3. Description of workpiece processing process
(1) Place the workpiece onto the dedicated workpiece holder.
(2) The pneumatic system controls the guide frame to press the workpiece tightly.
(4) Activate the high-pressure pump assembly of the cooling system.
(5) Open the drill pipe box and drive the tool to rotate.
(6) The Z-axis feed system drives tool feed.
(7) Drill to the set position, stop cooling, retract the tool, and release the workpiece.
(8) Repeat steps (1) to (7) to process the next batch of parts.
(2) Step (7) is for CNC system control
4. Main features of machine tools
(1) Using the gun drilling process, the machining accuracy and surface roughness that usually require drilling, expanding, and reaming processes can be achieved in one drilling operation.
(2) The basic components such as the bed and box are made of high-quality cast iron.
(3) The machine tool has a servo axis that drives the tool to move longitudinally along the Z-axis.
(4) The guide rail for the movement of the drill pipe box (Z-axis) adopts a rolling linear guide rail and a precision ball screw pair transmission, which has the characteristics of high precision and long service life.
(5) Equipped with a dedicated cooling system, providing high-pressure, high flow, and high cleanliness cutting fluid for deep hole drilling.
Automatic chip removal machine: automatically removes chips and achieves preliminary oil chip separation.
Oil temperature controller: The high-power immersion refrigeration machine controls the temperature of the cutting fluid to prevent it from deteriorating.
Filtering system: mesh and precision non-woven fabric filtration, labyrinth sedimentation filtration, to improve the cleanliness of cutting fluid.
High pressure pump set: produces cutting fluid with adjustable flow rate and pressure to supply oil to the tool. Adopting a high-pressure gear pump, a pilot operated remote relief valve, and a one-way valve to avoid oil circuit vacuum caused by frequent start-up.
(6) The tool feed is achieved by using a servo motor to drive a ball screw; The tool rotation is driven by a servo spindle motor, with high speed and low noise; The feed and rotation of the cutting tool can achieve stepless speed regulation.
(7) The machine tool has functions such as pressure protection, cooling system liquid level and temperature protection, tool protection, and stroke protection.
(8) Adopting numerical control method, with high degree of automation, strong operability, high work efficiency, high precision, safety and reliability.
(9) The host is fully enclosed for protection.
(10) The connection between the tool and the spindle adopts OZ25 tool holder, which is convenient for clamping the tool.
(11) The machine tool is equipped with a foot pedal for easy operation.
(12) The CNC system control station is assembled at the front end of the machine tool; Adjustable for easy tool alignment and maintenance. The pressure regulating panel of the cooling system is located on the CNC system control station, which digitally monitors the current and frequency of the cooling motor for easy adjustment.
(13) The chip conveyor is placed behind the machine tool and equipped with a chip storage car and a storage box for filter cloth to avoid wasting cutting oil.
