Claim:
A method for producing one more sintered hard metal tools on a circular grinding machine, said circular grinding machine including a workpiece spindle head and a tailstock, said method comprising the following steps: providing a round rod formed of sintered hard metal, a length of said round rod being a multiple of a length of an individual tool; positioning said round rod through said spindle head; and chucking said round rod in a chuck of said workpiece spindle head such that an outwardly projecting end region of said round rod outwardly projects from said workpiece spindle head and faces said tailstock; executing processing including: grinding a steady rest on said outwardly projecting end region of said round rod and placing a steady on said steady rest; grinding a first end face taper on an end race of said outwardly projecting end region of said round rod; fitting and clamping said first end face taper in a hollow center punch, said hollow center punch being located on a sleeve of said tailstock; circular grinding said outwardly projecting end region of said round rod to a circular ground final contour over a length that defines the individual tool daring said round rod being chucked by said chucking; gripping said outwardly projecting end region using a gripping unit after said circular grinding; cutting off said individual tool from said round rod during said gripping; removing said individual tool from the machine by operation of said gripping unit after said cuffing off; releasing said chuck of said workpiece spindle head after said removing said individual tool; and moving said round rod in said workpiece spindle head toward said tailstock; and clamping said chuck such that a further outwardly projecting end region of said round rod is outwardly projecting from said workpiece spindle head and facing said tailstock and is processed according to said processing.
