Centerless Grinding. Centerless Grinding is so named because it removes material without the use of a spindle. Centerless grinding is accomplished by placing the tubing or rod on a work rest that positions it between a regulating wheel that spins the stock in one direction, and a grinding wheel that spins in the opposite direction.

This work presents an analytical cutting force modeling for micro-slot grinding. Contribution of the work lies in the consideration of both primary and secondary tool surface interactions with the work surface as compared to the previous works where only primary tool surface interaction was considered during cutting force modeling.

In the machining world, turning tools such as lathes and mills are the flashy stars. In fact, they are machining to most people.However, the ability to do precision centerless grinding in addition to machining is a definite advantage.. How does centerless grinding work? Centerless grinding is one of several machining processes that use abrasive cutting to remove material from a part (workpiece).

Grinding forces are a key parameter in the grinding process, most previous studies on grinding forces, however, (i) were regardless of grain-workpiece micro interaction statuses and (ii) could only predict average/maximal grinding forces based on average/maximal cutting depths or chip thicknesses.

The experimental results show that nanofluid MQL is effective for reducing grinding forces and enhancing surface quality. In addition, it is demonstrated that the type, size and volumetric concentration of nanoparticles are critical parameters to have influence on the performances of micro-grinding process.

Grinding and polishing is the final stage in the metallographic sample preparation process and consists of several steps. Each step uses finer abrasive than the previous one, the ultimate goal being to produce a deformation-free, scratch-free and highly reflective sample surface. The sample may need to be examined, either etched or unetched, to ...
