4. Process: Precision made.Experience & Reasonable QC that you can reply on Each part would

5. Adequate supply capacity. Punctual delivery time.
Virtually all solid engineering materials, including:
We require a complete 3D CAD model (STEP or IGES format is preferred) along with a detailed 2D drawing. The drawing must specify all critical dimensions, geometric tolerances (GD&T), surface finishes, material specifications, and any special requirements. This combination ensures no ambiguity in the manufacturing intent.
5. What is the difference between prototyping and production machining?
Standard machining tolerances are typically ±0.005 inches (±0.127 mm). For precision components, we can achieve tolerances as tight as ±0.0005 inches (±0.0127 mm) or better, depending on the part geometry, material, and process. Tighter tolerances increase cost, so it's critical to specify them only where functionally necessary.
7. What is "Design for Manufacturability" (DFM) and why is it important?
DFM is the practice of designing parts to optimize them for the machining process. A DFM review by our engineers can identify potential issues (e.g., hard-to-machine features, unnecessary tight tolerances, thin walls) and suggest modifications that reduce cost, shorten lead time, and improve quality without compromising the part's function. We strongly recommend a DFM analysis before production.
8. What surface finishes are available?
As-machined surfaces (Ra 32-125 µin) are standard. We also offer a range of secondary finishing operations:
Yes. For all certified materials (e.g., 6061-T651 aluminum, 304 Stainless), we provide full Material Test Reports (MTRs) or Certificates of Conformity (C of C) from the mill, traceable to the heat/lot number, verifying chemical composition and mechanical properties.
10. What quality control processes do you have?
Our quality management system is integral to our process and includes:
Lead time depends on part complexity, quantity, and current shop capacity.

1. What is machining? What are machined parts?
Machining is a subtractive manufacturing process where material is selectively removed from a solid block (blank) of metal, plastic, or other material to create a precise part. This is done using computer-controlled machine tools like CNC Mills, Lathes, and EDM. The resulting components are called machined parts, known for their high dimensional accuracy, excellent surface finishes, and complex geometric capabilities.
2. What are the main types of machining processes?
- CNC Milling: A rotating cutting tool removes material from a stationary workpiece. Ideal for complex 3D contours, pockets, slots, and flat surfaces.
- CNC Turning: The workpiece rotates while a stationary cutting tool shapes it. Primarily for creating cylindrical, conical, or spherical parts (shafts, pins, bushings).
- Multi-Axis Machining: Combines milling and turning on advanced machines (e.g., 5-axis mills, mill-turn centers) to produce extremely complex parts in a single setup.
- Electrical Discharge Machining (EDM): Uses controlled electrical sparks to erode material, perfect for very hard metals or intricate shapes that cutting tools cannot achieve.
Virtually all solid engineering materials, including:
- Metals: Aluminum (6061, 7075), Steel (Mild, Alloy, Tool Steel), Stainless Steel (303, 304, 316), Brass, Copper, Titanium, Inconel.
- Plastics: Delrin (POM), Nylon, PTFE (n®), PEEK, Acrylic (PMMA), Polycarbonate.
- Other: Composites, graphite, and some ceramics.
We require a complete 3D CAD model (STEP or IGES format is preferred) along with a detailed 2D drawing. The drawing must specify all critical dimensions, geometric tolerances (GD&T), surface finishes, material specifications, and any special requirements. This combination ensures no ambiguity in the manufacturing intent.
5. What is the difference between prototyping and production machining?
- Prototyping: Focuses on speed and flexibility to produce 1-50 parts for form, fit, and function testing. Often uses standard tooling and may involve manual setups, resulting in a higher per-part cost.
- Production Machining: Optimized for efficiency, consistency, and lowest per-part cost at higher volumes (100s to 1000s+). Involves dedicated fixtures, optimized toolpaths, and sometimes custom tooling.
Standard machining tolerances are typically ±0.005 inches (±0.127 mm). For precision components, we can achieve tolerances as tight as ±0.0005 inches (±0.0127 mm) or better, depending on the part geometry, material, and process. Tighter tolerances increase cost, so it's critical to specify them only where functionally necessary.
7. What is "Design for Manufacturability" (DFM) and why is it important?
DFM is the practice of designing parts to optimize them for the machining process. A DFM review by our engineers can identify potential issues (e.g., hard-to-machine features, unnecessary tight tolerances, thin walls) and suggest modifications that reduce cost, shorten lead time, and improve quality without compromising the part's function. We strongly recommend a DFM analysis before production.
8. What surface finishes are available?
As-machined surfaces (Ra 32-125 µin) are standard. We also offer a range of secondary finishing operations:
- Bead/Sand Blasting: For a uniform matte texture.
- Anodizing (for Aluminum): For corrosion resistance and color (Type II or hardcoat Type III).
- Passivation (for Stainless): To enhance corrosion resistance.
- Plating: Nickel, chrome, zinc, or electroless nickel plating.
- Powder Coating or Painting: For durable color and protection.
- Polishing/Buffing: For a high luster, mirror-like finish.
Yes. For all certified materials (e.g., 6061-T651 aluminum, 304 Stainless), we provide full Material Test Reports (MTRs) or Certificates of Conformity (C of C) from the mill, traceable to the heat/lot number, verifying chemical composition and mechanical properties.
10. What quality control processes do you have?
Our quality management system is integral to our process and includes:
- First Article Inspection (FAI): A comprehensive dimensional report per AS9102 or equivalent, verifying the first part matches the drawing.
- In-Process Inspection: Using calibrated equipment like CMMs (Coordinate Measuring Machines), optical comparators, and micrometers to monitor critical dimensions during production.
- Final Inspection: 100% final check or AQL sampling before shipment, with documentation provided.
Lead time depends on part complexity, quantity, and current shop capacity.
- Prototypes: 1-3 weeks.
- Low-Volume Production: 3-6 weeks.
- High-Volume Production: 6+ weeks (often with phased deliveries).
Expedited services are often available for an additional cost.
