The aim of present study is to experimentally investigate and compare the effect of grinding parameters, i.e. downfeed, work velocity and lubricating environments, on the surface integrity of hardened AISI D2 tool steel. The surface integrity of ground surface was evaluated in terms of surface roughness, surface topography, microstructure and microhardness variation. …
In this video I discuss cutter geometry of the turning and facing tool for the lathe and do a demonstration on how to grind them.
For conventional HSS lathe tools the hollow grinding technique described above works well. For threading tools that get lapped using a fixture you can save a huge amount of work by removing unnecessary material at the grinding wheel. You should be lapping the minimum amount of material necessary to the function of the tool.
Tools should be rotated 180-degrees periodically to extend life. Both the single point and chisel point tool should be mounted on a slight angle at the center line of the grinding wheel. Cluster and Multi-Point Tools: Used for straight dressing of …
In internal grinding, abrasive wear occurs rapidly due to the smaller diameter of the wheel. These problems were overcome by interval ELID grinding technique. Two new techniques for internal grinding, namely ELID II and ELID III, are also described in the literature, Figure 7.30. For ELID II, a fixed cylindrical dressing electrode dresses the ...

Grinding – Ex. 1-1 • You are grinding a steel, which has a specific grinding energy (u) of 35 W-s/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW. • The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10.
• Given several standard, common grinding jobs, recommend the appropriate abrasive, approximate grit size, grade, and bond. The Surface Grinder is mainly used in the finishing process. It is a very precise tool which uses a stationary, abrasive, rotating wheel to shave or finish a metallic surface which is held in place by a vise.
