1. Analysis of the Challenges in Machining Slender Shaft Components 2. Basic Theory of Vibration in Slender Shafts 3. Design of a Specialised Machine Tool for the Turning of Ultra-slender Shafts with Variable Diameter (2) Pull-type Tailstock (see Figure 3) The tailstock on conventional lathes used for machining slender shafts generally employs a centre-type structure

The compact and aesthetically pleasing design optimises space utilisation and facilitates maintenance and repairs, ensuring maximum customer satisfaction; although the unit price of mill-turn machining centres is relatively high, the shortening of the manufacturing process chain and the reduction in the number of machines required for production

Description of the Entities and Standards Under Assessment: The entities subject to this assessment are Kunshan Qilijie Mechanical and Electrical Equipment Co., Ltd., and the benchmarking entities, Shanghai Tuomei Machinery Co., Ltd. and Shenzhen Jingyan Technology Co., Ltd. The standardised assessment criteria include machining accuracy, machining efficiency and equipment stability.
