When Does Hard Turn/Grind Make Sense? Modern

15/04/2002  As one might expect, turning machine builder Index and grinding machine maker Junker approach the designing and building of their hard turning/grinding machine tools differently. While the production goals are the same, these companies' machines illustrate just two of a wide variety of ways that machines can be configured to accomplish the general multi-processing task of hard turning and ...

Soft Turning Is Key To Hard Turning Modern Machine Shop

"With single-point hard turning we make one or two passes and it's done." Applications for hard turning tend to be workpieces with complex geometries. A CNC turning center's programmability will usually out-perform a grinding machine even though the lathe usually makes multiple passes. A CNC turning center can create a contour by programming. A cycle time differential between it and grinding ...

The process combination hard turning / grinding is used, to great effect, to reduce cycle times. Where the complete hard finishing process (hard turning and grinding) is carried out on a single machine, throughput, transport and storage times can be drastically reduced. There are also advantages in the reduction of setup efforts and setting times.

Soft Turning Is Key To Hard Turning Modern Machine

Hard turning allows a shop to turn, heat treat and then hard turn to final size and surface finish specifications. Most contemporary CNC lathes are capable of hard turning so shops conceivably can soft and hard turn on the same machine. Still, there are many jobs that make sense to grind. Some geometric configurations and very low surface finish requirements remain in the purview of grinding. Increasingly though, applications that were automatically given to a grinding machine

Taking The Fear Out Of Hard Turning Modern

The greatest advantage to hard turning, however, is that it eliminates a grinding operation to finish the part. Therein lies the payoff that makes hard turning such an attractive alternative to many machine shops. So why isn't everybody doing it? Obviously, hard turning is not an option in every case, but not every application for hard turning is being taken advantage of. One reason is that some potential

Turning - Wikipedia

Hard turning Hard turning is a type of turning done on materials with a Rockwell C hardness greater than 45. It is typically performed after the workpiece is heat treated. The process is intended to replace or limit traditional grinding operations. Hard turning, when applied for purely stock removal purposes, competes favorably with rough grinding. However, when it is applied for finishing where form and dimension are critical, grinding is superior. Grinding

Eccentric turning becoming conventional work

That’s a bit of a pain because you spend more setup time or move the part to a second machine. Having a modern multitasking machine like the Multus saves you from moving to another machine. It’s not a silver bullet, but there are cases when it can prevent a major headache. If I had a large part and the majority of it needed eccentric turning, I would probably use two separate machine ...
