Features of CNC engraving and milling machine

1. The volume of the machining centre is larger than that of the engraving and milling machine.

2. Machining centres usually use cantilever, engraving and milling machine and engraving machine more gantry structure, gantry type is divided into beam and fixed beam, engraving and milling machine for the fixed beam type.

3. Machining centre spindle turns 8000-12000; spindle speed skeletonising machine is the most common 240 000, high-speed machine at least 30,000 turns; engraving machine is usually the same as the skeletonising machine, used for high-gloss processing engraving machine can reach 100,000 turns, but not the usual electric spindle with the spindle but flotation.

4. Spindle for power: processing technology centre can be the largest, from a few kilowatts to dozens of kilowatts between there; carving and milling machine is second, usually within ten kilowatts; engraving machine is the smallest.

5. Cutting volume: the largest, especially suitable for heavy cutting, roughing processing centre; milling machine carving time, appropriate finishing; the smallest engraving machine.

6. Processing technology centre can be used to complete a larger impact on the milling volume of the workpiece processing production equipment, large-scale moulds, hardness for the comparison of materials, but also suitable for ordinary moulds to open the rough; carving and milling machine for the completion of a number of smaller milling volume, small moulds, suitable for copper, graphite, etc.; processing.

Low-end engraving machine is inclined to use wood, two-colour plate, acrylic plate and other hardness requirements are not high plate information processing, high-end suitable for wafers, metal materials such as shell polishing and grinding.
