Diamond cutting discs for stone are designed for cutting high-strength surfaces made of natural stone, marble, granite with the passage of cuts at rotation speeds up to 80-100 m/s at a frequency of 2.8-10 thousand rpm. Such equipment is intended for installation on hand tools or stationary equipment with mounting holes 22.23, 25.4, 32 mm or metric M14.
Types and differences of diamond discs for stone
Cutting discs are a round body made of high-strength steel (the base of the equipment), along the edge of which a cutting edge of synthetic diamonds with a metal binder is brazed. The circle is reinforced in the center for better balance at high cutting speeds. The direction of rotation when cutting is indicated by an arrow based on the tooling.
For stone processing, diamond equipment with a diameter of up to 600 mm is suitable:
- stone discs with a solid cutting part are suitable for fine cutting, they are installed on stationary equipment: stone cutters, tile cutters. Used for straight cuts, there are also models for cutting at an angle of 45 degrees.
- stone discs with a turbocharged working edge give a quick cut, are installed on grinders.
- stone discs with a segmented cutting edge are distinguished by a high resource, they are used both for working with hand tools and for installation on stationary equipment.
notethat blades with a solid cutting edge are designed to produce clean cuts with the most straight edges without chipping. Such circles clog faster than segmented and turbocharged ones, which leads to a decrease in cutting speed and a reduction in resource. Segmented and turbo versions are designed for more vigorous work and provide passage up to 400-500 mm / min on stone, marble, granite.
Diamond blades for stone for dry/wet cutting
Intensive cutting of high-strength stone materials, especially with solid discs, leads to rapid heating of the cutting part, deterioration in performance or overheating. To extend the life of such equipment, alternate operation and cooling at idle is recommended. The duration of cutting in such cases is limited to 1-3 minutes, followed by cooling for 20-30 seconds.
It is much more efficient to use solid and segmented discs with water supply directly to the cutting part, which guarantees continuous cooling and operation without pauses, increases productivity and extends the life of the cutting part. Fragments of material are immediately washed out, so an even and clean cut is obtained, which is easy to visually control during operation.
