Heavy
Duty Vertical Tapping
Tapping
Services specialises in an extensive range of tapping operations
in adition to industrial fasteners. Shown left is one of our
Heavy Duty Vertical Tapping machines of the type used extensively
by traditional Bolt and Nut Manufacturing companies.
The
machine shown left is a Twin-Spindle machine with a capacity of
M30 up to M90 Diameter, originally built by David Etchells Ltd which
was based in Darlaston, West Midlands, UK.
Diameters greater than M90 are usually tapped horizontally because
of the weight and physical size of the components and the threading
taps. Neat cutting oil is flooded on to the cutting edges of the
taps during the tapping process. |
