In WirecutEDM, every second counts. Your machines should be cutting, not waiting. So why are so many shops still setting up their tools after the machine’s done?
Presetting stones like the RHS-WUS021 are changing that.
They let your team calibrate and set up the next job while the current one is still running—off the machine, on a dedicated granite-mounted reference station. That means no more waiting for a machine to finish before getting to work.
Why Shops Are Moving Setup Off the Machine
Let’s break down what shops are gaining by using presetting stations like the RHS-WUS021:
Nonstop Machining
While one job runs, the next setup gets dialed in—on the side. That way, when the machine finishes, you’re ready to swap in and go. No idle time. No setup delays.
Faster Changeovers
Forget trial-and-error setups at the machine. With a granite-mounted station and dovetail reference system, offsets are locked in and repeatable. Just load and run.
Better Use of Skilled Labor
Why pay a top-tier EDM machinist to stand around waiting for a job to end? Presetting stones let operators prep ahead—so machines stay busy, and people stay productive.
Less Scrap, More Confidence
Manual calibration is error-prone. The RHS-WUS021 provides reliable, rock-solid accuracy that operators can trust—no more cross-your-fingers setups.
Shop-Tested, Operator-Approved
Made to work in the real world, not a lab. Clean design. Simple to mount on a granite plate or CMM. Zero fluff, full function.

Stop Letting Setup Slow You Down
Still using blocks, indicators, or “whatever’s lying around”? It’s costing you more than you think. We’ve seen shops spend 30–60 minutes on a setup that should take 5. Multiply that across every shift, every week… you get the picture.
