Hartford TGV Series

he TGV Series stems from Hartford’s great experience in the production of portal machining centers.

This is a product range designed for the production of large molds and difficult to cut materials.

The complete range is made in 2 models in various versions, to cover the different application needs and from time to time customized according to the customer’s needs.

The monolithic base made of stabilized Meehanite cast iron, with a reticular structure that allows the dissipation of heat and damping of vibrations, is equipped with n. 2 linear guides with a degree of precision SP widely dimensioned, have characteristics of high rigidity, low sliding friction and silent operation.

The large dimensions of the guides on the base guarantee uniform weight distribution, absolute immobility of the workpiece, fluid movements with consequent lengthening of the life of the machine, superior cutting capabilities and absolute precision in machining.

The portal / crossbar, made of Meehanite cast iron, is a structural element to which particularly advanced (patented) technological solutions have been dedicated to guarantee rigidity and precision.

The crosspiece has 2 linear guides with SP precision degree, ensuring a wide support base, high stability of the spindle head and a high damping factor of the vibrations generated by the machining.

The spindle head is a monolithic structure, in special cast iron, characterized by ribs and “drains”.

The kinematics of the axes are guided by high precision ball screws in class C1, with double preloaded nut and supported by angular contact ball bearings (60 °), to maintain high standards of precision, the screws are cooled by passing of oil.
