The Lean Selection shaft is an economical machine concept for grinding flutes and flat surfaces and for diameter machining with multiple grinding wheels. It grinds in combined operations in straight and/or in angled infeed operations. Highlights Rough and finish grinding in a single clamping set-up, saving time and increasing accuracy. High rate of utilization thanks to CBN abrasive and oil (optionally emulsion) as a coolant. Proven CBN grinding technology with cutting speeds of up to 140 m/s and high feed rates, resulting in short cycle times. JUNKER 3-point mounting interface for fast changeover and excellent grinding wheel concentricity. HF high-power grinding spindle (42 kW drive capacity) is extremely low-maintenance thanks to lifetime lubrication and air seal. Ergonomical machine concept with automatic or manual loading from above. Sophisticated, high-performance, user-friendly CNC controls. The work piece program can be created directly at the controller or at an external programming station. High dimensional accuracy due to in-process measurement. Equipment and Options CONTROL SYSTEM The Erwin Junker Operator Panel was specifically developed to control grinding machines. All machine components are controlled using the operator panel – irrespective of the series and the used control system. The identical structure, intuitive menu guidance and visualization of the workpiece geometry make for extreme user convenience and flexibility in operation. Programming takes place directly using the operator panel or an external programming tool.
