We’ve gotten short parts due to the material pulling away from the cutoff when the main goes to start position, and it was usually a barloader issue. Some suggestions: 1. Tighten your main . My job currently uses high pressure coolant flow to shoot the parts out of sub spindle and into the part catcher, but due to various problems with various machines and parts . For most applications and especially for lights-out, ejector pins should be considered for subspindle work to make sure the finished part clears the subspindle before the .

Trust GenSwiss with your Ejector needs. Kits include, ejector base, ejector tips, and stand alone ejector pins that can be used without an ejector base. Quick-change interchangeable tips mate . When parts fail to eject properly from the subspindle of a four-axis lathe or Swiss screw machine, the result can be hours of downtime and a big bill to repair the damage. If you are plagued by this problem, you will be interested in the Subspindle Part Ejection Device (SPED) made by Zenna Industries. This ejector is made up of a hollow rod, 2 bushings and a Dublin rotory coupling, this fits into the back of the sub spindle, the Dublin coupling has a 1/8in pipe connected to it and air or liquid flushes the collet out, the 1/8 pipe also keeps the coupling from rotating and allows the rod to rotate with the sub spindle by means of a bracket.

Sometimes the deformed ejector ends (Deformed in process from wear from rotating chips on the non-rotating ends), become a different shape and stick the part on ejection, drawing it back inside. Then the machine moves to grab a new part and stuffs the non-ejected part into the penumatic actuator. My problem comes on part ejection. Since the ejector spring is loaded as soon as the sub pick up the part, it pushes the part out as soon as it begins to open, thus scratching the part on the way by the collet corner/edge. Anyone run into this before and have a solution?
Right now, I'm using a Hardinge spring loaded part ejector in the sub-spindle. It works ok for short parts, but not so good for longer parts. Is there a better product on the market , or does anyone have a design that would work better?
This is a safety; it prevents stuck pins from dinging the cavity surface on the other side of the mold if the ejector rod won't pull it back. As noted, if the mold has separate cavity inserts, the parting surface is typically set .005 - .010 above the mold plate, to insure the parting line sees full clamp tonnage. We’ve gotten short parts due to the material pulling away from the cutoff when the main goes to start position, and it was usually a barloader issue. Some suggestions: 1. Tighten your main collet up some, to help fight against any pushback. On the Citizens, the high-pressure for the sub is plumbed through the ejector rod; a quick blast would flush the parts out nicely, but DON'T use a pin with a small hole through it unless you want to dig your parts out of the front of the machine. 1500 PSI turns a .
