At the same time, these coolants had to be environmentally friendly and economical on initial purchase price and in use. Grinding machine technology has been advancing by leaps and bounds during the last decade. We found that the only thing available at the time was the same old coolants used by our fathers for the last 30 years.

Cooling during grinding Why do parts need to be cooled during grinding? Grinding is almost always used for the hard-fine machining of metallic parts. Due to the nature of the grinding process, a great deal of heat is generated, particularly in industrial application on CNC grinding machines.To machine parts on CNC grinding machines, a porous grinding wheel with high …

The cooling system of your machine cools the work-piece, reduces the effect of friction, removes heat from the work-zone, and increases rate-of-material-removal, without further damage to the work-piece surface finish. The most commonly used grinding fluids in your machine are water-based emulsions and grinding oils.

I use a flow rate based upon the grinding power created during the process, because the more aggressive a cycle is, the more coolant is applied. With conventional abrasive wheels, a flow rate of 2 gpm/hp is effective. For superabrasive wheels, a flow rate close to 1 gpm/hp (3.8 L/min/hp) works well.

only the point can be used for cutting. •This is done by the holder down at a 15°angle and using a new surface each time the wheel is dressed. •Good supply of coolant should be used when dressing with a diamond, as overheating can cause the diamond to fracture or drop out of its setting. Very light cuts only may be taken with diamond tools.

Principles of Grinding. In all forms of grinding, three different interactions occur between the abrasive and the machined material. Cutting occurs where the abrasive grain is sufficiently exposed to penetrate the workpiece material and curl a chip, and sufficient clearance exists between the grain, bond and workpiece to flush the chip with coolant or throw it away …

Depending on the type of material and the grinding/polishing disk used for preparation, the amounts of lubrication and cooling have to be balanced. Generally, it can be said that soft materials require high amounts of lubricant to avoid damage, but only small amounts of abrasive as there is very little wear on the abrasive.

The synthetic coolants do not transfer heat as well as oils, but the flow possible in grinding applications more than makes up for that. In addition, open grinding such as flat, exposed surfaces throws a great deal of coolant into the air in various size droplets.
