The low utilization rate of China's NC Machine Tool Causes and Countermeasures(2)
The low utilization rate of China's NC Machine Tool Causes andCountermeasures(2)
2) the technical preparation of the lag in the actual machine inuse can often be seen waiting for machine downtime procedures,tools and fixtures, etc.; technical preparations did not let themachine do a good job in the beginning of processing, inevitablylead to learning by doing stop; enterprises are accustomed to usingordinary machining methods, so that the operators themselves tosolve some technical preparations, such as grinding tool such as afew.
Second, improve the utilization of CNC machine toolscountermeasures
For CNC machine tools to create a good "working environment" and"one person one CNC machine tool environment" mutual coordination,are the user make good use of the necessary conditions for CNCmachine tools.
1) CNC machine tools for more stringent power requirements, generalrequirements for working voltage 22OV ± 10%;
2) For the NC machine tool configuration suitable automaticprogramming system, fast and accurate programming CNC machine toolsis to improve the utilization of an important aspect;
3) must be equipped with the necessary accessories and cuttingtools. It should be noted that a separate contract to buy theattachment unit price is much higher than supply, together with thehost attachment unit price, qualified enterprises should buy asmuch as possible in conjunction with the acquisition of part of thehost vulnerable parts and other accessories. In an enterpriseproduction process and product mix changes are possible, such as inthe acquisition is expected to be able to make considerations,configuration necessary for attachment and knives, so that there isno need for a large machine that is able to adapt to changes inchanges in investment funds could have been avoided waste, to "onemachine to many";
4) CNC machining parts before the review process, and should payattention to the production of technical preparations, includingparts CNC machining process analysis, processing, programming,tooling and tool configuration, raw materials, test preparation andprocessing to shorten the production lead time . Reasonablearrangement suitable for use in CNC machining of various workpiece,arranged CNC machining operation required for the production aspectof the beat.
To strengthen the day-to-day maintenance of CNC machine tools, CNCmachine tools to form "repair center", are reliable and long-termuse of an important guarantee for CNC machine tools.
1) emphasis on the use of CNC machine tools to ensure thefunctioning of the initial rate. CNC machine tools, once goodafter acceptance must immediately put into operation, as far aspossible enhance the rate of machine switched on, so that thehidden fault, as far as possible be excluded from warranty. In general, the numerical control system to go through 9 to 14months of operation to enter the effective operation of period(stable phase), CNC machine tools, after around 6 - 12 monthsprobation period before normal use. In the warranty periodand the probationary period should be open enough to allow the useof machine tools so that a machine has enough of "aging"process.
2) to strengthen day-to-day maintenance of CNC machine tools.Special attention should be paid to CNC machine tools do not haveappropriate long-term archive. Has been reluctant to use CNCmachine tools, it will damp because of reasons such as electroniccomponents to speed up the deterioration or damage.
If an enterprise does not produce mission, CNC machine tools alonger period of time when not in use, but also regularelectricity, the best power per week 1 or 2 times, each timerunning around lh so that electrical components are not damp, butalso to detect whether or not battery alarm happened to prevent thesystem software, the loss of parameters.
3) set up a high level of repair teams. CNC machine toolshave a certain number of enterprises set up a high standard oftechnical staff responsible for the repair mission of the NCmachine tool maintenance organizations - such as "CNC machine toolrepair center." The director of equipment maintenanceorganizations from the direct leadership of the director, CNCmachine tool repair center members should have rich experience inrepair technicians, electrical engineers, mechanical engineers,maintenance fitters, and are highly specialized knowledge ofpersonnel, the user must the use of various forms of theirtraining, especially in CNC machine tools to enhance their abilityto identify the fault and troubleshooting ability to dealwith.
CNC machine tools technical personnel to strengthen thecomprehensive professional quality training and development of theapplication of CNC machine tools technical team are making good useof CNC machine tool users the key.
For this reason users should note the following.
1) a rigorous selection process CNC technicians. CNC machine tooltechnology are relatively intensive machine tools, operation andmaintenance more complicated. Therefore operation,programming, maintenance personnel must be carefully chosen. Under normal circumstances, the first operation, programming. Maintenance personnel should be selected with relevant professionalqualifications college technical staff as the targetculture.
2) Strengthening the technical staff of NC the overall quality oftraining. practice and training, user purchased CNC machine toolsat the same time we must consider the selection and training ofpersonnel, operation, programming, maintenance staff must gothrough professional training posts in order to operate.
3) make great efforts to train the use of CNC machine toolstechnical team and to take measures to stabilize the team. CNC machine tools using the level, not only depends on the abilityof the operator hands, but also programmers programming skills,maintenance staff repair skills are closely related.
Users should be adopted to improve the treatment of professionaland technical personnel, mobilize the enthusiasm of their work, tocreate a liberal employment environment, efforts to stabilize theteam and to maintain the CNC machine tool stability of the relevanttechnical staff.
