Troubleshooting Of Segment Discs

Face Wobbling

Reasons:
  • Deformed core
  • Face wobbling of clamping and supporting flanges or drive spindle
  • Insufficient core hardness
  • No parallelism of tool movement relatively to material
  • Insufficient tool fixation.

Radial Wobbling

Reasons:
  • Radial wobbling of alighting spindle or adapter ring
  • A hole/alighting spindle defect
  • Uneven segment wear
  • Uneven disc or material supply during cutting
  • Spindle wear.

Core Deformation

Reasons:
  • Beating of the core
  • Jamming in the cut
  • Low cutting ability of segments
  • Loose of core hardness as a result of improper straightening or overheating
  • No hang of diamond segments over core
  • The cut depth is more than recommended; overloading when cutting.

Uneven Segments Wear

Reasons:
  • Radial wobbling of cutting tool
  • Spindle or material vibration. 

Core Cracks

Reasons:
  • Loose of core hardness as a result of overloading (deeper cut or faster supply)
  • Radial wobbling of tool
  • Jamming in cut
  • Unsatisfactory quality of core steel.

No Cutting Ability

Reasons:
  • Incorrect tool choice relative to material processed
  • Wrong cutting modes (the disc rotation frequency is too high; the cut is too deep; the supply speed is too slow)
  • Excessive water supply.

Segments Cracks

Reasons:
  • Low cutting ability of segments
  • Overloading when cutting
  • Radial wobbling of the disc.

Loss Of Segments

Reasons:
  • Jamming in the cut
  • Unsatisfactory attachment to the core (brazing, welding)
  • Overheating in the zone of cutting because of insufficient water supply
  • Core deformation.

Core Wear In Zone Of Segments Attachment

Reasons:
  • Incorrect tool choice relatively to the material processed
  • Core abrasion because of no overhang of segments
  • Non-effective water run-out of abrasive sludge from the zone of cutting
  • Face wobbling.

Excessive Noise, Vibration

Reasons:
  • Polishing of the segment diamond layer as a result of incorrect cutting modes
  • Wear of spindle bearing; insufficient tightness of discs mounting on equipment
  • The material processed is not fixed
  • Loss of core hardness
  • Loss of segments.

Jamming In Cut

Reasons:
  • The material processed is not fixed
  • Damping of the material cut parts
  • No parallelism of discs movement and the material processed
  • No perpendicularity of the alighting flange face and the working table surface
  • No segments overhang
  • Core deformation.

Excess Segments Wear

Reasons:
  • Incorrect tool choice relatively to the material processed
  • Wrong cutting models (the discs rotation frequency is too low; the cut is too low; the supply speed is too fast)
  • Radial/face wobbling.
