Sugino says its selfeeder drill unit, the MS7 Mechatric, delivers an increase in the depth and diameter of drilled holes in ferrous and nonferrous metals. Featuring a 3.7-kW spindle motor and 7,800-N thrust, the unit is capable of facing and end milling operations. It is also capable of drilling 28-mm-diameter holes in steel and 32-mm holes in cast iron while achieving tight tolerances. With its 200-mm stroke and maximum cutting speed of 16.7 mm/sec, the unit is said to bring heavy-duty material removal into the company’s realm of high speed machining. Its servo-feed motor allows the selfeeder to perform a range of variable feed applications, including slow enter feeds, pecking in deep holes and reduced exit speeds to reduce burrs.
The drilling unit comes complete with the servomotor CNC, which allows programming from a console, touch panel or PC. According to the company, the unit is provides an alternative to expensive machine tools for producing high-volume work. Also, greater machine flexibility is achieved by incorporating multi-spindle heads, which maximize productivity while reducing net cost per hole. The compact 17" × 41" footprint fits into tight spaces on a production line, which allows a shop to generate more money per square foot, the company says.
