  • Linsheng,Ltd Linsheng Electromechanical Co , Ltd , Gun Drill: 3 Parts Linsheng Electrical Co , Ltd said: The standard gun drill is made up of high-precision silver welding and brazing combined with high-hardness silver welding and brazing of the blade and steel drive handle made of super hard tungsten steel drill blade and aerospace steel. Features are as follows:   Drill blade:   The cutting edge is a key part of the whole gun drill. Its unique and scientific combination structure guarantees the self-guided function while completing the cutting work. It can obtain a high-precision deep hole through one penetration, and the cutting edge has two basic degrees. We can choose the most appropriate combination according to the material and form of the workpiece to be cut, so that the work can better balance the cutting force and chip breaking, and transmit the cutting force to the support shoulder to ensure good straightness and coaxiality. The cutting edge has a small reverse taper and the diameter is slightly larger than the blade body, which can ensure that the drill body can rotate freely in the cutting hole without rubbing the cutting surface of the inner wall of the hole. According to different requirements, the blade has a single round hole and a kidney hole. The passages of the double circular holes are connected to the oil passage of the blade, and the high-pressure coolant can pass through the passage to the cutting point and carry the chips out of the workpiece.   Blade:   The blade body is made of special alloy steel for aerospace industry and is heat-treated. The blade body has a V-shaped groove of 110-120 degrees. The high-pressure cutting coolant passes through the drive handle and the oil hole of the blade body to reach the blade portion, and then exits the hole from the V-shaped groove, and the chip is removed. To ensure the straightness and concentricity of the cutting, the blade must have sufficient strength to provide the torque required for cutting under a small torsional deformation, and the blade must also have sufficient toughness to absorb the high-speed rotation of the blade. The vibration generated.   Drive handle:   The drive handle is manufactured in full compliance with the requirements of standard industrial processing methods. The neck of the blade is provided with a smooth arc-shaped groove for eliminating stress to avoid damage due to stress concentration. The driving handle is cylindrical, and the side surface is generally processed with two planes for the clamping sleeve to lock the entire bit body.

  • mklyk 常见的砂轮问题:问题1:易于使用细粒砂轮将镜面磨削成精细的表面粗糙度。细粒砂轮间隔较窄,碎屑容易堵塞磨粒之间的间隙,造成堵塞。有必要经常修整砂轮以修复碎屑,导致12英寸切割轮磨削效率降低。问题2:发烧灼伤与堵塞有关。当砂轮的孔隙被堵塞时,热量不能被适当地排出,这将导致研磨温度过高,并且砂轮和工件可能已经烧伤。问题3:易产生划痕细粒砂轮的切削力不如粗力,并且耐磨性高。在这种情况下,强力运转刀与上述碎屑和高温一起容易在研磨工件上留下磨蚀痕迹,造成划痕。问题4:易于产生振动如上所述,细粒度的研磨阻力高,并且这种阻力放大了研磨机的振动并且在研磨结果上再现。在镜面研磨中,这种冲击痕迹可以非常明显。问题5:磨削率低,尺寸控制困难磨削阻力加上磨床的振动会导致磨料对工件的冲击过大,造成大的破碎和落砂。砂轮消耗大,磨削率低,磨削精度不易控制,平坦度受到影响。为了保持每个被磨削工件的精度和表面粗糙度,磨削过程的可重复性非常重要,每个磨料人都应该追求。再现性与砂轮,设备和环境等条件有很大关系。烧伤。问题3:易产生划痕细粒砂轮的切削力不如粗力,耐磨性高。在这种情况下,强力运转刀与上述碎屑和高温一起容易在研磨工件上留下磨蚀痕迹,造成划痕。问题4:易于产生振动如上所述,细粒度的研磨阻力高,并且这种阻力放大了研磨机的振动并且在研磨结果上再现。在镜面研磨中,这种冲击痕迹可以非常明显。问题5:磨削率低,尺寸控制困难磨削阻力加上磨床的振动会导致磨料对工件的冲击过大,造成大的破碎和落砂。砂轮消耗大,磨削率低,磨削精度不易控制,平整度受到影响。为了保持每个被磨削工件的精度和表面粗糙度,磨削过程的可重复性非常重要,每个磨料人都应该追求。再现性与砂轮,设备和环境等条件有很大关系。
