The Deckel Maho HSC 75Vlinear vertical machining centre, able to provide full 5-axis simultaneous machining cycles, has the advantage of ultra-short positioning times through the use of linear drive systems in each of its three main axes capable of accelerations of 2 G up to the ultra high speed 90 m/min rapid traverse rate.
The machine has axis travels of 885 mm in X, 600 mm in both Y and Z. This offers good productivity when carrying out 3D machining cycles involving repositioning between each pass or movement to a new feature to be produced on the component.
The machine is constructed using a heavy duty cast iron gantry that supports both X- and Y-axis movements. Carried on the gantry is a B-axis fork-head arrangement driven by torque motor that provides a -10 deg to +110 deg swing with hydraulic clamping in its programmed position.
The bi-lateral mounting of the spindle ensures high levels of mechanical stability and through absolute positioning, integrates with a 360 deg NC rotary table that has a working surface of 750 mm diameter and will hold parts weighing up to 800 kg.
