Mechanisms of subsurface damage and material removal
In accordance with the classification of different grinding speeds, there are three categories used to depict the speed of nanoscale machining: a general grinding speed which is less than 45 m s −1, a high grinding speed of 45-150 m s −1, and an ultra-high grinding speed which is more than 150 m s −1.

High Speed Grinding Performance and Material Removal
This paper reports the high speed grinding performance of silicon nitride using resin bond diamond wheels. The investigation was focused on the effect of wheel speed on material removal mechanisms and ground surface quality. When brittle fracture was prevalent during grinding, surface quality was little affected by wheel speed.

Surface grinding with ultra high speed CBN wheel - ScienceDirect
Dec 01, 1996 · Effectiveness and problems of surface grinding machine with a ultra high speed CBN wheel were experimentally investigated. Diameter of the CBN wheel expands depending on the wheel speed. The value of the wheel expansion is able to be compensated by calculation. Higher surface speed of the wheel results in lower grinding forces.

Whirring/slight grinding noise on acceleration at high speed
Car is a Mk1 Golf with manual 5 speed and 1.8lt engine. When travelling at above 60kph and accelerating or cruising I've noticed a slight whirring, or grinding noise. It almost sounds like a tyre is rubbing against something, thought I am very certain this is not the case (new suspension, tie …
Lateral Crack - an overview | ScienceDirect Topics
The high pressure inside the cylinder acts on the seals to ensure a leak-free sealing by means of a uniform distributed seal contact pressing on the piston rod surface. The contact pressure of the seals on the piston rod surface can be in the range of 50 N/mm 2 at 160 bar system pressure. If a hard particle is imbedded into the seal the contact pressures will be increased by several orders of magnitude.

Tire uniformity - Wikipedia
As the tire rotates it may exert a lateral force on the order of 25 pounds, causing steering pull in one direction. It would be typical for the force to vary up and down from this value. A variation between 22 pounds and 26 pounds would be characterized as a 4-pound lateral force variation, or LFV.
Planet Series High-Speed Air Jig Grinding Spindles
On a lathe, these grinding heads can be used as a precision internal grinder. Special high-speed ball bearings withstand long continuous hours of operation. These spindles exhibit excellent performance for a relatively low cost. Available in four models, each with a particular top end speed rating.
Grinding Feeds and Speeds
The wheel speed, in terms of peripheral speed, is commonly in the range of 5,500 to 6,500 fpm (about 30 to 35 m/sec). High-speed grinding, operating at about twice that speed, is used on specially built surface grinding machines only, which are designed generally for abrasive machining and require appropriately manufactured grinding wheels.
High-speed grinding - Wikipedia
High-speed grinding (HSG) is a rail care concept developed by the company Stahlberg Roensch from Seevetal, Germany. It is based on the principle of rotational grinding and serves to grind rails at up to 100 kilometres per hour (62 mph). Background. Since roughly the beginning of the 1990s, rail network operators have experienced increasing ...
