Will the spindle running speed of Dongguan CNC machining center be affected if it is too fast

Since the development of Dongguan CNC machining center, the total output value has gradually increased, and the domestic machine tool industry has also become increasingly prosperous. The appearance design of most machining centers in the market allows the slicing conveyor to be adjusted to the back of the production line, which is suitable for customized production line arrangements and is also one of the reasons that customers love. This machine adopts a high torque motor, whose output can fully reflect the characteristics of the spindle. The indexing plate has high efficiency and accuracy, including 8 oil circuit joints, one air pressure confirmation is tight, and the activity is high. It can be used with hydraulic fixtures.

The spindle of a large CNC machining center is a vertical machining center, with a fixed column structure. The workbench is rectangular and has no indexing rotation function. It is suitable for machining disk, sleeve, and plate parts, with three linear motion coordinate axes. Moreover, it can be installed on a rotary table rotating along the horizontal axis on the workbench to process spiral parts. The replacement of machine tools adopts pneumatic method, which is convenient and convenient. The machine adopts automatic lubrication method to ensure the excellent operation of all parts of the machine tool.

The machine tool structure adopts the form of a horizontal drag plate, with a reasonable layout. The three-axis feed adopts precision ball screw and servo motor connection transmission to improve transmission accuracy. The X-axis and Y-axis guide rails of the machine are precision rolling linear guides, with high feed sensitivity; The Z-axis uses a rectangular hardened cast iron plastic sliding guide pair, which has excellent vibration absorption; The machine control system adopts an AC servo system, which is suitable for the processing of miscellaneous parts, especially the processing of miscellaneous molds.

The machine tool spindle adopts a servo spindle motor, and the spindle box is equipped with a counterweight device to ensure the smooth operation of the Z-axis. As is well known, the spindle speed of Dongguan CNC machining centers is generally higher, but with the continuous increase of spindle speed, especially reaching fast, various random oscillations, and the added instability of the rotating shaft, exceeding the fatigue strength of the spindle ultimately leads to a reversible increase in spindle rotation error, ultimately affecting the machining accuracy of the machine tool. So the selection of spindle speed is very important.
