Driven by technological advancements and social development, automation has become a key factor in determining industrial competitiveness. Linear slide modules, essential for precise linear motion, play an increasingly vital role. However, due to the diverse types and models available, improper selection or installation can undermine equipment performance. Thus, mastering scientific selection methods, standardized installation procedures, and systematic maintenance practices is crucial.?
?
I. Scientific Selection Strategies?
?
Selection should be based on a comprehensive assessment of four key factors:?
?
1. Accuracy Matching?
?
High-precision Applications (semiconductor manufacturing, precision machining): Opt for ball screw modules. These Linear Modules, driven by ball screws, can achieve a positioning accuracy of up to ±0.005mm.?
?
General-Precision Scenarios (Material Handling, Sorting): Belt-driven modules are a cost-effective choice. Using synchronous belts for transmission, they typically offer an accuracy of ±0.05mm.?
?
2. Load and Speed Considerations?
?
Belt-driven modules generally support higher loads. For example, a 20mm belt-driven module can carry 30kg, while its screw-driven counterpart can handle around 20kg, making them ideal for heavy-duty handling tasks. Additionally, belt-driven modules have high transmission efficiency, reaching a maximum linear speed of over 2m/s. In contrast, screw-driven modules are limited by rotation speed, usually capped at ≤1m/s.?
?
3. Environmental Adaptation?
?
Cleanrooms (such as in the electronics industry): Select dust-proof modules equipped with sealing strips and made of stainless steel.?
?
Conventional Industrial Environments: Standard modules are suitable but should be protected from direct contact with oil stains and dust.?
?
II. Standardized Installation Procedures?
?
Adhere to the principles of "gentle handling, strict calibration":?
?
1. Pre-installation Preparation?
?
Use a dial indicator to verify that the flatness of the installation surface is within ±0.05mm. This ensures smooth operation and prevents jamming caused by base deformation.?
?
Check the integrity of all components, including linear screws, guide rail sliders, and limit sensors. Discard any rusted or deformed fasteners.?
?
2. Installation Operation Specifications?
?
Lift the module with both hands to avoid distorting the rails. Do not carry it by one hand, and strictly prohibit striking the slider and screw.?
?
Follow a specific fixing sequence: first, pre-tighten the installation screws at both ends, then gradually tighten them from the middle to both sides. Torque values should follow the manufacturer's manual (e.g., 6 - 8N·m for M5 screws) to prevent stress concentration.?
?
After installing the photoelectric limit switches, manually test the module 3 - 5 times to ensure accurate stroke positioning and smooth operation.?
?
III. Full-cycle Maintenance Solutions?
?
1. Lubrication Management?
?
Ball Screw Modules: Apply NLGI 2# lithium-based grease every 500km of operation or monthly through the lubrication holes.?
?
Belt-driven Modules: Check the tension of the synchronous belt quarterly. When pressing the middle of the belt, the deflection should be ≤5mm to avoid slipping due to looseness or excessive wear from over-tightening.?
?
2. Rust Prevention and Protection?
?
In Humid Environments: Regularly wipe the surface of the guide rails and apply rust inhibitors like WD-40. Consider adding rust-proof coatings to metal parts if necessary.?
?
During Long-Term Shutdown: Cover the modules with dust-proof covers to prevent dust accumulation. Before resuming operation, run the modules idle for 10 minutes to remove any potential foreign objects.?
?
As automation becomes more prevalent in CNC machines and industrial robots, linear slide modules have become fundamental to smart manufacturing. Only by integrating informed selection, proper installation, and routine maintenance can their full potential be realized, providing robust support for industrial automation upgrades.
