Product category: Grinding machines for tubes

Tube grinding machine

A tube is transferred from a transverse table to the entry line formed by oblique rubber rollers. The tube is conveyed by a specified speed towards the grinding machine.
The grinding machine is formed by several frames equipped with abrasive belts. The belts are pressed to the tube depending on the required material reduction of the tube surface.
Abrasive belt grinding is a wet process. At the discharge end the tube is dried by air flow.
After the grinder passes through the entire length of the tube, the tube stops at the exit conveyor.
The tube is transversally discharged on the oblique table or towards further processing.

Tube parameters:
Tube diameter:           up to 90mm
Grinding speed:             up to 25m/min
Surface quality after grinding:      up to Ra 0.4 µ

Tube packaging machines

Packaging machinery is used for the automatic packaging of tubes into four-or hexavolumes.
Tubes or rods are automatically stored in layers of prepared ramen. According to the required dimension of the volume is created.
According to the specified dimensions of pipes and tubes on the cycle of entry is designed a machine that provides smooth automatic packaging without operator intervention.

Automatic packaging of tubes to a volume can be supplemented with the following devices:

  • automatic or manual strapping, steel or plastic tape
  • automatic weighing a volume
  • packaging volume in foil
  • storing of finished volumes on chain tray for the removal of a gantry crane
After the volume the volume can be considered binding and save on pushdown transverse conveyor.

Tube sawing and tube cutting machines

We perform cutting of tubes, having a diameter of up to 120 mm,to exact lengths by disc saws.

The tubes are put transversally between clamping jaws by handlers. The jaws are furnished with a plastic coating to avoid damage of the tube surface.By means of hydraulics tubes are clamped in jaws and the cutting of the tube starts from below with a disc saw blade of a diameter of 450mm.

Shift of the disc saw blade against the tube is program-optimized so that the shift speed is not constant. The disc saw blade is emulsion-lubricated.

After cutting the tube is relieved and transversally transferred to the storage table or to further conveying.
After setting the exact length of the tube after cutting one saw is fixed and two or more saws are travelling, placed on the linear guidance system. After setting the required length of the tube the travelling saw moves to a cutting position.
This way the tube can be cut to the exact length with trim of ends and at the same time into two or more parts.
