Brother SPEEDIO S700X1N

The Brother SPEEDIO S700X1N is the long-stroke model of the X1N vertical line: 700 mm (27.6 in) of X travel over 400 mm (15.7 in) of Y and 305 mm (12.0 in) of Z, a BT30 spindle running 10,000 rpm as standard, and a turret magazine with 14 or 21 positions.

That X stroke is the reason to pick this model. Seven hundred millimetres lets you line up several vises or a string of fixtures along the table and run them in one cycle, or machine long narrow parts such as covers, rails and manifolds without a second setup. Y and Z do not grow with it, so the machine gains length only, not depth or height.

Spindle choice deserves attention when a used or new machine is specified. The standard spindle tops out at 10,000 rpm and a 16,000 rpm spindle is listed as an option. For small end mills in aluminium the faster spindle is the one to ask for; for drilling, tapping and general milling in steel and cast iron the standard one does the job. The table gives a single power rating, 5.5 kW (7.4 hp), which rules out heavy roughing whichever spindle is fitted. BIG-PLUS holders are optional on the BT30 taper.

Axis speeds are 50 m/min (1,969 ipm) on X and Y and 48 m/min (1,890 ipm) on Z, with a chip-to-chip time of 1.4 seconds. A separate axis-speed row on the same table reads 50 × 50 × 56 m/min, which contradicts the Z figure, so treat Z rapid as unconfirmed until Brother states it for the machine in question.

Table load is 200 kg (441 lb), and on a long-X machine that limit covers everything spread along the table at once. A row of steel vises with blanks in them adds up quickly. The control is Brother's CNC-C00 and the supply is 200/220 V three-phase.
