Morara MT-ID
Morara MT-ID: the high production internal cylindrical grinding machine
The horizontal axis multi-spindle MORARA MT-ID internal cylindrical grinding machines are the ideal solution for internal grinding: it stands out for its remarkable speed of grinding with a perfect finish.
The workpiece head is fixed, (manually adjustable or with optional B1 axis), with the capacity to support overhanging weights up to 1,000 kg, with 450 Nm of nominal torque. The continuous universal torque turret (B axis) can accommodate up to four electrospindles, while the wheel holder unit is placed on a front cross carriage. The B axis (grinding wheel) allows continuous positioning from 0 ° to 270 ° with absolute repositioning precision.

Details that make the difference
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.
Grinding wheel spindles
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
Grinding Head
The optional B axis can accommodate 3-4 spindles, ensures combined grinding of internal diameters with multi-spindle performance and shaving on medium-sized pieces. It performs a remarkable internal grinding speed with a perfect finish.
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.
Discover the possible configurations
Wherever you need a precise, fast, easy-to-use machine for internal diameters, capable of dealing with very different profiles, MT-ID solves your job in a simple and effective way.
- Ideal for grinding of internal diameters and profiles, for holes and faces.
- Grinding of internal diameters and shoulders in a single piece grip: ideal for gear grinding
- It is able to perform cylindrical and conical grinding
- It allows to grind pieces in very hard material (Tungsten Carbide , etc.), thanks to the possibility of using more wheels for the same hole: roughing and finishing.
