On a recent project for Mid-State Engineering (MSE) in Tipton, Indiana, Suhner custom ECONOmaster drill units were used to automatically drill holes into fiberglass panels for a truck trailer body. The range of hole sizes are designed for half an inch. ECONOmaster is used to reduce the center to center point of the holes drilled by a quill-feed drill.
This quill-feed drill unit is made to have selectable drill heads that can be used at once or individually. Using servo drive motors, the machine auto is meant to index down a table to ensure precision hole locations across a 60-foot span. According to Tom Raver, engineering manager at MSE, “The machine helps give our transportation customers a competitive advantage, increasing production volume while reducing rework.”
The ECONOmaster line of drilling units is made for multiple materials such as: light metal, wood, composite, plastic, and foam. Basic unit weight is 45 lbs.
This drilling unit should feature:
· low power and air consumption
· adjustable motor housing
· adjustable total stroke up to 4”
· hydraulic feed control cylinder
· J33 taper spindle end, 0-1/2” drill chuck
· electric front & rear position limit switches
· belt tensioner and chrome-plated quill.
Other key features are meant to include adjustable feed stroke of ½-3”, 400 lb. thrust at 85 psi, operating pressures to 110 psi, TEFC/IP56 protection, standard 230V/460V, concentricity of .002” TIR, speed ranges to 9600 RPM and an air connection retract/advance of ¼”-20 NPT.
Mike Ricketts, regional sales manager for the machining division at Suhner says the collaboration has allowed Suhner to offer a wide variety of products with an innovative partner that can offer turnkey systems that meet customer needs.
