Cylindrical Grinder
The highly productive S-series of CNC cylindrical internal and external grinding machines offer a wide range of options, fast setting-up and high precision. The highly productive S S-series cylindrical internal and external grinding machine has a wheel head with two external grinding wheels for rough and finish grinding. A range of applications includes any type of cylindrical internal and external machining for automatic production of individual components and series. The modular machine structures, the modern control and programming technique, as well as the grinding technologies, guarantee a high productivity and excellent machining quality.
The S31cnc is available with a distance between centers of 650/1000mm and a center height of 175mm. This machine has now been completed with an additional wheel head version allowing multiple wheel grinding and allows the installation of two motor spindles. Consequently, two diagonally installed grinding wheels, with diameters up to 500mm, can be used. Thanks to the independently programmable drives, these wheels can be adapted optimally for the respective grinding task, guaranteeing a large speed and performance range. The B-axis swivels automatically with a resolution of 0.0001deg so that even the smallest taper angles can be processed with cylindrical grinding wheels to extreme accuracy.
The Studer S32cnc is a fast, accurate and reliable external, cylindrical CNC grinding machine. This cylindrical grinder has chameleon-like properties. Thanks to the large variety of extensions and versions, a large number of applications can be carried out on this machine according to our customer’s requirements. This is possible thanks to X-axis versions at 0deg or 30deg, and the possibility of positioning the grinding wheel on the left or the right side. Thanks to the versatile machine concept, this machine permits a selection of the most suitable grinding method, according to individual customer requirements. Meaning that the machine can master simple and complex tasks in a very high quality accuracy. In the standard version, with the grinding wheel on the right side and a distance between centers of 400mm, this machine is perfectly suited for grinding small and average-sized parts.
In conjunction with the diamond roll dressing attachment, the S32cnc becomes a highly productive machine. Of course, thanks to the proven Studer concept it can be automated with ease. The use of our C axis turns the S32cnc into a high-power plunge grinder. In this context, the hydrostatic guide ways of the X axis play an important role as they allow extremely rapid axes traversing with a minimum of axis lag. Due to the new materials that are emerging in the market, the machining process has to be adapted to the situation. The S32cnc can also master this problem as it can be equipped for high-speed grinding. With a cutting speed of more than 125m/sec, even materials difficult to machine, such as zirconium ceramics or tungsten carbide, can be processed economically.
The Studer S40cnc is a highly productive universal internal and external cylindrical grinding machine. Its range of applications includes any type of external and internal cylindrical grinding task for the automatic production of one-off and series production. The modular machine structures, the modern control and the programming technique as well as the most recent grinding technology guarantee a high productivity and machining quality. The S40cnc is available with distances between centers of 1000 or 1600mm and center heights between 125 and 225mm.
The B-axes is oriented automatically with a resolution of 0.0001deg so that even the smallest taper angle can be ground to the utmost accuracy with, straight grinding wheels. Because of this we show the universality of the machine on a complex chuck element. A measuring system installed on the motor axis of the work head or on the work spindle provides maximum form accuracy of the form during the grinding process. Acceleration and grinding forces are easily absorbed by the dynamic rigidity of the axes drives.
With regard to thread grinding parallel to the axes, the grinding wheel is not swiveled to the pitch angle of the thread, but it remains in the vertical position so that its angle of rotation remains parallel to the Z-axis. Consequently, while grinding the thread there will be a distortion of the profile which is compensated by the Studer software “Studer Thread CNC” to a negligible deviation. By calculating the profile distortion and the automatic generation or optimized dressing programs, thread grinding becomes nearly as simple as plunge grinding or traverse grinding.
