High precision electric translation table PT-GD140G, precision electric rotating table (worm gear and worm)PX110-100 combination.
High Precision Motorized Linear Stage: PT-GD140G
Product features:
※ Precision ball screw drive, good repeated positioning accuracy and positioning accuracy, small axial clearance and long service life.
※ The guide rail adopts precision linear slider guide rail (square, connected with the bottom plate as a whole), which is comfortable in movement and large in bearing. It is suitable for single axle heavy load or multi axle combination.
※ The fine grinding of the bottom plate of the electric moving table and the reasonable fixing mode of the guide rail greatly reduce the pitch and yaw of the electric moving table, and greatly improve the straightness and parallelism of the movement.
※ Replaceable servo motor and grating ruler for closed-loop control to realize high-speed and heavy load.

Precision Motorized Rotary Stage (Worm Gear): PX110-100
Product features:
※ Stepper motor is equipped as standard, which can be automatically controlled by the company's motion controller.
※ The rotating shaft system is precision machined by multi-channel technology, with high matching accuracy, large bearing capacity and long service life.
※ It adopts the worm gear and worm structure with precise research and matching, with comfortable movement, forward and reverse rotation and small empty return.
※ The ingeniously designed air return structure can adjust the air return gap caused by long-term use.
※ The special structural design ensures the low end jump and eccentricity of the rotating table, making the rotating motion more stable.
※ The central through hole of the rotary table has strict requirements for coaxiality with the rotary center, and the central aperture of the rotary table has strict matching tolerance limits, which is convenient for customers to make precise positioning.
※ 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.
※ Stepper motor and worm are connected through high-quality elastic coupling, with synchronous transmission and good depolarization performance, greatly reducing eccentric disturbance and low noise.
※ The electric rotary table can be used horizontally or vertically, and can form a multi-dimensional electric adjustment table with other types of tables.
※ Limit function can be added, initial zero position can be added, servo motor can be replaced, rotary encoder can be installed, and product restructuring and customization can be accepted.
※ The three-phase stepping motor or servo motor can be replaced to increase the speed and torque of the rotary table.
