Precision optic polishing machine SLP 301

CNCspherical

Introducing the Spheroline® SLP 301 Very high form accuracy and reproducibility – the SLP 301 guarantees these desired polishing characteristics for optics with a polishing tool up to 480 mm. High-Performance digital spindle drives, mounted on a very stiff machine base, effortlessly provide the necessary torque and ensure low processing times. Unique for a machine of this class, the correction and polishing spindles are arranged in line ensuring very accurate correction without a tool change. The capabilities of the SLP 301 don’t end with polishing of spheres. An optional asphere package extends the processing range to the world of aspheres resulting in a single solution for virtually any requirement. Solid foundation The machine is built around a very stiff cast iron base for kinematics of 4 axes and 3 spindles. The tools are changed with the hydro expansion technology. The modern CNC controller system directs the AC servo drives ensuring consistently high accuracy during the polishing and correction. The controller checks and adjusts all parameters like process times, working pressures, oscillation speed of the polishing process etc. Multi-step processing can be performed and parameters can be individually adjusted. A park position of the workpiece spindle as well as the front- and top-opening of the machine housing enable an easy change of heavy polishing tools by crane loading. One step ahead The polisher comes with one polishing spindle opposite the workpiece and the correction spindles which are arranged in parallel. This arrangement enables the correction and the polishing step without any tool change.
