Thread cutting chuck EMUGE FRANKEN

Series KSN

The tap holders of our KSN series are designed especially for use in CNC machining centers, CNC turning machines and other machine tools. The tap holders type KSN/Softsynchro are mainly used in CNC machines with synchronous spindles, due to their special constructional design. Owing to the very different requirements a tap holder has to meet, the KSN series can be divided into the following six types:

KSN for conventional thread cutting, marked with a yellow ring on the shell.

KSN/IKZ(Z)/MMS for thread cutting operations with internal coolant supply and minimum quantity lubrication (MMS) up to 10 bar (140 psi), marked with a green ring on the shell.

KSN/HD for thread cutting operations with internal coolant supply up to 50 bar (700 psi); marked with a red ring on the shell.

KSN/ICS for thread cutting with control of the thread cutting cycle.

KSN/Synchro for thread cutting on machines with a synchronous control system, for tap clamping with steel collets.

KSN/Softsynchro By installing a minimum length compensation on compression and on tension, small pitch differences between spindle and tap which would lead to high friction forces on the thread flank are compensated. An eventual increase of axial force during the thread cutting cycle is reduced to a minimum.
