Technical features:
1The use of enlarged pallets and integral pressure plates enhances the rigidity of the pallets, making cutting smoother and more powerful. The pallets undergo secondary aging treatment, resulting in minimal thermal deformation.
2The overall structure of the bed foot is designed and manufactured in an integrated manner, using resin sand casting. After aging treatment, the deformation is small, and it has high stability and rigidity.
3Adopting double triangular guide rails, the rail performance and rigidity are better. After ultrasonic quenching, precision grinding processing is carried out, and the accuracy and precision retention are better.
