Being a work host ,machine tools bear half of the workload of machinery and equipment manufacture. Therefore, high accuracy, high repeatability and high efficiency have been the important norm to measure the performance of machine tools. Motor drive system as the executing agency of machine tools, will determine the merits of these performance indicators. Megmeet SVM servo drive system, MV600, MV300 and MT160 drive can provide a comprehensive solution for all types of machine tools, and have a mass of mature applications.
Machine tools spindle
Common lathe spindle
Asynchronous open-loop spindle
MT160 is a new type of machine tool spindle dedicated drive, using no speed sensor vector control algorithm.It has international leader performance in motor control, and customize factory parameters for machine tool spindle applications. In the case of matching motorsthere is no need to set parameters. Applications of machine tool using MT160 have the following characteristics:
The maximum carrier frequency of MT160 series drive can up to 16k, running frequency up to 1500Hz in V / F mode, operating frequency can up to 650Hz in open loop vector mode,
Low frequency torque is big, a corresponding increase in mechanical feed rate and cutting depth , improving the efficiency
Wide speed range, weakening control can up to 6:1 in open-loop vector control.steady speed under weakeningmagnetic, good surface treat
Fast torque response, accelerate and decelerate rapidly, improve efficiency
"BACK OFF" function ensure that the drive is still able to run to the highest speed when it encountered large load, to eliminate "chipping"
Asynchronous closed-loop spindle
Synchronous closed-loop spindle
As a synchronous and asynchronous integration drive,SVM series servo driveis widely used in high-precision engraving and milling machining center, CNC precision automatic lathe, complex CNC machining center, its characteristics are:
High zero speed lock axis-force, high positioning accuracy
Positioning rapidly, changing tool faster
Maximum closed-loop 1200HZ , low speed torque large
When load change rapidly, fasttorque response , good speed stability
Strong anti-interference ability
