Faster Setup for Centerless Grinders
The new series of Jupiter centerless cylindrical grinding machines from Erwin Junker Machinery (Elgin, Illinois) addresses the limitations to applying this process to small- to medium-sized batches.

Cylindrical Grinding Machine Features Three Spindles
Junker’s all-round machine series features a high-precision B axis with automatic stepless positioning for versatility, while three high-performance spindles enable ID and OD grinding operations.

When Does Hard Turn/Grind Make Sense?
Combining different operations on a single machine tool platform is an attractive and increasingly popular idea. It is in practice, however, not always a plug and play substitution. Optimizing distinct metalcutting operations into a single cycle takes planning and a good understanding of the pluses and minuses of each.

One Stop Milling, Drilling, Turning And Grinding
Many shops, in an effort to reduce the handling of workpieces and get takt times (time spent in the cut) as low as possible, are looking to streamline this traditional hurry-up-and-wait process scheme.

What Is Single Point OD Grinding?
Two enabling technologies -- superabrasive wheels and high precision servo control -- come together to provide a contour grinding process that resembles an OD turning operation. For many medium volume OD grinding applications, this method may be a means to consolidate several manufacturing steps into a single setup.
