1C31234G01卡件,1C31234G01使用數(shù)據(jù)
它是由難熔金屬的硬質(zhì)化合物和粘結(jié)金屬通過粉末冶金工藝制成的一種合金材料。硬質(zhì)合金具有硬度高、耐磨、強度和韌性較好、耐熱、耐腐蝕等一系列優(yōu)良性能，特別是它的高硬度和耐磨性，即使在500℃的溫度下也基本保持不變，在1000℃時仍有很高的硬度。硬質(zhì)合金廣泛用
有色金屬，塑料，化纖，石墨，玻璃，石材和普通鋼材，也可以用來切削耐熱鋼，不銹鋼，高錳鋼，工具鋼等難加工的材料。
1C31234G01卡件,現(xiàn)在新型硬質(zhì)合金刀具的切削速度等于碳素鋼的幾百倍。①硬度高（86-93HRA，相當于69-81HRC）;
②熱硬性好（可達900-1000℃）
③耐磨性好
④硬質(zhì)合金刀具比高速鋼切削速度提高4-7倍，刀具壽命高5-80倍。制造模具，量具，壽命比合金工具鋼高20-150倍。可切削50HRC左右的硬質(zhì)合金材料。但硬質(zhì)合金脆性打，不能進行切削加工，難以制成形狀復(fù)雜的整體刀具，因而常制成不同形狀的刀片，采用焊接，粘接，機械夾持等方法。數(shù)控加工刀具必須適應(yīng)數(shù)控機床高速，高效和自動化程度高的特點，一般應(yīng)包括通用刀具，通用聯(lián)接刀柄及少量專用刀柄。刀柄要聯(lián)接刀具并裝在機床動力頭上，因此已逐漸便準化和系列化。數(shù)控機床與普通機床上所用的刀具相比，有許多不同的要求，主要有以下特點，
1 剛性好，精度高，抗振及熱變形小
2 互換性好，便于快速換刀
3 壽命高，切削性能穩(wěn)定，可靠
零件機械加工的工藝路線是指零件生產(chǎn)過程中，由毛坯到成品所經(jīng)過的工序先后順序。在擬定工藝路線時，首先除考慮定位基準的選擇外，還應(yīng)當考慮個表面加工方法的選擇，工序集中與分散的程度，加工階段的劃分和工序先后順序的安排等問題。選擇表面加工方法時，首先應(yīng)根據(jù)零件的加工要求，查表或根據(jù)經(jīng)驗來確定哪些加工方法能達到所要求的加工精度。
（1） 工件材料的性質(zhì) 如有色金屬的精加工不宜采用磨削，因為有色金屬易使砂輪堵塞，因此常采用高速精車削或金剛鏜等切削加工方法。due to the requirements of electromagnetic compatibility. Among them, the common mode chip inductor is a commonly used device, which is used by many industrial switches. What I wonder is that the common mode chip inductor, which has only four solder joints and is not small, often fails to weld, resulting in the failure of power on of the equipment, and low-level errors will be made in machine welding. In addition, the breakdown or leakage of some anti surge devices such as varistors and TVs tubes will also cause the equipment to fail to power on. Of course, the problem of power converter is the most direct. The failure of switching power supply, power module and filter is also common. Their fault phenomena include input short circuit, input overcurrent, no output, output undervoltage or immovable load. The development of industrial Ethernet technology, the large demand of downstream transportation, power and other users, the continuous enrichment of product supply in the middle and low-end market, and the wider application of network management switches are the direct reasons for promoting the development of the market. In the domestic industrial Ethernet switch market, power and rail transit are the key application fields of industrial switches,
