FAQ

How do you prevent overcutting on complex geometries in my parts?

To avoid overcutting in complex parts, we implement the following proven strategies:

Tool Selection: Use short, rigid tools with large diameters to minimize vibration. Carbide tools with optimized spiral angles (30°–45° for aluminum, 15°–25° for steel) reduce cutting forces

 

Programming Tactics:

  1. Apply climb milling for stable cutting conditions.
  2. Add corner-clearing routines and uniform stock allowances (0.2–0.5mm).

Parameter Control: Limit stepovers to <50% tool diameter and adjust feed rates using machine SF functions

 

Quality Checks: Perform 100% CMM inspection on critical features.

How do you handle warping in thin-walled stainless steel parts?

Thin-walled stainless steel components (e.g., aerospace ducts, medical implants) require precision warping control. Here’s our engineered approach integrating ​thermal dynamics, ​structural optimization, and ​industry certifications, optimized for keywords like thin-walled stainless steel warping preventionCNC machining distortion control, and aerospace-grade stainless fabrication.

1. Process Parameter Optimization

 
ParameterStainless 316LStainless 304Duplex 2205
Cutting Speed (m/min)60–9070–10050–80
Feed per Tooth (mm)0.04–0.060.05–0.080.03–0.05
Clamping Force (N)200–400150–350250–500
 
  • Axial Fixturing: Custom mandrels with 0.005mm concentricity tolerance eliminate radial deformation risks.
  • Multi-Stage Roughing: 3-step material removal (1mm → 0.5mm → 0.2mm) with cryogenic cooling between stages
 

2. Thermal Stress Mitigation

  • Laser-Assisted Machining: Pre-heat localized zones to 150–200°C using 1kW fiber lasers, reducing thermal gradients by 40%
  • In-Process Cooling: High-pressure coolant (70 bar) targeting tool-workpiece interface lowers cutting temps to <120°C

3. Structural Reinforcement

  • Topology-Designed Jigs: Additive-manufactured titanium fixtures with lattice structures provide 360° support for parts with 0.5mm wall thickness
  • Residual Stress Mapping: Use XRD (X-ray diffraction) to identify high-stress zones (>500 MPa) for targeted stress-relief annealing

4. Post-Machining Correction

  • Peening Techniques: Laser peening (3–5GW/cm² pulses) induces compressive stresses up to 800MPa, counteracting warping
  • Hydroforming Adjustment: Apply 200–300MPa hydraulic pressure to reshape deformed areas within ±0.1mm tolerance.

Can you ship directly to my overseas factory?

Yes, we offer direct shipping to overseas factories. Our logistics partners include DHL, FedEx, and trusted sea freight providers. Typical delivery times:

  • Air Freight: 5–7 business days to the US/EU.
  • Sea Freight: 20–30 days for large batches.

All shipments include customs documentation and real-time tracking.

How to reduce CNC costs without sacrificing quality?

Achieving cost efficiency in CNC machining without compromising quality demands a holistic approach integrating ​design intelligence, ​material science, and ​process optimization. Below are actionable strategies aligned with SEO keywords like CNC cost reduction strategiesprecision CNC machining optimization, and low-cost CNC prototyping.

1. Design for Manufacturability (DFM)

  • Internal Radius Optimization: Add radii ≥1/3 of cavity depth to enable larger tools (e.g., ø8mm end mills), reducing machining time by 20%
  • Thin-Wall Avoidance: Maintain wall thickness >0.8mm (metal) or 1.5mm (plastic) to prevent tool deflection and scrap
  • Feature Consolidation: Merge multiple components into single setups (e.g., 3-in-1 brackets) to eliminate assembly costs

2. Material Cost Engineering

MaterialCost-Saving AlternativeStrength Retention
316L Stainless Steel304 Stainless Steel85% yield strength
Titanium Grade 5Aluminum 707570% strength-to-weight
Brass C360Free-Machining Steel 12L14Comparable machinability

Bulk Purchasing: Partner with suppliers for discounted rates on common alloys (e.g., aluminum 6061)

3. Process Efficiency Tactics

  • Adaptive Machining: Use trochoidal toolpaths to reduce tool wear by 30% and cycle times by 25%
  • Multi-Axis Optimization: 5-axis machines produce complex parts in single setups, cutting labor costs by 40%

4. Tolerance Tiering

Feature TypeRecommended ToleranceCost Impact
Functional Surfaces±0.005mmHigh (CMM inspection)
Non-Critical Holes±0.1mmLow (Standard tools)

GD&T Implementation: Apply geometric tolerancing to avoid over-specification

5. Supply Chain Synergy

  • Localized Sourcing: Reduce lead times and shipping costs by collaborating with regional material vendors
  • Digital Prototyping: Use AI-driven CAM software (e.g., Fusion 360) to simulate machining and prevent errors pre-production

Can you anodize parts in custom colors?

Yes, we offer custom color anodizing services for CNC-machined parts. By adjusting the type of dyes, electrolytic solutions, and process parameters (e.g., voltage, temperature, and immersion time), we can achieve a wide range of colors, including ​gold, red, black, blue, green, and bronze, to meet specific design requirements

For example:
  • Architectural Applications: Custom gold or bronze finishes for luxury buildings
  • Industrial Components: Black or gray coatings for corrosion resistance in automotive parts
  • Consumer Electronics: Vibrant colors like blue or red for aesthetic appeal
We ensure color consistency through strict control of dye batches, process parameters, and post-anodizing quality checks

What to do if unsatisfied with surface treatment results?

If you're unsatisfied with surface treatment results (e.g., anodizing,shot peening, or chemical film, take these steps:

Review Design Specifications: Confirm the original requirements (e.g., color codes, roughness Ra values) match the treatment process

Supplier Communication: Provide photos and CMM reports to your manufacturer for root-cause analysis

Rework Options:

  • For uneven anodizing: Strip the coating chemically (e.g., NaOH solution) and re-anodize with adjusted dye batches
  • For shot peening defects: Re-blast using finer media (e.g., glass beads instead of steel grit)

Quality Guarantees: Reputable suppliers often offer free rework or refunds for non-conforming finishes
