摘要

The fixed roller assembly, to roll the plunge-cuts in a crankshaft at the bearing mounting points, has a flexible feed line for lubricants or an air/lubricant mixture, between the ends of two scissor arms, between the housings of the fixed rollers. The flexible channel is between a channel through one scissor arm and the channel of a support roller head.
