SMTCL CAK50135

CAK50135 is the longer CAK50-135 turning reference, with 1390 mm maximum part length and 1350 mm maximum cutting length in the current Chinese table. Its useful procurement question is support at the required cut: draw the grip, centre holes, tailstock and any steady/follower-rest requirement before deciding that the longer bed solves a shaft job.

The technical column retains 500 mm bed swing, 300 mm slide swing, 500 mm maximum cutting diameter, A2-8 nose, 250 mm chuck and 78 mm spindle bore. Those are separate restrictions. Include the proposed jaws, boring bar, saddle and tailstock in the collision review; a nominal diameter or through-hole entry does not establish a supported bar-feed process.

The vertical four-position toolpost accepts the listed 25 × 25 mm external tool shank reference. Rated main servo motor is 7.5 kW; the S-series dual-speed motor row is a separate configuration. Electric three-step 15–2200 rpm, manual stepless 22–1800 rpm and manual three-step/12-grade 40–1800 rpm are different drive references. Agree one transmission, its torque behaviour and control functions.

The catalogue lists a 75 mm tailstock quill with 150 mm travel, X/Z rapids 6/12 m/min, 3000 kg net mass and body dimensions 3270 × 1700 × 1735 mm. Plan long-blank loading, floor/support, coolant and chips around that body. Trial the longest supported cut using the intended tools/material, then check released straightness and diameters after the agreed warm-up. Nominal rapid speed or an IT6–IT7 entry cannot determine the accepted cycle or the finished shaft result.
