Optimized solution for processing Sandvik Coromant wind power equipment

Traditional tool solutions are often based on the performance of the tool, but they are often constrained by factors such as machine tool equipment, tooling fixtures and the rigidity of the workpiece itself, thus failing to achieve the expected processing cycle and life, allowing customers to invest in the initial production budget and later The actual processing effect is very different and the effect is not satisfactory.

Taking the Chinese wind power supporting industry, which has sprung up in recent years, as an example, in view of the particularity of wind power components, how can we best balance the various factors involved in the processing of wind power equipment, and further propose the best processing technology for wind power component manufacturers? The deep-level recommendations are undoubtedly very popular with users. And the Swedish tool solution provider Sandvik Coromant is worth learning in this regard. Based on the full discussion with the machine tool manufacturers, the company's performance of the tool products is more fully demonstrated on the machine. In the following, we will focus on the processing of components such as hubs, spindles, slewing bearings, and some excellent machining solutions for wind power generation equipment, and explain how Sandvik Coromant is aimed at users in the wind power industry.

Wheel processing

Conventional hubs can be divided into two parts: the main shaft system and the vane hole system. In order to obtain the optimal input-output ratio, it is an ideal choice to use vertical and planer boring and milling.

1. Vertical processing

The use of vertical car processing rotary hole system has always been the most economical and efficient processing method. Since there are some pin holes or threaded holes in the end face of the spindle hole, in order to avoid re-clamping, the recommended vertical car should have the function of drilling and milling. The drilling and milling head usually needs to be equipped with internal cooling device to ensure drilling. effectiveness. For the vertical car interface, Sandvik Coromant's modular quick-change tool system Capto performance is outstanding, the advantage is that its high strength can ensure the efficient completion of the inner hole, end face and other turning.

2. Planing boring and milling machine processing

For hubs that machine the angle between the blade and the main shaft, the planer boring and milling machine needs to be equipped with a special clamp. The angle of the clamp is the same as the angle between the blade and the hub, and the blade position is rotated automatically or manually. Here, the boring and milling machine is also required to have internal cooling, the coolant pressure is above 1Mpa, and the machine speed is above 2000r/min, mainly considering the efficient processing of a part of the smaller diameter holes.

For such machines, power is generally not a problem. The most important thing is whether the output curve of power and torque can meet the requirements of high-efficiency machining of the tool. For example, the blade holes are generally more than 1 meter in diameter, which is traditionally processed by rough boring. The torque requirement of the machine tool is very large, but the torque output is very small at low speed. In order to solve this contradiction, it is better to use the interpolation milling method for the roughing of large holes.

PET Filament Nonwoven Geotextile

Polyester nonwoven filament geotextile made from virgin PET(polyester) chips, the continuous filament was extruded from PET chip by machine directly by spun bound process, and then punch together to get the stable 3D with higher strength fabric. So, it has high strength, good creep property excellent and erosion resistance aging-resistance, filtration, reinforcement and heat resistance.
