Here's how to "use" telescopic way covers effectively:
1. Proper Installation (Crucial for Functionality):
Mounting in Compressed State: Telescopic covers are almost always mounted onto the machine in their fully compressed (closed) state. This ensures correct alignment and prevents tension when the machine moves.
Smallest Box First, Then Largest: Typically, the smallest box (the one that extends furthest from the fixed end) is anchored first to the machine bed or fixed part, ensuring it's level and perpendicular to the direction of travel. Then, the largest box (the one attached to the moving part) is secured.
Alignment is Key: Ensure that all mounting surfaces are perfectly aligned and not slanted. Any misalignment can cause binding, excessive wear, or damage to the cover sections and wipers.
Smooth Gliding Surfaces: The cover's side guides and rollers (if present) must slide smoothly along the machine's guideways or the cover's own guide tracks. Check for any "steps" or obstructions that could impede movement.
Secure Fastening: All mounting screws should be properly tightened and often secured with a locking compound (e.g., Loctite) to prevent loosening due to vibration.
Initial Slow Operation: After installation, it's critical to run the machine at a very slow speed through its full range of motion. This allows the cover to "break in," ensures all boxes open and close freely without jerking or binding, and confirms that there are no collisions with other machine components. Lubrication is often applied during this initial slow movement.
Lifting Lugs: For large and heavy covers, use designated lifting lugs or points during installation to prevent damage to the cover panels.
2. Regular Maintenance (Extending Lifespan and Effectiveness):
Daily Visual Inspection:
Look for dents, damage, or signs of impact on the external surfaces.
Check wipers for wear, streaks on the cover, or chips collecting beneath the sealing lip. Worn wipers are a primary cause of contaminant ingress.
Daily Cleaning:
Remove chips and debris from the cover surfaces and between sections using a coolant spray wash at the end of each shift.
Crucially, do not use an air hose to blow off chips. This can force fine chips and coolant under the wipers and into the machine's precision components, defeating the purpose of the cover.
If a spray wash isn't available, carefully wipe or brush off chips.
Lubrication:
If the cover surfaces appear dry or after extended idle periods, wash them down with coolant and then apply a light lubricating oil (as recommended by the manufacturer) to the external sliding surfaces.
Cycle the cover slowly through its full travel after lubrication to ensure even distribution.
Listen for Unusual Noises: Squeaking, scraping, or loud impact noises can indicate issues with internal gliders, rollers, or damping elements. These should be inspected by a qualified technician.
Check for Irregular Movement: If the cover jerks, vibrates, or skews, it might indicate misalignment, defective guide elements, or worn out components.
Wiper Replacement: Wipers are wear items. Replace them when they show signs of porosity, excessive wear, or are no longer effectively sealing out contaminants. Many modern designs allow for relatively easy wiper replacement in-house.
Damage Repair: Any dents or significant damage should be addressed promptly by a professional. Deformed panels can hinder proper movement and compromise protection.
Adhere to Manufacturer's Guidelines: Always consult the specific manufacturer's assembly and maintenance manual for detailed instructions, recommended lubricants, and service schedules, as these can vary by design and material.
