Studer S40 CNC Cylindrical Grinder

About The Studer S40 Grinder

Studer S40 Grinder: Precision Meets Heavy-Duty Performance The Studer S40 is a robust cylindrical grinding machine produced by Studer, a well-known name in high-precision grinding technology under the umbrella of United Grinding Technologies. Designed for demanding grinding applications across aerospace, automotive, tooling, and general machining sectors, the S40 combines flexibility, accuracy, and rugged industrial construction. At its core, the Studer S40 is a cylindrical grinder capable of grinding external and internal surfaces on workpieces with high precision. It’s used for finishing cylindrical parts — ranging from simple shafts to complex components requiring tight tolerances, smooth finishes, and intricate geometries. Different versions of the S40 have been produced over the years: from basic CNC-controlled S40 models to variants such as the S40-4 and S40-12, each tailored to specific production needs with variations in travel, wheel sizes, and control systems. The S40’s CNC control and high-resolution axes make it suitable for both small batch and high-precision work. With programmable axes, operators can grind complex profiles, tapers, and form geometry with excellent repeatability. The Studer S40 has earned a reputation in manufacturing for durability and precision. Owners and operators often note that while programming takes time to master, the machine’s CNC logic and rigid mechanical design deliver excellent results for cylindrical grinding tasks. The Studer S40 stands as a workhorse in cylindrical grinding — combining precise CNC motion, flexible configurations, and rugged industrial build. Its adaptability for both external and internal grinding tasks makes it a valuable asset in tool rooms and production shops alike, capable of delivering high-quality surface finishes and tight tolerances across a range of applications.
