Engraving machine: It has a high spindle speed, which is suitable for processing small tools. It has a relatively small torque and focuses on the "engraving" function. For example, it can process wood (specialized wood carving machines are called wood carving machines), two-color boards, acrylic boards and other boards with low hardness. It is not suitable for large workpieces with strong cutting. At present, most products on the market that are called engraving machines are mainly for processing handicrafts. They are low-cost and not suitable for mold development due to their low precision. However, there are exceptions such as wafer engraving machines.
Engraving and milling machine: As the name suggests. It can be engraved or milled. On the basis of the engraving machine, the spindle and servo motor power are increased, the bed bearing capacity is increased, and the spindle speed is maintained. More importantly, the precision is very high. The engraving and milling machine is also developing towards high speed, generally called a high-speed machine, with stronger cutting ability and very high processing precision. It can also directly process materials with a hardness of more than HRC60 and form them in one go.
In terms of appearance and volume, machining centers are the largest, with the large 1690 model measuring 4m*3m and the small 850 model measuring 2.5m*2.5m; milling machines are the second largest, with the larger 750 model measuring 2.2m*2m; and engraving machines are the smallest. In terms of mechanical structure, machining centers generally use cantilever type, while milling and engraving machines generally use gantry type structures, which are divided into beam type and fixed beam type. Currently, most milling and engraving machines are fixed beam type. |
