Purchasing Guide

  • SK-3585H

    The 3585H is the smallest of the three flagship cutting tooth machines, primarily designed for producing liquid cooling products and accessories.

    Features: Due to the smaller size of the liquid cooling products it manufactures, it achieves the highest precision, reaching 0.05mm accuracy, while maintaining fast operating speeds.



    Selection Recommendation:

    Suitable for manufacturers with high demand for liquid cooling products and stringent requirements for precision and production capacity.

  • SK-4012H

    The 4012H is the mid-sized model among the three flagship shovel-type machines, primarily designed for producing both liquid-cooled and air-cooled products.

    Features:

    Given that air-cooled products are larger while liquid-cooled products are smaller, its worktable dimensions accommodate both types. Precision and speed are slightly lower than the 3585H.



    Selection Recommendation:

    Double shafts are supported by linear rails, which can support heavy loads and move quickly to ensure accurate positioning.

  • SK-6016

    The 6016H is the largest in size and has the largest control panel among the three main cutting machines promoted by Santai. This machine is primarily designed for large air-cooled products.

    Features: Designed for cutting large materials and producing large air-cooled products, with relatively lower precision and speed.



    Selection Recommendation:

    Suitable for manufacturers primarily producing air-cooled prod

FAQ

  • Do you accept small-batch prototyping?

    Generally speaking, the 3585H model offers the fastest speed and highest production capacity, followed by the 4012H, with the 6016H ranking last. However, the specific production capacity must ultimately be determined based on actual conditions (product drawings).

  • Can you provide engineering drawing support?

    Generally speaking, the 3585H model offers the fastest speed and highest production capacity, followed by the 4012H, with the 6016H ranking last. However, the specific production capacity must ultimately be determined based on actual conditions (product drawings).
