Kejie JTGK-1100i

JTGK-1100i is described in the Chinese catalogue as an engraving and milling machine, and in English as a CNC machining centre. Its reviewed X/Y/Z travel is 500/1100/300 mm, with a 500 × 1100 mm table, 370 mm maximum-workpiece-height reference and 300 kg table load. Y is the longer direction: orient the drawing and fixture accordingly rather than treating the model number as X travel.

The February 2025 catalogue lists spindle power/maximum speed at 7.2 kW/24000 rpm, with BBT-30/BT30 interface reference. Obtain the offered duty/torque curve, compatible complete holders and actual configuration. Fine-feature performance also depends on cutter runout, reach, engagement and material. Published 12 m/min rapid and 10 m/min cutting feed are separate motion references, not an accepted cycle.

The catalogue lists positioning accuracy 0.008 mm/300 mm and repeatability 0.005 mm; those machine references do not guarantee the same finished electrode, mould or thin-part tolerance. An automatic tool setter and spindle cooling are listed among standard accessories, while a fourth-axis rotary table is optional. Confirm control/postprocessor and rotary scope; do not call the base build simultaneous five-axis. Graphite equipment is a separate catalogue route, so an electrode application image does not establish dry-graphite dust handling on this model.

Trial the smallest critical feature, long-Y reach and required surface using the quoted tools and CAM programme. Inspect after release, record warm-up, wear/breakage recovery and measurement method, and include manual intervention in output planning. Body dimensions are 2050 × 3010 × 2380 mm and mass 4000 kg; the catalogue power reference is three-phase AC380V ±5%, 50Hz. Reconcile destination supply and delivered access layout. The original Chinese model-page working-zone photograph illustrates access and does not certify an installed fixture.
