Computer Engraving Machines and Their Joint Applications with CNC Milling Machines and Machining Centers

CNC computer engraving machine in recent years in the domestic development, in foreign countries have long had the noun (CNC Engraving and Milling Machine). Strictly speaking, carving is a part of milling, the traditional CNC milling machine, CNC processing center power, high processing efficiency, machine tool stability is better, but the processing of copper, aluminum and other soft materials, there is a low finish of the processing surface, processing efficiency is not high shortcomings, and high-speed CNC processing center although can overcome the above shortcomings, but expensive, the general manufacturers can not bear. Compared with the traditional CNC equipment, CNC computer engraving machine has the advantages of high speed, high efficiency of processing soft materials, high surface finish and high cost-effectiveness.

The mechanical part of the CNC computer engraving machine compared with the CNC milling and processing center.

The machinery of general machine tools is generally divided into two parts: the moving part and the non-moving part, the work table, the spindle skateboard, etc. are the moving part, the bed body, the base, the column, etc. are the non-moving part.

1. CNC milling, CNC processing center.

CNC milling, the non-moving part of the CNC machining center, and the rigidity of the moving part are all very demanding and therefore can be re-cut. But because the moving part is equally large, at the expense of machine flexibility, it is difficult for small cuts and fast forwarding.

2.CNC computer carving milling machine.

The non-moving part rigidity requirements of the carving mill should also be as good as possible, while the rigidity of the moving part should be flexible as the front question, to be designed as light as possible, while maintaining a certain degree of rigidity. In this way, the design of CNC computer engraving machine can be relatively small finishing, processing accuracy is high, for soft metal can be high-speed processing, but because the rigidity of the moving part is poor, so it is not possible to re-cut. So how to solve the contradiction of moving part weight light, rigid and good from the mechanical structure, the key lies in the mechanical structure of kung fu. Here's how:

Designed with ultra-wide columns and beams, the gyro-style structure has excellent symmetry and excellent rigidity, and is the preferred structure for high-speed cutting equipment. Compared with the traditional C-shaped bed body structure, the bed body rigidity in the form of a dragon gate frame is high, the force average, the work piece only moves in one axial direction, the movement axis and relative inertia are low, the design is compact and precise, ensuring high rigidity, high precision and high dynamic characteristics. The cross-beam of the machine can be tilted 30 degrees structure, so that the center of gravity of the spindle saddle moves back, and make the rail spacing of the cross-beam as much as possible, thus greatly improving the stability and rigidity of the spindle. Since the quality of the column is much greater than that of moving parts such as spindles, it provides a solid guarantee for the high-speed movement of the machine and the high-speed operation and load cutting of the spindles.
