Machining is an important process in the production of workpieces. It involves processing materials such as metal and plastic by milling or turning. Milling is where the workpiece is fastened onto a rotating spindle and a milling tool removes material from the surface. Complex shapes and contours can be created by moving the workpiece in different directions. Turning, on the other hand, is where the workpiece is fastened onto a rotating spindle and a cutting tool removes material from the surface. The turning motion allows cylindrical shapes to be produced, such as axles or bolts. Both of these methods require precise machines and trained personnel to achieve high-quality results.
