Micro-compensation During tap reversal high axial forces are generated on the tap which cause mechanical stresses and micro-wear. This in turn leads to reduced tool life and tool precision. For this reason Vergnano synchronous tapping attachments are designed with differential mi- cro-compensation in traction and compression which compensates the stresses on the tap. Compensation in traction (1 mm) is obtained by steel springs which guarantee greater reliability while compensation in compression (0,2 mm) is obtained by elastomer rings.
Steel spring for compensation in traction (1,0 mm)
Elastomer ring for compensation in compression (0,2 mm)
Through Coolant Capability All Vergnano synchronous tapping attachments are designed for use with internal lu- brication up to 50 bars. For higher values a special pressure-tight nut screw is available on request. The special attachment design forces the through coolant to enter the tap adaptor from the sides without interfering with the compensation length.
