Five machines were displayed by Takisawa Taiwan at EMO 2017, representing the company’s extensive portfolio of slant bed horizontal lathes/turning centers, including the new MX-800 twin-spindle twin-turret turning center, plus two machines from the LA range and one from the FX series.
The new MX-800 twin-spindle twin-turret turning center is constructed on a horizontal box-type base to minimise thermal deviation, thus ensuring machining accuracy, as well as increasing the distance of the X, Y and Z axes’ linear guideways to guarantee stability. The linear guideways also permit high-speed cycles to further boost productivity.
With twin facing T15 turrets and twin spindles, plus C axis for simultaneous second operation processes, the MX-800 will be ideal for multi-tasking operations in a single set-up.
The machine has twin 65mm bar capacity spindles and a maximum turning diameter, distance between centers and a turning length of 230, 1 100 and 250 mm, respectively. It can be supplied with a built-in robot or gantry, for integration into an automated system.
The FX800 CNC lathe is another true multi-tasking machine, with twin turrets and twin spindles plus C axis for simultaneous second operation processes in the same set-up. The machine has a 65mm bar capacity (52mm on the sub-spindle) and a maximum turning diameter, distance between centers and turning length of 260, 1 030 and 657mm, respectively.
With rapid traverse rates of 20m/min and a maximum spindle speed of 4 500 revs/min (5,000 revs/min on the sub-spindle), the 11kW model is billed as the ideal cost-effective turning center to suit a myriad of different workpieces.
Two turn-mill LA Series machines were also shown, including the twin-spindle LA-250YS. With Y and B axes, this has a maximum swing of 600mm, a distance between centers of
1 095mm and a maximum turning diameter and length of 370mm and 737mm, respectively. With 3 500 revs/min available at both the main (15 kW) and sub (7.5 kW) spindles, 75mm bar can be accommodated.
Also on show was the the LA-350M L16 turn-mill center designed for heavy cutting, courtesy of a spindle equipped with a high/low two-step gearbox with high torque output, plus a large spindle bore for 117mm diameter bar as standard and optionally 150mm. The T12 live servo turret with milling function is also equipped for heavy milling and drilling tasks.
The machine’s meehanite bed casting, of slant design, represents an extremely rigid structure and together with heavy-duty box-way design promotes high machining accuracies. The machine design also allows ample space for chip flow and easy clearance of debris away from the machining process.
