High Speed CNC Angle Drilling and Marking Machine Production Line for Steel Tower

About High Speed CNC Angle Drilling and Marking Machine Production Line for Steel Tower

1. High drilling efficiency and hole making quality.   The drilling unit is equipped with six sets of CNC drilling heads, three sets on each of the two wings of the angle.   The holes of the same diameter with the same end distance on both wings of the angle can be drilled by the corresponding drilling heads on both sides at the same time.   The drilling spindle adopts Taiwan BT40 precision spindle (internal cooling), and the drilling head adopts cemented carbide drilling head, the cutting speed of the drilling head is up to 200m/min (the general high-speed steel twist drill is 25-35m/min), which is given to the fast speed.   The servo motor drives the CNC drilling power head to feed, and the fast forward, work-in and fast backward of the drill are controlled by the CNC system and automatically completed.   The backward position of the drill can be set in the upper computer, which reduces the empty stroke and further improves the production efficiency.   The tolerance of the hole diameter of the manufactured hole is less than 0.1mm, the hole finish Ra is less than 6.3m, and the processing quality of the hole is high.

i141i14The spindle motor of the drilling unit adopts high-quality inverter motor, and the maximum spindle speed is up to 6000 r/min.

i142i14Drill pipe feed speed of about 40 m/min (adjustable).

i143i14The spindle and other stressed parts should be forged, heat-treated and non-destructively tested according to the standard, with sufficient strength, hardness and wear resistance, and high fatigue strength to meet the requirements of long-term feeding and rotating work.

i144i14In order to ensure the working accuracy of the equipment, the spindle deflection should be less than 1/1000 span in all cases of maximum load.

i145i14The spindle feed distance has an adjustable compensation function.

i146i14The upper and lower limit positions of the drilling unit power head's collinear movement are provided with travel switches as limit protection.

i147)  Unit power head in addition to the installation of limit switch protection in addition to the control system for its limit position should also have a soft limit protection.

2. The drilling spindle has butterfly spring automatic tool pulling mechanism, hydraulic cylinder loosening tool, and it is very convenient to replace the tool shank.   The front part of the spindle adopts labyrinth type protection, waterproof design and is equipped with an air curtain device, which ensures that the cutting fluid does not enter into the inside of the spindle.

Outstanding Precision and Versatility

Engineered with a positioning accuracy of 0.3 mm and processing speeds up to 1000 mm/min, this CNC angle drilling and marking machine delivers high-precision results. Its automated tool changing system, hydraulic clamps, and customizable table size make it adaptable to a wide variety of steel tower components. The robust construction ensures rigidity and stability during demanding operations.


User-Friendly and Safe Operation

Operators benefit from a large touchscreen HMI for intuitive control, supported by Siemens/Omron PLCs and an advanced CNC system. Integrated safety features include emergency stop, noise reduction to 80 dB(A), overload protection, and safety guards, ensuring a secure and comfortable working environment during continuous operations.
