Abstract

The goal of this paper is the development of a precision truing and dressing device for an extremely fine-grit round-profile diamond wheel. A new and compact truer is designed and built to achieve the desired profile without detachment of the diamond wheel from the grinding machine. This 'Arc Truer' has a rotation unit consisting of a silicon carbide cup wheel, and a swing/infeed mechanism for the cup wheel. The truer has the advantage that dressing after truing is not necessary, and that sharp cutting edges protrude from the wheel surface. The profiled wheel is for ductile-regime grinding of aspheric ceramic mirrors. As the wheel is wider than conventional ones for form generation grinding, it is expected that the wheel wear and grinding characteristics will be uniform widthwise. In this paper, a resin bonded diamond wheel is used, and truing tests are carried out with a CNC ultra-precision surface grinding machine. A new grinding method for form generation is proposed and truing characteristics and accuracy of the Arc Truer are investigated.
