Precision Tools Trouble Shooting

Is the blade being handled appropriately?

The edges of hubbed blades are very thin and are easily damaged when they come in contact with another material. Please handle the blades with care.

Is the edge surface accuracy of the hub mount (flange) adequate?

Poor hub mount (flange) edge surfrace accuracy can cause runouts while the blade is rotating, damaging the blade. Please perform conditioning beforehand. For details of the edge surface conditioning, please refer to the maintenance manual.

Is there any foreign matter stuck between the hub mount (flange) and the blade?

Foreign matter stuck between the hub can cause runouts while the blade is rotating, damaging the blade. It is recommended that you clean the hub mount (flange) every time you replace the blade.

Have dressing and precutting been performed?

If dressing and precutting have not been performed or if the wear amount is too small even after they have been performed, blade dressing and truing will be poor, which can lead to failure. As a rough target, please set the dressing/precutting conditions to the below wear amount.
Hub blade: 20 μm
Hubless blade: 30 μm

Is the cutting water being properly supplied?

Cutting water not being properly supplied to the processing point can cause particles to remain on the workpiece and prevent proper cooling. Please check that there are no obstructions in the nozzle and that the cutting water is being supplied to the proper position.

Are the cutting water settings appropriate?

If the kerf width has become significantly narrower than it was at the beginning of cutting, there is the possibility that the cutting water has corroded the blade, leading it to become thinner. Blade thinning causes blade edge chipping and decreased blade strength, which can ultimately lead to failure. Please check whether there have been any changes to the cutting water additive type or concentration or the CO₂ bubbler settings.

In addition, there is the possibility that corrosion may accelerate during idling. Thus, please avoid leaving the equipment idling for a long period of time with the cutting water directed at the blade.

Is the nozzle in contact with the blade?

Contact between the nozzle and blade can damage the blade. Please be especially careful when replacing different sized blades.

Are you processing something other than a workpiece?

Processing anything other than a proper workpiece can damage the blade. Please check whether there is is any evidence of other objects being processed, such as frames and clamps.

Have any of the die moved during processing

When die move during processing, they can collide with the blade, damaging the blade. Please check whether the workpiece has been properly secured if you discover that die have moved during processing.

Have the processing parameters been changed?

Blade breakage is often caused by a high processing load due to an increased feed speed. Please check whether the processing parameters have been changed.

Have any changes been made to the workpiece?

Blade breakage can be caused by a high processing load due to workpiece thickness, film thickness, and the type of film being used. Please check whether any changes have been made to the workpiece.

Have the processing parameters been changed?

A meandering processing is often caused when the RPM/speed is increased. Please check whether the processing parameters have been changed.

Has the blade size been changed?

Too much blade exposure and/or a narrow kerf width can weaken the blade, causing the processing line to meander. Please check whether the blade size have been changed.

Is the blade deformed?

Blade deformation can prevent processing from being performed properly. Please handle the blades with care.

Is the blade properly stored?

The inner diameter of the blade may fluctuate depending on temperature and humidity. If the inner diameter of the blade shrinks due to storage environment, it may not be possible to equip the blade to the hub mount (flange). Placing the blade in the same environment as the equipment for over 24 hours before use is recommended.

- If the blade will be stored in a warehouse, storing it unopened at room temperature indoors is recommended.
- Please note that hub blades are more susceptible to temperature-induced inner diameter fluctuations because the hub is aluminum.
- Please note that resin blades are more susceptible to inner diameter shrinkage due to expansion in high-temperature, high-humidity environments because of the characteristics of the bond.

Is the hub mount (flange) dirty or scratched?

If there is adhered matter or scratching at the point where the hub mount (flange) meets the inner diameter of the blade, it may not be possible to equip the blade. Please confirm. Cleaning the hub mount (flange) each time the blade is replaced is also recommended.
