Studer S122 cylindrical grinder

SKU: S 122
Studer S122 cylindrical grinder The Studer S122 is a powerful, production CNC grinder designed for internal cylindrical grinding of small and medium-sized workpieces during high-volume production. The machine can process workpieces up to 220 mm in diameter and 120 mm in length, with a longitudinal grinding range of up to 110 mm. The S122 can be configured with three parallel-mounted grinding spindles, one of which can handle an external grinding wheel. This allows for rapid switching between different types of operations in a single cycle, significantly increasing workflow and saving time in high-volume production. The precision of the Studer S122 is based on a rigid bed cast from Granitan® material and the advanced StuderGuide® guide system for the X and Z axes – these solutions guarantee constant stability, minimize vibrations and improve the quality of the finished part. Key Features of the Studer S122: Part diameter: up to 220 mm, Part length: up to 120 mm, Longitudinal grinding range: up to 110 mm, Up to 3 grinding spindles in parallel configuration (one with external grinding wheel), Granitan® bed – durability and process stability, StuderGuide® – precision X and Z axis guides, Designed for large-scale production of small and medium-sized parts, High accuracy and quality of finish.

FAQ

What is the Studer S122 and what is it used for?
The Studer S122 is a powerful CNC grinding machine for production internal cylindrical grinding of small and medium-sized workpieces, designed for both small and large-scale production. The manufacturer emphasizes that this machine is designed for "small bores."
What are the basic parameters of the S122?
The machine has a 220 mm throughput diameter, processes workpieces up to 120 mm long, and offers a maximum longitudinal grinding range of 110 mm. The documentation also specifies a machining area diameter of up to 70 mm and a workpiece weight of up to 3 kg.
What makes spindle configuration unique?
The S122 can have up to three grinding spindles in parallel, one of which can handle an external grinding wheel. This allows for internal and external grinding in a single setup.
What is the importance of Granitan® and StuderGuide®?
The Granitan® S103 bed provides excellent vibration damping and thermal stability, while the StuderGuide® guide system for the X and Z axes increases accuracy and load capacity. This combination is the foundation of the S122's high precision.
What does the control and operation look like?
The S122 is equipped with a Fanuc 31i-B control with an integrated PC and a 15-inch touchscreen for easy programming and operation. The StuderWIN system helps maintain a stable programming environment and simplify operator work.
Is the S122 suitable for automation?
Yes, the manufacturer's documentation describes the possibility of full integration of process measurement, process control sensors, and contact detection and balancing systems. This supports batch production and cycle standardization.
What applications is the S122 best for?
The S122 is designed for machining small and medium-sized parts in high-volume production, particularly where high productivity and repeatability are essential. It is suitable for applications requiring precision grinding of small holes.
Why is the S122 a good production choice?
Combining high productivity, multi-spindle capability, and a robust design, it performs well in intensive mass production. The manufacturer positions it as a compact yet highly efficient machine.
