5/1/17. Quick Tips #381. Non-sparking tools are made of materials that do not contain iron (non-ferrous metals) and therefore the risk of a spark being created while the tool is in use is reduced. Non-sparking tools protect against both fire and explosion in environments that may contain flammable liquids, vapors, dusts or residues.
1. Introduction. Grinding is regarded as a commonly utilized technology to finish the workpiece's material removal operation on account of its low budget, high precision and strong universality when compared with other machining methods .Different from the wire electrical discharge turning process, grinding always accompanies with the heat relaxation process [2,3].

When grinding, it should be gradually reduced to 0.01-0.003 mm, and 5-6 rounds from smooth knife to sparkless grinding until smooth. If the feed rate is too large and the grinding speed is too high, it will cause the blade annealing and lose the grinding effect, seriously affecting the service life of all-steel blades and the use effect of blades.

A grinding machine, often shortened to grinder, is one of power tools or machine tools used for grinding, it is a type of machining using an abrasive wheel as the cutting tool. Each grain of abrasive on the wheel's surface cuts a small chip from the workpiece via shear deformation.
1) visual inspection. Inspect the surface of the grinding wheel for defects and damage directly with the naked eye or other instruments. 2) acoustic inspection (percussion inspection) The grinding wheel is vertical on the hard ground on the flat (small wheels can be hung by the center hole), using 200-300g weight wooden hammer tapping.
