<p>[QUOTE="usmc60, post: 2416293, member: 76739"]Sir in the old printing process you are absolutely correct. But with the modernization of the printing process it is my understanding the newer equipment was to not have to have a lot of maintenance such as sealed grease list bearings. And the only possible means of any oil contamination would come from the hydraulic piston seal failure as indicated in the photo I'm going to show you. And on top is the planchet feeding tube. This is a MRH 150 high-speed coinage press. And it looks like the planchet loading tube is Teflon coated and would not require any kind of lubrication at all. YouTube has a video of this bad boy in action Enjoy.<img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie50" alt=":happy:" unselectable="on" unselectable="on" /><img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie50" alt=":happy:" unselectable="on" unselectable="on" /><img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie24" alt=":blackalien:" unselectable="on" unselectable="on" />[ATTACH=full]500044[/ATTACH][/QUOTE]</p><p><br /></p>
