1000KN Marking Force CNC Angle Steel Drilling And Marking Machine Line 9 CNC Axes

Product Usage:

This equipment is primarily designed for drilling and stamping large-dimensional, high-strength angle steel utilized in transmission line towers. All holes required on the angle steel can be processed on this production line, featuring superior hole quality, precise positional accuracy, as well as high production efficiency and automation levels.

Main parameters:

Product Features:

1. Superior drilling efficiency and hole-forming precision

The drilling assembly is furnished with six CNC drilling heads, with three integrated into each flange of the angle steel. Holes featuring identical diameter and end distance on both flanges can be concurrently drilled by corresponding bilateral drilling heads.

The drilling spindle incorporates a Taiwanese BT40 precision spindle (with internal cooling), while the drilling head utilizes a cemented carbide drill bit. This configuration enables a cutting speed of up to 200m/min—markedly higher than the 25-35m/min typically achieved by standard high-speed steel twist drills—thus ensuring rapid operation.

The CNC drilling power head is driven by a servo motor, with its rapid advance, working feed, and rapid retraction controlled and automated by the CNC system. The retraction position of the drill bit can be pre-set via the host computer, reducing idle travel and further enhancing production efficiency.

Holes produced boast a diameter tolerance of less than 0.1mm and a surface finish (Ra) of less than 6.3μm, underscoring exceptional hole processing quality.

2. The drilling spindle is integrated with a disc spring automatic tool-drawing mechanism and a hydraulic cylinder for tool release, facilitating highly convenient replacement of tool shanks. The front section of the spindle features a labyrinth-style protection system, a waterproof design, and is equipped with an air curtain device—all of which collectively prevent cutting fluid from infiltrating the interior of the spindle.

These specimens encompass a range of common specifications and hole patterns of angle steel employed in transmission line towers. They enable potential users or inspectors to visually validate the equipment’s performance, thereby offering a tangible and intuitive reference for evaluating its fitness for practical production requirements.​

It is primarily designed for drilling and stamping large-size, high-strength angle steel utilized in transmission line towers, and finds extensive application in various scenarios within the construction and maintenance of power transmission infrastructure.​

In the construction of ultra-high voltage (UHV) transmission lines, where towers need to withstand extreme weather conditions and heavy loads, this equipment plays a crucial role in processing the angle steel components that form the main framework of the towers. It efficiently handles the drilling and stamping tasks for the angle steel used in the tower bodies, cross-arms, and other key structural parts, ensuring precise dimensions and strong connections to guarantee the overall stability of the towers.​
