摘要： PURPOSE: An apparatus for cutting off an unnecessary object deposited on a casting is provided to reduce the amount of diamond tip used, achieve an energy-saving for a cutting power and reduce the amount of chips produced upon the cutting of the unnecessary object. CONSTITUTION: The apparatus for cutting off an unnecessary object deposited on a casting includes a motor having a rotary shaft(3) adapted to be rotated at a high speed, and a disk-shaped diamond tip saw(2) mounted at a tip end(4) of the rotary shaft(3) and adapted to be rotated by the rotation of the rotary shaft(3) to cut off the unnecessary object(9) on the casting(8), so that the tip saw(2) is rotated at a rotational speed in a range of 6,000 rpm to 8,000 rpm. Thus, the rigidity of the diamond tip saw(2) rotated at the high speed is increased by a centrifugal force provided by the diamond tip saw(2) itself and a gyroscopic moment effect to reduce the thickness of the diamond tip saw(2) is reduced by a value corresponding to an increment in rigidity of the tip saw(2).
摘要翻译：目的：提供一种用于切割沉积在铸件上的不必要物体的装置，以减少所使用的金刚石尖端的数量，实现切割功率的节能，并减少切割不需要物体时产生的切屑量。构成：用于切除沉积在铸件上的不必要物体的装置包括具有适于高速旋转的旋转轴（3）的电动机和安装在顶端的盘形金刚石尖锯（2）旋转轴（3）的旋转轴（4），并通过旋转轴（3）的旋转而旋转，以切断铸件（8）上的不需要的物体（9），使得尖端锯（2）旋转在6,000rpm至8,000rpm的范围内的转速。因此，通过由金刚石尖端锯（2）本身提供的离心力，提高高速旋转的金刚石尖端锯（2）的刚度和减小金刚石尖锯（2）的厚度的陀螺力矩效应，减小与尖端锯（2）的刚性增加相对应的值。
