Economical CNC engraving machine

1. Engraving machine designed for different applications, the required performance of the CNC engraving machine is not the same. The CNC engraving machine is designed to use the MACH software and PC parallel port of the existing resources, to provide a low-cost, efficient and practical CNC engraving system solutions, to lower the price of carving machine. The machine can be carved wood, organic glass, PVC board, crystal, copper and aluminum materials, also can be carved in the circuit board processing, etc. , to meet different needs. 2. Engraving machine engraving machine main parameters design effective stroke, 50 mm * 240 mm * 400 mm; Engraving machine precision, 0. 05mm; Repositioning precision engraving machine, 0. 02mm； The spindle speed, 8000 ~ 15000 r/min; Largest feed speed, 3 m/min, the transmission system X, Y, Z adopts stepper motor drive, stepper motor driver with 8 subdivision driver; Resolution, 0. 0025 mm, the use of open loop control. 3. Computer engraving machine system the composition of computer engraving machine a complete work process mainly includes four parts. Part 1, embossed design and the G code generation, such as common ARTCAM software, the software can complete 3 d relief manufacture and the G code generation, and has function of knife road simulation process, can truly simulate the shape of the processing path and the product. Part 2, the distribution of the pulse and to send, the role of the MACH software is similar to the movement control CARDS, main effect is to complete the interpretation of the G code, to be the displacement of the coordinate calculation, decoding, knife repairing, interpolation, deceleration control and the axial displacement of the pulses sent. Part 3, the role of the control system is mainly to complete the various axial pulse spacing, the origin switch during the process of sending and receiving signals to the MACH control software, at the same time to drive each axis movement. Part 4, carving machine body through the transmission mechanism of the movement, the complete material carving action with knives, eventually forming processing products.
