Supporting Thin Materials - Mazak STX SC L PLUS CONTROL Training Manual

SUPPORTING THIN MATERIALS

When cutting thin material the sheet may sag below the level of the cutting table causing auto gap alarms or "Z-"
overtravel alarms. The following suggestions will solve this problem when it occurs.
1) Make sure that the support slats are not extremely worn. As materials are processed, the slats are gradually
wore down which lowers the height of the material. If the slats are severely worn, the material may be
sitting below the soft overtravel limit. In this case the slats must be replaced. See the MAZAK operating
manual for recommended slat drawings.
2) If the slats are in reasonable condition, there may not be enough support beneath the material. Are all of the
available slat positions used. If not, add more slats to increase the amount of support. If the material is very
thin, the final option is to cut a template to support the material.
a) Cut the part nest out of approximately 16 ga. Mild steel at a slightly larger scale (about 0.25"
larger).
b) Place the thin material over the template and cut the parts within the scaled up geometry. The
material is now elevated and the contact style profile foot is supported by rigid material.
