Spindle bore and bed length. The SB-28 has a 10 in (254 mm) chuck, 2.9 in (74 mm) of bar capacity, a 3.39 in (86 mm) spindle bore and 21.3 in (540 mm) of turning length, and it runs to 3,200 rpm. The SB-35 has a 12 in (305 mm) chuck, 3.5 in (90 mm) of bar capacity, a 4.13 in (105 mm) bore and 30 in (760 mm) of turning length, with a 2,500 rpm limit. Power and torque ratings are the same.
No. The SB-28 table gives X and Z travel only: 9 in (230 mm) and 23.2 in (590 mm). The SB-28Y is the Y-axis version, with ± 2 in (± 50 mm) of Y, and its turning envelope is smaller at 12 in (305 mm) of diameter and 18.5 in (470 mm) of length.
2.9 in (74 mm). The draw tube bore is 2.95 in (75 mm) and the spindle bore 3.39 in (86 mm), on an A2-8 nose with a 10 in (254 mm) chuck. For 3.5 in (90 mm) bar, look at the SB-35.
An MT5 tailstock with 19.7 in (500 mm) of travel and a hydraulic quill that strokes 4.7 in (120 mm). Distance between centres is 29.7 in (753 mm) and maximum turning length is 21.3 in (540 mm).
Three-phase power at 220 VAC and 70 A, or 440 VAC and 35 A. Compressed air at 4 scfm and 100 psi (113 L/min at 6.9 bar), never below 80 psi (5.5 bar), through a 3/8 in line and coupler.
