Thin-cutting saw

Thin-cutting sawing technique

The thin-cutting sawing technique is used, when it comes to the production of sawn veneer with a lamella thickness of more than about 1,3 mm. These lamellas serve for the manufacturing of parquet, multi-layer wooden panels, planks, panels, music instruments, pencils, components of ski and snowboards, the construction of doors, packaging, ....

Technical method

Thin-cutting technique for frame saws

The technical principle of the saw frame contains that multiple saw blades can be clamped into a single frame, which moves up and down. The workpiece moves through the sawframe and thereby is divided into lamellas.

  • exemplary data of a Wintersteiger DSG Sonic
  • minimum kerf: 0,7 mm
  • lamella thickness min.: 1,5 mm
  • cutting accuracy: plus/minus 0,1 up to 0,2 mm (depending on the cutting height)
  • feedrate: 0,3 up to 1,7 m/min

Thin-cutting technique for band saws

Analogically to the technical principle of band saws, one lamella per saw aggregate is seperated from the workpiece-block. The horizontal configuration of the saw aggregate is a typical characteristic. Several saws, arranged one behind the other, allow more than one cut per workpiece throughfeed.

  • Exemplary data of a NEVA RE-MAX 500 CNC
  • minimum kerf: 1,25 mm
  • lamella thickness min.: 2,0 mm
  • feedrate: 5 up to 60 m/min

Technique of circular saws / cleaving saws

Cleaving saws are offered as single machines or as additional equipment for moulders and provide high values regarding precision and feedrate. The comparatively low workpiece dimensions on the other side lead to limitations.

Comparison of the methods

Accuracy: Because of the high level of pre-stressing and stiffness of the frame saw blades the thickness tolerances, the kerfs as well as the minimum thickness of the lamellas are lower than lamellas that were produced by means of the band sawing principle. Advantages among others: Material savings and less or no rework necessary (for example by calibration sanding), cleaving saws can be equipped with scoring saws, which leads to tear-free cuts.
  • Frame saws: up to 2 m/min
  • Cleaving saws: up to ca. 40 m/min
  • Thin-cutting band saw: within the high-speed range up to ca. 60 m/min
Workpiece dimensions:
  • The band sawing technique offers the least limitations regarding height and width of the workpiece. The length of the saw blades and the deflection rollers have a positive effect on the cooling behaviour of the tool.
  • Special cleaving saws process raw workpieces from a length of ca. 250 mm and up to a width of ca. 150mm. (example: Schroeder S-4)
  • The max. workpiece thickness for thin-cutting frames is ca. 260mm - in individual cases also more than that (Wintersteiger DSG 200/400).
Wood moisture:
  • The band sawing technique reacts more insensitively to wet wood. For applications in the flooring area sawn veneers are cut generally out of dried wood.
Required space:
  • Thin-cutting frame saws and cleaving saws contain a very compact machine technology with comparatively low space requirements. The band sawing technology on the other side requires the greatest space.
