JB04-3, 4, and 5 precision bench presses adopt the combination of worktable, double column and body to realize the closed height adjustable. The length of the double column is determined according to user needs. The closed height has a wide range and is suitable for various heights. Installation of different molds. The improved brake realizes flexible braking, which has better braking effect, avoids vibration during punching, and can ensure the stability of the press. The flywheel rotation is changed from sliding bearing to rolling bearing, which is oil-free, which is conducive to clean production. The new product has applied for a number of patents. The new product is suitable for industries such as electronics, automobiles, terminals, jewelry, lamps, bearings, zippers, etc. It can cut, punch, bend, shallow stretch, riveting and forming metal or non-metal materials.
