Basic features of CNC tools

CNC machining tools must adapt to the characteristics of high-speed, high-efficiency, and high degree of automation of CNC machine tools. Generally, they should include general-purpose tools, general-purpose connection tool holders and a small number of special-purpose tool holders. The tool holder must be connected to the tool and mounted on the power head of the machine tool, so it has gradually been standardized and serialized.
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.

1. Key points of grooving: radial rake angle, core thickness, helix angle, groove length, cylindrical toughness bandwidth, grinding wheel fillet, groove type requirements, etc.
2. Key points of the circumferential edge: radial relief angle, blade diameter, blade length, circumferential blade width, radial jump, inverted taper
3. Key points of the end edge: end rake angle, end relief angle, end kernel width, edge inclination, end jump
4. Key points of backlash: chisel edge, over-center amount, backlash angle, tooth expansion and exit, bottom corner arc, fusion depth, fusion angle, wheel selection, ball head slotting rake face length
5. Other key points: ball head, arc, taper, chamfer, incision, height removal, forming contour, passivation, appearance, etc.
