Three Coodinate Deep Hole Drilling Machine

What is Coordinate Deep Hole Drilling machine ?

 

Three-axis CNC linkage enables fully automated drilling command execution;

Deep holes with small diameters can be machined without the need for tool retraction.

Drilling efficiency is up to 6 times higher than conventional drill presses.

Machining diameter range: Gun Drilling: Ø3-40mm BTA: Ø18-102mm (BTA optional configuration)

Max. machining depth:3000mm Length-to-Diameter Ratio ≥100:1;

Advantages of GUANLY Coordinate Deep Hole Drilling machine：

• The bed, column, worktable and slide table are all cast from high-quality cast iron resin sand and have undergone two aging treatments to eliminate internal stress. The arrangement of the reinforcing rib plates is reasonable. Therefore, it has the advantages of high precision, long service life, strong rigidity and good precision retention.

 

• The main shaft bearing of the drill pipe box adopts high-precision angular contact ball bearings. The rear end of the spindle is equipped with a Dubolin rotary joint from the United States to provide a stable cooling supply for deep hole processing and ensure the normal cutting of the machine tool.

 

• The main shaft drive is placed at the front, which is conducive to protecting the main motor and facilitating tool changing.

 

 

• The X, Y and Z axes all adopt a structure where servo motors drive ball screws, featuring high transmission efficiency, high positioning accuracy and high repeat positioning. The lead screw bearings adopt high-precision angular contact ball bearings.

 

• The feed system adopts rolling linear guides to enhance the response speed and sensitivity of the CNC control system, achieving high positioning accuracy and repeat positioning accuracy. 

 

 

 

• The left end of the guide frame is equipped with a guide sleeve, which serves to guide, seal and remove chips from the drill bit. A drill pipe support sleeve is assembled at the right end of the guide frame to provide support for the drill pipe, which can enhance the rigidity of the drill pipe. The guide frame as a whole moves axially under the control of the pneumatic system.

 

• Drill bar support, used to support the tool bar, reduce the vibration of the tool bar, ensure uniform force distribution on the tool and stable feed. The guide rails for moving the drill pipe support adopt rolling linear guide rails, which move quickly and flexibly.

 

 

• Cooling system: It is mainly composed of a high-pressure pump set, a chain plate chip conveyor, an oil cooler, a filtration device, etc. The pressure, liquid level, oil temperature and flow rate of the cutting oil can be digitally displayed on the control station.

 

 

• The lubrication of the linear guide rail slider, lead screw nut and main shaft used for the movement of the drill pipe box is uniformly supplied with oil at regular intervals and in fixed quantities by the automatic lubrication pump station. And it has a low liquid level alarm function.  

 

 

 

• The machine tool is protected by sliding protective doors, which facilitate the loading and unloading of workpieces. The leak-proof design of the sheet metal structure has improved the quality of the working environment.
