For most stamped parts
with a tapped hole or holes, IN-DIE TAPPING has become the only competitive
alternative to secondary tapping. Secondary tapping of stamped parts has
always been far more costly then the stamping operation. The following
are some of the features of the In-die tapping heads:
Spindle and Special In-Die Tapping Units
Multiple spindle tapping units have distinct advantages over individual in-die tapping units. Parts with multiple tapped holes can often be tapped in a single station which saves die space and tooling costs. With the twist lock lead screw assembly any combination of pitch and tap diameters can be combined in a single multiple unit. The TH-55 high torque driver can tap as many as eight 5/16"- 18 holes in a single tapped part.
We specialize in custom
in-die tapping units built to customers specifications. Whether a tapped
part has three #4-40 or five 3/8"- 16 tapped holes, we will build
a top down, bottom up, or rapid advance multiple spindle in-die tapping
unit to fit your requirements while keeping costs to a minimum.
