Yahoo AnswersMay 25, 2008查看更多结果Jun 15, 2016· Force control technology is important in the grinding system. In the grinding process, grinding force is a pressure in a specified direction which is applied to the surface of the mold by polishing tools. The force should be controlled in some stable value to ensure the grinding quality.

Dec 14, 2005· As grinding forces are applied to the work-piece specimen, deformation in the quartz in the force sensor causes a charge release. The charge amplifier magnifies the charge signals and converts these signals into voltage signals.

Grinding Wheel Speed Calculator: All Norton grinding wheels are marked with a maximum operating speed in RPM. Most machines, and especially CNC machines, use Surface Feet Per Minute (SFPM) as an input, which requires operators to do the conversion.

Jun 17, 2008· A 55.0-kg grindstone is a solid disk 0.520 m in diameter. You press an ax down on the rim with a normal force of 160 N View Figure . The coefficient of kinetic friction between the blade and the stone is 0.60, and there is a constant friction torque of 6.50 N*m between the axle of the stone and its bearings. How much force must be applied tangentially at the end of a crank handle 0.500 m long

May 26, 2008· A grinding wheel is initially at rest. A constant external torque of 50.0 N · m is applied to the wheel for 20.0 s, giving the wheel an angular speed of 600 rev/min. The external torque is then removed, and the wheel comes to rest 120 s later. Find (a) the moment of inertia of the wheel, and (b) the frictional torque, which is assumed to be constant.

Depending on the application, lowering the angle of attack could make for more efficient grinding, especially if applied force can be increased. In fact, with the latest abrasive media, the increased contact area reduces process time and, with the correct applied force, could wear the abrasive so that it fractures the abrasive grain, revealing

A large grinding wheel in the shape of a solid cylinder of radius 0.330 m is free to rotate on a frictionless, vertical axle. A constant tangential force of 280 N applied to its edge causes the wheel to have an angular acceleration of 1.120 rad/s2.

Mar 15, 2003· A result of rotary motion, centrifugal force is what causes a weight on the end of a string to pull the string taught when the weight is swung in a circle. This same force causes the mass of the grinding wheel to be pulled outward from the center of rotation as the wheel is spinning.
