BIAX Precision Scraper Overview
Designed for vertical surfaces, reducing physical effort and saving time. Operates with a pulley system for efficient crosswise scraping.
Blade Radius and Tilt Angles
Results vary based on blade radius and tilt angles. Standard BIAX blade with a negative angle of 3.5° for large chip removal; 0-1° for contorted machine bodies.
Half Moon Patterns
Creates convex areas for oil retention, ensuring lubrication of sliding surfaces. Depth and size depend on tilt angle and blade radius.
Material-Specific Scraping Techniques
  • Gray Cast Iron: Use carbide-tipped blades with a 0-1° angle for large removal.
  • Wax Casting: Adjust cutting angle as needed.
  • High Resistance Steel: Use a steel scraper blade with a 32° angle and 60 mm radius.
  • Cast Steel: Experiment with cutting angles.
  • Non-Ferrous Metals: Use negatively ground carbide-tipped blades.
  • Brass and Red Bronze: Light scraping with negatively ground blades.
  • Aluminium: Use carbide-tipped blades; angle depends on strength.
  • Bronze: Easy to scrape with negatively ground cutters.
  • White Metal: Use BIAX precision scraper with a 20-25° negative angle.
Blade Assortments and Accessories
Includes various blade assortments for different scrapers, half-moon pattern inserts, and standard blades. Accessories include hand scrapers, grinding and lapping machines, and rollers for engineers' blue application.
Technical Data
Accessories include a diamond wheel, abrasive, and sharpening stone. The SKM 80 machine is used for grinding and lapping carbide-tipped blades.

Application Scraping The scraping tool – the influence of various radii and angles on the scraping results The treatment of each workpiece with the scraper begins with prescaping or roughing. In this operations, it is not yet necessary to ensure small bearing points. Therefore, a blade with a large radius is used in order to enable rational working. Blades with a large radius also have a large effective surface with which a wide scrape is obtained. Only after several scraping over and touching up operations do more and more bearing points appear. The blade radius must now be smaller in order...

Operation Scraping 1st Step: Prescraping The part to be trimmel has already been prepared (precision milled, dressed or ground).The first scraping step creates the base. For machine scraping, a blade or scraping insert (25 mm or 30 mm) with a large cutter radius (depending on the size of the workpiece) and a stroke of 12 mm to 20 mm are chosen. The cutter of the scraping tool is placed onto the workpiece at an angle of approx. 45°. The scraper is moved horizontally across the workpiece at a speed that allows the stroke to just overlap. After scraping the complete surface, this procedure is repeated...

Large stroke with BIAX clamp holder KL 130 and BIAX scraping insert 25 x 30 mm. Clean lapped blades increase the smoothness of the scraped surface, simply scraping and prevent marks. Scrape over the surface-over operation, alter the scraping direction so that the scraping tool does not hook into the recesses of the preceding scraping-over operation. Uniform light at the workplace without shadows is important. After scraping and before spotting, remove...

Operation scraping Scraping vertical surfaces Thanks to its unlimited mobility, the new BIAX precision scraper is best suited to scraping vertical surfaces. As the manual scraping of vertical surfaces is linked with physical effort, the effort-saving operation of this device is demonstrated particularly well in this example. It is obvious that time and expense is saved due to lesser physical stressing of the worker. For vertical scraping, the BIAX scraper is used together with a pulley, which, thanks to its method of opera- Influence of different blade radius and tilt angles on the scrapping...

Applications Scraping How to scrap gray cast iron? This material is predominantly used in the production of machine tools. In this case, only carbide-tipped scraper blades and carbide inserts are suitable. If a large amount of material is to be removed, then scrape with a long stroke and a wide blade with a negative cutting angle of 0 – 1°. After obtaining the desired base, you can begin with finishing. How to scrap wax castin? It is easily to scrape this type of cast. It may be necessary to alter the cutting angle of the insert in order to obtain the desired results. How to scrap steel with...
