15.02.2007· We do hard weld turning with these, with fairly good results. For roughing, we use the 1/2" round inserts to knock the humps off, and then change over to 1/32 to 1/8 corner radius inserts to finish turning with. Your lathe needs to be large, maybe a 20" swing machine, and the cross slide screw and nut need to be in good condition with low backlash.

turning and grinding operations. As shown in Fig. 1, the grinding of the hard turned surface causes that regular (deterministic) surface profile generated by hard turning with a small feed rate becomes partly random with deep notches which negatively influence fatigue strength. a) Sa=0.28 Pm, Sz=1.59 Pm b) Sa=0.27 Pm, Sz=3.97 Pm Fig. 2.

Figure 1: Cut-off wheels subjected to improper side grinding. The safety code for grinding and cutting wheels is ANSI B7.1 "Safety Requirements for the Use, Care and Protection of Abrasive Wheels."The code is very specific defining the proper grinding surfaces for each type of wheel and Figure 2 shows that the only acceptable grinding surface on a cutting wheel is on the periphery, not the ...

01.08.2016· Thanks for posting that article, nice to see Hard Turning explained outside of the context of a particular MTB trying to sell you in a particular machine. I liked this bit... Quote of a quote "How the hard-turning process works is simple," says Mr. McCarthy. "If you are finish-turning a shaft of 60 Rc hardness at 400 sfm with an 0.008-inch depth of cut, the material being removed will have an ...

Grinding is especially expensive if a custom wheel has to be made to handle a complex part's geometry. Also, multiple setups often have to be done on the same grinding machine, all of which takes time. Hard part turning is done on one machine, typically in one setup, with standard inserts.

Replacing a traditional process with grinding depends more on how the part and wheel contact each other than on geometry. Similar to the slotting case, another example uses wheel technology, replacing the turning operation with grinding. Newer nickel alloys used in aerospace can be even more difficult to machine than legacy materials such as IN718.
