1, spindle speed. Generally, the maximum spindle speed of machining center is below 8000rpm.
2. The size of the longitudinal stroke, the structural layout of aluminum profile machining center has three types: gantry type, movable column type and movable beam type, which are reflected in the performance indexes of machine tool such as rigidity, smooth operation and convenient operation. The selection should be based on your personal data requirements.
3, precision rigidity, this point is not to look at the height, but to choose moderate, high positioning accuracy and rigidity is of course good, but the cost is relatively high.
I suggest you make a comparison among the better brands of profile machines such as Pradie, Draghi and Parker.
