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 than the stamping operation.
Hutchison tapping heads can cover a wide tapping range from #2-56 to 1-11/4” – 12 or metric equivalent, for multi-spindle hole patterns as well as single spindle units.
In the past year, Hutchison have consulted on 1,289 separate Drilling, Tapping and Machining projects. These projects resulted in customer savings ranging from $26 to $236,000 per project.
Single-Spindle Tapping Units
Multi-Spindle 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.
Strip-Following Tapping Units
A strip-following tapping unit can begin to thread the part as soon as the material feeds into position, allowing for a larger tapping window during the press cycle. A larger tapping window translates into lower gear ratios, and the lower the gear ratio the faster the press can run and still maintain the proper rpm on the tap. In some cases, when tapping in higher-stroke presses, production rates can double compared to conventional tapping methods.
Servo-Driven Tapping Units
Servo-driven tapping units allow the the threading operation to function independently of the press stroke. This capacity is particularly useful with large-diameter taps. Servo-driven units can tap for more than 180 degrees of the press cycle at specified rpm and rapid reverse in a shorter cycle time than conventional mechanical-driven units.
