Diagonal hole processing on a flat plate! Hole processing at a 60° angle can also be handled by pressing!
■This is a product with angled holes for flange installation on pipes. ■A Φ19 hole is drilled at a 60° angle to the top surface. ■Traditionally, due to issues with mold life and quality, angled hole drilling on flat surfaces could only be addressed through machining such as drilling, but our company has achieved this processing solely through pressing. ■Since it is processed by pressing, the processing speed is fast, and there are advantages in maintaining stable quality for hole diameter, hole pitch, and burr height. ■Additionally, unlike drilling, the generation of chips is minimized, so there is no need for burr removal or cleaning after processing. ■This product meets the request for angled holes, but the scrap portion where the angled hole is removed also has a shape with a slope on the outer contour, allowing for applications to meet requests for products with a sloped outer contour.

Applications/Examples of results
■This is a product that responds to your request to install the flange at an angle to the pipe due to space constraints. ■Initially, the customer was considering machining, but since the production would be 20,000 units per month, they requested that we somehow accommodate this with pressing, and we complied. ■At times, we handled up to 35,000 units per month.
