The machine has been designed to do fine boring of the connecting rod used in the defence sector. The machine has four high-precision spindle units with class ultra-precision bearings which provide accuracy and rigidity to the spindles. The structures of the machine are built by heavily ribbed weldment which provides rigidity and stiffness. The machine is also equipped with high pressure through spindle coolant for achieving the best quality of components. The machine comprises two fixtures mounted on a CNC slide for fine boring the connecting rod.
Generally, con rod boring can be completed in several machines. But in this machine, the parent steel bores, bush bores and pin bores are all completed in one machine with three setups. This machine can produce fine bores having taper, cylindricity and ovality of less than 5 microns with very fine surface quality as specified by the customer.
