The choose and buy small engraving machine need what to problem note?

Small engraving machine of choose and buy should consider the following questions: 1. Machine structure is reasonable according to the structure points: pillar and gantry planer are divided into fixed and mobile of longmen longmen. Column and fixation of the gantry good rigidity. According to material: aluminum alloy, steel, cast iron, weight increase, in turn, in turn, increase the rigidity, as long as not milling steel, wood carving jade copper aluminum these material, soft metal or lightweight milling copper aluminum, aluminum alloy frame can meet the requirements. 2. Electric performance is stable electrical performance mainly depends on how electric control part of the anti-interference ability, general electric control points mach3 control and the macro control, relatively d macro performance is stable, but the Mach USB version of control card one thousand or so that is also very stable, often see most of the carving deformation is to use the parallel mach3 control, this kind of parallel mach3 performance is the most unstable, may have no matter to 3 in computer. Effective stroke whether meet the requirements of you depends on your need to sculpture of the dimensions of the big size, but not blindly pursuing big trip, just enough. 4. Spindle motor products performance is good, if you do, so must use water cooling spindle, work more best 4 water-cooled spindle bearing, otherwise life is relatively low. 5. Carving carving speed determines the work efficiency, the carving effect under the premise of meet the requirements, of course, the faster the better, the speed is not a simple and F value directly, but also look at motor acceleration, the greater the acceleration value can be set, the actual engraving speed is more close to the F value, ran straight line at the end of the beginning and affected by acceleration is big, the middle for the F value, the better the F value, the lower the relative quality of carving, acceleration value, the higher the transition section, the more precise the premise machine strength is enough, enough and stepper motor drives.
