What is the difference between CNC engraving and milling machine and engraving machine?

Carving and milling machine and engraving machine in the appearance of the structure are very similar, the following XinTengHui CNC editorial to explain the difference between the two and analysis:

Conceptually: carving and milling machine: as the name suggests.That is, you can carve, can also be milling, engraving machine on the basis of increasing the spindle, servo motor power, bed bearing, while maintaining the high speed of the spindle, and more importantly, high precision.Engraving and milling machine also to high-speed development, generally known as high-speed machine, cutting capacity is stronger, processing precision is very high, but also can be directly processed hardness in HRC60 above the material, a shape.

Engraving machine: it spindle speed is high for small tool processing, torque is relatively small, focusing on the "carving" function, such as wood (specifically for processing wood panels known as wood carving machine), two-colour plate, acrylic panels and other hardness of the plate is not high, is not very suitable for strong cutting of large workpieces.Most of the products on the market under the banner of engraving machine are mainly for the processing of handicrafts, low cost, due to the precision is not high, not suitable for mould development; but there are exceptions such as wafer engraving machine.

From the appearance of: carving and milling machine volume is relatively large, large 1280-type machine volume in 3m * 2m, small 650-type machine is also in 1.8m * 21.9m;; engraving machine volume is relatively small.

From the mechanical structure: engraving and milling machine and engraving machine are generally used gantry structure, gantry structure is divided into building beam type and fixed beam type, the current market engraving and milling machine is to fixed beam type majority.

From the indicators of data: spindle power: milling machine is generally within ten kilowatts; engraving machine is the smallest.Both relative processing minimum are relatively small.

Spindle speed: carving and milling machine common speed within 24,000 rpm, ceramic carving and milling machine can reach 36,000 rpm; engraving machine speed generally can reach 24,000 rpm, and used for high-gloss processing of the engraving machine can reach 80,000 rpm, but the use of the air-floating spindle rather than an electric spindle.

Cutting volume: engraving and milling machine can be small and medium-sized mould roughing, but the efficiency is slower, processing of small and medium-sized more suitable for heavy cutting and roughing, engraving and milling machine is more suitable for finishing; engraving machine cutting volume is smaller, also suitable for finishing, but not for roughing.

Precision: both are suitable for finishing, accuracy is not much difference.

Tool magazine: engraving and milling machine is generally not equipped with a tool magazine, according to customer demand can also choose 6-8 knives inline tool magazine or 12 knives of the bucket type tool magazine can be; engraving machine does not have a tool magazine.

From the application object: carving and milling machine for completing a small amount of milling, but also for small moulds, small and medium-sized moulds, suitable for copper, graphite, ceramics and other processing; while the low-end engraving machine is biased towards wood, acrylic panels, bicolour panels and other hardness of the plate processing, the high-end engraving machine is suitable for metal shells, wafers and so on, the polishing and sanding.

Speaking from the processing size: from the table area on the comparison is a good response to the processing size of how much.Domestic models of the larger table area of 1200 * 800mm (1280 models), the smallest is 500 * 400mm (540 models); engraving machine general processing size will not exceed 450 * 450mm, the common model is 45 * 270mm (250 models)

Through the above detailed answer, I think we need to identify their actual needs when buying machine tools, do not blindly buy, need to compare the models, in-depth analysis of the various structures of the above equipment, helps to help us make the right choice.
