• More than 21 years of experience, high quality, stable performance
• ISO, CE, SGS certified
• PLC OR CNC quenching machine line, automatic program, saves workers, improves work efficiency

• The lifting is powered by the Servo motor, position controlled by digital input with a precision of 0.1mm, providing a wider range of speed adjustment. The screw lift uses a precision ball screw, and the leading column uses a circular column structure. All pillars are thermal refined 45#, hard chromium plated to ensure no rust and no distortion, ensuring the machine's durability.
• Machine position limit is controlled by inductive proximity switches, providing safe buffering.
• The machine uses a mechanical system to avoid the heavy, large hydraulic systems, thus preventing hydraulic component leakage and accuracy reduction caused by changes in oil temperature during equipment operation. This also reduces the equipment's usage requirements, making the machine simpler and more convenient to operate and maintain, requiring minimal servicing.
• Motor-controlled top lift can be adjusted according to the length of the workpiece. A clamping table can be used to ensure normal rotation of the workpiece.
• The rotating speed can be digitally adjusted on the control panel to meet high-precision adjustment needs. This achieves the best quenching effect and quality for the workpiece.
• The cabinet position can be adjusted by the operator for easier handling and great work efficiency.
• Workpiece rotation uses an S drive, offering a wider range of speed adjustments, clear and easy control; the drive motor is located above the quench to prevent moisture damage.
• The machine is quenched by a cooling spray with a 300mm high water tank at the bottom, eliminating the need for an additional water tank and reducing installation work.
• Easy disassembly and convenient maintenance. The main electronic components are from Taiwan, ensuring long life and low maintenance cost. The system uses a full English menu with an intuitive interface for easy operation. The CNC/PLC panel allows direct input and control of quenching time, vertical speed, and rotation speed. It can store various procedures, making it easy to call up multi-stage, variable speed requirements, and complex processes.

Induction Heat Treatment Application—Quenching & More

What is induction quenching? Induction hardening is a type of surface hardening in which a metal part is heated by induction and then hardened. The quenched metal undergoes a martensitic transformation, which increases the hardness and brittleness of the parts. Induction hardening is used to selectively harden areas of a part or assembly without affecting the overall properties of the part.

What is induction tempering? Induction tempering is a form of subcritical heat treatment, mainly used to improve the ductility, toughness, and dimensional stability of the workpiece, eliminate residual stress, and obtain specific mechanical property values. Induction tempering can be performed on all hardened components such as rods, joints, and shafts. Induction tempering solutions exist in the automotive and automotive supply industries.

What is the difference between tempering and annealing? Tempering treatment is generally carried out after quenching. The heat treatment combined with high-temperature tempering after quenching is called quenching & tempering treatment. Its purpose is to increase the hardness and toughness of the workpiece and stabilize the size of the workpiece to ensure that it will not deform during use. Widely used in important structural parts of automobiles, tractors, machine tools, etc., such as connecting rods, bolts, gears, and shafts. The hardness after tempering is generally HB200-330.

Annealing is generally carried out before quenching; the main purpose is to eliminate the residual stress caused by plastic deformation processing, welding, etc., and existing in the casting, to prevent it from affecting the accuracy of the workpiece. For iron and steel products heated to 100-200°C below the temperature at which austenite begins to form, cooling in the air after heat preservation can eliminate internal stress.
