W27/W37/W50—Economical Solutions Mass Production Cylindrical Grinding

With its W series (W 27/W 37/W 50), EMAG Weiss offers the perfect machine for the economical cylindrical grinding of parts with medium and high-volume production.

With its large number of available options, this type of machine is configurable to fit a wide range of components in highly diverse manufacturing scenarios.

The centerpiece of these production CNC cylindrical grinders is the fast CNC control unit with a Sercos 3 interface. This is where the customized design of the machines comes into play with its user-oriented operator interface and software, such as DXF converter. Customization is also possible for the automation solutions (ex. gantry loader), which are entirely controlled by this unit.

The grinding headstock with a hydrodynamic plain bearing can drive grinding wheels up to 250 mm (10 in) in width and up to 750 mm (30 in) in diameter at a maximum output of 45 kW (60 hp).

The workpiece headstock comes with a standard MK4 – MK 6 spindle socket, but it can also be equipped with special sockets. The precision spindle bearing allows for radial running with a precision of 0.5 μm and a speed of 2,000 rpm. The workpiece placed between the tips can weigh up to 250 kg (551 lbs).

The tailstock, which can be operated both manually and using a foot switch, has an MK4 quill socket and a quill stroke of 45 mm (2 in).
