1C31234G01卡件,1C31234G01使用数据
它是由难熔金属的硬质化合物和粘结金属通过粉末冶金工艺制成的一种合金材料。硬质合金具有硬度高、耐磨、强度和韧性较好、耐热、耐腐蚀等一系列优良性能，特别是它的高硬度和耐磨性，即使在500℃的温度下也基本保持不变，在1000℃时仍有很高的硬度。硬质合金广泛用
有色金属，塑料，化纤，石墨，玻璃，石材和普通钢材，也可以用来切削耐热钢，不锈钢，高锰钢，工具钢等难加工的材料。
1C31234G01卡件,现在新型硬质合金刀具的切削速度等于碳素钢的几百倍。①硬度高（86-93HRA，相当于69-81HRC）;
②热硬性好（可达900-1000℃）
③耐磨性好
④硬质合金刀具比高速钢切削速度提高4-7倍，刀具寿命高5-80倍。制造模具，量具，寿命比合金工具钢高20-150倍。可切削50HRC左右的硬质合金材料。但硬质合金脆性打，不能进行切削加工，难以制成形状复杂的整体刀具，因而常制成不同形状的刀片，采用焊接，粘接，机械夹持等方法。数控加工刀具必须适应数控机床高速，高效和自动化程度高的特点，一般应包括通用刀具，通用联接刀柄及少量专用刀柄。刀柄要联接刀具并装在机床动力头上，因此已逐渐便准化和系列化。数控机床与普通机床上所用的刀具相比，有许多不同的要求，主要有以下特点，
1 刚性好，精度高，抗振及热变形小
2 互换性好，便于快速换刀
3 寿命高，切削性能稳定，可靠
零件机械加工的工艺路线是指零件生产过程中，由毛坯到成品所经过的工序先后顺序。在拟定工艺路线时，首先除考虑定位基准的选择外，还应当考虑个表面加工方法的选择，工序集中与分散的程度，加工阶段的划分和工序先后顺序的安排等问题。选择表面加工方法时，首先应根据零件的加工要求，查表或根据经验来确定哪些加工方法能达到所要求的加工精度。
（1） 工件材料的性质 如有色金属的精加工不宜采用磨削，因为有色金属易使砂轮堵塞，因此常采用高速精车削或金刚镗等切削加工方法。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,
