Abrasive Machining and Finishing Operations • There are many situations where the processes of manufacturing we’ve learned about cannot produce the required dimensional accuracy and/or surface finish. Fine finishes on ball/roller bearings, pistons, valves, gears, cams, etc. The best methods for producing such accuracyget price
Feb 01, 2010 Abrasive machining can take the place of “large-chip” machining processes like milling, planing, broaching, and turning. Compare the surface finish and the precision achieved with the large-chip processes to the surface finish and precision achieved by abrasive machining, and there is no comparison—abrasive machining is far superior.get price
• The greater the surface-finish, the more operations involved, increases the product cost. • Abrasive processes and finishing processes are important to include in the design analysis for pieces requiring a surface finish and dimensional accuracy. • Creep-feed grinding is an economical alternative to other machining operations.get price
Abrasive machining is a machining process where material is removed from a workpiece using a multitude of small abrasive particles. Common examples include grinding, honing, and polishing. Abrasive processes are usually expensive, but capable of tighter tolerances and better surface finish than other machining processesget price
Finishing operations are carried out at low feeds and depths feeds of 0.0125–0.04 mm/rev (0.0005–0.0015 in/rev) and depths of 0.75–2.0 mm (0.030–0.075 in) are typical. Cutting speeds are lower in roughing than in finishing. A cutting fluid is often applied to the machining operation to cool and lubricate the cutting toolget price
