CHL40 CNC Horizontal Lathe-Main Technical Parameters

1. Machine tool castings utilize high-rigidity, wear-resistant HT300 cast iron, produced via centrifugal casting with added pearlite and alloy metals. Castings undergo multiple tempering and aging treatments to completely eliminate internal stresses.
2. The machine tool employs a high-torque, high-speed spindle with P4-grade imported bearings. The spindle undergoes rigorous high-speed rotation testing. Servo-type spindles are standard equipment, with optional gear-driven manual-shift variable-frequency spindles available.
3. Beryllium bronze wear plates are bonded to the contact surfaces with the guideways. These plates achieve high hardness (HRC 45) after quenching and resist deformation. These plates undergo manual precision grinding to ensure ≥25 contact points per inch.
4. Machine tool guideways undergo high-frequency deep quenching heat treatment, achieving HRC ≥55 hardness for exceptional wear resistance. Precision-ground C3-grade Taiwanese ball screws ensure stable, long-lasting transmission accuracy.
