Recently, Wuxi Changrun's workshop has been continuously processing, with precise operation of each disc, and multiple processes including milling, drilling, and edge planing being completed in one go. At present, there are a total of 217 sets of flanges of different types and sizes, and tube sheets and baffle plates are being fully produced. These tubesheets are used in industries such as chemical, oil equipment, sugar making equipment, etc. These orders come from key enterprises in the fields of industrial economy and people's livelihood guarantee.

These flanges, tube sheets, and baffle plates are made of carbon steel, stainless steel, and titanium plates, which require very high machining accuracy. The sales department, technology department, production department, quality control department, and service departments of Wuxi Changrun coordinate with each other, strictly following customer processing requirements to ensure processing quality and timely delivery.

The reason why these customers signed a cooperation agreement with Wuxi Changrun is because of Wuxi Changrun's technical and technological strength, advanced equipment, and rich processing experience, as well as numerous cases of serving domestic and foreign customers. 

Wuxi Changrun has advanced drilling equipment at home and abroad that can serve the processing of tube sheets, including 11 deep hole drills, 31 CNC multi hole drills, and 11 CNC lathe equipment, achieving precision tube sheet machining services with high processing accuracy, complete specifications, and multiple functions. Equipped with a milling composite machining center, it has high cutting efficiency and can easily achieve functions such as turning, milling, boring, drilling, tapping, and spot facing. 

The deep hole drilling equipment of Wuxi Changrun can process a maximum drilling depth of 1200mm, with a diameter greater than 12mm but less than 55mm. It has the characteristics of stable aperture size, excellent hole wall roughness, and high verticality. It can process tube sheets with a thickness of 1200mm, achieving simultaneous dual axis and three-axis processing, with an efficiency 2-3 times that of traditional processing methods.
