32mm Tapered Button Bit For Mining 11 Degree 6 Tungsten Carbide
Tips
Description:
Cemented carbide is one of the most successful composite
engineering materials produced.
Its unique combination of strength,hardness and toughness satisfies
the most demanding applications – but working with such high
stresses, inserts and buttons are more subject to wear.
MTH also use the same hot inserting technology as including the
steel materials and Heat treatment.
Button bits should be reground when penetrati on rat es drop or if
the cemented carbide shows signs of damage
Fixed grinding routines often result in good working practices.
Bits for instance, can be examined and then reground after a
specific number of holes, or at the end of the shift. Premature
grinding is not necessarily uneconomical since less carbide needs
to be ground off. It is better to regrind rather than reducing
productivity due to damage.
Correct grinding adds considerably to drill bit service life. But
equally important, it also enhances the performance of the entire
drilling operation, especially hole straightness.
