How to distinguish machining center engraving machine and milling machine

Engraving machines and milling machines, engraving machines and machining centers (computer gongs) are very similar in appearance and structure. The following CNC part processing center manufacturers teach you how to distinguish these three:

In terms of appearance and volume, the CNC part machining center has a large volume. The size of the large 1690 machine is 4m × 3m, and the size of the small 850 machine is 2.5m × 2.5m. The engraving machine and milling machine rank second. 750 or more machines are generally 2.2m × 2m; engraving machines are small.

As far as the mechanical structure is concerned, the machining center generally adopts the cantilever type, and the engraving and milling machines and engraving machines generally adopt the gantry type structure. The gantry type is divided into a beam type and a fixed beam type. Currently, most of the engraving and milling machines are fixed beam types.

Engraving machine: high spindle speed, suitable for processing small tools, relatively small torque. It focuses on the "sculpting" function. For example, wood (wood carving machine specially used for processing wood boards), two-color boards, acrylic boards and other lower hardness boards are not suitable for large workpieces with strong cutting strength. At present, most of the products on the market under the banner of engraving machines are mainly processed crafts, which have low cost and low precision, and are not suitable for mold development. However, there are exceptions, such as wafer engraving machines.

Engraving machines and milling machines: as the name implies. It can be carved or milled. On the basis of the engraving machine, increase the power of the spindle and servo motor. The bed can withstand the force while maintaining the high speed of the spindle. More importantly, the accuracy is very high. Engraving machines and milling machines are also developing at high speeds and are often referred to as high-speed machines. They have strong cutting ability and high machining accuracy. They can also directly process materials with hardness above HRC60 and form them in one step.

In terms of application objects, CNC part machining centers are used to process workpieces and materials with large milling volumes, large molds, and high hardness. They are also suitable for opening ordinary molds. The engraving and milling machine is used for finishing small milling amounts and small molds, and is suitable for processing copper and graphite. Low-end engraving machines tend to process low-hardness plates such as wood, two-color plates, and acrylic plates, while high-end engraving machines are suitable for polishing wafers, metal shells, etc.
