are reviewed by project.
Technical Communication & DFM Review
Our team can support technical communication during quotation and engineering review. Depending on project scope, we may discuss feature feasibility, tool access, and tolerance considerations before production.
Materials and Finishing Options
Review commonly requested material and finishing options for CNC-machined parts. Material availability, finishing processes, specifications, documentation, and dimensional considerations are confirmed during quotation and engineering review.
Common Material Options
- Aluminum Alloys: 6061, 7075, and 5052 options may be reviewed for weight, strength, corrosion, and formability requirements.
- Stainless Steels: 303, 304, 316, and 17-4 PH options may be considered based on corrosion, strength, machinability, and project requirements.
- Carbon & Alloy Steels: 1018, 1045, and 4140 may be reviewed for general machining, structural parts, shafts, and selected strength requirements.
- Copper & Brass: C101 copper and C360 brass may be considered for conductivity, thermal performance, machinability, or hardware applications.
- Engineering Plastics: POM, Nylon, PEEK, PC, and PTFE options may be reviewed based on mechanical, thermal, electrical, chemical, and wear requirements.
Finishing & Surface Treatment Options
- Anodizing (Type II & III): Available for applicable aluminum parts. Coating type, color, thickness, masking, and dimensional effects are reviewed by project.
- Passivation & Chemical Conversion: Passivation may be used for applicable stainless-steel parts, while chemical conversion coatings may be considered for aluminum parts.
- Bead Blasting & Brushing: Bead blasting can create a matte texture, while brushing produces a directional satin finish. Masking needs are reviewed where required.
- Plating Options: Nickel, zinc, and other plating systems may be reviewed for corrosion, wear, conductivity, appearance, or functional requirements.
- Powder Coating & Painting: Colored coating options may be considered for cosmetic appearance and additional environmental protection. Thickness and masking requirements are reviewed by project.
- Laser Marking: Part numbers, logos, and identification codes may be added where compatible with the material, finish, artwork, and marking-location requirements.
Quality Verification Activities
Quality verification activities are planned according to part requirements, agreed inspection scope, and documentation needs. Material review, in-process checks, final inspection, and requested records may be included as applicable to the project.
Material Review
Incoming material information may be reviewed against project requirements and available supplier documentation, including MTRs when requested.
In-Process Verification
Selected dimensions, datums, and process checkpoints may be reviewed during production according to the agreed inspection plan.
Final Inspection
Final inspection may include dimensional, visual, and documentation checks based on agreed drawing and inspection requirements. CMM or VMS measurement may be used where specified.
Documentation Options
MTRs, CoCs, inspection reports, and traceability records may be available when requested and confirmed during quotation or order review.
Representative Machined Components
Explore representative component types that can be reviewed for CNC milling, turning, and Swiss-type machining. Material, process, tolerances, finishing, and inspection requirements are assessed according to each project.
Milled Aluminum Housings
6061-T6 aluminum housings and enclosures can be machined with pockets, mounting features, and multi-face geometry. Anodizing, dimensional requirements, and assembly-related features are reviewed according to the project.
CNC Turned Shafts & Fasteners
CNC turning can support shafts, pins, threaded hardware, and other parts with cylindrical or concentric features. Material, quantity, tolerance, and secondary-operation requirements are reviewed during quotation.
Swiss-Type Pins & Small Turned Parts
Swiss-type machining can support selected small-diameter, slender, and detailed turned components. Process selection, tolerances, surface requirements, and inspection scope are reviewed according to the part design and project needs.
CNC Machining RFQ FAQs
What are your lead times and minimum order quantities (MOQs)?
Lead times vary based on part complexity, material availability, quantity, finishing requirements, and current production capacity. We support low-volume and single-part requests where feasible; larger projects receive a production schedule during quotation.
How do you determine the manufacturing process for my part?
We review part geometry, feature access, material, tolerances, quantity, and finishing requirements during quotation and engineering assessment. Milling, turning, Swiss-type machining, or a combined approach may be considered based on project requirements.
What information is needed for a quote?
Please provide a 3D CAD file, when available, and a current 2D PDF drawing identifying critical dimensions and tolerances. Material grade, quantity, finish requirements, target delivery date, and requested documentation also support an efficient quotation review.
How do you manage tight-tolerance and repeat-order requirements?
Tight-tolerance features are reviewed according to part geometry, material, machining strategy, and inspection requirements. For repeat orders, production and inspection requirements can be reviewed against the approved drawing, order details, and confirmed process controls.
Can material certificates and inspection reports be provided?
MTRs, CoCs, inspection reports, and other documentation may be available when requested and confirmed in the quotation or purchase-order scope. Please identify required standards, report formats, and inspection requirements in your RFQ.
How do you handle design confidentiality?
Customer drawings, CAD files, and project information are treated as confidential and used for quotation, engineering review, and manufacturing purposes. If required, we can review a mutually acceptable NDA before detailed technical information is exchanged.
