Mollart Chessington Secures Major Defence Contract

MOLLART CHESSINGTON IS PLEASED TO HAVE WON A MAJOR CONTRACT TO DEEP HOLE DRILL A COMPONENT FOR THE DEFENCE SECTOR, WHICH WAS FIRST MANUFACTURED OVER TWENTY-FIVE YEARS AGO! 

Utilizing our recently commissioned HD1 deep hole BTA machine, we were able to stand apart from all our competitors.

The Challenge:
  • Drill Ø97.00mm through bore X 600mm deep in an irregular profiled component.
  • Forged material, extremely challenging to procure.
  • No allowance for a second chance.
The Solution:
  • BOTEK type 42 drilling head utilizing special coated inserts.
  • In house designed and manufactured bushing technology.
  • In house designed and manufactured work holding.
