huvudbearbetningen
Huvudbearbetningen is a term used in Swedish manufacturing to describe the primary roughing phase of a production process. It designates the main subtractive operations that transform a raw workpiece toward its final geometry, typically removing the largest amounts of material and establishing critical dimensions and features before secondary finishing operations. The scope of huvudbearbetningen varies by industry and product, but common activities include turning, milling, drilling, boring, reaming, and partial grinding. In metalworking, it is usually carried out on CNC machines or conventional lathes and milling machines, using dedicated fixtures to ensure concentricity, perpendicularity, and surface integrity. In plastic or composite production, similar roughing steps are performed with appropriate cutting tools and parameters. The process is followed by finishing operations such as precision grinding, honing, or polishing to meet final tolerances and surface finish.
Quality control is integrated through dimensional inspection, process capability studies, and documentation. Tools include calipers, micrometers,
Because huvudbearbetningen is a general term, its exact meaning depends on the production route, component design,
