Chiron and Hurco, brands star machinery Eurotec and machinery international
The German manufacturer Chiron offers the Mill series, with major routes of displacement and high capacity of milling for the complete machining of both large and medium-sized pieces. There are six basic models Mill with tours of displacement of 800 up to 6,000 mm in the X axis.
The multifunctional 800 Mill machining center is equipped with a swivel head CN, with a CN cart with coil turning pieces as well as a package of powerful turning. It is equipped with six-axis CNC which provides a complete and highly accurate machining of six sides, even of complex parts from bar. In addition to the three axes, the 800 Mill offers a rotating head robust CN as a fourth axis CN which can be rotated horizontally with continual development in +/-100 ° through the axis x incorporates a powerful motor spindle cooling by water, thermally stable and 34 kW with speeds of up to 20,000 rpm. In this version is integrated a spindle from turning on the left side of the table of the machine. The engine, 42.5 kW of power, is tree hollow with a bore of the spindle size 65 and cooled by water and oil.
Note also the series 12 K which is remarkable for the extreme robustness of the machine and its high productivity. Chip to chip times are 1.9 s, with speeds of up to 90 m/min and acceleration of the axes of up to 2 g. In addition, the accuracy of the Centre not dependent on the weight of the piece to work, so always gets the same precision. It offers great thermal stability because all sources of heat are isolated from the structure of the machine.
They are of modular construction that can be used as mechanized (FZ 12 K) single centre or Centre for machining of two spindles (DZ 12 K). Two high performance spindles ready at the same time moving in a synchronous manner by common axes of advance manufacturing centre for machining various pieces work held in parallel at the same time. Throughout the 12 K series are designed to dry mechanization and the manufacture of parts to work with a high production of shavings. In addition, are available with rigid table and changing of parts table although they can be integrated CN circular tables of 1 or 2 spindles. Incorporates a powerful spindle with generously sized bearings and seat of HSK 50 tool that allows excellent results of milling.
In series 12 K also included innovative machining center of deep holes .tbz formats 12 W which is characterized by a high accuracy of positioning, technology of pilot drilling and optimal length of the tools for deep holes.
Hurco, the secret lies in the control
UltiMax is the programming system that controls Hurco VMX machining centres. It has touch screen interactive conversational programming to NC, automatic calculation of geometries of up 9 implicit values of coordinates, programming in parallel, automatic calculation of speed of resolutions, entry of data ergonomic, panel of control pivotable and adjustable, interactive graphical display, edited graph of programmes, cycle interruption, of progress and speed potentiometer, test cycle and wheel cursor key.
But the wide range of options doesn't end here. In addition, allows the generation of parts (d) from profiles of 2D contours, incorporates software for strategies of penetration, software for automatic planning of trajectories of automatic generation of trajectories of tool from CAD geometries with the UltiMax DXF software and tool (UtiPocket).
For its part, the machining system has a high torque and a speed of 10,000 rpm spindle. Progress has been rapid and he has a system of wide opening doors for easy loading on the table, a powerful system of washing and controller movements multi-axis based on a processor of Digital signal (DSP), which generates a precise positioning of axes of the machine to high advances. Not to mention the stiffness and extreme stability of the machine, the change of double bezo caliper measuring system by laser and the method of finite elements (FEM) that allows to visualize the structural of each of the components of the machine stabilityas well as its dynamic under the most extreme working conditions and thermal stability.
