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 forms: a V a flat, quenching grinding, laminating table, and using a gear pump circulating oil lubrication. 2. X-axis: milling head slide plate along the beam guide reciprocates. X-axis drive: AC servo motor drive ball screw drive, slide the plastic pallet stickers. Rail forms: plastic coated composite sliding rails. 3. Z-axis: milling head ram apron along the rail through to vertical reciprocating motion. Z-axis drive: AC inverter motor with ball screw driven through the inlet to the movement up and down the headstock, plus parallel bars and heavy rail forms: plastic coated composite sliding rails. 4. Large: The machine includes a large bed, table, column ,, beams, milling apron, ram milling, milling head. Large machines are used resin sand molding, high-strength high-quality cast iron. Large rough treatment by thermal aging roughing second tempering to eliminate stress; aging treatment sufficiently rough to eliminate processing residual stress; finishing the way free-clamping on CNC gantry milling machine for high-speed light cutting, so that the machine has good rigidity and precision of retention. 5. Main Boring Head: Head rectangular pillow main structure, the main spindle motor with Beijing super-synchronous servo motor, power is 7.5kW, spindle speed 10 ~ 1000r / min, enhanced by the high torque and torque helical gear boxes through Frequency . This is boring and milling head of the company's own research, with wide speed high torque, cutting power, easy to shift (in the process of random change without stopping the spindle speed spindle to travel by long, rigid, according to user requirements to do more length can be, because it is the entire headstock make up the traditional feed milling spindle sleeve into the sleeve gap to improve the accuracy by using the belt to brake servo motor with self-locking capability 6. Lubrication system: lubrication system Head into the gear box lubrication, rails and boxes screw lubrication centralized lubrication pump station and host of three parts. Head gear box, using separate box lubrication, three months for once. beamed centralized lubrication pump oil lubrication of lubrication points (such as guides, ball screws, bearings, etc.) for lubrication, and fueling the cycle can be adjusted to achieve the best lubrication, and through the electrical system control, automatic centralized lubrication. Bed automatic gear oil circulation pump to ensure the long-term in Youpao inside rail to prevent wear 7. machine safety guards: (1) using the standard "GB15760-2004 metal-cutting machine tools, security general technical conditions" (2) machine tools. The X, Y, Z-axis drive system, electric soft limit are set back to zero and the mechanical limit number of safety control devices, keep the machine in safe working condition, to ensure the absolute safety of operating personnel working (3) bed and carriage using stainless iron shield of protection (4) configuration work lights, two level indicator, machine tools, electrical parts: 1. Control the power supply unit: (1) Power supply: Three-phase AC 380V, the voltage range 360V ~ 430V; 50HZ ± 2% if the power supply fluctuations, and recommends that users configure automatic AC voltage regulator device (2) Ambient temperature: 5 ℃ ~ 45 ℃ (3) Relative humidity: ≤.. 80% of the ambient air: in a higher concentration of conductive dust, dirt, cutting oils, organic solvents, such as environment, machine control panel needs in a clean room thermostat 2. electrical configuration: feeding motor using Mandarin , spindle Beijing super-synchronous spindle motor systems: Taiwan's new generation 10A three, the precision of the machine and test methods: Standard: JB / T10051-1999 "metal cutting machine hydraulic systems General technical conditions" GB5226.1-2002 "Safety of machinery, machinery and electrical equipment Part General technical conditions" GB15760-2004 "metal-cutting machine tools, security general technical conditions" GB / T19362.1-2003 "Test conditions for CNC milling machine accuracy test" four foundations: supply-side Machine basic layout, foundation design and construction by the demand side is responsible for five randomly standard accessories: 1. Lifting lugs 2. A full columns and beams from the hanger 2 3.
