EMCO Maier Corp.
The UMILL 1800 from MECO, part of the EMCO GROUP is a five-axis milling center in a bridge design with moving table and crossbeam permitting loading from the top or the front of the machine. It is designed for mold makers, aerospace and automotive parts suppliers, and precision engineering users and offers precision, high dynamics, operational flexibility, and cost-effectiveness.
Umill 1800 has a working range of 2,150 mm on the longitudinal axis Y, 1,800 mm on the cross X axis, and 1,250 mm in the vertical Z axis. Fourth and fifth axes are separately on the table and on the head, both with unique characteristics. It can be equipped to work as a milling machine or as a multitasking solution for milling and turning operations. The table can be dedicated to milling (and therefore with a rotation speed of 10 rpm, transmission by means of torque motor, by 1,700x1,400 mm plate and a load capacity of 10 ton) or turning (up to 250 rpm, transmission by means of torque motor, plate with 1,800 mm diameter and a load capacity of five tons. Rapid traverse is 60 m/min. The movement of the table is carried out on two guideways, size 65, with three trucks per guideway.
The maximum workable piece has a diameter equal to 2,500 mm. In case of turning operations, the spindle is locked by using a Hirth coupling/ face gears, thus disengaging the spindle and bearings from their stresses.
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 spindle (45 kW and 300 Nm in S1, HSK 100 and 12,000 rpm and beyond) and as an alternative, a 38 kW solution with mechanical transmission, tool taper ISO 50 or HSK 100, 600 Nm of torque in S1 and a rotation speed of up to 6,000 rpm.
The head is 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.
The structure of the UMILL 1800 is composed of three main parts, attached to each other, so installation time is minimized. The machine can be located on the workshop floor without having to install a foundation - and without interfering with current production.
The machine configuration supports optimal machining dynamics at any point within the working volume: the head overhang is the same regardless of the position of the axes. Without components such as rams that modify the geometric conditions, it ensures maximum repeatability and precision. The volumetric accuracy, calculated on the basis of an ideal diagonal within the working range, is among the most accurate available anywhere. Learn more at www.emco-world.com
