CNC Horizontal Lathe JS-105

The JS-105 is a slant-bed cnc horizontal lathe built around an integrated 30-degree inclined bed base that delivers strong torsional rigidity. Its major castings are poured in HT300 resin sand and relieved through a double aging treatment, while the fixed mating surfaces between casting components are hand-scraped to lock in geometric alignment. The X/Z axis ball screws adopt a pre-stretched mounting structure that suppresses thermal elongation, keeping the 0.01 mm positioning accuracy and +/-0.003 mm repeat positioning accuracy stable across long production shifts. The upper and lower carriages use a light-weighted design that retains load capacity while allowing 24/30 m/min rapid traverse over an X travel of 160 mm and a Z travel of 400 mm. A 12-station servo turret, a 6-inch hydraulic 3-jaw chuck and a matching hollow rotary cylinder support continuous turning cycles, and the A2-5 spindle head reaches 5000 rpm on a 5.5/7.5 kW servo motor. The hydraulic programmed tailstock provides a 100 mm sleeve stroke with an MT4 inner taper, supporting long-shaft work without manual re-positioning. Both the bed body and the sheet metal enclosure are designed with an oil-water separation channel, so chips and coolant are recovered separately instead of mixing inside the machine. With a 300 mm maximum turning length and a Phi320 mm maximum disc turning diameter, the machine handles precision discs, sleeves and shafts in non-ferrous metals, castings and steel.

For shops that run the same part across a long campaign, the JS-105 is configured as a standardized, production-oriented cnc horizontal lathe rather than a customized one-off. KingKAI builds every machine through its own chain - mechanical machining, light-machine assembly, sheet metal fabrication and final assembly - under ERP traceability, which keeps lead times consistent and lets the +/-0.003 mm repeatability transfer the same first-off quality to every subsequent piece off the line.

The rigid slant bed and A2-5 spindle hold tight tolerances when turning long shafts, so runout and straightness stay inside the +/-0.003 mm repeat band.

The Phi320 mm disc capacity combined with the 6-inch hydraulic chuck supports facing, OD turning and boring in one chucking.

The 12-station servo turret indexes through roughing, finishing and boring cycles without operator change-over, keeping batch-to-batch consistency.
