Six-Axis Universal Machining Center Accommodates Mold Machining

Soraluce, part of Danobatgroup, the Machine Tool division of Mondragon Corp., introduces the Soraluce TA-D 25, a six-axis universal machining center. It is available with a 49" x 49" full contouring integrated B-axis rotary table, enabling a maximum part swing of 82" with maximum load capacity of 17,600 lbs. The Soraluce TA-D 25 is part of the company’s compact product line of bed-type universal machining centers and offers travel of 98" in the X-axis, 47" in the Y-axis and 59" in the Z-axis.

The TA-D 25’s table achieves high-precision, simultaneous and continuous four-axes machining with a continuous positioning of 0.001º and rotational accuracy of ±2.5". Additional flexibility is delivered through an optional universal stepless head offering indexing increments of 0.001º in both the vertical and diagonal joints, permitting 4+2 axis machining. Its ISO 50 BIG Plus spindle is said to be capable of speeds up to 6,000 rpm and is driven by a 40-horsepower direct drive spindle motor with a built-in cooling system with 457 lbf.ft torque (S1-100%).

Alternatively, the TA-D 25 can be equipped with vertical high-speed continuous positioning heads (torque motor, C-axis) for five-axis continuous machining, or a universal automatic indexing head with electro-spindle attachment, permitting 4+2 axis continuous machining. The latter option, a flexible solution for machining molds also features a high roughing capacity and fine finishing on 4+2 axes (not continuous). The head can position the joints when the additional electro-spindle is spotted.

The TA-D 25 also features the Accura Heads technology by Soraluce, which makes it possible to compensate the head articulation positioning deviation for one particular position of the head. It enables compensation of the head’s kinematic values in specific angular head positions. Soraluce says Accura heads ensure maximum accuracy, as the measurement cycle is carried out just before the milling operation.

Further, the machining center is equipped with Soraluce’s exclusive DAS system, a smart system that monitors the machining process and, in the event that chatter arises, selects the best technological alternative to eliminate vibrations. Equipped with a user interface that makes it possible to control the evolution of the process, DAS incorporates different strategies for eliminating chatter, such as the built-in actuators located in the ram, the spindle speed turning—by automatically selecting the optimum speed—and the continuous, harmonic oscillation in the spindle speed.

The DAS system is said to guarantee optimal stock removal capabilities, achieving an increase in productivity of up to 300%. DAS also improves the quality of the surface finish of machined surfaces, extends tool life and reduces wear on internal machine components.

The work area of the machine is completely enclosed and includes roof guarding that integrates two front sliding doors and one at the back on the left, facilitating access to the work area from the front and rear for setup and measuring operations. The CNC control (Heidenhain ITNC 530 HSCI) is incorporated into in a hanging button pad arm that can be positioned to work from either the front or rear of the machine, as per customer preference, thus providing suitable control over the entire operation.
