hss machine taps Chamfer forms, selection and application:
When cutting internal threads, all the machining is carried out by
the cutting teeth of the chamfer. Therefore, a decision on the best
type of chamfer form has to be carefully made as both tool life and
quality of thread are thereby greatly affected.
Generally speaking, the form and length of chamfer depend on the
type of hole to be tapped. The tapping of through holes does not
normally give rise to any difficulties whereas the production of
blind holes can create certain problems associated with the need to
evacuate swarf in the reverse direction to the feed, i.e. up to the
flutes of the tap and then cut off such swarf when the tap is
reversed out of the hole.
The length of chamfer is determined by taking into account various conflicting factors. To avoid overloading, premature bluntness and oversize threads the number of chamfer cutting threads must not be kept too low. A too long chamfer lead, however, increases the torque and thus the danger of breakage. The spiral point with form B ensures a chip removalalways in the direction of feed.
