What is CNC machining?
CNC, or computer numerical control machining, is a widely used manufacturing process that employs automated high-speed cutting tools to remove material from metal or plastic workpieces until the desired geometry is achieved. Standard CNC machines include 3-axis, 4-axis, and 5-axis milling machines, lathes, and routers. CNC machines can cut nearly any material, such as metal alloys, plastics, wood, stone, ceramics, and more. They produce custom machined parts required across virtually all industries, including automotive, robotics, medical, aerospace, electronics, and industrial applications.

Why Choose Us for Custom CNC Machining?
Fast and Reliable Delivery
Iterate part designs quickly and accelerate product development with quick-turn parts. Our automated design analysis will help spot any difficult to machine features before your design is sent to the manufacturing floor and save you from costly reworks further down the product development cycle.
Material Selection
We stock more than 30 engineering-grade plastic and metal materials that are suitable for various part applications and industries. Materials range from plastics like ABS, polycarbonate, nylon, and PEEK to aluminum, stainless steel, platinum, and copper.
Infinite Capacity
Eliminate downtime spent waiting for parts and safeguard in-house machining with on-demand relief and infinite manufacturing capacity.
Advanced Capabilities
Get anodizing, tighter tolerances, and volume pricing options through our network of manufacturers at HLH. You'll find plating (black oxide, nickel), anodizing (Type II, Type III), and chromate coating in larger part quantities; tolerances down to ±0.001 in. (0.020mm); and cost-efficient machined parts at higher volumes to lower piece-part price.
CNC Machining Materials
Copper
Copper is a metal that is corrosion-resistant, extremely electrically conductive, and highly ductile. Its glossy orange-reddish appearance is instantly recognizable, and the metal looks attractive even when it goes through a natural oxidation process that forms a bluish-green coating called patina in response to its environment. Note, however, that copper weldability is considered moderate to poor.
Aluminum
Aluminum is a popular choice for machining due to its low density, good mechanical properties, high thermal and electrical conductivity, and resistance to corrosion. Aluminum alloys, such as 6061-T651, 7075-T651, and 2024-T351, are commonly used in CNC machining because they offer a good balance of strength, machinability, and cost.
ABS
ABS is a low-cost engineering plastic that is easy to machine. ABS is an ideal material for structural applications when impact resistance, strength, and stiffness are required. It’s widely used for pre-production prototypes since it has excellent dimensional stability and is easy to paint and glue.
PVC
Polyvinyl Chloride (PVC) is an extremely versatile polymer and used widely across many industries due to its exceptional corrosion resistance, high strength-to-weight ratio, and cost efficiency.
