P.D. Browne will be presenting the You Ji AH-06 CNC Turning Center at Houstex 2017. This machine was specifically designed and built to provide a direct replacement for popular heavy-duty CNC turning centers manufactured in the 1980s. While current production large CNC turning centers may lack the power and rigidity of older machines, the AH series delivers that special level of performance that often can’t be found on other modern turning centers.


You JI AH-06 Turning Center

The You Ji’s one piece 45° slant bed casting is massive. Even the shortest bed length weighs in at nearly 40,000 lb (18,000 kg). Bed lengths start at 40″ (10 mm) and go up to 160″ 4000 mm). To both enhance operator accessibility and add mass to the saddle assembly, the cross slide is at 55° angle. Widely spaced box ways in both axes, with hand scraped Turcite-B applied to mating surfaces, provide superior cutting performance and precise positioning. Large diameter precision ballscrews (2.5″ [63.5 mm] in the Z-axis) and high power FANUC servo motors deliver high axis thrust for heavy turning, boring and drilling.

The heart of any lathe is the spindle, and You Ji’s spindle is everything users need in a heavy-duty machine. Using two sets of double row roller bearings for radial loads and a pair of angular contact bearing for axis loads, this proven design delivers unsurpassed strength and precision. The spindle is housed in all-geared headstock. The three-speed geared head is equipped with an oil chiller unit to maintain thermal stability. A 60-hp FANUC motor driving the spindle through the gearbox provides exemplary torque of 3,154 ft./lbs. at just 100 rpm.

To take all of that power, the massive 12-station hydraulically actuated and clamped turret delivers. The 6.5″ (165-mm) thick turret tool disk houses 1.25″ (31.75-mm) square shank turning tools and boring bars up to 3″ (76 mm).

Other modern features include a coolant tank that is separated from the machine base to prevent heat transfer from the coolant to the machine casting. This helps to ensure precision and promotes easy cleaning and maintenance. Outstanding standard features include an extra wide high-capacity chip conveyor, programmable tailstock, oil skimmer, and the fully loaded Fanuc OiT-F control with 10.4″ (264-mm) LCD and Manual Guide i conversational programming.
