five points selection to buy CNC engraver

First, select the size format

Customers should be based on business needs and financial situation, their own selection of suitable models cnc engraver size and power. Small size cnc engraver has the 600mm × 600mm and 600mm × 900mm, the width of the feed are 700mm. Two-color plate engraving cnc engraver are the most basic small size of the application, the admissibility of good. Then a smaller price cnc engraver and its almost the same color but the carving board to the Conference Board, more trouble and an unnecessary waste. Large format cnc engraver has a 1200mm × 1200mm, 200mm × 1500mm, 1500mm × 2400mm, 2400mm × 3000mm, the above models into cnc engraver Branch more than the width of 1350mm, is now available in the market plexiglass and PVC board size is 1300mm × 2400mm, so that several models of the demand for large format cnc engraver suitable comparison of the client.

Two, the spindle motor Spindle motor cnc engraver computer are the essential components, the performance of the computer machine cnc engraver has a critical impact on performance.

Axis processing is usually divided into two categories: high-power precision machining and cutting spindle axis. 1, fine processing of the spindle is characterized by low noise, high speed, height, suitable for fine processing of the workpiece in particular, such as seals, nameplates, badges and other gifts. Such high-speed variable frequency electric motor usually, the smaller the power, as the following at 250W.

Thick are cut off the disadvantage of the weaker material, not cut off the thicker material. 2, high power to cut off the main axis, mainly used for cutting, high-power moment, and there is a big power, cutting ability, especially suitable cut-yu, three three-dimensional character of course, you can create badges, nameplates, seals and so on. Such high-power spindle motor in accordance with the general characteristics of the frequency can be divided into high-speed brushless AC motor and AC motor brushes, the main difference is: A, high-speed brushless motor inverter, variable speed range from 70060000 to / min, and in general there is AC motor brush not exceeding the maximum speed of 24,000 rev / min: B, brushless motor rotating frequency and high precision, wear a small, low noise, the noise is much lower than for AC motor has brushes; C, brushless frequency conversion motor stall characteristics of good, because of Inverters have special restrictions on circuit, a short period of time will not stall the motor burned, and there is brush machine communicate at overload or stall smoke when burned very quickly and does not repairable; D, brushless frequency conversion motor the use of variable frequency speed control technology is the major product class, long life, the manufacturers were shifting to provide one year free, after high-speed through the replacement of bearings on the motor maintenance, and because of the use of brush AC motor electric Jazeman Life expectancy at around 300 hours on the replacement motor or a brushless motor, brushless AC motor therefore does not guarantee the day usually. Control mode and speed selection: control can now be divided into three types: A, all computer-controlled operation has completed the work, cnc engraver at work in a computer job status, the layout can not be carried out other job, so that the computer probably solid waste caused by misoperation. B, single-chip computer control, the controller cnc engraver at work in publishing at the same time, but you can not turn off the computer, which in fact is equivalent to a savings of 7 computer and the computer reduces the waste caused by misoperation . C, using USB port to transfer data, the system has a memory capacity of more than 32M. Save files as long as you can now completely divorced from the computer, turn off the computer or other typesetting. This approach greatly improved the efficiency of the cnc engraver.

IV Guides Large format cnc engraver must be used imports widened the square rail, the load capacity and accuracy to maintain the capacity of rail are round for more than 30 times to ensure the high quality high-speed cnc engraver. Friday, precision 1mm smaller format machine carved Chinese characters, or large format cnc engraver engraved 1.5mm small print, under the magnifying glass at should be very clear to see.
