Years ago I acquired a Marquart Neck Turning tool to be used with my modified neck turning mandrels. While I used the same major shank size as the Marquart unit, I made up special stainless steel mandrels conforming to sized case neck shank diameter.
Users also have the option of purchasing additional mandrels for non-cylindrical containers.
The first tool is usually a flat metal plate with a half round groove cut out (diameter of mandrel + flex thickness + a few extra mils).
Then push the mandrel shaft and neck-turning fixture to the right until the case mouth and tip of the mandrel are separated by about 0.125 inch.
[12] investigated the effects of rolling parameters on PEEQ and temperature distributions in radial-axial ring rolling process and declared that, with the increase of the mandrel feed rate and the initial temperature of ring blank, the PEEQ and temperature distributions of rolled ring become more uniform.
where [V.sub.c] is the critical voltage in kV, H is the distance between the tip of the capillary needle and the collecting mandrel in cm, L is the length of the capillary needle in cm, R is the radius of the flow channel in cm, and [gamma] is the surface tension of the fluid in dynes [cm.sup.1].
[9] studied the various in wall thickness and cross-section under various operating parameters and mandrel parameters for the NC bending of TA18 tubes and presented a method for quickly determining the range of the axial mandrel feed.
The model incorporates programmable mandrel positioning with anticipated mandrel retraction, clamping, pressure die and boost die movements.
Use sandpaper, an electric sander, or the multitool, plus a sanding mandrel and 60-grit 13mm sanding band.
Diverge tools also require finer programming of the differential angle between bushing and mandrel (should be in the 2 [degrees] to 7 [degrees] range).
In addition to increased heat losses from slag pool in melting of hollow ingots additional heat removal to the mandrel from the remelted metal occurs.
