Do you know the difference between engraving and milling machine, engraving machine and machining center?
Do you know the difference between engraving and milling machine, engraving machine and machining center?I believe that many friends do not understand when they buy mechanical equipment, do not know how to distinguish, in the end should buy what kind of equipment, in order to meet their needs, today I will tell you about the difference between the three:
1, CNC milling and machining center for the completion of a large amount of milling workpiece processing equipment.
2, CNC engraving and milling machine for the completion of small milling volume, or soft metal processing equipment.
3, high speed cutting machine tool is used to complete the medium milling amount, and the milling amount of grinding to the lowest processing equipment.
An in-depth analysis of the above equipment structure and data processing types can help us make the right choice.
1. Engraving and milling machine:
As the name suggests, it can be carved and milling. On the basis of engraving machine, it increases the power of spindle and servo motor, and the bearing capacity of the bed, while also maintaining the high speed of the spindle.Engraving and milling machine to high speed development, generally known as the high speed machine, cutting ability is stronger, the machining accuracy is very high, also can be directly processed material hardness above HRC60, a forming, is widely used in precision mold cavities a complete rough finish machining, mold copper electrode and aluminum products processing, shoes mold manufacturing, fixture processing, eye clock industry.Due to high cost performance, fast processing speed and good finish of processed products, it occupies an increasingly important position in machine tool processing industry.CNC machining center: Hong Kong and Taiwan area, Guangdong area is also known as the computer gong, in the processing center processing parts are characterized by: processed parts after a clamping, CNC system can control the machine tool according to different processes automatically select and replace the tool;Automatically change the machine spindle speed, feed and tool relative to the workpiece movement track and other auxiliary functions, continuously on the workpiece processing surface automatically for drilling, shaving, reaming, boring, tapping, milling and other processes.Because the machining center can be centralized, automatic to complete a variety of procedures, to avoid the artificial operation error, reduce the workpiece clamping, measurement and machine adjustment time and workpiece turnover, handling and storage time, greatly improve the processing efficiency and processing accuracy, so it has good economic benefits.Machining center according to the location of the spindle in space can be divided into vertical machining center and horizontal machining center.
2. Engraving machine:
The torque is relatively small, high spindle speed is suitable for small tool processing, focusing on the "engraving" function, not suitable for strong cutting of large parts.At present, most of the products in the name of engraving machine on the market are mainly for processing handicrafts, low cost, because the accuracy is not high, should not be used for mold development;Engraving and milling machine, machining center.Engraving machine index data comparison spindle maximum speed (r/min) : machining center 8000;Engraving and milling machine is the most common 240000, the lowest 30000 high-speed machine;Engraving machine is generally the same as engraving and milling machine. The engraving machine can reach 80000 for high gloss processing, but it is not used for the general motorized spindle but the air floating spindle.Spindle power: machining center is the largest, from a few kilowatts to tens of kilowatts;Engraving and milling machine next, generally within ten kilowatts;Engraving machine is the smallest.Cutting amount: machining center is the largest, especially suitable for heavy cutting, open rough;Engraving and milling machine next, suitable for finishing;Engraving machine is the smallest.Speed: because engraving and milling machine and engraving machine are relatively light, their movement speed and feed speed is faster than the processing center, especially equipped with linear motor high-speed machine movement speed up to 120m/min.Accuracy: The accuracy of all three is similar.From the processing size: the table area can be a better response to this.China mainland processing center (computer gong) minimum table area (unit mm, the same below) in 830*500 (850 machines);Engraving and milling machine of the largest table area in 700*620 (750 machines), the smallest is 450*450 (400 machines);Engraving machine generally does not exceed 450*450, the common is 45*270 (250 machines).
3. In terms of application objects:
Machining center for the completion of a large amount of milling workpiece processing equipment, large mold, hardness is relatively hard material, but also suitable for ordinary mold open rough;Engraving and milling machine is used to complete small milling volume, small mold finishing, suitable for copper, graphite and other processing;Low-end engraving machine is biased to wood, two-color plate, acrylic plate and other plates with low hardness processing, high-end suitable for wafer, metal shell polishing and grinding.In foreign countries, there is no word of CNC engraving and milling machine. Strictly speaking, engraving is a part of milling, so foreign countries only have the concept of processing center, and from this, the concept of small processing center is derived to replace the engraving and milling machine.Buying engraving machine or buying CNC milling machining center is often to ask their own questions, depending on the actual production needs.In addition, there are currently prevailing high speed cutting machine tools (HSCMachine), the Chinese mainland is called high speed machine.I have been very detailed about the difference between engraving and milling machine and processing center and engraving machine, I believe you should have a certain understanding of the three in your heart.
