Abstract:
1. A method for producing one or more tools on a circular grinding machine, said circular grinding machine including a workpiece spindle head and a tailstock, said method comprising the following steps: obtaining a round rod, a length of said round rod being a multiple of a length of an individual tool; positioning said round rod through said workpiece spindle head and gripping said round rod in a chuck of said workpiece spindle head, an outwardly projecting end region of said round rod outwardly projecting from said workpiece spindle head and facing 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 face of said outwardly projecting end region of said round rod; fitting and clamping said first end face taper in a hollow center punch, said 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 of said individual tool; cutting off said individual tool from said round rod; releasing said chuck of said workpiece spindle head; 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, wherein said cutting off said individual tool ground on said outwardly projecting end region of said round rod, includes: retracting and axially displacing a grinding wheel relative to said round rod; grinding a second end face taper into said round rod on another end face at an end of said individual tool opposite said first end face taper; grinding a separating cut into said round rod so that a central connecting band remains in said round rod connecting said individual tool to said round rod; and grinding off said connecting band and removing said individual tool.
