Tips for using flat-bottomed sharp knife of engraving machine

1) The material does not require high linear speed: as we said above, when processing red copper, aluminum alloy and other materials, the version should be processed with a flat-bottomed knife. This is because this type of material does not require very high linear speed during processing, and the effect of linear speed on tool life is not very obvious. At this time, we use flat-bottomed knives for processing.
2) During finishing, some positions need to be processed with flat-bottomed knives: the accuracy of self-grinding bull nose knives is generally difficult to guarantee, so finishing cannot be performed. The accuracy of flat-bottomed knives is relatively better guaranteed.
In addition, flat surfaces, vertical walls and intersections at right angles can only be processed with flat-bottomed knives.

The difference between folding drill bits

HSS drill bit-tip angle is generally 118 degrees, sometimes greater than 130 degrees; the blade is sharp; the accuracy (blade height difference, symmetry, circumferential runout) is relatively low. There are many ways to repair chisel.

HM drills-the top angle is generally 140 degrees; straight flute drills are often 130 degrees, and three-edged drills are generally 150 degrees. The blade and the tip (on the edge) are not sharp and are often dulled, or called inverted edges and chamfers; high precision is required. Chisel blades are often repaired into an S-shape to facilitate chip breaking.
