Before testing the accuracy, ensure that the machine tool spindle accuracy, tool holder accuracy, and tool accuracy are all correct and within the normal value range before the collet accuracy can be measured.Incorrect assembly may damage the accuracy of the collet chuck and may cause damage to the nut. Only use matching collet chucks to assemble the nut. Do not clamp tools that exceed the clamping range. | Product Name | CNC High Precision Milling Tool Holder | Material | High-quality steel 20CrMnTi |
