Definitions

  • the invention relates to a circular saw blade according to the preamble of claim 1, in particular for processing natural or artificial stone material, for example in the form of concrete walls.
  • the saw blade has at its periphery processing means such as cutting or abrasive or combinations thereof.
  • the cutting or abrasive means may be formed for example by diamond body, cutting teeth or a combination of both.
  • Such saw blades are determined via a central bore on the tool holder of a corresponding tool device and offset from this in operation in rotation.
  • the US 2002/123302 A1 discloses a circular saw blade having teeth disposed along the circumference and having a machining means at the tip.
  • the saw blade is not flat, but has a serpentine-like tortuous shape. This shape of the saw blade creates a greater cutting thickness and ensures that more air is supplied to the processing site.
  • a serpentine-like wound saw blade is described as advantageous for cuts in which much material is removed and low accuracy is sufficient.
  • a disadvantage of the known serpentine-like wound saw blade are the increase in the cutting thickness and thus a reduced cutting speed and the inaccuracy of the cut.
  • the present invention has for its object to avoid the disadvantages mentioned in a circular saw blade and to ensure a precise cut at low production costs.
  • this object is achieved in that at a diameter of the saw blade to 800 mm at least four sectors are provided with changing Planertonabweichungs Suiteen, wherein the Planertonabweichungs Schemee have a maximum axial runout between 0.1 and 0.2 mm, and with a diameter of the saw blade of more than 800 mm at least six sectors are provided with alternating runout areas, the runout areas have a maximum runout between 0.2 and 0.45 mm.
  • the circumferentially mutually consecutive plan run deviation ranges or the intervening Transition areas ensure a certain stiffening of the saw blade in the axial direction. As a result, the blade receives in operation a greater lateral stability, whereby a particularly precise cut is guaranteed.
  • the Planertonabweichungs Schemee cause a certain ventilation effect, which ensures better cooling of the saw blade. As a result, a decrease in rigidity due to heating of the saw blade can be reduced during prolonged operation.
  • a transition region is provided between the maximum runout deviations in each case two adjacent sectors, in which the periphery of the saw blade has a monotonous inclination relative to the median plane and extending in the circumferential direction over at least 30 °.
  • the circumference of the saw blade on a continuous waveform whereby despite the trained side impacts during operation, a very smooth running of the saw blade is achieved in the material to be processed.
  • runout areas are advantageously formed by applying the side surfaces of the saw blade with appropriately directed and energetically predetermined shocks. In this way, a particularly simple and inexpensive production of the saw blade is possible.
  • Fig. 1 shows a saw blade 2 for machining mineral materials in the form of a wall saw blade with a diameter d of up to 800mm.
  • This comprises a master sheet 4, for example made of steel, are held on the processing means 6 in the form of cutting teeth.
  • the cutting teeth can be integrally formed with the master blade 4 or at least partially formed from a special, applied to the master sheet 4 material.
  • diamond bodies can also be provided on the circumference U of the saw blade 2. It can, as in Fig. 1 indicated by dash-dotted lines, for example, diamond segments 7 may be attached to the circumference U.
  • the saw blade 2 For attachment to a tool holder of a tool device, not shown, that rotates the saw blade 2 about an axis A along a circumferential direction, the latter has a central bore 8. Further, the saw blade 2 is divided into four equal sectors S, wherein the sectors in the circumferential direction alternately have a left runout deviation range B1 or a right runout deviation range B2.
  • Fig. 2 the saw blade 2 is shown for easy understanding with excessive plan run deviation ranges B1, B2 and without processing means 6.
  • the axial runout regions B 1 and B 2 extend away from a center plane E spanned perpendicularly to the axis A.
  • all runout deviation regions B 1 and B 2 form a maximum side impact M 1, M 2, which extends from the center of a peripheral surface F of the circumference U to the center plane E and is between 0.1 and 0.2 mm, in particular 0.125 mm.
  • Fig. 2 forms the saw blade 2 at the circumference U between the maximum runout deviations M1, M2 of two adjacent sectors each extending over 90 ° transition region C, which has a wavy monotone inclination relative to the center plane E.
  • Fig. 3 and 4 show a saw blade 2 in the form of a wall saw blade with a diameter d which is more than 800 mm.
  • six sectors S are provided with runout areas B1, B2.
  • all of the runout deviations B1 and B2 form a maximum side impact M1, M2, which is between 0.2 to 0.45 mm, in particular 0.3 mm (see Figure 4 ).
  • Fig. 4 forms the saw blade 2 in this embodiment at the circumference U between the maximum runout M1, M2 of two adjacent sectors each extending over 60 ° transition region C, which has a wavy monotone inclination relative to the center plane E.
  • runout deviation regions B1, B2 takes place here by corresponding action on the saw blade 2 in the direction of the axis A with impacts of a tool, not shown, wherein the blows have a predetermined impact number and impact energy.
