Haas UMC-750SS

What the maker publishes about the current Haas UMC-750SS

Haas makes the UMC-750SS, a Super Speed universal machining center in its UMC Series with five axes and a 40-taper spindle; the series is presented for 3+2 and simultaneous 5-axis machining. Linear travels are 30.00 in in X and 20.00 in in both Y and Z, and the spindle nose comes within 4.0 in of the platter and rises to 24.0 in. Parts sit on a high-speed dual-axis trunnion whose 19.70 in platter has seven standard T-slots and carries 660 lb. The B axis tilts through +120 and minus 35 degrees at up to 170 degrees per second, and the C axis turns a full 360 degrees at 179 degrees per second; maximum part swing is 27.0 in. The inline direct-drive spindle runs to 12000 rpm at 30.0 hp. A high-speed side-mount changer holds 30+1 tools and averages 1.80 s tool to tool. Rapids reach 1200 ipm, and cutting feed is 833 ipm. A wireless probing system and rotary scales come standard, and coolant capacity is 55 gal.

What the Haas UMC-750SS is used for

Haas puts the UMC-750SS on 3+2 and full 5-axis milling, its trunnion tilting from +120 to -35 degrees and turning a full circle so larger parts still clear the tool.

What to check on a Haas UMC-750SS

• Spindle. The manufacturer gives a spindle speed of 12000 rpm. Run the spindle to top speed and listen for bearing noise.
• Spindle load. The manufacturer gives 30.0 hp of spindle power and 90.0 ft-lbf @ 2000 rpm of spindle torque. Take a heavy cut and watch the load meter.
• Spindle taper. The manufacturer gives a spindle taper of CT40, BT40, HSK-A63. Check it for fretting and that the drawbar holds a tool.
• Axes and way covers. The manufacturer gives X 30.00 in, Y 20.00 in and Z 20.00 in of travel. Run each axis end to end and check the way covers.
• Rapids and ballscrews. The manufacturer gives a rapid traverse of 1200 ipm (the page prints the same 1200 ipm for Y and Z). Measure the backlash on each axis.
• Tool changer. The manufacturer gives the tool capacity as 30+1 (side-mount tool changer (SMTC)). Cycle every pocket and watch for a hesitation.
• Tool-change time. The manufacturer gives a tool-to-tool time of 1.80 s (average). Time a tool change against that.
• Table. The manufacturer gives a table size of 19.70 in (trunnion platter diameter) and a table load of 660 lb. Check the table and its T-slots for damage.
• Rotary axes. The manufacturer gives 5 Axis axes, B Axis - Tilt: Travel 120 ° to 35- ° and C Axis - Rotation: Travel 360 °. Run each rotary axis through its range.
