HORIZONTAL MACHINING CENTERS Umill 1800 is equipped with two types of numerical


controls, the Siemens 840D Solution Line or the Heidenhain TNC 640 HSCI able to manage both milling operations and turning operations. The head is available in two versions,


which differ in the type of motor: a high-speed motor TQJOEMF L8 BOE

Pratt Burnerd America/Atlas Workholding Large Power and Manual Lathe Chucks for Horizontal and Vertical Machines


rotation speed of up to 6000 rpm. The head has another unique


feature connected to the rotary axis: its shape allows positioning the tool for working in undercut up to −15°. In the horizontal position the tool axis is exactly aligned with the direction of the table movement. Other machines cannot orient it in the same way; and then to perform an operation along the Y axis they must interpolate the axes X and Y. Being able to engage a single axis, however, has accuracy advantages, thrust force benefits, and a reduction of complexity in programming.


The VTL Chuck shown in the photo above is designed with Extra Long Master Jaws, Cover Plate and Wiper


Blades to protect the Chuck’s gearing and reduce down time for maintenance.
