MODEL DPH-400W 4 INCH DIAMETER DIAPHRAGM CHUCK

Description

Model DPH-400W 4 inch diameter diaphragm chucks feature special jaws and stops. The stops have 3 small “Air Detect” holes for part seating conformation. Air is pumped through these holes, and when the part rests on the stop, the air pressure rises, tripping a pressure switch telling the machine to start machining. The 4
clover adapters have grooves for a CAM follower to snap into to orient the chuck when stopped.
Up top is an eight passage rotary union to actuate all four chucks independently. These are
mounted to a 4 spindle Theilenhaus machine.
Northfield Precision designs and manufactures the world’s most accurate air and diaphragm
chucks for any lathe, boring machine, grinder or VMC. Models include through-hole, high-speed
and quick-change. Available in SAE or metric, in sizes from 3” (76mm) to 18” (457mm).
Accuracies of 0.001” to 0.00001” (0.254m) guaranteed.
