1. Different product varieties:
Machined parts are finished products directly processed by machining centers or lathe equipment from raw materials (such as round steel, iron blocks, etc.). The sheet metal parts are formed by using plates (such as aluminum plates, iron plates, stainless steel plates, checker plates, etc.) to be blanked by LASER or NC machine tools and then bent, punched, tapped by fitters, welded and assembled into sheet metal. pieces.
2. Different production methods:
Sheet metal parts are made by filament power winding, laser cutting, heavy duty machining, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, sheet metal bending, die forging, water jet cutting.
Machined parts are mainly divided into two categories: manual machining and CNC machining. CNC machining includes machining centers, turning and milling centers, wire EDM equipment, thread cutting machines, etc. The vast majority of machine shops use CNC machining technology. Manual processing refers to the method of processing various materials by manual operation of mechanical equipment such as milling machines, lathes, drilling machines and sawing machines by mechanical workers.
