CNC Machining FAQs

Quoting & Orders
How do I get a quote?
Upload your 2D drawings and/or 3D CAD files through our quote form and include the required quantity, material, tolerances, surface finish, and delivery requirements. Our team will review the files and prepare a quotation based on the confirmed specifications.
What information should I provide for a quote?
Please provide your CAD files or drawings, quantity, material, surface finish, critical tolerances, and any special inspection or delivery requirements. Complete information helps us quote more accurately and efficiently.
How long does it take to receive a quotation?
We typically review complete RFQs within 24 hours and provide a quotation once the technical requirements are confirmed. Complex parts or projects with special requirements may require additional engineering review.
Can I make changes after receiving a quote?
Yes. If the design, material, quantity, tolerance, surface finish, or other requirements change, send us the updated files or specifications. We will review the changes and update the quotation if necessary.
What payment methods do you accept?
We commonly accept bank transfer (T/T). Other payment methods can be discussed depending on the order. Payment terms will be confirmed in the quotation before production.
CNC Machining
What CNC machining services do you offer?
We provide CNC milling, CNC turning, 5-axis machining, and Swiss machining for custom precision parts. We support prototypes, low-volume production, and small-to-medium production requirements.
Do you support prototypes and low-volume production?
Yes. We support one-off prototypes, engineering samples, and low-volume production for design validation, product development, replacement parts, and specialized equipment.
What types of parts can you machine?
We machine custom non-standard parts including housings, brackets, plates, shafts, fixtures, connectors, and other precision components for industrial equipment and assemblies.
Can you machine complex geometries?
Yes. Depending on the part geometry, we can use multi-axis and 5-axis machining for complex surfaces, deep cavities, multi-angle features, and parts that would otherwise require multiple setups.
What affects the cost of CNC machining?
CNC machining cost is mainly affected by part geometry, material, quantity, tolerance requirements, surface finish, machining time, setup requirements, and inspection requirements. Simplifying non-critical features and avoiding unnecessarily tight tolerances can help reduce cost.
Materials & Finishes
What materials can you machine?
We machine aluminum, stainless steel, tool steel, brass, copper, titanium, and engineering plastics. Specific grades can be reviewed based on your drawing, application, and machining requirements.
Can you help me choose the right material?
Yes. If you are unsure which material is suitable, we can review factors such as strength, weight, corrosion resistance, machinability, cost, and operating environment and suggest suitable options.
What surface finishes do you offer?
Common finishing options include as-machined, bead blasting, polishing, anodizing, nickel plating, and other finishes depending on the material and project requirements.
Can you provide anodizing in different colors?
Yes. Aluminum parts can be anodized in a range of common colors. Exact appearance may vary with alloy, material batch, surface preparation, and anodizing process, so specific color requirements should be confirmed before production.
Can you machine both metal and plastic parts?
Yes. We machine both metals and engineering plastics for custom CNC components. Material selection can be based on strength, weight, wear resistance, electrical insulation, chemical resistance, and application requirements.
Quality & Tolerances
What tolerances can you achieve?
Machining tolerances depend on part size, geometry, material, and feature type. For certain critical features, tolerances down to ±0.005 mm can be achieved after engineering review. Other tolerances are evaluated according to the drawing and inspection requirements.
How do you control part quality?
Quality control includes drawing review, incoming material verification, in-process inspection, dimensional checks, and final inspection before shipment. Critical dimensions and specified requirements are verified according to the approved drawing.
What inspection equipment do you use?
Depending on the part and inspection requirements, we use CMMs, optical measuring equipment, height gauges, micrometers, calipers, thread gauges, and other dimensional inspection tools.
Can you provide inspection reports?
Yes. Dimensional inspection reports can be provided when required. Please specify any reporting or inspection requirements during quotation so they can be included in the inspection plan.
How do you handle parts that do not meet the drawing?
If a non-conformance is identified, the affected parts are reviewed before shipment. Depending on the issue, corrective action may include rework, remake, replacement, or another solution agreed with the customer.
Files & NDA
What CAD file formats do you accept?
We commonly work with STEP/STP, IGES/IGS, Parasolid X_T, STL, DXF, DWG, and PDF files. For CNC machining, a 3D CAD model together with a 2D drawing is recommended when tolerances, threads, surface finishes, or other critical requirements need to be clearly defined.
Should I send both a 3D model and a 2D drawing?
When possible, yes. The 3D model defines the part geometry, while the 2D drawing is useful for specifying tolerances, threads, surface finishes, critical dimensions, GD&T, and inspection requirements.
Are my drawings and project files kept confidential?
Yes. Customer drawings, CAD files, specifications, and project information are treated as confidential and used only for quotation, engineering review, manufacturing, and quality control related to the project.
Can you sign an NDA?
Yes. We can review and sign a non-disclosure agreement when required before confidential project information is shared.
What should I do if my files are too large to upload?
If your files are too large for the quote form, contact us by email and we will arrange an alternative file transfer method.
