摘要： PURPOSE:To easily conduct a test in a short time by clamping a sphere to be tested so that the axis of rotation of a sphere holding shaft runs in the center of the sphere to be tested, and placing a load and further rotating the sphere. CONSTITUTION:The sphere 2 to be tested which is clamped between sphere support shafts 1a and 1b and is loaded between a driving roller 4 and a driven roller 7 rotates by receiving a frictional force by the rotation of the driving roller 4. Simultaneously, the driven roller 7 also rotates by receiving a frictional force from the sphere 2 to be tested. Thus, the sphere 2 to be tested rolls between the driving roller 4 and driven roller 7 and rolling friction increases at the equator part in contact with them. During this period, the sphere 2 to be tested and driven roller 7 follow up the friction to move toward the driving roller 4 by the load from a loading device 11 according to sphere holding base guide rods 9a and 9b and a guide means such as a ball slide unit, so that the sphere 2 to be tested is applied with an invariably constant load.

摘要： PURPOSE:To considerably improve polishing coefficient by providing a lower-part rotary disc, which is mounted at the upper part of a high-speed rotating turbine shaft and constructed so as to be pushed up in a casing by gas pressure to have rotated a turbine. CONSTITUTION:If a polished sphere 2 is inserted in between a lower-part shaft 3 and an upper-part lap disc 1, lap liquid 10 containing grains is filled therein so that the polished sphere 2 can be completely immersed and gas (usually air) is delivered therein through a gas delivery pipe 8, then a turbine 6 rotates at a high speed. A lower-part rotary disc 3 which is connected to a turbine shaft 7 rotates therewith at a high speed, and is pushed up in a casing 5 due to piston effect by gas pressure to have rotated the turbine 6, so that the polished sphere 2 is pushed against the upper-part lap disc 1. So, the upper-part lap disc 1 is rotated by a separate driving source (motor) 9 to polish the polished sphere 2 in sphericity.
