High Production Turn-Mill Centers

The C100 series of production turn-mill centers are versatile, high production machines linked in real-time to the company’s Virtual Machine programming and simulation suite.

Virtual Machine includes user software that is a mirror of the real machine configuration. The data allow users to program, set up and operate the “virtual machine” in exactly the same way as the real machine. The “virtual machine” allows users to test programming changes without any risk and without using CNC machine time for program tryouts.

With three 14-position tool turrets and identical main and counterspindles, the machine is designed for fast production of medium-complexity turned parts from barstock ranging from 30 mm to 42 mm in diameter. Especially useful for small to medium lot sizes, the company says, the three-turret machines deliver high performance within a small floor space and is designed to handle fixed headstock work often run on Swiss-type machines.

The machine features 30-mm bar capacity with 9,000-rpm spindles. Also, 42-mm bar capacity is available with 7,000-rpm spindles. Both versions can run parts ranging to 200 mm in length. The drives are 20/29 kW and 25/29 kW for the 30-mm and 42-mm versions, respectively.

As many as three tools can work simultaneously with both Y axes and backworking at the same time. The counterspindle with a driven Z axis can be synchronized with travel of turret 3. Counterspindle pick-up from the spindle is accomplished in 1.5 seconds.

The machine is configured to complete a range of parts—from simple to complex and small to large batch sizes—so users can expect high machine usage rates, the company says. Parts can be unloaded from the main spindle or counterspindle.

Simultaneous machining with two Y axes at the main spindle or one at each the main and counterspindle are possible. Each features 70-mm travel to enable users the option to divide machining operations for optimum machining efficiency and flexibility.

The turret slides move in the X and Z directions on single-plane guideways. This permits rapids of as much as 60 m/min and accelerations as high as 1G with maximum rigidity. The plate-type guideway of the turret slides also means turrets glide directly on the machine bed, ensuring high stiffness and damping, resulting in longer tool life and better surface finish, the company says.
