Hebei Daheng CNC milling machine-ray machine Description: I. Introduction: the structural characteristics of the machine: fixed bed, table movement; spindle box with the slide plate at moving; can move left and right along the beam; boring and milling configuration 7.5kW master 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 three-axis machine tool by the frequency stepless speed. 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 HRB bearings grating using Yixin brand slide rail and the table used by the US polyethylene wear plastic paste. Second, the machine main technical parameters: 1. Machine main parameters: Table size (width × length) 3000 mm1250mm vertical stroke width 800 mm T-type 22 mm T-slot spacing 250mm 2. Processing range parameters: Table travel 3300 mm two column spacing 2000 mm headstock down feed 800 mm maximum working height 1000mm 3. Main Head parameters: Spindle motor power (S1 / S6-60%) 7.5kW spindle speed range 10 ~ 800 r / min infinitely variable spindle output torque (S1 / S6-60%) 700 Nm spindle taper ISO No.50 (BT50) 4. side milling spindle power (S1 / S6-60%) 7.5kW spindle speed range 50/108/180/322 manual transmission output shaft torque (S1 / S6-60%) 500 Nm spindle taper ISO No.50 (BT50) 4. Machine parameters: Machine total capacity of 30 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 inverter motor T type screw drive, drive table movement, to achieve Y-axis linear motion. Rail forms: a V-flat rails, table laminating, and using a gear pump circulating oil lubrication. 2. X-axis: milling head slide plate along the beam guide reciprocates. X-axis drive: AC inverter motor T type screw drive, slider carriage laminating. Rail forms: plastic coated sliding compound guideway. 3. Z-axis: milling head ram along vertical reciprocating slide plate rails through to the motion. Z-axis drive: AC inverter motor drive T-screw driven feed movement up and down the headstock through the turbine reducer, turbine housings with self-locking capability in the form guide: plastic coated sliding compound guideway. 4. Large: Large machines include bed, table, column ,, beams, milling apron, 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: Head rectangular pillow main structure, the main motor adopts variable frequency AC spindle motor Shanghai Tomita, power 7.5kW, spindle speed 10 ~ 1000r / min, helical gear boxes through a high torque increase torque and then through inverter . This milling head is the company's own, with wide speed high torque cutting power, easy to shift (in the process of random change without stopping the spindle speed spindle to travel through a long, rigid, according to user requirements to do more long It can be, because it is the entire headstock feed milling spindle make up the traditional gap between the sleeve into the sleeve to improve the accuracy, the turbine housing itself to use with self-locking capability, without using a conventional milling head that regulate the feed size After use the wrench locking spindle, the milling head can also manually feed speed can be infinitely variable speed automatic.
