钣金加工的暴利时代已经远去，钣金加工竞争越来越严峻，制造业企业对于钣金加工的要求也随之越来越高，如何选择一家重视精密钣金加工的公司，无疑成为了制造业企业需要重视的问题！重视精密钣金加工的厂家，都会有以下三个特点，J9.com金属带来详细介绍：    一、严格遵守钣金加工的管理规范。    1、用电设备中的线缆如果出现破损的话，要及时进行修复。    2、进入车间时，作业人员不能穿凉鞋、拖鞋或高跟鞋，更不能赤脚。    3、作业人员在作业时，应认真作业，不能做与作业无关的作业。

    4、在作业过程中，操作人员应戴好防护眼镜和口罩。    5、操作砂轮和角磨机时，其周围不能有易燃易爆品，避免火花飞溅而发作火灾。    6、作业完成后，切断设备电源，并做好收尾作业。    二、严格遵守钣金加工的技术规范。    1、零件表面，应先去除氧化皮后，并且检查没有缺陷问题或损伤后，才能够进行机械加工。    2、如果没有形状公差要求的话，那么应符合GB1184-80中的规定要求，其长度允许偏差，一般应在±0.5mm这一范围内。    3、假如要进行高频淬火的话，那么其回火温度应在规则的温度请求范围内，而且要进行高温时效处理才行。    4、零件在安装前，必需要进行一些必要的查看和清洗，以免带入异物。此外，还要对其合作空隙等进行查看。    5、齿轮在安装好今后，其齿面侧隙，应契合GB10095和GB11365中的规则请求。    三、严格遵守钣金加工的工艺流程。    在钣金加工优先域，重要的两个环节是切削加工和热处理工艺；要想生产出高品质的钣金件，就要处理好这两个环节的工艺流程：    1、切削加工次序：先粗后精----先主后次----先面后孔----基面先行。    先粗后精：即是先粗加工，然后再组织半精加工，最终是精加工及光整加工。    先主后次：即是先进行一些首要加工，然后是非必须表面的加工。    先面后孔：即是先加工用作定位的平面及孔的端面，然后再加工孔，这样能够保证孔与平面的方位精度。    基面先行：即是先把精基准面加工出来，然后再进行其它面的加工。    2、热处理工序。    退火与正火：一般是在机械加工之前进行。    时效处理：一般是在粗加工前，或者是粗加工后安排一次时效处理。如果是精度要求比较高的话，那么在半精加工后，要进行一次时效处理。    调质：一般是在粗加工之后进行，如果性能要求不高的话，也可以把它作为比较终的热处理。由于钣金加工产品的应用优先域十分广泛，其下游几乎包括所有的制造业，主要行业有通讯电子行业、汽车制造业、摩托车制造业、航空航天业、仪器仪表行业、家电行业等。以上行业在选取钣金加工公司时，关键要看是不是像杭州J9.com金属一样重视精密钣金加工，严格遵守各种操作规范和技术纲优先

The era of profiting from sheet metal processing has gone, sheet metal processing competition is more and more severe, manufacturing enterprises for sheet metal processing requirements are also increasingly high, how to choose a focus on precision sheet metal processing company, undoubtedly has become a manufacturing enterprises need to pay attention to the problem! The factory that takes precise sheet metal processing seriously, can have the following three characteristics, luo gong metal brings detailed introduction: one, strictly abide by sheet metal processing management standard. 1. If the cable in the electrical equipment is damaged, it should be repaired in time. 2. When entering the workshop, operators shall not wear sandals, slippers or high heels, let alone barefoot. 3, the operating personnel in the operation, should be serious operation, not to do homework unrelated to the operation.

4. During the operation, operators should wear protective glasses and masks. 5. When operating the grinding wheel and corner grinder, there should be no inflammable or explosive materials around it to avoid spark splash and fire. 6. After the completion of the operation, cut off the power supply of the equipment and finish the operation. Strictly comply with the technical specifications of sheet metal processing. 1, the surface of parts, should first remove oxide skin, and check no defects or damage before mechanical processing. 2. If there is no requirement for shape tolerance, it should meet the requirements specified in gb1184-80. The allowable deviation of its length should generally be within the range of ±0.5mm. 3, if you want to carry out high-frequency quenching, then the tempering temperature should be within the temperature requirements of the rules, and to carry out high temperature aging treatment. 4. Before installation, the parts must be inspected and cleaned to avoid foreign bodies. In addition, but also to its cooperation gap and so on carries on the inspection. 5. After the gear is installed, its tooth surface clearance shall conform to the requirements of GB10095 and GB11365 rules. Three, strictly abide by the sheet metal processing process. In the field of sheet metal processing, two important links are cutting and heat treatment. In order to produce high quality sheet metal parts, it is necessary to deal with the process flow of these two links: 1, cutting order: first rough then fine -- first master and second -- first face and then hole -- base face first. First rough and then fine: that is, the first rough processing, and then the organization of semi-finishing, and finally finishing and finishing processing. The first master after the second: that is, first some of the first processing, and then non - surface processing. Front and back hole: that is to first process the plane used for positioning and the end face of the hole, and then process the hole, so as to ensure the azimuth accuracy of the hole and the plane. Base plane first: that is, the first fine datum surface processing out, and then other surface processing. 2. Heat treatment process. Annealing and normalizing: usually before machining. Aging treatment: generally before rough processing, or after rough processing to arrange a aging treatment. If it is high precision requirements, then in the semi-finishing, to carry out a aging treatment. Tempering and tempering: generally after rough machining, if the performance requirements are not high, it can also be used as the final heat treatment. Because the application field of sheet metal processing products is very extensive, its downstream almost includes all the manufacturing industry, the main industries include communication and electronics industry, automobiles manufacturing industry, motorcycle manufacturing industry, aerospace industry, instrumentation industry, household appliances industry and so on. The above industries in the selection of sheet metal processing company, the key is to see whether like hangzhou luogong metal attaches importance to precision sheet metal processing, strictly comply with various operating standards and technical guidelines.
