Supply fixed beam precision CNC milling machine

 I. Introduction: the structural characteristics of the machine: fixed bed, table movement; spindle box with the next move leavened board; also move along the beam about three-axis linkage; configuration 18.5kW main boring and milling head. Machine has a milling, boring, drilling, countersinking and other functions, suitable for processing machinery, iron and steel, energy, automotive, aerospace, steel, shipbuilding and other industries large and medium-sized parts. Equipped with accessory milling workpiece can be achieved in a single setup, installation right angle milling head can be five-sided machining, a machine to improve processing quality and productivity of the workpiece. The machine is controlled by a new generation of systems of CNC 10A. To ensure the performance and reliability of the machine, the machine bed in our large number of high-quality spare parts: high-quality precision bearings NSK bearing motor with large motor screw Hua Taiwan ball screw slide rail and the table used by the US poly Ethylene wear plastic stickers. Second, the machine main technical parameters: 1. Machine main parameters: Table size (width × length) 3000 mm1000 mm vertical stroke width 800 mm T-type 22 mm T-slot pitch 160 mm 2. Processing range parameters: Table travel 3300 mm two column spacing 1450 mm headstock down feed 800 mm maximum working height 1000mm 3. Main Head parameters: Spindle motor power (S1 / S6-60%) 18.5kW Spindle speed range 10 ~ 6000 r / min spindle output torque (S1 / S6-60%) 100 Nm spindle taper ISO No.50 (BT50 ) Magazine wife Taiwan Okada disc magazine spindle Taiwan Jian Chun spindle. 4. Machine parameters: Machine total capacity of 60 KVA electrical machine weight of about 25000 Kg Overall dimensions (length × width × height) of about 8000mm × 2000mm × 3500 mm Third, the main structural features of the machine: 1. Y-axis: fixed bed table along the rail body longitudinal reciprocation. Y-axis drive: AC servo motor drive ball screw drive, drive table movement, to achieve X-axis linear motion. Rail form: Bank of Taiwan on 65 roller linear guides. 2. X-axis: milling head leavened plate along the beam guide reciprocates. X-axis drive: AC servo motor drive ball screw drive. Rail form: Bank of Taiwan on 55 roller linear guides. 3. Z-axis: milling head ram plate along leavened by rail to vertical reciprocating motion. Z-axis drive: AC inverter motor counterweight guides in the form of a ball screw driven through the inlet to the motion up and down the headstock, and add parallel bars: Taiwan silver 55 roller linear guides. 4. Large: Large machines include bed, table, column ,, beams, milling leavened plate, milling ram, milling head. Large machines are made of resin sand molding, high-strength high-quality cast iron. Large blank after heat aging roughing second tempering to eliminate stress; aging treatment sufficiently rough to eliminate processing residual stress; finishing with Free clamping manner on the CNC gantry milling machine for high-speed light cutting, so that the machine has a good rigidity and accuracy performance. 5. Main Boring Head: main milling spindle Taiwan with automatic broach, Pulley structure.
