Surface treatment of CNC customized parts

Enhance the appearance, performance, and longevity of your turned parts with our comprehensive range of surface finishes.

As-Machined (Standard) ›⌄

A standard finish straight off the machine, with typical surface roughness (Ra) of 3.2 μm. Ideal for non-critical internal components.
Bead Blasting ›⌄

Creates a uniform, matte, or satin surface texture that hides tool marks and provides a clean, non-reflective appearance.

What Is Custom CNC Machining? A Clear, Practical Guide for Engineers Designers

A comprehensive overview of our custom CNC machining capabilities—from subtractive manufacturing principles and multi-axis processes to material selection and design optimization.

Definition and Basic Process

Custom CNC Machining is an advanced subtractive manufacturing process that transforms solid blocks of metal, plastic, or composite materials into precision parts. Unlike standard mass production, our custom service tailors every tool path, material specification, and surface finish to meet the unique geometric, functional, and performance requirements of your project.

How CNC Turning Works

Your design files (STEP, IGES, etc.) are imported into our CAD/CAM software, where our engineers generate toolpaths optimized for efficiency and precision. Our state-of-the-art CNC equipment—including multi-axis lathes, milling centers, and Swiss-type machines—removes excess material with micron-level accuracy, crafting complex 3D geometries, tight tolerance features, and custom profiles exactly as specified in your drawing.

Our CNC Equipment Capabilities

● CNC Lathes (Horizontal Swiss-type): Ideal for high-precision cylindrical parts, shafts, bushings, and complex rotational components.

● 3-Axis 5-Axis Milling Centers: Perfect for complex non-circular shapes, pockets, slots, and undercuts that demand multi-sided machining.

● Multi-Axis Combined Centers: Handling the most intricate geometries in a single setup for unmatched efficiency and accuracy.

Turning vs. Milling: When to Choose Custom CNC?

CNC Turning (Lathes): Best for rotational symmetry (round parts, shafts, sleeves). The workpiece rotates while the tool cuts, excelling at precision cylindrical features.

CNC Milling: Best for complex 3D shapes, flat surfaces, pockets, and slots. The cutting tool rotates while the workpiece moves, ideal for irregular, non-circular components.

Our Advantage: We provide both services under one roof, offering a true one-stop solution for parts that require both rotational and complex 3D features.
