1.Drill bit is the key partof gun drill. Due to its unique and scientific combination structure, it plays the role of not only cutwork but also self-orientation, and can create high-precision deep holes through the linear penetration. There are two basic degrees for drill bits, which can be properly combined according to the materials and forms of workpieces to be cut, so as to better balance the cutting force and break chips, and transmit the cutting force to support shoulders to ensure good straightness and axiality. Drill bit has a small backtaper degree and its diameter is slightly large by comparing to the blade, which can guarantee the drill can rotate freely inside the cutting hole and will not rub the cutting surfaces of inside walls of holes. According to different requirements, the blade can be connected to the oil path of blade through the channel with single circular hole, kidney-shaped hole or two circular holes. High pressure coolant can reach the cutting point through this channel, and bring the cutting chips out of workpiece.eometry of drill bit directly affects the performance of gun drill in terms of cutting and processing, and the precision of holes to be processed. Bangyu Company has optimized the following 4 types of peripherally circular drill bits by combining many years of successful experience in manufacturing gun drills. Based on different angles and grinding types, and different workpiece materials and requirements, many kinds of drill bits are available to you. We do believe there always will be a kind suitable for you.
2.Knife bladeis generally designed into the "V" type, with the external diameter slightly smaller than that of drill bit. Under the premise of ensuring sufficient strength and stiffness of blade, the coolant hole and chip removal space should be made as large as possible to facilitate the cooling, lubrication and chip removal of drilling bit part. Bangyu series of blades are rolled down by seamless steel tubes after the heat treatment. Blade has **0 ~ **5 ° of V-type slot, through which the high-pressure cutting coolant will be discharged from the hole after its reaching the grill bit part through the drive handle and aviation oil hole of blade, with the chip taken away. To ensure the straightness and axiality, the blade must have sufficient strength in order to provide the torque required for cutting under less torsional deformation. At the same time, the blade must have sufficient toughness, so as to absorb the vibration generated by high-speed rotation of blade.
3.Driving handleis mainly used to transmit forces. Bangyu Company can provide customers with standard handles categorized into 8 kinds and with 9 specifications. Customers can also customize the non-standard blade handles. They will be produced in full accordance with the provisions of standard industrial process. At the neck position where it connects with the blade, there is a smooth fox-like groove used to eliminate stresses, which can help avoid the damage caused by the stress concentration.
