An adjustable temperature control switch is installed on the wooden box. One lead wire of the adjustable temperature control switch is connected to the live wire of the power supply. Vacuum Heat Treatment of Hollow Linear Optical AxisThe other lead wire is connected in series with the fuse and the quick-jump thermostat to the live wire position of the three-eye socket of the heating plate, the neutral position of the three-eye socket is connected to the neutral wire of the power supply, and the ground wire position is connected to the ground wire of the power supply. . There is no external electromagnetic radiation and static electricity when it is heated, and there will be no short-circuit accident when the surface encounters water.Precision gear vacuum heat treatment At the same time, it can emit far infrared rays to produce health care and physical therapy effects, and it can also achieve uniform and constant temperature heating.Martensitic stainless steel quenching vacuum heat treatment process
