The Hauser H55 is an expandable jig grinding machine, from simple bore and form grinding machine to fully automatic high-tech grinding and hard milling cell. Now with a new Hauser jig grinding/hard milling head which provides an unparalleled variety of grinding and milling strategies with its Z, C and U configuration. With its high grade rigidity and stiffness plus a significantly boosted stroke speed & frequency this has lead to the doubling of stock removal capacity, reducing grinding cycle time, whilst cutting in half spark out time. Hydrostatic guided spindle bearing system allows circular accuracies better than 0,5 µm in planetary grinding and an unparalleled U axis capacity up to +47 mm increases the grinding autonomy. Automated taper grinding is available with Z U axis interpolation. Thanks to this most modern grinding head technology, the combination of high accurate jig grinding with complementary hard milling has become a Hauser focal point. Usable surface on the H55 is 1440 x 860 mm, permissible load 800kg/optional 1500 kg.

GUIDEWAYS

Scraped sliding guideways in X and Y axis •Oil pressurized guideway- lubricating system, to avoid stick-slip effect ATC automatic tool changer ATC automatic tool changer with 12 magazine positions, permitting automatic machining with grinding wheels from Ø 3 mm to Ø 50 mm (alternatively with grinding wheels from Ø 0,3 mm to Ø 5 mm)

ATC AUTOMATIC TOOL CHANGER

ATC automatic tool changer with 12 magazine positions, permitting automatic machining with grinding wheels from Ø 3 mm to Ø 50 mm (alternatively with grinding wheels from Ø 0,3 mm to Ø 5 mm).

GRINDING MOTOR

Grinding motor 70S ATC with its extremely wide range of application, from 9000 min-1 to 70000 min-1. This grinding motor, and its state-of-the-art design, is an absolute must for getting optimal use
out of the grinding tool changer.

CONTROL SYSTEM

As standard, the X,Y, C, U, Z and W axes are CNC controlled. Based
on the FANUC 30i control with integrated PC, we have created HAUSER SOFTWARE CYCLES, ensuring that the control will perfectly cover all the special requirements of jig grinding.
