一、问题的提出为保证外径千分尺校对量杆量面的高硬度和高耐磨性,量面需要经高频淬火处理。但高频加热温度由电压、电流、栅极电流控制,而不是通过温度指示表直接表示温度。通常,操作者凭经验,根据工件加热时的颜色来估计加热温度。这洋,操作者之间时温度的估计会有误差,即使同一操作人员也会因工作时间延长而对温度的估计出现误差。因此,高频淬火处
First, the issue put forward To ensure that the outer diameter of the micrometer proofing rod high surface hardness and high wear resistance, the need for high-frequency quenching. However, the high-frequency heating temperature is controlled by voltage, current and gate current, rather than indicating the temperature directly through the temperature indicator. Generally, the operator empirically estimates the heating temperature based on the color of the workpiece when heated. This ocean, the operator between the estimated temperature will be error, even if the same operator due to extended working hours and temperature estimation error. Therefore, high frequency quenching
