Ensure the installation platform has sufficient rigidity and stability to minimize vibration and resonance during operation; maximize the contact area between the module base and the platform. The flatness of the installation surface is recommended to be no less than 0.05 mm/500 mm, and less than 0.02 mm/500 mm for high-precision applications. Clean foreign objects and burrs on the platform before installation. Use fixing screws of the length and specification specified by the manufacturer to avoid undersized screws (insufficient strength) or oversized screws (interference with sliding components). Follow the locking sequence of tightening from the middle to both ends evenly and sequentially to reduce arching and accuracy degradation caused by deformation.
Classified by transmission type:
Ball screw type: High positioning accuracy, large thrust
Timing belt type: High speed, long stroke, low cost
During motor installation:
For direct-coupled models, accurately align the motor flange holes with the screw shaft ends.
For side-mounted models, ensure the two timing pulleys are flush with an alignment error not exceeding 0.5 mm.
Install 3 sensors in the side groove of the module (recommended configuration: 1 for the starting/origin point + 1 each for positive/negative limit positions). Configure a cable carrier if necessary and avoid winding or interference with sensor and motor cables.
After mechanical installation, perform a power-on test run to check for abnormalities such as abnormal noise, jamming, or shaking. Conduct accuracy testing or put the system into process use only after confirming normal operation.
An electric sliding table is typically composed of the table body + motor + driver + controller/operation panel. After power-on, parameter setting and motion control are performed via the operation panel or host computer.
Select the motion mode and coordinate system, set parameters such as target position, speed, and acceleration/deceleration. Execute the Homing function to establish a reference position and ensure consistency of subsequent positioning.
Achieve multi-point motion using absolute/relative positioning. For multi-axis combinations, plan interpolation trajectories according to process requirements to avoid impact caused by sudden start/stop.
Set reasonable soft/hard limits and sensor interlocks to prevent overtravel and collision. Configure emergency stop and alarm circuits if necessary.
Before initial use, wipe off anti-rust oil and apply lubricating oil/grease as required by the manufacturer; do not mix lubricants of different types. After lubrication, move the sliding carriage back and forth for at least 3 slider strokes, repeating the operation ≥ 2 times to ensure a uniform oil film forms on the guide rail surface.
It is recommended to use the equipment at room temperature and avoid contact with corrosive media. If hands are sweaty before operation, reapply anti-rust oil after touching the guide rails. For long-term shutdown or storage, coat the surface with anti-rust oil, seal it for preservation, and place it horizontally as much as possible, avoiding extreme temperature and high-humidity environments.
Perform the first maintenance on new equipment after approximately 2 months of operation. Subsequent maintenance is recommended monthly (adjustable based on working conditions), and check whether the lead screw grease needs replenishment.
Only authorized personnel are allowed to operate the equipment. Before operation, confirm that the power is turned off and no tools or personnel are within the motion path. Maintain a safe distance during operation; it is strictly prohibited to insert hands, feet, or tools into the motion area. If equipment abnormalities occur (abnormal noise, odor, overheating), stop the machine immediately and report the issue. In case of emergencies, cut off the power supply before handling.
When abnormal noise occurs, distinguish the type:
Noise that intensifies with increased voltage/load is mostly electromagnetic noise.
Noise related to rotational speed but less related to voltage/current is mostly mechanical vibration or ventilation noise.
Check the power supply voltage, load, motor windings, and bearing conditions. Tighten loose components and inspect the alignment of couplings/timing pulleys and belt tension. If necessary, reduce the speed, optimize the acceleration/deceleration curve, and re-test.
Clarify the following parameters according to process requirements: accuracy (positioning/repeat positioning), speed, load (including offset load/torque), stroke, environment (cleanliness, dust, temperature and humidity), and installation method (top/bottom mounting, horizontal/vertical installation).
Ball screw type is preferred for high-precision applications, applications requiring large thrust, and Z-axis applications.
Timing belt type is preferred for long-stroke, high-speed, and cost-sensitive scenarios.
Speed is jointly affected by motor speed and lead screw pitch. A larger pitch results in higher linear speed at the same motor speed (it is necessary to verify the load and acceleration/deceleration capacity simultaneously).
Multi-axis combinations can form Cartesian coordinate mechanisms such as XY cross, XYZ cantilever, and gantry structures. Pay attention to load distribution, rigidity matching, and synchronization error control of each axis.
