Heavy duty boring machine for boring and milling large work pieces on floor platforms. The floor boring and milling machine has no movable table, and the work piece is fixed on the landing platform, which is suitable for processing work pieces with large size and weight. The headstock moves vertically on the column, and the column moves vertically or horizontally on the bed. The headstock has a ram that can be extended and contracted together with the milling shaft. The cross-sectional shape is rectangular, square and polygonal, and is mostly rectangular. The ram has a large size and high rigidity. The ram supports the spindle and the mounting accessories. Floor boring and milling machine is suitable for powerful milling, which can expand the process range and improve the machining accuracy. The boring shaft is mounted in the milling shaft and can be separately extended and fed.
Feature:
1. Heavy duty boring machine in addition to the automatic feed, the square ram and the milling shaft also have a manual feed function, which is convenient to use;
2. The main guide surface adopts plastic-plastic technology, which can reduce the friction during the movement process, and has the characteristics of vibration absorption performance and low-frequency vibration.
3. The floor boring and milling machine feed mechanism adopts a backlash mechanism, which has high transmission precision and display accuracy;
4. Each coordinate motion guide rail is automatically supplied by an independent intermittent pump, and each guide rail surface can be well lubricated.
5. Spindle: Constant temperature cooling is adopted to reduce the heat generation of the bearing to ensure the precision of the spindle.
6. Guide rail: The guide rails of the machine X, Y, Z linear motion moving coordinate adopts the composite guide rail combined with the plastic guide rail and the rolling guide rail, and the pressure of the rolling guide rail can be adjusted steplessly according to the need, X, Y, Z III The guide rails are all operated without gaps; the composite guide rail has the characteristics of small friction, good vibration absorption, low frequency vibration, high precision, and stable motion;
7. The important part of the floor boring and milling machine is the milling head, which adopts linear guide rail, zinc alloy wear-resistant material, no noise transmission, high speed, high torque and no oil leakage.
8. Lubrication of the heavy duty boring machine: The gears in the headstock are lubricated with constant temperature oil injection. Each cutter box is lubricated by oil immersion and splashing oil. The X, Y and Z guide rails are lubricated by electric intermittent pump.
