Product Description

Product Description

DD25N/2 FINCM CNC Hydraulic Multi Spindle High-Speed Deep Hole Drilling Machine 2500mm*750mm

    This equipment is mainly composed of longitudinal sliding table, vertical column sliding table, double-spindle feed sliding table, worktable and bending plate, hydraulic system, cooling system, automatic lubrication system, electrical system, chip conveyor, etc.
     This DD40N/2 is mainly used for processing the holes on the tube plate of the shell and tube heat exchanger used in the petroleum, chemical, pharmaceutical, thermal power station, nuclear power plant and other industries. The maximum diameter of the workpiece is φ4000mm (need to be turned 180°), and the maximum drilling The depth is 750mm. The machine tool has high efficiency and good accuracy. The surface roughness of the drilling can reach Ra6.3~Ra3.2, the precision of the hole diameter can reach IT9~IT10, and the straightness of the hole is 0.3-0.8mm/800mm.

Equipment advantages:
1. This machine is a horizontal deep hole drilling machine.
2. The X, Y, and Z axes of the machine tool are guided by linear roller guides, which have extremely high load-bearing capacity and superior dynamic response performance, no backlash, and high motion accuracy.
3. The worktable of this machine tool is separated from the bed, and the clamping workpiece is not affected by the vibration of the bed. The working table is a casting with stable precision. The bending plate holding the workpiece is divided into two pieces, and the spacing is adjustable to adapt to workpieces of different diameters.
4. This machine tool has two spindles, which can work at the same time, and the efficiency is nearly double that of a single-spindle machine tool.
5. This machine is equipped with a flat chain type automatic chip conveyor, which is fully automatic.
6. This machine tool is equipped with an automatic lubrication system, which can regularly lubricate the parts that need lubrication such as guide rails and lead screws to effectively ensure the stable operation of the machine tool and increase the service life of each component.
7. This machine tool numerical control system adopts FAGOR8055 numerical control system, equipped with electronic handwheel, which is convenient for operation and management.
8. This machine tool has a variety of detection functions, including: 1) Spindle feed torque detection. 2) Spindle motor torque detection. 3) Flow detection. 4) Pressure detection. 5) Liquid level detection. 6) Temperature detection.
9. The machine tool's linear guide pair, ball screw pair, servo motor and its driver, planetary reducer, internal cooling joint (for gun drill), CNC system, hydraulic pump, valve and other machine tools have very high reliability. Comparable to imported machine tools, with fewer failures and high start-up rate.
