Scraping requires a lot of effort from the user and can take a long time if the object being scraped is large. Because of this, power scrapers and ‘flakers’ have been developed to speed up the process of scraping and help reduce fatigue.
Power scrapers
Power scrapers can be either electric or pneumatic.
Pneumatic power scrapers are used in applications where there may be a danger of explosion from using electric power scrapers, such as in the chemical industries. The power scraper’s main advantage over a hand scraper is its speed of use. Not only does this enable the user to complete the job quicker, it also reduces fatigue.
Power flakers
Power flakers look the same as power scrapers and can also be electric or pneumatic.
Power flaking is roughly 75% faster than hand flaking, and has several other advantages as well: Power flakers can be used right up to the edges of raised surfaces and get right into corners, as they are pushed instead of pulled. They also make a more uniform flaking pattern and depth than hand flaking.
Differences between power scrapers and power flakers
Whilst they look the same, the movement of the blade is different between power scrapers and flakers. It is this differing movement that enables them to perform different jobs.
Powered scrapers are moved sideways across the workpiece surface by the user, whilst powered flakers are used by pushing the blade forwards over the surface of the workpiece.
