Morara Multimatic: internal/external grinding machine

Morara Multimatic: internal / external grinding machine

The Multimatic is an internal-external multitasking grinding machine with two cross carriage wheelheads and optional turret (can accommodate 3-4 spindles).
It ensures the combined grinding of internal and external diameters and the smoothing of medium-sized pieces.
It performs several overhanging machining at the same time with remarkable speed, simultaneously grinding internal and external with a perfect finish.

Details that make the difference

Basamento Morara Multimatic

Cast iron machine bed

Stabilised and ribbed cast iron base, with peripheral coolant circulation channels. The machine model is designed using advanced 3D parametric modelling and FEM analysis techniques.

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 sparking out durante plunge and reciprocating cycles. The developped man-machine interface uses a few simple pages with a graphic support. The operator is able to set up the operations to be performed to set up through wizards for the esecution of all available machining operations.

Testa porta mola esterni Morara Multimatic

External wheelhead

Electrospindle with integrated motor on high precision bearings, designed for dynamic balancing of the wheel. Optional hydrodynamic spindle.

Elettromandrino porta mola da interni

Electrospindles for internal grinding wheels

Electrospindles of the latest generation with constantly controlled temperature and effort: our spindles are equipped with high precision bearings for conventional grinding wheels or high precision ceramic hybrid bearings for CBN grinding wheels

Morara automazione caricatore robot

Preset for automation
The Multimatic range of grinding machines has been specifically designed to be easily interfaced with different types of automation: robots, gantries, integrated loaders, post-process measuring stations. The machine is therefore equipped with a shank for automatic compensation of grinding wheel wear and automatic positioning of the coolant nozzles.

Discover the possible workings

The Multimatic grinding machine was created to satisfy the most diverse grinding needs, from medium-high production batches.

It is able to grind external and internal diameters, shoulders, conical and spherical surfaces, as well as polygons and eccentric details.
