How Does CNC Machining Work?
The 3-Step CNC Machining Workflow | From Setup to Finish
Precision Workholding & Setup
CNC machining is an automated subtractive manufacturing process that utilizes computerized controls and specialized cutting tools to subtract material layers from a solid blank to form a finished piece. To ensure absolute dimensional stability, the raw billet is rigidly secured within the machine tool using industrial jigs, fixtures, and advanced work-holding tools. This rigid setup completely eliminates part vibration and movement during high-speed spindle operations.
Multi-Axis CNC Machining Operations
Our facility executes three foundational subtractive techniques depending on your design geometry: drilling, milling, and turning.
CNC Drilling: Utilizes precision drill bits to execute accurate cylindrical holes for mechanical fasteners, pins, or screws.
CNC Milling: Employs a multi-axis rotating cutting tool to carve material from the workpiece across multiple angles and axes for complex shapes.
CNC Turning: Spins the raw material block on a high-speed lathe while stationary cutting tools carve precise concentric features.
Industrial Surface Post-Processing
Post-processing is critical to eliminating micro-defects and ensuring uniform cosmetic appearance from part to part. While CNC machining operations can leave visible tool marks on surfaces, we provide a full suite of surface finishing solutions. We offer bead blasting to smooth away machine lines, custom painting for targeted branding, and anodizing or functional chemical coatings to drastically improve corrosion resistance, surface hardness, and material longevity.

Premium CNC Machining Surface Finishes & Post-Processing Specifications
Enhance the aesthetic appeal, environmental resistance, and mechanical performance of your components. At HLH MODEL, we provide a full suite of industrial post-processing solutions tailored to meet strict regulatory and engineering benchmarks:
Vibratory Tumbling (Deburring)
A highly efficient, batch-based finishing process utilizing vibrating abrasive media to break sharp edges, remove heavy burrs, and smooth out visible cutter tool paths on exterior surfaces. Note: Components exceeding 8” (200mm) typically require manual inspection and hand-deburring vectors to maintain tight geometric tolerances.
Titanium Anodizing (AMS-2488 Type 2)
An advanced electrochemical surface treatment—often termed Tiodize—engineered specifically for biocompatible and lightweight titanium alloys. This non-pigmented process dulls surface shine while substantially boosting fatigue strength, galling resistance, and wear protection.

Stainless Steel Passivation
A critical chemical immersion process that removes free iron from the surface of 200, 300, and 400-series stainless steels, alongside precipitation-hardened (PH) corrosion-resistant alloys. This process leaves a negligible dimensional footprint (approx. 0.0000001”) and fully conforms to ASTM A967, AMS 2700, AMS-QQ-P-35, MIL-STD-171, and ASTM A380 standards.
Industrial Powder Coating
An advanced electrostatic process where dry polymer powder is sprayed uniformly onto a conductive part and heat-cured in an oven. This creates a thick, high-durability barrier against impact, scratches, and harsh chemicals that far outperforms liquid painting. Explore our extensive color matching capabilities in our dedicated powder coating finishes gallery.
Precision Electropolishing
An electrochemical material removal process that systematically cleans, deburrs, and brightens stainless steel components. By stripping away a micro-layer of 0.0001” to 0.0025” of the metal, it dramatically minimizes surface roughness, optimizes hygienic properties, and elevates corrosion resistance in strict compliance with ASTM B912-02.
Protective Zinc Plating
An electroplating treatment that applies a uniform zinc layer across complex or irregular geometries. This functional coating acts as a sacrificial anode to defend ferrous metals from oxidation, flash rusting, and atmospheric wear, meeting all requirements of ASTM B633-15.
