Profile & Creep-Feed-Grinding Machines
Peter Wolters Precision Solutions (India) Pvt Ltd offers Profile and Creep-Feed-Grinding Machines, Macro and Macro-L. The “Macro†machine range is based on the innovative moving-wheel-head (MWH) concept. All linear movements when positioning and grinding are performed by the grinding head. Compared to conventional moving column and moving table concepts this design arranges the axes in a very compact way, which results in optimum force distribution and minimal thermal variation, properties which result in best possible process control over a long lifespan. “Macro†machines are used in almost every industrial sector in which precision mechanical components are found. Wherever there is a need for accurate profiles or slots and/or close finish requirements micron equipment offers excellent, economical results. In the aircraft engine and stationary turbine industries, components with poor machinability, such as turbine blades and vanes, can be ground efficiently. Further applications are the highly efficient production of linear guide components, saw tooth profiles, gear racks, gear rings, guides, work holding details, cutting tools, broaches and highly dense ceramic parts. Steering system components and rocker arms are machined in the automotive industry. Stators and rotors in the hydraulic industry are other areas of application. The standard “Macro†creep feed grinder provides X-travel up to 600 mm long. The torque tube design machine base guarantees superior vibration dampening and thermal stability. Spindles are available with different speed and power ranges to best match the application. All spindles feature liquid cooled motors, and high speed HEDG spindles offer liquid cooled bearing packs as well. This further enhances thermal behaviour and consistent production results. The machine is equipped with precision linear guide ways, ball screws, and digital drives in all axes. The state-of-the-art Siemens 840D CNC control allows precision contour dressing and grinding and offers up to 5-axis interpolation.
