50~220mm Range Of Accurate Distance CNC Angle Drilling Machine BT40 Drilling Spindle

Product Usage:

This production line is purpose-engineered for the drilling and stamping of large-dimension, high-strength angle steel employed in transmission line towers. All requisite holes on the angle steel can be machined on this line, delivering superior hole quality, high positional precision, as well as excellent production efficiency and advanced automation functionality.

Main parameters:

Product Features:

1. High level of automation. The production line is outfitted with an automatic loading device (including a transverse feeding channel and a rotating loading rack), an automatic unloading device, and an automatic feeding device. All holes and steel grade markings on the angle steel can be processed in a single pass through the production line, and no manual intervention is required during the processing process—this significantly reduces the labor intensity of workers.

2. The upper computer features a Chinese interface, which is user-friendly for general operators. It is capable of displaying workpiece graphics and the coordinate dimensions of hole positions—this facilitates verification. Additionally, it can accept workpiece processing programs generated by release software. The adoption of upper computer management significantly streamlines the storage and retrieval of programs.

3. The drilling spindle is equipped with a disc spring automatic tool clamping mechanism and a hydraulic cylinder for tool release, which enables convenient replacement of the tool shank. The front section of the spindle adopts a labyrinth seal protection structure, a waterproof design, and is fitted with an air curtain device—these configurations ensure that cutting fluid does not penetrate into the interior of the spindle.

4. The hole-making process achieves high positional accuracy. The feeding device of this production line is driven by a servo motor and operates via a gear-rack transmission system. It is also equipped with a gear-rack detection assembly and a position-sensing encoder for positional accuracy feedback, forming a full closed-loop control mechanism. Meanwhile, the movement of the drilling power head along the two flank directions of the angle steel is driven by a servo motor and transmitted through a ball screw—this configuration ensures high positional accuracy of the holes machined on angle steel workpieces.

These specimens encompass a range of common specifications and hole patterns of angle steel used in transmission line towers. They enable potential users or inspectors to visually validate the operational performance of the equipment, thereby offering concrete and intuitive references for evaluating whether the equipment meets the practical production requirements.

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