Deep hole drilling for mass testing of
DNA samples
Mollart Engineering's specialist deep hole drilling capability has secured a vital production contract for special perspex components to enable mass testing of DNA samples
Mollart Engineering's specialist deep hole drilling capability has secured a vital production contract in providing a single source supply, including material, for special perspex components to enable mass testing of DNA samples The production of the highly complex components, which are supplied at a rate of 120 per month by the Chessington Surrey operation, involve a 1 mm diameter hole some 75 mm deep targeted to break squarely into a cross-hole of the same diameter

Deep hole drilling takes a step forward
Mollart Machine Tools has redefined the concept and capability of deep hole drilling with the launch of the Mollart Microdrill vertical gundrilling machine.
The drilling and other machining operations must leave the material completely clear in order that the DNA sample can be viewed.
The operations also involve machining a close tolerance sealing face, which is finally lapped and polished.
The finished component is then ultrasonically cleaned by Mollart, prior to packing and shipment.
The 80 mm by 70 mm by 6 mm perspex component demanded extensive application engineering by Mollart's production engineering team using solid carbide gun drills.
Via the CNC control progressive ramp up of speed and feed is programmed on the Mollart Microsprint deep hole drilling machine.
Also involved was one of Mollart's coolant partner companies, Quaker, which helped develop the process around its Microcut soluble coolant in order to maintain the clarity of view through the material.
As part of the complete supply package, added value machining is carried out on its recently acquired Cincinnati machining centre and an additional £9,000 was invested by Mollart on equipment for the finishing operations.
