What is the difference between a milling machine and an engraving machine?

Engraving machine is mainly used for the carving of the plate, a large number of applications in the two-color plate or acrylic engraving, engraving a feed depth of about 1mm-3mm or so, in the sign, signage applications are more common.

From the mechanical construction, the design of the engraving machine is lightweight, X, Y-axis moving speed, Z-axis stroke is shorter, suitable for engraving 5mm-8mm material. The engraving spindle head is equipped with a spring-loaded pressure nose, which serves to flatten thin plates up to 3mm during the engraving process.

The engraving spindle is connected to a larger diameter motor through a belt, which increases the rotational speed so that the quality of the engraved workpiece is smoother. The carving tool used is longer, with a length of about 15.

9cm in length and 4.35mm in diameter.

Due to design limitations, it is suitable to do cutting volume is very small, high speed carving process production. Carving and milling machine can be understood as both fine engraving, but also can do cutting and skeletonizing.

For example, to do three-dimensional engraving, despite the drop is very large, but 200mm wide material can be completed at a time, a feed amount is quite large. Engraving and milling machine can be used for optional tool diameter specifications from 1mm-16mm, its tool length of 50 ~ 80mm.

We can use it flexibly, loading fine cutter for fine work and coarse cutter for big work. As the machine design focuses on heavy load, the frame steel is large, Z axis stroke is large, so not only can do small engraving machine process, but also high-speed cutting of thick plates, one time into the amount of up to 20mm-30mm, which is the engraving machine simply can not do the process of manufacturing.
