with our wet-grinding machine
2) Before mass production of SDS hammer carbide tips, we need to do a trial pressing and sintering, and we check the
appearances and the sizes of the samples with micrometer to ensure
that the requirements of the drawings can be met before batch
production
3) Bulk production ,press the raw materials to shape blanks,and SDS
hammer carbide tips must be passed by semi finished inspection.
4) sinter blanks to finish (HIP) and finished products inspection
to ensure the best quality and production capacity.
