What is a scraper blade?

Scraper blades (also known as track scrapers or oil scrapers) are protective components installed on the end faces of the tracks in metal cutting equipment. During operation, the scraper blades adhere closely to the track surface, blocking and scraping away metal chips, cutting oil, and dust, preventing impurities from entering the track surface. This maintains machining accuracy and extends the equipment's lifespan. The track type and dimensions of the scraper blades can be customized, including for dovetail slides.

Why do machine tool tracks need scraper blades?

During metal cutting, if chips and cutting oil continuously adhere to the slide rail surface and are carried into the rail as the mechanism moves, common consequences include:

• Scratching and accelerated wear of the rail surface, leading to a gradual decrease in machine positioning accuracy.

• Chips mixed with the lubricating oil film create an abrasive effect, shortening the lifespan of the slide rail and dovetail seat.

• Repairs after accuracy loss often require scraping or replacing the rail, which is far more costly than preventative measures.

Installing scraper blades on the rail end face is a low-cost, easy-to-replace, and direct protective measure—it simultaneously scrapes away surface impurities each time the mechanism moves, preventing foreign objects from entering the rail at the source and improving machine safety.

Product structure and materials

Project | Description

Product Structure | Divided into two parts: "Sheet Metal" and "Scraper Tongue"

Sheet Metal | Standard carbon steel sheet metal construction, providing stable support for the scraper tongue

Scraper Tongue | Selected according to requirements, using oil-resistant and wear-resistant rubber to scrape impurities against the track surface

Track Type | Suitable for flat tracks, dovetail slides, etc.

Dimensions | Customized design and manufacturing based on actual track type and dimensions

Three major advantages of scraper blades

1. Fully Customized: Designed and manufactured to fit the track dimensions and shape, eliminating the need to conform to standard products. The fit directly impacts the protective effect.

2. Oil- and Wear-resistant Rubber Scraper Tongue: The scraper tongue is in constant contact with cutting oil and metal shavings. Made of oil- and wear-resistant rubber, it boasts a longer lifespan and sustained scraping performance.

3. Applicable to Dovetail Slides: In addition to standard flat tracks, traditional dovetail slides commonly found in machine tools can also be customized with corresponding scraper blades.

Application Scope

• Traditional machine tools: Protection of slideways and dovetail mounts on lathes, milling machines, etc.

• CNC lathes: Prevents chips and cutting oil from entering the slideways, maintaining long-term machining accuracy.

• Machining centers: Protection of slideway end faces, reducing accuracy loss and maintenance frequency.

• Track and slideway protection for other metal cutting equipment can be customized according to the track type.

Customization process

1. Provide requirements: Machine model or track type (flat track/dovetail mount), track dimension drawing or on-site measurement data, quantity

2. Specification confirmation: We will design the corresponding sheet metal form and scraper specifications.

3. Quotation and delivery date confirmation

4. Production and shipment

Frequently Asked Questions (FAQ)

Q1: What is the main function of the scraper blade? The scraper blade is installed on the end face of the machine tool track. During operation, it scrapes away and prevents metal chips, cutting oil, and dust from entering the slide rail or dovetail mount, maintaining machining accuracy and extending the machine tool's lifespan.

Q2: What is the structure and material of the scraper blade? The scraper blade consists of two parts: a sheet metal frame and a scraper tongue. The sheet metal frame is made of ordinary carbon steel and is responsible for support and fixation. The scraper tongue is made of oil-resistant and wear-resistant rubber, which adheres closely to the track surface to perform the scraping function.

Q3: Can scraper blades be installed on dovetail mount slides? Yes. In addition to general flat tracks, this product is also suitable for dovetail mount slides. Custom designs and manufacturing can be made according to the dovetail mount's form and angle.

Q4: Can non-standard sized tracks be customized? Yes. The track form and size of the scraper blade are custom-designed and manufactured. Provide the machine tool model, track drawing, or measured dimensions for evaluation.

Q5: Does the scraper need to be replaced after the scraper tongue wears down? The scraper tongue is a consumable part and will naturally wear down over time. The actual replacement method and cycle depend on the usage environment. Please contact us for an assessment.

Q6: How can I get a quote? Provide the track type, dimensions (drawings or measurements), and quantity for a quote.
