High Speed Automatic Turning(2)

The Sprint 65 linear offers advantages for the bar machining of workpiece diameters up to 65 mm as well as for chuck workpiece diameters up to 175 mm, the company says. The machines are designed with linear drives in the X3 axis, Y axis in the standard version, a 55-degree slanted bed and three 12x revolvers. In the manufacturing process, the simultaneous use of up to three tools leads to high productivity for non-stop operations, both for complex or simple turning workpieces, according to the company.

The Sprint 65 linear offers advantages for the bar machining of workpiece diameters up to 65 mm as well as for chuck workpiece diameters up to 175 mm, the company says. The machines are designed with linear drives in the X3 axis, Y axis in the standard version, a 55-degree slanted bed and three 12x revolvers. In the manufacturing process, the simultaneous use of up to three tools leads to high productivity for non-stop operations, both for complex or simple turning workpieces, according to the company.

With the three standard equipped revolver heads and the Y axis, this machine can perform simultaneous machining with three independent tools. The 36 driven tools on the Y and C axes allow the machining of complex workpieces.

The automatic lathe is especially useful for machining of short turning workpieces for small and medium lot sizes. The use of linear drive technology in the X3 axis contributes to this achievement. The machines of this series not only offer high dynamics with acceleration up to 1 G and rapid traverse speed up to 40 m/min, but their direct measuring systems also lead to maximum precision. An additional productivity increase is achieved by the integrated spindle motor on the main and counter spindle, each with rotational speeds of 5,000 rpm.

After finishing, the workpieces are transported out of the work area through the counter spindle. The bar feed itself doesn't impact productivity because this step in the process occurs parallel to the ejection of the workpieces. As an option, the lathe can also be equipped with an integrated gantry system, both for bar and chuck machines.
