S151 - The Powerful for large and complex
workpieces
The Studer S151 CNC universal
internal grinding machine with its very broad working range, this
powerful compactly designed machine permits internal and external
grinding of workpieces up to 300mm (11.8") in diameter. The large
accommodating capacity of the sturdy workhead and the spindle
turret with up to 4 grinding spindles opens up a wide range of
possible applications, making the S151 suitable for complete machining in
one set-up.
This exceptionally precise and efficient CNC
universal grinding machine has been specially developed for
individual components and small series production operations. The
beneficial price-performance ratio means lower part costs.
Have a look at the short video
below to get an idea of the flexibility of the Studer S151 when
used for applications which require internal and external grinding
in the same clamping.
