- Applicable to pipes turning.
- The tailstock pressure of lathe adjusts to six to ten kilograms. (for reference)
A bull nose center is a type of lathe center designed for supporting large, hollow workpieces such as pipes and tubing during machining. Unlike regular live centers, bull nose centers have a larger, conical shape that fits into the hollow end of the workpiece, providing stability and support during operations. They are commonly used in both metal and wood lathes for heavy-duty applications. These centers are particularly useful in environments where workpiece weights and machining forces are extreme, such as in oil field maintenance, power generation component manufacturing, and pipe manufacturing.
Li-Hsun's BC Type Bull Nose Center is designed for machining larger inner diameters, hollow, or concave workpieces. Its rounded front end provides better support and contact with the workpiece surface. The bull nose design helps prevent scratches or damage to the workpiece surface, especially when handling softer materials or finished surfaces. Our products are available in sizes ranging from 2 inches to 12 inches.
Crafted with a hardened Cr-Mo steel tip (HRC 60° ± 1°), Li-Hsun's bull nose center ensures durability and resistance to wear during demanding applications. Key features include a combination of taper roller bearings and ball bearings, offering superior load capacity and smooth rotation. Li-Hsun is a professional bull nose center manufacturer in Taiwan. Please feel free to contact us if you require further information.
◆Bull Nose Center Selection Guidelines:
Choose the appropriate size based on the workpiece dimensions and Morse taper requirements. The angle of the bull nose head varies depending on its size, so special attention is needed when selecting the product.
If standard models do not meet your needs, we offer customization services. We can manufacture bull nose centers according to customer-provided drawings, including specific dimensions and angles.
