What is aluminum PU strip wiper: Chip protection wiper for guide rail on CNC machine tools

Aluminum PU strip wiper (also called aluminum wiper, guide rail dust proof wiper) is a protective spare part installing on CNC lathe machines, machine centers, and conventional machine tools to protect the machine guide rail itself. The purpose of installing wiper is to remove the guide rail service, dust and oil film, to prevent the polution remain on the guide rail and cause scratches and abrasions, and will cause machine tool life time and machine positioning accuracy.

Material and specifications: PU scraper strip + aluminum alloy base

Project | Specifications

Scraper Body Material | Polyurethane (PU)

Temperature Range | Approx. -20°C ~ 80°C

Base Material | Aluminum Alloy (Lightweight, Easy to Machin and Cut)

Profile Height | H18 ~ H50, Customizable according to drawings

PU material possesses excellent mechanical strength and chemical stability, and can withstand long-term contact with cutting oil and metal dust without easily becoming brittle or deformed. It is a common material choice for guide rail protective parts.

Why choose this aluminum PU strip wiper blade? Here are 3 major advantages

1. Complete Specifications, Fast Delivery from Stock

We offer various profile heights from H18 to H50, with a long-term stock available. We can quickly ship according to customer drawings, shortening equipment repair/assembly waiting time.

2. Excellent Durability, Long-lasting Protection

Under normal use conditions, it can meet the needs of wear resistance, oil resistance, and metal shavings resistance for approximately 1-2 years, reducing maintenance costs associated with frequent replacements.

3. Lightweight Design, Easy Installation

The lightweight aluminum alloy base is easy to cut and can be adjusted to actual dimensions on-site.

Application scenarios: Which devices require aluminum strip scraper blades?

Aluminum strip scrapers are widely used for slide rail protection in the following equipment:

• Traditional machine tools

• CNC lathes

• CNC machining centers

• Other industrial equipment requiring precision guide rail protection. After installation, they effectively prevent cutting oil, dust, and metal chips from entering the slide rail system, extending the machine's service life and reducing the risk of accuracy abnormalities and downtime caused by guide rail contamination.

Blue PU wiper strip replacement solution: Replace only the consumables, not the base, effectively saving costs.

The lifespan of the aluminum alloy base is generally longer than that of the PU squeegee strip itself. After approximately 1-2 years of use, if only the blue PU squeegee strip is aging and worn, you may not need to replace the entire set; simply replacing the PU strip will restore its original shaving and dust-proofing effects.

Replacement Instructions:

1. Remove the worn and aged blue PU squeegee strip.

2. Clean the grooves of the aluminum alloy base, ensuring there are no residual iron filings or oil stains.

3. Insert the new blue PU squeegee strip into the base slot according to its original specifications.

4. Ensure it is securely fixed and that the squeegee strip fits snugly against the slide rail without gaps.

In-Stock Advantage:

Blue PU squeegee strips are currently in stock and can be purchased individually for fast delivery, providing customers with a cost-effective solution for regular maintenance and consumable replacement.

Frequently Asked Questions (FAQ)

Q1: How long do aluminum scraper blades last?

Under normal operating conditions, they generally last 1-2 years. Actual lifespan varies depending on usage frequency and cutting environment (e.g., oil level, amount of metal filings).

Q2: What is the temperature range of the aluminum scraper blades?

PU scraper blades can withstand temperatures from approximately -20°C to 80°C, suitable for most indoor industrial environments.

Q3: How to choose the appropriate profile height?

It is recommended to choose based on the actual dimensions of the equipment's slide rails and the customer's drawing specifications. Currently, we offer various specifications from H18 to H50, and stock is available for fast delivery.

Q4: Can I replace only the PU scraper blade without replacing the aluminum alloy base?

Yes. If the base is not visibly damaged or deformed, and only the PU scraper blade is worn or aged, it is recommended to replace only the PU blade. Replacing the entire set is unnecessary and can effectively save on consumables and maintenance costs.

Q5: Approximately how long is the lifespan of the blue PU scraper blade?

Under normal use, the blue PU scraper strip can last approximately 1-2 years. Actual lifespan may vary slightly depending on the cutting environment (oil level, amount of metal chips, frequency of use). Regularly checking for wear and replacing as needed is recommended.

Q6: Can the blue PU scraper strip be purchased separately?

Yes. We currently have stock available. The blue PU scraper strip can be purchased separately without needing to be purchased as a set with the aluminum alloy base. This is suitable for customers who already have a base and only need to replace consumables.
