Coolant flow in surface grinding with non-porous wheels. ... Abstract. A parameter that is often used in the assessment of cooling efficiency in grinding is the amount of fluid that flows through the grinding zone. This paper shows that when grinding with wheels possessing no bulk porosity, only a portion of the flow through the grinding zone ...

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 …

µm roughness is achievable with surface grinding for all ferrous and non-ferrous alloys. Parameters to be considered are cutting speed, feed rate, MRR, depth of cut, coolant flow rate. Physical properties are grain size for both material and tool and grit size for grinding wheel and its structure of material (course and fine).

In several studies heat distribution factors have been estimated for different grinding processes (Refs.17–22). The evaluation of these papers shows that up to 80% of the thermal energy can flow into the workpiece. For surface grinding of unhardened steel a heat distribution factor KW = 0.65 was determined (Ref. 19).

Flow rates from these nozzles can range from 2 to 50 gpm (7.6 to 189.3 L/min.) at 4,000 psi. The ¼ MEG marking on the nozzle means a ¼" NPT thread is used to attach the nozzle to a machine. By effectively applying coolant when grinding, end users should find the metal removal process to be less abrasive.

To quench the grinding spark a secondary coolant line to direct a flow of grinding oil below the grinding wheel is recommended. Broaching : For steel, a heavy mineral oil such as sulfurized oil of 300 to 500 Saybolt viscosity at 100°F (38°C) can be used to provide adequate lubricating effect and a dampening of the shock loads.

For non-patterned grinding wheels the coolant flow rate stays almost constant at about 2.1 l/min, when changing the sample width. When grinding with patterned grinding wheels the flow rate through the contact zone is about 20% higher, but stays almost constant as well at about 2.5 l/min.

The first or upper jet disrupts the air curtain and so a vacuum is formed allowing an abrupt flow of coolant into the grinding zone. The second and middle orifice supplies the cutting fluid that leads to the formation of a coolant coating on the grinding wheel. The final and third orifice directly sends the cutting fluid into the grinding zone.
