CS Wind Corporation is a wind tower manufacturer with global expertise, reliability, and quality. Their mission is: “We create a bright future for humans and nature.”
WHY CS WIND CHOSE BLASTING ROBOTICS
CS Wind searched for an effective method to abrasive blast the externals of new wind tower sections.
Other options considered for this project included wheel blasting technology. However, as a result of the high standards for surface cleanliness and roughness, wheel blasting was no longer an option. CS Wind chose Blastman Robotics as the partner for blasting automation.
Abrasive blast wind tower sections, fast, consistently and with minimum human labor intervention while maintaining the required specifications cleanliness and roughness that allowed the subsequent coating system to last for years.
Advantages of Automated
Considerable savings in production costs
Increased production capacity
Remarkable healthy and safety implications
Freedom to use any abrasive material
Desired surface cleanliness and roughness
Slight surface shaping by controlling the blast pressure
Working lifts and platforms are not needed
Increased fatigue strength of specific welded joints
CS Wind installed three surface treatment lines comprised of an abrasive blasting chamber and a painting room. Subsequently, each abrasive blasting chamber has one Blastman B12 robot with two ¾” nozzles.
The Blastman B12 Blasting Robot is mounted to tracks on the wall and has a 4-axis arm that can extend and swivel easily. Meanwhile, each arm supports two large blast nozzles. Typically, this robot works best on simple structures like wind towers.
Firstly, we considered material handling. We used specialized product carts. This system contains in-ground tracks and purpose-built rollers to position the tower section precisely.
Moreover, the robot is programmed to coordinate the rolling of the tower in conjunction with the blast nozzle. In this facility, blasting is done sector by sector: the robot moves from one end to the other, where the roller bed rotates the tower element. This leaves a slight overlap on the blasted sector before the robot returns. Concurrently, the tower element rotates around.
CS Wind’s North American wind tower finishing facility is highly productive, with a blast cleaning capacity of over 2500 ft2/hr using robots, which is 10x faster than manual blasting. The steel grit used for the blasting achieves the required surface cleanliness and profile, but CS Wind can easily switch abrasives for greater versatility in the long-term. Robot programming allows for five operational modes, including roller bed rotation and automatic or manual touch-up using a joystick drive.
