Products Features
Accuracy of location at the micron level
The device uses an imported servo motor and a precision harmonic reducer to achieve positioning accuracy of ±5 arc seconds (repeatability ≤30 arc seconds). This makes sure that the dimensions stay the same throughout multi-station machining (for example, automobile bearing bore machining error ≤0.01mm).
Design for high-rigidity load-bearing
The unit is made of a single piece of QT450 ductile iron and has crossed roller bearings. It can handle an axial load of up to 5000N and a tipping moment of at least 2000N·m. It can directly carry workpieces that weigh up to 50 kg for heavy-duty machining like drilling and milling.
Fully sealed protective structure
Fluororubber seals are utilized at the unit's joints and have an IP65 protection rating. This makes sure that the unit operates well in dusty and coolant-splashed workshop conditions and cuts down on maintenance.
How to use It to achieve high-precision positioning?
1. Make rather exact use of sensors
Encoders or high-precision angle sensors let the hollow rotating table track its speed of rotation and position. These sensors provide quite exact feedback signals, which will help the control system to accomplish really great-precision placement.
2. Fix the mechanism of control
First utilising an ideal approach, the control system should find the turntable's location and speed; subsequently, it should modify it in response to feedback signals. One can use the PID control method, for example, to vary the spinning platform's acceleration and deceleration, thereby getting more ideal placement.
3. Approval and calibration
The great-precision placement is found by the hollow spinning table during calibration and adjustment. This consists in changing factors including the angular deviation, friction, and turntable inertia to guarantee correct turntable alignment to the objective position.
4. Activate rather accurate motors and drives
Great-precision placement depends on the servo driven rotary indexing table running motors and drives with high accuracy. Enough torque and speed on these devices should provide considerable accuracy in the movement of the spinning table.

How to install the product
How to install It
Initially, it is advisable to reserve a motor outlet and mounting hole on the mechanical equipment mounting plate to expose the motor part of the rotary indexing table. Then as shown below place the rotary indexing table on the mechanical equipment mounting plate using the two positioning pin holes. Then securely fixes the rotary indexing table on the mounting plate with personnel. (As illustrated below)
How to install a load on It
Install the load using the 6 mounting screw holes on the rotary indexing table's turntable.The location of the load can be ascertained by means of two pin holes designed for load installation on the rotary indexing table. The load has to have the positioning pins securely set on it.
Can be equipped with 2KW servo motor
Mostly utilised for high-precision and high response speed control uses, a 2KW servo motor is a servo motor with a rated power of 2 kilowatts. Usually featuring feedback systems (such as encoders), servo motors enable exact position, speed, and torque control. Common applications for this kind of motor are CNC machine tools, robotics, automation equipment, and other systems needing exact motion control. 2KW servo motors are extensively applied in industrial and manufacturing sectors because of their great efficiency and adaptability.
Applications needing great accuracy and fast response speed usually call for a 2kW servo motor combined with a hollow rotating platform. Features and benefits of this arrangement consist in:
1. Perfect position and speed control offered by servo motors fit for demanding uses.
2. Suitable in industrial settings, a 2kW servo motor can drive substantial weights.
3. Especially in space limited locations, the hollow design lets pipes or cables flow at the centre of the platform.
4. Low speeds and high loads allow servo motors to keep great efficiency, hence lowering energy usage.
5. Widely utilised in robots, automated manufacturing lines, CNC machines, and other equipment needing sophisticated motion control is this combination.
6. It can be connected with additional sensors and control systems to improve automation degree and precision even more.
Typical application scenarios
Processing of automotive parts: drilling engine blocks from different angles and chamfering brake discs. With precision indexing, you may do many processing stages in one clamping operation, which makes the process 40% more efficient.
Putting together 3C products: Attaching mobile phone midframes with screws and laminating camera modules. Allows for small adjustments of 0.1°, which keeps assembly tolerances to ≤0.02mm.
Making medical devices: using a laser to mark the scales on syringe plungers. High-speed indexing guarantees a positioning inaccuracy of ≤5 arc seconds, which keeps the scale clear.
Fresh Energy Battery Testing: Inspecting battery electrode plates at several stations for thickness, flatness, and flaws with continuous indexing speeds of up to 20rpm meets the needs of mass production testing.
FAQ
Q: What are the core differences between servo-driven rotary indexing tables and hollow rotary platforms?
A: While both are rotary positioning devices, their application scenarios differ:
Servo-driven rotary indexing tables specialize in intermittent indexing (e.g., 90°/180° step-stops) and offer higher positioning accuracy (±5 arc-seconds), making them suitable for multi-station processing, assembly, and other applications requiring precise stops.
Hollow rotary platforms excel at continuous rotation, with a central hollow structure suitable for pipework, making them more suitable for inspection and handling applications requiring 360° continuous operation. They typically have higher rotation speeds (above 50 rpm).
Q: What details should be considered during installation? Does it require professional operation?
A: Three key points to note during installation:
Base fixing: Use high-strength bolts (e.g., grade 8.8 or higher) to secure the base to a flat work surface to prevent positioning errors caused by looseness.
Concentricity calibration: When docking with upstream and downstream equipment (such as robotic arms and conveyors), concentricity deviation must be controlled within 0.1mm. This can be calibrated using a dial indicator.
Cable routing: Route servo motor cables away from high-voltage lines to avoid electromagnetic interference.
Q: What routine maintenance is required? How often do wearing parts need to be replaced?
A: Daily maintenance includes:
Weekly: Clean dust and oil from the work surface and guide rails, and check for loose bolts.
Monthly: Apply special grease to the rotating axis bearings to prevent dry friction.
Quarterly: Use the control system to check positioning accuracy deviation. If it exceeds ±10 arc seconds, recalibrate. The replacement cycle for wearing parts (such as seals and bearings) depends on the frequency of use. Under conditions of continuous operation of 8 hours per day, it is generally replaced every 2-3 years. If used in dusty and humid environments, it is recommended to shorten the replacement cycle to 1-1.5 years.
