Punch Former Dual
► Suitable for precision grinding different kinds of punches and EDM electrodes on surface grinder.
► Thanks to its vertical & horizontal movement allows oval punch forming.
► V-block needs to be adjusted to center depending on different dia. Of the workpieces in order to achieve 0.005mm accuracy.
► Standard accessory; crank for dressing grinding wheel into various cross sections of flat or curved shapes.
Main parameters:
Center height……………………………….……80 ~ 81mm
Clamping dia. range of V-block………Ø 4 ~ 30mm
Travel of V-block…………………………………………30mm
Slide plate horiztonal movement…………±12.5mm
Indexer tooth q'ty & accuracy ……… 24、15°± 10"
Clamping accuracy (50mm) …………………0.005mm
Capable wheel size of dressing……….……Ø 200mm
Max. radius dressing Convex ………….………R48mm,
Max. radius dressing Concave……......……R100mm
Calculation Formula:
Dressing convex arc .………………………… h=H-R
Dressing concave arc ………….……………. h=H+R
h: distance from tip of diamond to base of PunchFormer
H: Center height of Punch Former
R: Radius of the arc to be dress
