What fits a Mazak QTU-350 MY

Each of these follows from a published specification above, which is named beside it.

Workholding

A 10-inch chuck. Jaw sets, soft jaws and collet chucks for this size are commodity items, but the chuck itself, and any spare jaws, travel with the machine and are counted in an offer.

Derived from Chuck size: 10 in / 254 mm

Bar feeder fit

Bar capacity is 77 mm, so a bar feeder for this machine has to be sized for stock up to that diameter.

Derived from Bar capacity: 3.0 in / 77 mm

What to check on a Mazak QTU-350 MY

  • Control generation. The manufacturer specifies SmoothC for this model. Units we have tracked run 2017 to 2020; an early one may carry an older control or a retrofit.
  • Spindle. The manufacturer gives a spindle speed of 3500 rpm. Run the spindle to top speed and listen for bearing noise.
  • Spindle load. The manufacturer gives 20.0 hp / 15 kw (1-minute rating) of spindle power. Take a heavy cut and watch the load meter.
  • Axes and way covers. The manufacturer gives X 8.50 in / 215 mm, Y 4.00 in / 100 mm and Z 23.75 in / 605 mm of travel. Run each axis end to end and check the way covers.

  • Chuck and bar. The manufacturer gives a chuck size of 10 in / 254 mm and a bar capacity of 3.0 in / 77 mm. Check the jaws and the grip pressure; check any bar feeder is set for that bar.
  • Bed and ways. The manufacturer gives a max turning diameter of 13.500 in / 340 mm and a max turning length of 19.608 in / 497 mm. Check the ways for wear near the chuck.
  • Rotary tools. The manufacturer gives the rotary tooling as Yes - rotary tools, 4500 rpm max. Check that the rotary tools still drive under load.
