Uses & Things To Consider When Buying Acme Thread Tap
ACME
threads taps are devised to let rotary and transversing motion on machines; and
are also used in jacks, valves, presses and other mechanisms where heavy loads
are encountered. These threads are characterized by a 29° included angle. These typically
require specialized engineering and design due to the nature and severity of the
cut required in producing Acme threads.
When
making a selection of acme thread tap, consider below-mentioned pointers:
· Have a complete
acme thread tap details including size, class of fit, pitch, number of starts,
right or left hand, etc.
· Length of the
thru-holes. If an extra long nut has been specified to improve axial support,
consider counterboring a portion of the nut to the OD of the screw thread.
· Extra-long
thru-holes are difficult to tap, may require a special and more expensive tap,
and are likely to present fit-up problems.
· The direction
of tapping i.e. vertical or horizontal
· Type of tap
feed which means lead screw or manual feed
Acme
thread tap is extremely useful for the lead screw shaft of various assemblies.
In Particular, for assemblies that move efficiently either for load-bearing or
accuracy. We can see those tread taps in
the lead screw shafts in some equipment; however, most are hidden from
sight. For example, lifting pallets,
marking and labeling machines, medical diagnostics, and personal mobility, off-road
equipment, and machine tools, all require load-bearing or accurate movement
which can be provided by devices that use acme thread tap mechanism.
