motor driven rotary table in stock

PI’s direct-drive rotary tables with frictionless, brushless, closed-loop torque motors provide the best combination of high accuracy, high velocity, and maximum service life. PI provides closed-loop direct drive rotary tables with both mechanical bearings and air bearings. Stage models with large apertures and low profile are available. The stage design is optimized for high speed, stiffness, and high load capacity. If completely friction-free and maintenance free motion with virtually unlimited lifetime is required, air bearing rotation tables are recommended. These ultra-precision, high-speed rotary tables provide vibration-free motion with extremely high accuracy and negligible runout, wobble and eccentricity errors. The lack of lubricants makes these also clean room compatible and ideal for any high-performance metrology application in optics, photonics, and semiconductor manufacturing, test and metrology related projects.

In contrast to worm gear driven rotary stages or belt-drive rotation stages, torque-motor direct drive stages eliminate play in gears, couplings or flex in drive belts, providing motion with zero backlash and excellent constancy of velocity, while achieving higher speed than worm-gear drives.

PI’s precision direct-drive, positioning tables can be used in high performance factory automation, research, semiconductor, and laser processing applications. Due to the use of brushless high-torque, motors with direct metrology position feedback, backlash is completely eliminated, and reliability is greatly improved.

With modern direct-metrology rotary encoders, sensor resolution down to 1/100th of a microrad is available on select models with large rotary table platforms, using the high interpolation factors

Based on the high encoder resolution and powerful servo controllers, the direct-drive rotary tables also provide excellent velocity control, which is required in automation applications including high-speed laser processing, indexing, and semiconductor wafer inspection.

Most Direct Drive Rotation stages can be mounted horizontally and vertically, and with combinations all 3 rotary degrees of freedom (3DOF, pitch, yaw, and roll) can be addressed.

Sherline offers one of the finest small rotary tables on the market. It is available in manual or stepper motor drive modes. It can even be purchased with its one controller to be used as a programmable indexer.

can mount our chucks. This modification came about after requests from our laser engraving customers. The larger through hole allows for larger stock to be held. It also has a Nickel-Teflon plating on it because it was designed to be used in an every-day production environment. This gives the table a rust resistant surface that is hard and has added lubrication qualities.

Sherline�s rotary table offers an accurate, stable platform for rotary laser marking applications. Its compact size makes it a good fit in small enclosures. Visit our Video page to watch a Sherline CNC-ready rotary table in use in a laser marking application on round parts, illustrating the difference between trying to mark on a round part without rotating it vs. rotating it. Some of the videos are from Jimani Inc. Laser Marking Systems who use a high-speed motor to drive the table.

The maximum capacity of the turntable is not easily specified as it very much depends on how the turntable is used. If you apply a load axially the capacity is very high - in fact it is possible to stand on the rotary table and have it spin you in a circle. If however you have a large over-hanging load that creates a lever arm the capacity is significantly less. The maximum recommended load for the pan/tilt bracket is about 5kg. This can be significantly increased if the load is attached to the side of the turntable instead of over the top.

HIWIN Corporation Torque Motor Rotary Tables (TMRT) use a direct-drive torque motor, built-in high-rigidity and high-precision bearings, absolute encoders and powerful brake system to ensure excellent acceleration capabilities and high precision uniform movements. HIWIN TMRTs are backlash-free, optimized for high torques, have robust dynamics and are highly adaptive to the most demanding of automation processes. Compared with the mechanical indexing table, TMRT has high speed and high torque characteristics, suitable for the needs of various machining equipment.

This is a modification of our 4″ CNC Rotary Table with Stepper Motor. This modification came about after requests from our laser engraving customers. They wanted a rotary table that had a larger through hole to which you could mount our chucks.

This version of the Sherline rotary table has a Nickel-Teflon plating on it because it was designed to be used in an every-day production environment. This gives the table a rust resistant surface that is hard and has added lubrication qualities.

The table is 2″ high and 4″ (100mm) in diameter. The main components have been machined from solid bar stock steel, and the complete unit weighs seven pounds. The table has been engraved with a laser, giving sharp and precise lines every 5°, numbered every 15°. These lines are calibrated with the 72-tooth worm gear that is driven by the handwheel or stepper motor. The handwheel is divided into 50 parts, making each line on the handwheel 1/10°. This allows a circle to be divided into 3600 increments without interpolation. Seventy-two revolutions of the handwheel rotate the table one revolution.

There is no mechanical reduction mechanism such as a worm system in a rotary table with a DD motor. DD (Direct Drive) motor is built in the rotary table to drive directly. The compact two-axis direct drive rotary table enables rapid acceleration/deceleration and high-speed rotation. Its biggest advantage is the super high speed up to 2000 rpm. Thus, it can work as a mill/turn component. As a result of the lack of a mechanical reduction mechanism, the driving torque of the rotary table is not strong. It is necessary to choose an application for the rotary table with a DD motor.

A high torque motor drives the direct drive rotary table directly. There is no backlash or abrasion generated during rotation because it is not driven by worms and gears. Typically, these rotary tables are used in applications requiring high accelerations and decelerations, such as blade machining. For high-speed drilling centers with very important indexing times, a two-axis direct drive rotary table is an excellent choice.

The 200RT Series Rotary Tables are designed for precise motor-driven rotary positioning and indexing. These tables are designed to function independently or in conjunction with linear tables used for precision automation applications. Their low profile design minimizes stack height in multi-axis configurations and enables them to fit in many places where other motorized rotary devices cannot. Models are available in 5, 6, 8, 10, or 12 inch diameters and are offered with four gear ratios making it convenient to match size, speed, and load requirements. They can be selected in either English or metric mounting. They are found in virtually all industries where intermittent part indexing, part scanning, skew adjustment, or precise angular alignment is required. At the heart of these tables is a rugged main support bearing which is comprised of two preloaded angular contact bearing races. It is designed for high load capacity and smooth, flat rotary motion. The drive is a precision worm gear assembly which is preloaded to remove backlash. The top and base are constructed of high quality aluminum with an attractive black anodized finish. The top and bottom mounting surfaces are precision ground to assure flatness.

IEF rotating units of the DT series comprise of stainless steel and aluminium. They are available in many different designs. The rotary tables DT 80/100 or DT 100/140 are designed for motor-powered operation. They work with a high-quality screw gear, with a reverse play which can be minimised by supply of the screw wheel. The hollow shaft gives the constructor additional space for putting hoses and cables.

Corresponding motor flanges incl. pluggable coupling systems are available for attachement of step or servo drives. A pluggable reference point switch is used for motors with a resolver system.
