Precision electric angle table (worm gear): PT-GD304
Product features
1. The stepping motor is equipped as standard, and the motion controller can realize automatic control.
2. The worm gear and worm structure with precise research and matching is adopted, which has comfortable movement, can rotate in any forward and reverse direction, and has small empty return.
3. The rotating shaft system is precision machined by multi-channel technology, with high matching accuracy, large bearing capacity and long service life.
4. The special structural design ensures the low deflection and inclination of the angle table, making the movement more stable.
5. The ingeniously designed air return structure can adjust the air return gap caused by long-term use.
6. The scale circle on the periphery of the table is a laser marking scale, which can rotate relative to the table to facilitate initial positioning and reading.
7. The stepping motor and worm are connected through high-quality elastic coupling, with synchronous transmission and good depolarization performance, which greatly reduces the eccentric disturbance and low noise.
8. The standard mounting hole position can be used alone or matched with other products of our company to form a multi-dimensional motion system.
9. Equipped with limit and zero switches, it is convenient to locate and protect products, and accept product restructuring and customization.
