Industrial Horizontal Deep Hole Drilling Machine for Large Shafts CNC Precision Model

Industrial Horizontal Deep Hole Drilling Machine For Large Shafts CNC Precision Model – Bed Body

The bed body of the Industrial Horizontal Deep Hole Drilling Machine For Large Shafts CNC Precision Model is cast using resin sand and undergoes normalizing treatment after casting. This Industrial Horizontal Deep Hole Drilling Machine For Large Shafts CNC Precision Model adopts a split structure, assembled with high-strength bolts and positioned by taper pins. The bed features double rectangular sliding guide rails with precision grinding and high surface hardness through quenching. An oblique rack is installed on the bed for tool feed transmission; the rack is precision machined and quenched. The Industrial Horizontal Deep Hole Drilling Machine For Large Shafts CNC Precision Model offers large load capacity, sufficient rigidity, and stable transmission. V-shaped oblique ribs are arranged inside the bed body, providing high support strength and resistance to deformation. The outer wall directly supports the guide rails, enabling it to withstand large cutting forces. The guide rail rigidity is excellent, minimizing deformation and vibration during processing, which contributes to improved machining quality and efficiency. An oil return groove is cast around the bed body with an oil shield installed on it, allowing cutting oil to automatically return to the cooling oil tank.
2. Headstock
The headstock of the Industrial Horizontal Deep Hole Drilling Machine For Large Shafts CNC Precision Model drives the workpiece to rotate and is fixed at the left end of the bed body. It offers manual 3-speed and stepless speed regulation within the gear range, using a servo spindle motor to drive the spindle through belt and gearbox transmission. A manual three-jaw chuck is assembled at the front end of the headstock for clamping workpieces. Gears are precision ground, and gear tooth surfaces are high-frequency quenched to achieve high strength, high hardness, high wear resistance, and a high fatigue limit, enabling them to withstand relatively large alternating and impact loads. An external lubricating oil tank provides circulating lubrication for gears and bearings, equipped with a low liquid level alarm device. A button board is installed on the headstock box with functions including spindle jog, feed forward, feed backward, and emergency stop. The Industrial Horizontal Deep Hole Drilling Machine For Large Shafts CNC Precision Model ensures reliable headstock performance for large shaft machining.
 

3. Oil Pressure Head
The oil pressure head of the Industrial Horizontal Deep Hole Drilling Machine For Large Shafts CNC Precision Model is used for tool guiding, tool oil supply, and tool arbor support. A servo motor drives its axial movement, making this Industrial Horizontal Deep Hole Drilling Machine For Large Shafts CNC Precision Model suitable for processing workpieces of different lengths as well as tightening and loosening workpieces. The servo motor can operate in torque mode or position mode. The rotary bearing is installed in the inner body of the oil pressure head, providing good rigidity and high rotary accuracy. A rotary seal is installed on the outside of the right end of the oil pressure head body for convenient maintenance. The right end is equipped with a cutter arbor support sleeve for supporting the cutter arbor. The left end is equipped with a guide sleeve, cone disk, and oil retaining device. The cone disk positions the workpiece, while the guide sleeve guides the tool. The oil retaining device features a push-pull structure with an oil receiving box installed at its lower part to return cutting oil to the oil tank. The Industrial Horizontal Deep Hole Drilling Machine For Large Shafts CNC Precision Model integrates precision tool guidance with efficient oil supply.
4. Drill Box
The drill box of the Industrial Horizontal Deep Hole Drilling Machine For Large Shafts CNC Precision Model drives the tool to rotate and is installed on the feed support plate. It offers manual 3-speed and stepless speed regulation within the gear range, using a servo spindle motor to drive the spindle through belt, pulley, and gear train transmission. The left end of the spindle is equipped with a tool shank connecting sleeve for clamping the tool, while the right end is equipped with a chip removal bucket for discharging chips. Gears are precision ground, and gear tooth surfaces are high-frequency quenched to achieve high strength, high hardness, high wear resistance, and a high fatigue limit, enabling them to withstand relatively large alternating and impact loads. An external lubricating oil tank provides circulating lubrication for gears and bearings, equipped with a low liquid level alarm device. The drill box of the Industrial Horizontal Deep Hole Drilling Machine For Large Shafts CNC Precision Model delivers stable and powerful tool rotation.
5. Drill Bar Support
The drill bar support of the Industrial Horizontal Deep Hole Drilling Machine For Large Shafts CNC Precision Model is used for supporting the drill bar. It adopts a high-rigidity integral structure with a support sleeve assembled on it, which can absorb impact and vibration generated during processing. An automatic pull mechanism is installed so that the feed plate can automatically pull the arbor bracket back to the initial position when retracting the tool. This Industrial Horizontal Deep Hole Drilling Machine For Large Shafts CNC Precision Model benefits from enhanced drill bar stability and machining accuracy.

6. Workpiece Clamping

The manual three-jaw chuck on the headstock clamps one end of the workpiece, while the oiler cone automatically presses the other end.

7. Machine Tool Control System

The control system is based on PLC. The Z-axis performs longitudinal feed motion of the drill pipe box, with a servo motor driving the rack and double pinion mechanism through a deceleration mechanism. The X-axis controls the oil feeder servo pressing the workpiece, with a servo motor driving the rack and double pinion mechanism through a deceleration mechanism.

8. Cooling System

The cooling system mainly consists of a cooling pump, chip box, and oil tank, providing sufficient cutting oil for deep hole processing. The above-ground fuel tank is fully welded with high-quality steel plate. A telescopic protective cover is installed between the chip boxes on the fuel tank to prevent sundries from falling into the tank. Pressure, liquid level, oil temperature, and flow rate of the cutting oil can be displayed digitally on the control station.

9. Basic Parts and Structural Materials

Basic parts such as the box body, bed body, and supporting plate are precision cast with high-quality cast iron. After casting, they are aged twice to eliminate internal stress, stabilize structure and size, and improve mechanical properties.
10. Additional Components

The machine tool also includes a sliding guide rail, pinion and rack, electric box, and workpiece bracket, all designed to ensure reliable and efficient machining operations.
