The SPRINT 20 | 5 is designed for the serial production of workpieces of simple to medium complexity machined from the bar. The bar capacity of the main spindle is 0 20 mm / 0.8". The counter spindle can be optionally equipped for shaft unloading of workpieces measuring 0 20 x 600 mm / 0.8 x 23.6". "Another feature that promotes both reliability and precision is the stable construction of the SPRINT 2015," said a company spokesperson. "Robust 25 mm / 1.0 inch widely spaced ball guides ensure consistent rigidity. The thermally stable cast base is designed as a flat bed, and steep covers in the interior allow optimum chip flow. It also has up to 23 tools, including up to six driven tools that can achieve chip-to-chip times of less than 0.2 seconds thus ensuring maximum efficiency. This high level of productivity is further enhanced by solutions for automatic workpiece unloading."
The main spindle is also equipped with a C-axis for the machining of complex operations. The counter spindle is equipped with a C-axis when combined with the optional driven tools for rear-sided machining. Both drive spindles are designed as integrated spindle motors. The main spindle has a rating of 2.2 kW / 2.9 HP and 14 Nm / 10.3 ftlbs. With speeds of up to 10,000 RPM. A maximum 1.5 kW / 2.0 HP, 4.8 Nm / 3.5 ft-lbs. And 10,000 RPM are available on the counter spindle.
"In combination with our SWISSTYPEkit the stroke of the main spindle is extended from 60 to 180 mm / 2.4 to 7.1 inches, allowing both short and long turning on a single machine," said Paolo Musante, Managing Director of GILDEMEISTER Italiana S.p.A. "Mounting the guide bushing and changing the control via menu navigation is all it takes. The entire process takes less than 30 minutes. This simple and speedy conversion from short to long turning offers our customers two decisive benefits. Firstly, they only need one machine for two different workpiece varieties. Secondly, they reduce their variable costs. Short workpieces can, of course, be machined on a Swiss-type turning machine, but the residual length in the long turning configuration here is 170 mm / 6.7 inches in h9 quality and only 70 mm / 2.8 inches in h11 quality in the short turning configuration."
In total, the work area has space for 23 tools arranged on two independent tool carriers, allowing parallel machining on the main and counter spindle. The main spindle has six pockets for front machining and six for radial turning operations. An additional four radial stations are also equipped for driven tools. There are three pockets on the first tool carrier for rear-sided machining on the counter spindle, with an additional four pockets on the second carrier. The carrier can also be optionally equipped for two driven tools including a C-axis for the counter spindle. The machine is equipped in the production-optimized STEALTH design to provide minimal space requirements.
The machine requires a space of 1.98 m2 / 21.3 sq. ft. Including the 10.4" control panel for the MITSUBISHI M70 control (FANUC 32i-B optional). "Machining workpieces with a length of 180 mm / 7.1 inches with 23 tools is certainly a market standard, and 600 mm / 23.6 inches long shafts are something special, but absolutely unique is the space requirement of less than 2 m2 / 22 sq. ft.," said Musante.
"A wide choice of options is available for serial production," said the spokesperson. "There is also a bar machining package with a chip conveyor and bar loader. In addition, the tool stations can be equipped with a quick toolchange system enabling 20% shorter tooling or re-tooling times." A highpressure coolant supply is optional up to 120 bar / 1,740.5 PSI.
The SPRINT 20|5 is suitable for machining in the medical, automotive and electronics sectors as well as fluid and hydraulic industries. Other special equipment is also available, depending on customer requirements, such as a patented unit for external thread whirling with a direct drive or a high-frequency unit with speeds of up to 80,000 RPM for milling Torx profiles in bolt heads, drilling micro-holes or whirling internal threads.
