Abstract (English):
A method for a ball blank centerless grinding is considered. A circuit is realized at the expense of the presence helical trapezoidal groove on a drive disk. It is shown that at a ball centerless grinding appears an error of basing on an operation dimension – a diameter of a spherical surface. A setting dimension is defined mathematically during the fulfillment of a technological operation of a ball centerless grinding and also an error of a setting dimension is defined.
