Hand Scraping

While many call hand scraping a lost art, at Okuma we beg to differ. While it might be rare to find a craftsman skilled enough to hand scrape effectively, we never lost the art simply because we’ve always understood how critical hand scraping is to maintaining machining accuracy. To ensure tight tolerances, mated components require a meticulous attention to detail that only a hand scraper can deliver. A skilled hand scraper will place and remove components multiple times, scraping away—using a variety of techniques—until each piece is mated perfectly. And while hand scraping is typically associated with mated surfaces, it’s crucial for bolted surfaces, too. Hand scraping is one of the keys to Okuma’s legendary accuracy, and is also one of the secrets behind the unparalleled longevity of our machining centers, as well as grinder and lathe components. Of course, it makes sense once you realize the level of detail that goes into ensuring that each component fits ideally from the
