OPTIMUM B 50 GSM UPRIGHT DRILL PRESSES

Technical Description

The OPTIMUM B 50 GSM Upright Drill Press is a heavy-duty drilling machine designed for precision and performance in metalworking applications. It features a substantial swing diameter of 31.5 inches (800 mm) and a drilling capacity in mild steel of 1.97 inches (50 mm), supported by a robust 4.02 HP (approximately 3 kW) three-phase AC motor operating at 400 V. The drill press offers a wide speed range from 54 to 2,090 RPM across 18 selectable stages, enabling versatile machining capabilities. The quill provides a stroke length of 9.06 inches (230 mm) with a feed rate adjustable between 0.00197 and 0.0118 inches per revolution (0.05 to 0.3 mm/rev), ensuring precise material removal. The machine's heavy construction includes a 7.87-inch (200 mm) diameter column for enhanced stability and vibration reduction. Its dimensions are approximately 38.8" x 30.5" x 96.85" (985 mm x 775 mm x 2460 mm), with a solid base weighing about 2,094 lbs (950 kg). A large, precision-machined drilling table measuring 23.6" x 23.6" (600 mm x 600 mm) supports workpieces up to 661 lbs (300 kg) and can rotate ±90° for flexible positioning. The spindle chuck uses a Morse Taper 4 (MT4) for compatibility with a wide range of tooling. Additional features include a maximum spindle-to-table distance of 31.5 inches (800 mm), maximum spindle-to-base distance of 51.18 inches (1300 mm), and a coolant pump motor output of 0.05 HP (40 W) for effective cooling during operation. The OPTIMUM B 50 GSM combines robust build quality with high precision, making it suitable for demanding industrial drilling tasks.
