A court in Hunan City entrusted our company to conduct quality analysis on the "dual-spindle CNC machine tools" involved in the case. The purpose of the quality appraisal analysis of the dual-spindle CNC machine tools is as follows:
The supplier and the buyer signed a "Product Order Contract", which stipulated that the demander would purchase two dual-spindle CNC machine tools (model ***) from the supplier and the acceptance standards. After the
equipment was delivered to the location designated by the purchaser, multiple collisions occurred during the supplier's debugging process. The chuck and spindle were damaged, and the efficiency of the parts was low. The equipment could not meet the agreement between the two parties, causing the equipment to be shelved and not put into use.
Therefore, the buyer believes that the dual-spindle CNC machine tool has quality problems. The supplier stated that the claws, clamping mechanisms, CNC programs and other processes of the two equipment are specially designed for the demander's parts.
Therefore, it is normal for some problems to occur during the debugging process. The supplier had proposed improvement plans for these problems, but they were shelved because the two parties could not agree on the time to complete debugging.
In order to clarify whether there are quality problems with the "double-spindle CNC machine tool" involved in the case, the buyer filed an application for quality appraisal of the "double-spindle CNC machine tool". The
analysis expert group conducted a discussion and comprehensive technical analysis on the relevant information, on-site investigation and testing data of the "dual-spindle CNC machine tool" involved in the case, and made the following quality appraisal analysis opinions of the dual-spindle CNC machine tool:
( 1) The appearance inspection, acceptance of the standard specifications of the machine body, and 24-hour no-load operation of the two "dual-spindle CNC machine tools" involved in the case are all in compliance with the "Product Ordering Contract";
(2) The technical information of the two "double-spindle CNC machine tools" involved in the case only includes operating instructions, The equipment packing list and the machine tool accuracy check list, a total of three items, do not comply with the agreement;
(3) The "double-spindle CNC machine tool" involved in the case can work normally after replacing the "clamping device", and the accuracy of some parts processed does not meet the agreement. The main reason is that the existing equipment involved in the case has The machining process plan cannot meet the parts manufacturing requirements;
0 (4) Under the existing process plan, the "dual-spindle CNC machine tool" involved in the case failed to produce qualified parts, and it is not appropriate to determine the "processing cycle" time, but the main spindle and sub-spindle completed the process in 40 seconds. The time interval between two consecutive completed parts is 1 minute and 13 seconds.
