The purpose of this paper is to attempt to give a better understanding of CNC tool grinding, the advantages of CNC ground tools, case histories of actual usage its benefits and its justification.
Compact tool and cutter grinder produces miracles
Launched at Grind Tec, in Germany, a compact CNC tool grinder has the power, strength and working envelope usually attributed to a much larger machine.
This is opening up exciting new opportunities in the medical, aerospace and turbine component manufacturing industries.
Limitations of conventional programming techniques have generally prevented complex contours from being ground.
Milling was the most common process used to create complex components such as turbine blade aerofoils, artificial knee implants and medical tools.

A novel CNC tap grinding machine allows highly efficient manufacturing of taps from a blank to a finished product and all grinding operations including threading are performed in one set-up.
Customised software speeds knee joint machining
Machine and customised software is making significant contributions in quality and productivity to the dynamic and rapid global growth in the field of artificial knee joints.
As new parts have been developed requiring even greater accuracy and surface finish, the need to manufacture to high-precision tolerances meant that a solution for grinding had to be found.
Working together with ANCA engineers, customers supply a 3D computer model, which is then imported into UG (NX3) and a grinding path created.
The data from the path is translated into an NC program via an ANCA post processor program.
The NC program can be loaded onto any ANCA machine that is suitable for the application.
Customers with access to a UG license and the right training can create their own programs by purchasing the post processor from ANCA.
Alternatively, customers can contract ANCA to create the NC grinding program by supplying their 3D model or component details.
Successful testing on contoured medical products showed that grinding not only produced a better surface finish than milling, but also signifcantly reduced manufacturing time.
One component was ground from a blank in under 9 min whereas the traditional milling operation took 2h.
Without the ability to create the NC program via UG, productivity gains like this would have been extremely difficult.
The introduction of 3D CAD-CAM grinding techniques has enabled ANCA and its customers to discover profitible new markets beyond conventional cutting tools.
