Product Detail

Product Tags


● Standardly equipped with stepper motor and RS232 interface, the company's independently developed WNSC series motion controller can realize automated control
● The rotating shaft system is precision processed using multiple processes, with high matching accuracy, large load-bearing capacity and long service life.
● Using a precision-matched worm gear structure, the movement is comfortable and can rotate in any forward and reverse directions with minimal backlash.
● Exquisitely designed backlash elimination structure, which can adjust the backlash gap caused by long-term use
● The special structural design ensures extremely low deflection and tilt of the corner table, making the movement more stable.
● The scale ring on the periphery of the table is a laser-engraved ruler. The ruler can rotate relative to the table to facilitate initial positioning and reading.
● The stepper motor and worm are connected through imported high-quality elastic couplings, with synchronized transmission and good depolarization performance, which greatly reduces eccentric disturbance and has low noise.
● The electric corner table can be used horizontally or vertically, and can be combined with other types of tables to form a multi-dimensional electric adjustment table.
● The electric angle tables are designed in pairs and can be stacked or used alone. The two rotation radii are carefully designed. After superposition, they can rotate orthogonally in two dimensions around a total point.
● Has limit function, initial zero function, replaces servo motor, installs rotary encoder, accepts product modification and customization
