Haven Manufacturing, the world leader in dual-blade shear cut-off technology, offers a series of products ideally suited to satisfy a wide variety of applications for metal tube cut-to-length processing. Haven’s unique Dual-Blade Shear Cut-Off machines are designed to automatically and rapidly cut round, square, and irregular-shaped tubing to precise lengths. Dual-blade shear cutting is a series of two mechanically synchronized steps, referred to as “nick and shear”. First, a horizontal “nick” blade shaves a flat groove across the top of the tube. Second, a vertical “shear” blade pierces this groove and shears through the tube. Additional operations include a loading system to supply new mill length tubes and a tube feeder system that advances the tube to a stop mechanism.
As dual-blade shear tube cutting is a two stage process, a mechanical link keeps the horizontal blade clear of the vertical blade. The horizontal cut removes approximately 50% of the tube wall thickness, preventing the downward force of the vertical cut from distorting the tube’s shape. Next, the vertical blade parts the tube by entering through the scarf on top and shears the tube clean. The tube wall is collapsed onto itself and the continuing downward pressure pushes the material until it clears the tube. This process yields minimal burr and, contrary to rotary saw cuts, leaves no metal filings that must be removed. Haven’s Dual-Blade Shear Control system utilizes internationally recognized machine control technologies and is easily set up and operated. The touch screen display and intuitive menus enable command execution and simple configuring.
Haven manufactures a full line of tube cutting and processing equipment. Our Dual-Blade Shear and Supported Shear technologies are globally recognized as the most reliable and efficient products on the market.
