MATE Precision Tooling, represented in Australia by Advanced Sheetmetal , has released a tool system designed to produce threaded holes in all types of sheet metal in thick turret punch presses.
The Mate EasyTap extends the punching capabilities of CNC punch presses by producing precisely-located threaded holes at high speed, automatically and with repeatable quality.
There is no need for secondary tapping operations either by hand or with adjacent machines. The threaded holes are produced in prepunched holes or in extruded holes located on the sheet.
The system is designed to operate in thick turret presses equipped with auto index stations, programmable ram depth capability, and suitable software. The thread tapping operation is accomplished automatically through a coordinated rotation of the turret press auto index station and the ram stroke. The tooling will produce a full range of threaded hole diameters in most materials including stainless steel, mild steel, and aluminum.
It is fast to set up and install. It uses standard taps and Bilz collets to produce the threaded holes. A push button length adjustment feature sets the tap length.
Additional features include an automatic lubrication system that dispenses a preset amount of lubrication to the tap point with each tapping cycle and a built-in lubrication level sight gauge. Prepierce hole miss protection prevents tool and part damage in the absence of a prepierced hole. A lower tool assembly with integral ball bearings prevents under-sheet marking. Guides made from hardened tool steel give accurate, long-life operation. The system is supplied with a table-top setup and storage stand to protect tooling and make setup easy.
