3000mm Milling Length Beamless Dual-Drive Dual-Power Head Milling Machine Model XB-3

3. Segmented Fully Hardened Guide Rails: (Top-of-the-line configuration) Guide rail dimensions: 40*80*600mm, material: 40CrMo, integrally quenched and tempered, high-frequency hardened to a hardness of HRC48-50, precision ground to ensure accurate segmented splicing. If the equipment has been used for an extended period, the guide rails can be removed for repair or replacement to restore accuracy and extend the equipment's lifespan; straightness not exceeding 0.40mm/3000mm.

4. Lifting Column: The column is bolted to the slide. The slide is made of high-strength cast iron (HT-250), integrally cast and then machined. The slide can move left and right on the bed guide rails, while the column can move forward and backward perpendicularly to the bed. The lifting slide screw on the column is driven by a motor and reducer to achieve electric lifting and lowering, or manual lifting. Limit switches are installed on both the upper and lower sides of the lifting column to ensure that the power head does not exceed its travel range due to operator negligence during lifting, thus preventing accidents.

5. The milling power head uses a high-quality, self-made milling head specifically designed for edge milling machines (a stable product independently designed and manufactured by the company). The milling power head is mounted on a lifting slide on the left side of the column and can be electrically raised and lowered with the column slide screw. For fine adjustments, manual adjustment is required to ensure safety and accuracy during tool setting. The worm gear shaft on the slide can be tilted at a corresponding angle to the horizontal plane, enabling machining of the front face (0-85°) and the bottom face (0--45°) end face or bevel. The milling feed speed can be adjusted at any time to meet the needs of milling at any speed and rapid return. It also features reciprocating milling functionality.

6. The power trolley features a non-standard, enlarged design and is a separately designed unit. Gears and reducers are mounted on the large slide, with the gears meshing on the guide rail rack. A low-noise, high-torque reducer with hardened parallel shaft helical gears drives the machine via a variable frequency motor. The frequency converter, through a controller, allows for stepless speed regulation of the traveling mechanism. Detailed traveling and milling speeds are displayed on the digital display on the milling machine's control panel. It is convenient, fast, and highly efficient. This machine has two independent power trolleys, which can be controlled independently or in conjunction. A safety anti-collision device is installed between the two trolleys.

7. Milling Cutter Head: The milling cutter head of this machine tool uses a high-quality domestically produced milling machine-specific milling cutter head that meets national standards. Based on the customer's machining requirements for Q345D high-strength steel plates, a Φ125-160 high-strength 75° cutter head is used to reduce the cutting contact area, lower cutting temperature, and reduce tool wear. YW series carbide high-alloy inserts can be used.
