Advertising engraving machine tool selection factor?

1. Material factors (PVC and plexiglass)

For the cutting of PVC or plexiglass with a thickness of 5mm or less, a single-edged thread milling cutter is used. This tool has good chip removal effect and sharp edge, but the strength is poor, so it is used to cut soft PVC material. When cutting plexiglass of 10mm or more thickness, use a double-edged thread milling cutter.

2, material thickness factors

Choose tools with different blade lengths for materials of different thicknesses. Now the thickness of the material on the market is relatively fixed. For the market demand, the company has provided the cutter with the corresponding blade length. The blade lengths are: 22mm, 17mm, 12mm, 7mm, 4mm and so on. The choice of the tool should follow the principle that the blade length of the machining tool is slightly longer than the material by about 2 mm.

3, the size of the text factor

For different sizes of text, we choose the tool diameter is different, the optional knife has a diameter of Ф4mm, Ф3.175mm, Ф1.5mm, etc., under the premise that the inner R angle can meet the requirements, try to use the larger diameter tool .

4, tool loading

When the tool is loaded, the distance from the tip to the chuck is as short as possible. Under the premise that the blade is exposed, the excess part does not exceed 2 mm. If the tool is loaded longer, the cutting speed must be reduced.

When using a new tool, the cutting speed is cut at 50% of the normal speed, that is, 0.3 m/min. After the operation is smooth, it is gradually adjusted to the normal speed, that is, 0.6 m/min.
