Introduction A machine tool is a processing machinery, typically used to manufacture and fabricate various kinds of devices and machine parts, which is known as the “mother of machinery”, also called “machining center”. Generally speaking, a machine tool can be powered by a variety of sources. When machine tool powers on, it is able to move solid materials and perform various operations such as cutting, milling and drilling, etc. by physical and chemical force or other methods. In the cutting process of computed numerically controlled (CNC) machine tools, a high level processing precision is essential.
A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
1.Introduction Plastic extruders are also one of the types of plastic machinery. The extruders can be divided into the right angle head, the bevel head and others according to the angle between the materials flow direction of the head and the screw center line. The outer casing of the head is generally fixed on the fuselage by bolts. The mold inside the head contains a core holder, then using the nut to fix it in the inlet port of the head, and the inside of the core holder is also installed the core. The wires can pass the core and core holder since they have holes in the certer. Depending on the types of pressurization method, the extrusion process can be divided into continuous extrusion and intermittent extrusion. The equipment used in the former is a screw extruder, and the latter is a ram extruder. In this case, the screw extruder can be roughly classified into a single screw extruder and a multi-screw extruder by the number of screws.
