CNC machining centers, engraving and milling machine, engraving machine the difference between the three

Processing centers, engraving and milling machine, engraving machine, what is the difference between? , many believe that this sentence has just joined the circle of friends will ask, then don't know much about when to buy machinery and equipment, don't know how to distinguish, should buy what kind of equipment, to meet their own needs, CNC's small make up today for everyone a steak grilled the differences between them. Carving and milling machine: just as its name implies is to carve, can also be milling, on the basis of the engraving machine increased the spindle, servo motor, power lathe bed tolerance, but also keep the high-speed 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 the high cost performance, processing speed, good finish machining products, in occupies an important position in the machine tool industry is more and more CNC machining center, Hong Kong and Taiwan, guangdong area called computer gongs, processing parts on a machining center is characterized by: processed parts after once clamping, numerical control system can control the machine tool according to different process automatic selection and replacement of cutting tools; Automatically change the spindle speed, feed and motion trajectory of the tool relative to the workpiece and other auxiliary functions, continuously machining surface is automatically all the artifacts, counter boring, reaming, boring, drilling tapping screw thread processing, milling process. Due to machining center can complete a variety of processes, centrally, automatically to avoid the artificial operation error, reduce the workpiece clamping, measurement time and adjustment of machine tool and workpiece turnover, handling and storage time, greatly improving the machining efficiency and machining precision, so it has good economic benefit. Machining center according to the position of the spindle in the space can be divided into vertical machining center and horizontal machining center. Engraving machine: torque is small, the spindle speed fitted her for small tool processing, focusing on the 'carving' function, is not a great work for the strong cutting pieces. Most 'engraving machine banner currently on the market of products is mainly for processing craft, low cost, because the accuracy is not high, should not be used in the mold development; Engraving and milling machine, machining center. Engraving machine highest spindle speed (compare data r / min) : processing center, 8000; The most common 240000 engraving and milling machine, high-speed machine minimum 30000; Engraving machine is generally the same as the engraving and milling machine, engraving machine used to highlight processing can reach 80000, but that is not a general electric spindle but air bearing spindle. Spindle power: machining center is the largest, from a few kilowatts to dozens of kw; Engraving and milling machine, usually within 10 kw; Engraving machine is minimal. Cutting: machining center is the largest, is especially suitable for heavy cutting, open coarse; Engraving and milling machine, suitable for finishing; Engraving machine is minimal. Speed: because the engraving and milling machine and carving machine is smaller and lighter, their movement speed and feed speed faster than processing center, especially the high-speed machine is equipped with linear motor speed up to 120 m/min precision: the accuracy of the three. Let's first find out three difference between numerical control milling and processing centers for large amount of milling workpiece processing equipment CNC engraving and milling machine used to complete a smaller amount of milling, or soft metal processing equipment of high speed cutting machine is used to complete secondary milling, and the milling with minimal amount of polishing processing equipment after the thorough analysis of the equipment structure and data processing type can help us to make the right choice. Article has been very detailed about engraving and milling machine and machining center, engraving machine, the difference between believe that everyone should be the in the mind to have a certain understanding of these three.
