Gap between plunger and barrel
Hi.I am just a guy trying to build an injection machine.It have been running pretty smooth so far,but i ve encountered a problem.I want to order a plunder for a local lathe man,but i cant define a gap between the plunger and the barrel.I have to come up with something in order not to smoothen the barrel inside.That would be far too expensive for me.How do i make a valid order?
hi there, i made mine on the lathe from brass. turned it down till it fitted snug and works well i can send pic for you .
Brass?Thats a strange choice because it has a strong linear thermo expansion.Why dont you use steel?
Could you tell me the exact value?
