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.
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.
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
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.
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.
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.
