A caliper is a measuring tool for measuring length, inner and outer diameters, and depth. The vernier caliper is composed of two parts, the main ruler and the sliding vernier attached to the main ruler. The main scale and vernier of the vernier caliper have two sets of movable claws, which are the inner measuring claw and the outer measuring claw. The inner measuring claw is usually used to measure the inner diameter, and the outer measuring claw is usually used to measure the length and outer diameter.
Everyone must want to know why a measuring tool needs to be quenched and heat treated, and I will answer it for you. Using our high-frequency induction hardening machine to heat-treat the metal surface, the hardened layer of the workpiece after quenching is shallow, the hardness is high, the stress is small, the deformation after quenching is small, and the cracking phenomenon is greatly reduced. Quenching hardness can reach 58~63HRC. If it is processed in an old-fashioned high-frequency furnace, the service life of the workpiece is not long and it is easy to crack. Our equipment not only saves energy, but also saves man-hours, and will not pollute the environment.
The high-frequency induction hardening machine produced by our company is light, fast heating, high efficiency, especially power-saving, and the power consumption of the same load is 60% lower than that of the electronic tube high-frequency machine. It has multiple protection functions such as over-current, over-voltage, and over-heating. It is easy to operate and easy to install. It is suitable for various occasions that need to heat metal. Semi-automatic or fully automatic operation can be realized during operation.
