The two machines in the You Ji HBM series of table-type horizontal boring mills each feature a moving column for the Z axis and a moving table for the X axis. The design provides full support of the table over the entire X axis travel and results in maximum rigidity and accuracy, and eliminates the need for additional supports to withstand high table loads. The X axis features a unique triple box guideway with a hydrostatic way structure.
Standard X-Y-Z travels for the two machines are 79″ x 59″ x 49″ (2006 mm x 1498 mm x 1244 mm) and 98.4″ x 70.9″ x 49″ (2500 mm x 1800 mm x 1244 mm).
The machines feature precision ground and induction hardened box ways in all linear axes. All mating surfaces are hand scraped and coated with Turcite-B, and the ways are force lubricated via a pressurized automatic oil system. Large diameter, pre-tensioned ballscrews assure accurate positioning. All linear axes feature Heidenhain linear scales.
The triple-cooled 60 hp, 2,500 rpm spindle motor with 2 speed gear drive produces 1,452 lb-ft. of torque at 218 rpm.
The standard rotary B-axis has a hydrostatic bearing system and is driven via a high-precision dual pinion mechanism. With the high-resolution encoder, B-axis accuracy is +/-7.5 arc seconds with +/-5 arc seconds repeatability. Standard features includes a stand-alone heavy duty 60 tool (80 and 120 tool optional) arm type automatic tool changer, a comprehensive chip removal system, a high volume coolant system, and 300 psi coolant through the spindle. The standard Fanuc 31iM-B control features the Fanuc Alpha I servo system with 1,000,000 pulse encoders.
A comprehensive selection of options enables users to custom-tailor machine capabilities to specific production needs. Choices include axis extenders, rotary tables, pallet changers, tool and part probes and high-pressure coolant systems.
