Textile

Textile machinery is not the first industry that comes to mind for deep hole drilling, but it uses more drilled components than you would expect. Rollers, spindles, and guide shafts all need through-holes for heating, cooling, or weight reduction. I have worked on textile machinery components from machine builders in Europe and Asia. The work is similar to general long shaft drilling but with some specific requirements driven by the high-speed, continuous operation of textile production lines. See also textile heated roller drilling and textile spindle shafts gun drilling for component-specific details. ...

Textile finishing machines use heated rollers for drying, heat-setting, and calendaring fabrics. These rollers need a through-hole that allows heating oil to circulate through the roller body. The bore must be smooth and clean so the oil flows freely and transfers heat evenly. In my experience, the quality of the through-hole directly determines the thermal uniformity across the roller face, which affects fabric finish quality. Roller Specifications and Material Considerations A typical heated roller is 2-4 meters long with a 40-80mm through-hole. The roller diameter is usually 200-400mm. The material is mild steel or stainless steel, depending on the application. Stainless is common for wet finishing processes where corrosion resistance matters. ...

The Geometry and Function of Textile Spindle Shafts Textile spindle shafts are long, thin shafts that rotate at high speeds. Many have a through-hole for lubrication or weight reduction. A typical spindle shaft might be 500-1000mm long with a 10-20mm through-hole. I have worked with shafts up to 1,500mm in length that required an 8mm through-hole. Those are the most difficult jobs because the length-to-diameter ratio exceeds 180 to 1. ...
