The newest member of the STUDER family has arrived in the form of the S23, a cylindrical grinding machine that is equally well suited for flexible HMLV (high-mix, low volume) production in smaller shops and high-volume production in large scale operations. Built with impeccable design and patented technology, it guarantees excellent accuracy and cylindricity across the entire workpiece.

The new machine is touring a handful of U.S. locations this summer and fall during the Route S23 Road Show. You can learn more and RSVP for that event, and here’s what you can expect:

About that Granitan base:

Our proprietary technology starts with a mixture of selected aggregates and epoxy resin, which is processed using a cold-casting method and cures within a day to form a highly stable machine base. As a result, STUDER shops enjoy damping properties that are 6 to 8 times better, thermal stability that brings higher surface quality and a sustainable, energy-efficient manufacturing process.

Software and Operating System

StuderWIN and C.O.R.E. team up to bring industry-leading capability and ease of use to high-precision cylindrical grinding. Expect quick and easy programming of complex processes, backed by over a century of grinding history, and technology that feels both groundbreaking and familiar all at once. It’s a perfect fit for the modern machinist.

Completely Future-Forward

Inside the S23 footprint are features and components that are beautifully designed and perfectly executed. From automation readiness to SmartJet™ coolant supply to the famous dresser, tailstock, workhead, internal grinding spindle and dressing spindles, this is a machine that you’ll be able to count on not just for years, but for decades to come.
