Morara MH

Morara MH

Morara MH is an external / internal cylindrical grinding machine with moving table, equipped with a wheel carriage with multiple possible configurations.

It is a machine designed for pieces of medium-large dimensions and important weights (up to 2,000 kg), and which makes versatility and absolute precision its strengths: it allows to obtain cylindricity less than 0.0035 / 1550 mm

Details that make the difference

Basamento Morara MH

Cast iron base

Stabilized and ribbed cast iron base equipped with peripheral channels for coolant circulation. This machine was designed by using advanced techniques of 3D parametric modelling and FEM analysis. Its heavy structure (around 18 tons) provides very high vibration damping.
Tacchella Proflex Testa Porta pezzo


The universal workpiece-holding head from Crossflex is perfect for surface and inter-spindle grinding with fixed and rotating spindles. Manufactured with high-precision bearings, which guarantee a roundness of less than 0.001 mm, the new workhead is on a swivelling base, with a micrometric adjustment device (0°-10°). Progressive speed variation is performed by means of a digitally-controlled AC Brushless motor, while to facilitate the movement during machine set-up, the unit is equipped with a pneumatic lightening device. A C-axis is also available as an option for machining non-round workpieces such as threads, cams, eccentrics and polygons.

The grinding wheel carriage on high precision bearings and equipped with integrated motor is it is designed for the integrated wheel balancing device. The various configurations of the wheelhead can be effectively used thanks to the freely programmable orientation of the wheel carriage (Axis B) from - 20 ° up to + 200 °
Tacchella TOP software

Software Tool Operator Package

Our interactive T.O.P. (Tool Operator Package) grinding software takes the operator step-by-step through the entire machine operation, easily and in compliance with safety regulations. The software makes it easy to manage automatic grinding cycles; roughing, semi-finishing, finishing and quenching during plunge and pendulum cycles. The developed man-machine interface uses a few simple pages with graphic support. The operator can set the operations to be performed for set-up via wizards and for the execution of all available machining operations.
