Bull Nose Center

      Live centers are the most widely used products in various turning lathe.In recent years, there has been intense internal competition in the product market, with quality being overlooked. The products of some manufacturers are often complained about by customers. Live centers are becoming less durable and less accurate, wasting resources and turning into junk products.The reasons for the less durability and accuracy of live centers are the failure to ensure the precision of product components. Many companies after installing the centers, rely on grinding the tip of the live center to obtain short - term product measurement accuracy. Such live centers not only lose accuracy after just a few days of use but also damage the machine and the processed products due to the misalignment of the bearings.
