在保证刀具有足够强度的前提下，应选用较大前角，这样不仅能够减少被切削金属的塑性变形，而且可以降低切削力和切削温度，同时使硬化层深度减小。车削各种不锈钢紧固件的前角大致为12～3，对马氏体不锈钢紧固件（如2Cr13），前角可取较大值，对奥氏体和奥氏体+铁素体不锈钢紧固件，前角应取较小值。对于未经调质处理或调质后硬度较低的不锈钢紧固件，可取较大前角；规格直径较小或薄壁件，宜采用较大的前角。切削用量的选择切削用量对加工不锈钢紧固件时的加工硬化、切削力、切削热等有很大影响，特别是对刀具耐用度的影响较大。
火灾中矿用电缆的主要特性有火灾温度一般在600℃～8000℃，在火灾情况下，导线电缆会很快失去绝缘能力，进而引发短路等次生电气事故，造成更大的损失；导线电缆在规定的允许载流量下有较大的过载能力；短路状态下，导线电缆会在瞬间引起绝缘材料熔化、燃烧，并引燃周围可燃物。
矿用通信电缆结构：1、导线：退火裸铜线，铜线直径为0．30，0．42，0．52，0．60，0．70，0．80，0．90(mm)。 2、绝缘材料：高密度聚乙烯或聚丙烯，按照全色谱标准标明绝缘线的颜色。 3、绝缘线对：把二根不同颜色的绝缘线按不同的节距扭绞成对，并采用规定的色谱组合以便识别线对。 4、通信电缆缆芯结构：以1对为基本单位，超过25对的电缆按单位组合，每个单位用规定色谱的单位扎带绕扎，以便识别不同的单位。100对及以上线对的电缆加有1％的预备线对，但最多不超过6对。缆芯内的间隙用石油膏填充。 5、缆芯包带：用聚脂薄膜带绕包。 6、屏蔽：铜丝屏蔽或用轧纹(或不轧纹)金属带，金属带纵包于通信电缆缆芯包带之外。 7、护套：蓝色低密度聚乙烯。也可提供双层护套的通信电缆。
Precautions for installation of power cables: keep 2m distance when the cable is installed in parallel with the thermal pipe, and 0.5m should be maintained when crossing. The cable shall be installed at a distance of 0.5m in parallel or across other pipelines. When the cable is directly buried and installed, the buried depth of 1-35kv cable is not less than 0.7m. When 10KV and below cables are installed in parallel, the net distance between them shall not be less than 0.1m and 10-35kv shall not be less than 0.25m. The distance of cross installation is not less than 0.5m. Cable laying temperature is not lower than 0 ℃, bending radius: multi-core cable or 15 (D + D), a single cable 20 or more (D + D), (D for cable diameter, D) for the conductor diameter. 6 kv and above cable joint: (1) installing a cable terminal head, must be stripped semiconductor electric shielding layer, operation shall not damage the insulation, should avoid mark uneven situation, when necessary use sand paper to grind; The shield end should be flat and the graphite layer (carbon particles) should be cleaned. (2) plastic cable end copper tape screened and armor must be good grounding, the short circuit also follow this principle, avoid unbalanced three-phase run ShiGang armoured end produce inductive electromotive force, and even "lighter" and accidents such as burning sheath. It is required to use my tinplate to braid copper wire for grounding lead. When connecting with the cable copper belt, it should be welded with chromium-iron tin. The shield of three-phase copper tape should be connected with ground wire respectively. Note that the shielded ground wire and steel armor ground wire should be separately drawn out and insulated from each other. The position of the welded ground wire should be as low as possible. Basic requirements for cable terminals and intermediate joints: a. good conductor connection; B. The insulation is reliable, and it is recommended to use irradiated cross-linked heat-shrinkable silicone rubber insulation materials; C. good sealing; D. sufficient mechanical strength to meet various operating conditions. The end of the cable must be used to prevent erosion of water and other corrosive materials, so as to prevent breakdown due to the aging of the insulation layer caused by water trees. Crane or forklift should be used for the loading and unloading of cables. It is forbidden to run flat or lay flat. For installation of large cables, cable laying cart should be used to avoid external damage or abrasion caused by manual dragging. If the cable cannot be laid in time for some reason, it should be stored in a dry place to prevent sunlight from exploding and water entering the end of the cable. Note: the installation of wire and cable should be done by the installation personnel or full-time technical personnel familiar with the performance of wire and cable. If there are still unclear matters, please consult the relevant technical department or the technical department of our factory.

只有保持镀液高度清洁,才能减少故障、减少返工、提高质量、降低综合成本、提高市场竞争能力。除镀液杂质镀液中难免会产生、积累各种有害的杂质。当其超过允许值,则带来各种故障。去除杂质有几种情况:通过过滤直接去除各种机械杂质。通过转化形成的机械杂质,过滤后去除。酸铜液中过多的Cl-与Cu+形成CuCl沉淀,镀镍或氯化物镀锌液中的Fe3+形成Fe(OH)3沉淀,HEDP镀铜液中的Fe2+形成Fe(OH)2沉淀等。
