Takamaz J-WAVE PLUS

The Takamaz J-WAVE PLUS is a gang-tool lathe for very small parts: its loading limits are a 30 mm diameter, a 50 mm length and 0.3 kg, and it holds them in a 4 in collet on a spindle that runs to 4,500 rpm with a 5.5 / 3.7 kW rating. Parts reach the spindle through a special front loading system, and the whole machine stands on 1,506 × 1,250 mm (W × L).

There is no indexing turret. The tools sit side by side on a gang slide, and the strokes reflect that: X is the longer axis at 200 mm (7.9 in), against 250 mm (9.8 in) of Z, because X is the axis that carries the next tool to the work. Both axes rapid at 18 m/min. On a part that is cut in a few seconds, a short slide move in place of a turret index is a real share of the cycle saved, and over a shift of small bushings, pins or fittings that adds up to more parts.

The 30 mm, 50 mm and 0.3 kg limits are the figures to check first. A part that is larger or heavier than that is outside what the loading system is listed for, and belongs on one of Takamaz's chucking machines. Inside those limits the 5.5 / 3.7 kW rating is matched to the size of cut such a part takes, and the Ø65 mm spindle bearing reflects the same small scale.

The XG-4 shares this frame: the same 200 mm X and 250 mm Z strokes, the same gang layout and the same 1,506 × 1,250 mm footprint, but with a built-in motor spindle that runs to 8,000 rpm. The J-WAVE PLUS, at 4,500 rpm, is the choice when the parts are near the top of the 30 mm range or in materials where the lower speed already gives the right cutting speed.
