  • Different thickness sanding choose

    · According to different raw material, its hardness and sanding effect demands, you can consider double or three sanding frames.

    · Working table lifting function suitable to use this machine independent or connect with line but all the boards ensure uniform thickness.

    · Sanding frame lifting function is optional that suitable to various boards thickness easily to adjust independent or within line.

  • Eccentric shaft

    Sanding axis combine seamless steel tube, eccentric shaft core with NSK bearing, through fine manufacture to ensure balance error around ±0.02mm, prevent miss or deviate sanding.

  • Aluminium alloy pad

    After hard sanding the raw material, apply this wide aluminium alloy pad to polish the surface again, remove some standing burr and make surface smooth ensure uniform thickness.

  • Independent shaft hanging slab

    Each shaft fix on independent stable hanging slab and easily to solve the sanding deviation. Just turn the screw to different direction which one round means 0.1mm rectify accurately.

  • Eccentric shaft damp lifting

    The former sanding frame apply air cylinder lifting the eccentric shaft when it's rest that can protect the boards from damaged if machine stop emergency.

  • Sanding belt adjust knob

    On the sanding frame face with knobs that can adjust the sanding belt in case of it out of central, the knobs are intuitively clear and easily to operate.

  • Sanding belt swing blowing dust

    Add the swing style blowing device near the top of sanding belt to remove dust during work, it will help to promote sanding effect and increase its lifetime.

  • Automatic thickness detect

    Supported by advanced hardware that the feeding entry with automatic detect function of each board thickness accurately.

  • Heavy air cylinder

    Heavy air cylinder with bigger diameter, better sealing effect and more durable, ensure lifting heads stably and accurately.

  • Underneath type motor

    The main and heavy motor stay low to the ground ensure working stable and reduce shacking.
