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.
