Quicktech T8-M / T6-M

The Quicktech T8-M / T6-M is a compact single-spindle turret lathe with C axis: a 45° slant bed, 400 mm (15.7 in) of swing over the bed and a BMT-55 power turret with 12 stations. The maker prints two spindle sizes in one column, so bar capacity reads 65 mm / 42 mm (2.6 in / 1.7 in) and the spindle bore 66 mm / 43 mm (2.6 in / 1.7 in).

M stands for the milling version. Its table has the C-axis rows that the plain turning column lacks, with a least command unit of 0.001° and a positioning accuracy of 0.02°, and Quicktech's text says that with available live tooling and C-axis capability, milling and turning can be completed in one machine. Cross-holes, flats and face drilling patterns are the work this adds. Without a Y axis, flats are cut by interpolating C and X, which is fine for wrench flats and less so for wide, accurate keyways.

The envelope is that of a chucker. Maximum turning diameter is 200 mm (7.9 in), swing over the cross slide 230 mm (9.1 in) and maximum turning length 100 mm (3.9 in), on X1/Z1 travel of 200 mm / 320 mm (7.9 in / 12.6 in). Short Z keeps the machine short as well: 2,450 mm without the chip conveyor.

The motor row gives a servo spindle of 11 kW (14.8 hp) for the larger size and 7.5 kW (10.1 hp) for the smaller, with 11 kW (14.8 hp) optional there. Speeds in the maker's feature list are 3,000 rpm (4,000 rpm) / 4,000 rpm (6,000 rpm). Axes run on 35 mm (1.4 in) linear guide ways with Ø32 x P10 ball screws at a rapid feed of 30 m/min (1,181 ipm). A Mitsubishi M80 is the control.
