Load Bearing 180kg , Diameter 220 Indexing Plate , Motorized Rotation Stage
High precision electric rotary table (worm gear): PT-GD220H
The motorized rotation stage adopts unique shafting structure and wear-resistant precision grinding worm gear, which ensures high rotation accuracy, and the key indexes such as end jump and diameter jump reach the international level. The unique worm gear adjustment mechanism can easily eliminate mechanical errors and ensure long-term accuracy.
Product features
The stepper motor is equipped with 9-pin interface as standard, which can be automatically controlled by the company's motion controller.
The main material is hard aluminum alloy, which has better corrosion resistance. Hard oxidized surface treatment makes the platform less prone to scratches.
The rotating shaft system is made of bearing steel, with high matching accuracy, large bearing capacity and long service life.
The ingeniously designed air return structure can adjust the air return gap caused by long-term use.
The special structural design ensures the end jump and eccentricity of the rotating table, making the rotating motion more stable.
The central through hole of the rotary table has strict coaxiality requirements with the rotary center, and the central aperture of the rotary table has strict matching tolerance restrictions, which is convenient for customers to make precise positioning.
The electric rotary table can be used horizontally or vertically. It can form a multi-dimensional electric adjustment table with other types of tables.
Optional: add limit function, add initial zero position, replace servo motor, install rotary encoder, and accept product restructuring and customization.
The three-phase stepping motor or servo motor can be replaced to increase the speed and torque of the rotary table.
