Mollart Engineering's LD4 Drillsprint deep hole drilling machine offers a 750mm stroke complete with full automatic loading and unloading along with a range of the latest deep hole drill tooling from Botek.

Said Managing Director Guy Mollart: "The North American market is important to us and as an example of our success, between March and August we have installed or taken orders for eleven machines."

These orders include two 4-spindle and two 3-spindle machines with automatic loading systems plus a stand-alone 2-spindle machine all for producing gun barrels. Four 4- spindle machines have been ordered for drilling for engine valves and a 2-spindle machine for medical components. In addition, a 2-spindle machine is on order to produce for thermowell temperature sensors and a 4-spindle machine for transmission shafts which has been tooled using the latest Botek HP gundrills.

The Drillsprint LD4 has a capacity between 2mm and 16mm diameter by 750mm deep, can be supplied with counter rotation to create concentric bores and is ideal for thin wall components. There is a range of auto loading solutions including gantry, pick and place and robotic systems. Machines can be supplied with one, two, three or four spindles.

Amongst the latest tooling on display will be the single lip, solid carbide Botek gundrill, the Type 113-HP, which has a penetration rate up to 800 per cent faster than conventional drills for use in special gundrilling machines, machining centers and lathes that have through-tool coolant supply. Tools are available between 0.7mm and 12mm diameter with a depth to diameter ratio of up to 80:1.
