CNC Double-Column Gantry Milling and Boring Machi | RFQ Sourcing Details

This CNC double-column gantry machining center is intended for metal-processing operations involving milling and boring. Four listed models—SKX2016, SKX2500, SKX3020 and SKX4025—provide X-axis travel of 2,200, 2,700, 3,200 and 4,200 mm respectively.

Published table lengths range from 2,000 to 4,000 mm, while rated table loads range from 6,000 to 10,000 kg. The available size range allows buyers to match the machine envelope and load capacity to their workpiece requirements. The listed spindle configuration supports BT-50, ISO-50 or CAT-50 tapers.

Standard spindle speed is stated as 3,000 rpm, with 6,000 rpm identified as an option. The continuous/30-minute spindle motor rating is listed as 18.5/22 kW, with 22/26 kW optional. Cutting feed rate is stated as 7,000 mm/min.

Rapid traverse varies by configuration: the published values are 12/12/15 m/min or 10/12/15 m/min for the X, Y and Z axes. Published accuracy data includes positioning accuracy of ±0.005 mm per 300 mm and ±0.015 mm over full travel, plus repeatability of ±0.003 mm.

The source also lists additional values of P0.03/P0.035 and 0.025/0.028 without an unambiguous model mapping, so buyers should obtain a model-specific acceptance sheet before ordering. The automatic tool changer is listed with a 32-tool capacity;24-, 40- and 60-tool configurations are identified as options.

Maximum tool dimensions are stated as 125 mm diameter with adjacent pockets occupied, 245 mm with adjacent pockets empty, 350 mm length and 20 kg weight.

Listed machine equipment includes automatic lubrication, a spindle oil cooler, spindle air blast, a manual pulse generator, working and three-color alarm lamps, an RS-232 interface, an electrical-cabinet heat exchanger, coolant equipment, twin-auger chip removal and a belt chip conveyor with cart.

Other listed or configurable items include an X-axis Heidenhain linear scale, sub-table, three-axis manual pulse generator, through-spindle coolant at 20/40/70 bar, through-tool-holder coolant interface, electrical-cabinet air conditioner, transformer, oil skimmer and oil-mist collector.

Buyers should confirm which items are standard and which require an option quotation. Procurement review should confirm the exact model, Y- and Z-axis travel, column clearance, table width, spindle taper, spindle speed, motor rating, rapid-traverse values, tool-magazine size, coolant pressure and installed accessories.

The published warranty information is inconsistent: one section states three years, while another states 12 months and excludes damage caused by people. Obtain the applicable warranty period, scope, response process and written commercial terms in the final contract.

Also request the final machine layout, foundation requirements, electrical specification, pneumatic requirements, inspection protocol, delivery schedule, installation plan, training scope and model-specific accuracy acceptance criteria.
