Tongtai DC 45 Vertical machining center

Tongtai  This is a technical document about the DC-45 Vertical Machining Center for high speed contouring. It is a machine that can be used for high-speed contouring with high accuracy. It has a wide fixed working area on the table of 750x450 mm, with a maximum table load of 400 kg. The machine has a symmetric and compact double column structure, with a high rigidity gantry type structure, stroke, and X/Y/Z axis of 650/450/350 mm. The machine is equipped with various spindles, including a direct-drive type 12,000 rpm high torque spindle, and optional direct-drive type 15,000 rpm and built-in type 20,000 rpm high-speed spindles. The machine has a high accuracy feeding system, and X/Y/Z axis is standard equipped with high rigidity linear guide way preloaded high accuracy ballscrews to provide long-term machining accuracy. The machine also has a magazine door fixed on the magazine that opens while the tool magazine is indexing, which saves time for door opening and tool changing. It has a wider contact surface between the column and machine bed that makes the center of gravity of the spindle lays within the range of the column to increase machining precision of Y/Z plane. The machining samples shown in the document include plastic injection mold, with the material of NAK80, size of 200 X 130 X 50 mm, tool of R2 ball tool, spindle speed of 12,000 rpm, cutting feed rate of 1,800 mm/min, and machining time of 3 h 43 min.
