Rapid Holding Systems: Faster EDM Setups, Lower Costs — The Complete System 3R-Compatible User Kit

If you’ve been running WEDM for a while, you know how frustrating slow setups and alignment issues can be. 
 
Every extra minute spent adjusting tooling is a minute your machine isn’t cutting — and when you’re using OEM System 3R components, those delays can be costly in more ways than one. 
At Rapid Holding Systems, we designed the System 3R 3R-242.82HP Compatible User Kit to give you quick, precise, and repeatable positioning without the long lead times or high costs of OEM parts. 
Most of our customers face the same set of frustrations in their WEDM workflows: 
Slow setups, alignment issues that cause scrap and rework, and long waits (with high costs) for OEM System 3R components. 
Standard setups get the job done, but they’re rarely fast. Every extra adjustment is lost production time, and when you’re relying on precision tooling, even small delays can throw off delivery schedules. 
Shops running demanding EDM workflows need a faster, smarter alternative.
