At IMTS on Stand 339190, Mollart Engineering is to exhibit versions of pellet die drilling spindles and close-pitch gundrilled component examples with representations of its range of deep hole drilling machines and tooling from its global partner, the German specialist Botek.
Managing director Ian Petitt said: “IMTS has always been a very successful exhibition for Mollart. Two years ago we won an order from Mexico for a 4-spindle Omnisprint gundrill for producing cast iron bottle moulds that increased drill penetration rates for the company by 500%. So successful was the process that last year they ordered a second machine.”
As the result of exhibiting at a previous show in 2014 orders exceeding $10 million were placed on Mollart by a North American automotive customer for design and building special purpose 4- and 6-spindle gundrilling machines to produce oil galleries in transmission shafts.
Mollart’s pellet die drilling expertise has supplied machinery that produce up to 200,000 individual holes in heat-treated die steel components weighing up to 2.5 tons and range in size up to 1,500mm diameter with wall thickness up to 150mm.
The proven Mollart modular deep hole drilling concept, with dedicated bespoke application engineering and when required, automation and specialist software, involves precise control of the various synchronous axes plus radial positioning of gundrill spindles that are set around a centre indexing table that supports the tubular die components. The table is also programmable for rise and fall in order to create multiple layers of close-pitched holes.
In the machine, which is a ‘lights-out’ configuration requiring minimum human intervention, all spindles work on the same row of holes to ensure high orders of efficiency and machine utilisation. Mollart has also designed and built a highly efficient coolant system to complement the production prowess of the machine.
Mollart Engineering’s expertise in deep hole drilling machines for pellet die production will be the focus on Stand 339190 at IMTS in Chicago.
