VMC 1160 vertical machining center, in the standard configuration state, the feed axis is x, y and Z three coordinate three linkage control. It can realize the machining of various complex parts such as discs, plates, shells, cams and molds in one clamping, such as drilling, milling, boring, expanding and reaming. Equipped with the fourth axis CNC dividing head or rotary table, it can process more complex parts such as spiral groove on the rotary body.
The line rail is rolling friction, point or line contact, the contact surface is small, and the friction force is also small. It is mainly used in machining with small cutting amount and fast cutting. Features: high speed and high precision, convenient maintenance in the later period.
The hard gauge belongs to the surface contact, the contact surface is large, the friction force is large, and the speed of rapid movement is slow. When machining cast iron and steel castings, the cutting amount is large, the cutting force is relatively large, and the vibration is relatively severe. At this time, the benefits of hard rails are It appears, because the hard rail surface is in contact with the surface, the contact surface is large, and the shock absorption is better, which can not only ensure the processing efficiency but also ensure the processing accuracy. The hard rail is the traditional machine tool rail, which is usually a rail made of cast iron or steel after quenching and grinding.
When machining cast workpieces, hard rails are better, especially when roughing and finishing are done together. If only finish machining is done, the line rail is good, and the line rail moves quickly, which can save non-processing time in mass processing.
