Metal CNC machining is a precision manufacturing process that involves cutting raw metal to achieve desired shapes or objects. Guided by CAD (Computer Aided Design) software, CNC (Computerized Numerical Control) machines—primarily 3-axis and 5-axis models at HLW—deliver exceptional accuracy and tight tolerances, even for complex part geometries. Key processes include CNC metal milling, where precision cutting tools mounted on high-speed rotating spindles remove material from raw blocks or sheets, and CNC turning for more complex machining jobs. The versatility of these machines allows for the production of nearly any 3D component that can be represented in a CAD file, with 5-axis CNC milling machines capable of handling the most intricate designs.

HLW’s CNC metal fabrication process excels at creating shapes from single pieces of metal, analogous to carving a surfboard from wood but with metal, drills, and computerized precision. Through its extensive supplier network, HLW has access to over 1,600 metal milling and turning machines, ensuring consistent capacity, competitive pricing, and fast turnaround times. The company caters to both low-volume orders and complex machining requirements, offering various surface finish options. For cost estimation, HLW utilizes machine learning algorithms trained on millions of previous orders to generate instant quotes directly from CAD files. Additionally, HLW provides vapor polishing for polycarbonate (via manual request) and manual polishing for acrylic.
