Understanding CNC Machining

CNC (Computer Numerical Control) machining is a prevalent manufacturing process that uses automated, high-speed cutting tools to remove material from metal or plastic workpieces to achieve precise geometries. Common CNC machines include 3-axis, 4-axis, and 5-axis milling machines, lathes, and routers. The machining process can vary based on whether the workpiece or the cutting tool is moved.

Upon receiving a CAD (Computer-Aided Design) model or 3D file, machinists program tool paths to optimize efficiency and achieve tight tolerances. CNC machines can handle a variety of materials, including metal alloys, plastics, wood, stone, and ceramics. GCH offers machining services across a broad spectrum of materials, from standard aluminum and steel to advanced titanium and engineered plastics.

GCH CNC Machining Capabilities

GCH is equipped to tackle tight tolerances and complex parts with precision. Here’s a closer look at our CNC machining services:

• CNC Milling: Our 32 sets of 5-axis CNC milling machines enable us to mill complex plastic and metal parts with tight tolerances efficiently. We also provide cost-effective solutions using 3- and 4-axis milling machines.
• CNC Turning: Ideal for producing round components like worm shafts, CNC turning, combined with live tooling, can achieve complex geometries.
• EDM & Wire-Cut: This process uses specialized tools like copper, graphite, or molybdenum wire to create sharp corners, undercuts, and detailed features. EDM is also used for rapid tooling and mold production.
• CNC Grinding: For parts requiring ultra-flat surfaces or precise tolerances, such as OD and ID +/- 0.005mm, our CNC grinding services are the perfect solution.
• Swiss Machining: Efficient for producing complex or slender components, Swiss machining moves both live tooling and the workpiece to prevent deformation.
• CNC Routing: In addition to standard milling, we offer CNC routing for prototypes and parts made from soft materials like EPS foam, EVA, and wood.

Production Capacity and Standards

With over 50 CNC machines and ISO 9001:2015 certification, GCH produces over 10,000 CNC parts monthly. We work with more than 100 materials, including both plastics and metals. Our quality assurance process includes detailed inspections to ensure that all parts adhere to your specifications.

Material and Finish Options

GCH provides a diverse range of materials and surface finishes to meet your needs. From standard materials like ABS and stainless steel to advanced options like PEEK and Inconel, we offer numerous choices for your projects. Our surface finish options include bead blasting, anodizing, chroming, and more.

Design Guidelines for CNC Machining

When designing parts for CNC machining, consider the following:

• Part Size: Machine envelope limits size. Multi-axis machines typically accommodate larger parts than 3-axis machines.
• Feature Alignment: Align features on a single face to reduce costs.
• Fillets: Use large fillet radii to avoid tool damage.
• Wall Thickness: Minimum thicknesses are 0.8 mm for metals and 1.5 mm for plastics.
• Cavity Depth: Limit depth to 4x the width to prevent issues.
• Holes and Threads: Ensure diameters correspond to standard tools, and depth is no more than 10x the diameter.
• Undercuts: Use standard angles for T-slot and dovetail undercuts.

From Concept to Production

CNC machining is ideal for producing both prototypes and large production runs. At GCH, we offer:

• Prototype Machining: Quick turnaround times for design verification.
• Low-Volume Machining: Cost-effective solutions for small to medium quantities.
• Production Machining: Efficient large-scale production with consistent quality.
