INTERNAL GRINDING MACHINES

MTI - INTERNAL GRINDING MACHINES

Grinding machines for internal diameter of bearings, holes, rolling tracks

The grinding machines MTI are projected to develop operations of internal grinding diameters to various types of bearings.

Features

GRINDING WHEEL and WORK HEAD SLIDES
The grinding wheel and work head slides are built with cast iron casters, sliding on V-shaped linear guides and high precision roller cages, controlled by recirculating ball screws and brushless motors. Optionally, double position control can also be performed via optical linear scales.
WORKPIECE SPINDLE
The workpiece spindle is mounted on pre-loaded high precision oblique bearings. The rotation takes place by a torque motor, directly applied inside the spindle, with liquid cooling.
DIAMOND DRESSING GROUP
The dressing of the grinding wheel can be performed in different ways: by a diamond roller ‘full profile’ or by interpolating a of cross slides axes, with diamond roller disk, single point dresser or rotating arc, depending on the machine configuration required from the customer.
GRINDING SPINDLES
The internal grinding machines MTI are equipped with a wide range of electro-spindles, with the possibility of setting the constant cutting speed and automatic wheel balancing systems with acoustic emission device.
LOADING:
The loading of the rings is performed by automatic loading-unloading system or by an anthropomorphic robot arm.
LOCKING RINGS IN WORKING
The internal grinding machines MTI can be supplied with fixing systems of the rings in working through magnetism and sliding blocks (microcentric), with roller systems and pneumatic presser or with membrane clamps, according to the type of ring to grind.
