MATE Precision Tooling, represented in Australia by Advanced Sheetmetal Technologies , has released the Mate Pilot tool calibration system. It is designed to verify and restore the angular alignment of the punching stations of a turret press.
The system provides punch press users with an effective and reliable means for maintaining top punch press performance while safeguarding tooling and eliminating scrapped parts because of turret alignment problems.
It consists of a matched set of upper and lower interlocking components which are loaded into the machine's turret upper and lower chambers. The system operates in two modes. Verification mode confirms the precise concentric and angular alignment of the punch press turret to maintain high-quality piece part production and maximum tool life. Alignment mode restores the concentric and angular alignment of each station with the same precision as the initial machine installation.
Users install the two halves of the calibration instrument into the press turret station to be aligned. They then rotate the turret to position the station to be aligned under the machine's ram. Tightening the integral adjustment handle draws the two halves of the calibration instrument together. As this engagement occurs, the interlocking design of the interface causes the loosened die holder assembly to draw precisely together into concentric and angular alignment relative to the upper bore of the turret.
During this process, three-colour indicator lights on the top of the instrument signal alignment. When the indicator shows red the system is not yet aligned. A yellow light means the system is aligned angularly and concentrically within 0.030mm and a green light means the system is aligned angularly and concentrically within 0.008 mm. This last state is recommended when punching materials 2mm in thickness or less.
Each calibration instrument is machined from a single piece of the high-quality tool steel. Upper and lower halves of the instrument are separated near the end of the production process and just prior to the installation of hardware. This ensures that the two components are a precisely matched set, eliminating any possibility of cumulative tolerances adversely affecting instrument accuracy.
Mate Pilot tool calibration sets are available for Amada thick turret and Finn Power presses in A Station 12.7mm, B Station 31.80mm, C Station 50.8mm, D Station 88.9m and E Station 12.7mm.
