M8 The pressure roller seat technology and M8 thread bottom hole drilling fixture design 1 2 I M8 The pressure roller seat technology and M8 thread bottom hole drilling fixture design Abstract: The pressure roller seat parts processing technology and drilling fixture design is the design of process design, including machining process design and fixture three. In process design should first of all parts for analysis, to understand part of the process to design blank structure, and choose the good parts machining datum, design the process routes of the parts; then the parts of each step in the process to the size calculation, the key is to determine the craft equipment and the cutting dosage of each working procedure design; then the special fixture, the fixture for the various components of the design, such as the connecting part positioning devices, clamping element, a guide element, fixture and machine tools and other components; positioning error calculated by the a
