Automatic greasing device for chuck in crankshaft miller

Abstract

To provide an automatic chuck greasing device in a crankshaft miller capable of ensuring chuck greasing without missing its timing and preventing failure to remove excess grease by wiping. In a crankshaft miller () which cuts, using a rotary cutter (), a workpiece () held by a chuck (), the automatic greasing device includes: a grease supply device () for supplying grease to sliding parts inside a chuck () including one between a chuck body () and a chuck jaw () in response to a greasing command signal outputted by a greasing command signal output unit () which has received a rotary cutter replacement command signal as a trigger signal from a rotary cutter replacement command signal output unit (); and a notification means () for notifying that a cutter () needs replacement in response to a notification command signal outputted by a notification command signal output unit () which has received the rotary cutter replacement command signal as the trigger signal from a rotary cutter replacement command signal output unit ().
