Our products

Product category: Saw blades

Carbide tipped circular saw blades

from 250 to 2300 mm diameter

Cutting steel and non-ferrous metals places the toughest demands on the tool. For this purpose, Lennartz offers a wide variety of cutting edge geometries, which can be individually designed for every requirement.

In addition to the conventional cutting widths and log thicknesses, Lennartz also offers its newly developed thin-cutting technology for every application. With the same precision and stability of the saw blade, the cutting width here is reduced by up to one third. This offers the customer significant advantages such as

  • Increase in service life,
  • Material savings due to less waste,
  • significantly lower chip waste,
  • Energy savings due to reduced cutting forces; required motor power reduced by up to 40%.

Individually adapted coating concepts

Coating systems optimally adapted to the respective application are indispensable in the field of high-performance sawing technology. Thanks to its many years of close cooperation with the technology leaders in the coating industry, Lennartz can react very promptly to current development trends in the field of PVD (physical vapor deposition) hard material coating.

In cooperation with industrial users and research institutes, we are continuously developing our know-how and our manufacturing processes, so that an optimal tool design according to the special requirements and needs of our customers is guaranteed at any time.

Especially in the ECOmax product group, the carbide circular saw blades, the metal circular saws and partly also in the area of the segmental cold circular saw blades, individually adapted coating concepts find their application. Focused on economic efficiency, Lennartz guarantees tool solutions at the highest level also in the future.

Vibration and noise optimized saw blade

In close cooperation with research centers, this special saw blade was developed after a long series of tests. By inserting laser slots (vibration damping elements) in a systematic arrangement and then filling them with a filler developed for this application, it was possible to significantly reduce the decay speed and thus the noise generated during sawing compared with conventional saw blades.

Carbide-tipped circular saw blades

from 250 to 2300 mm in diameter

The machining of steel and non-ferrous metals places extreme demands on the tool. To meet These demands; Lennartz offers a wide range of geometries which can be individually designed for every requirement.

In addition to conventional cutting widths and blade thicknesses, Lennartz also offers the newly developed thin cutting technology in its product range to suit every application. Here, the cutting width is reduced by up to one third with a constant precision and stability of the saw blade. This offers significantadvantages for the customer such as

  • service life enhancement,
  • material savings through less waste,
  • significantly decreased chip waste,
  • energy savings through reduced cutting forces; the required motor power will decrease by up to 40%.

ECOmax

ECOmax saw blades are special thin-cutting circular saw blades for high-performance sawing of steel and non-ferrous metals. They are available in various designs, cutting materials and coatings. Thus, ECOmax saw blades are always individually tailored to the respective application. They are suitable for stationary mass cutting saws as well as for travelling or so-called flying saws.

HSS segmental circular saw blades

Segment saw blades with inserted toothed segments combine maximum stability and reliability with high economy. In these saw blades, the main blade is mainly made of tool steel, while the segments are made of HSS high-speed steel (material number 1.3343). The individual segments are connected to the main blade according to the tongue and groove principle, radially fastened with rivets and secured at the so-called segment joint by rivets, resulting in a closed segment rim.

Hot and cut-off circular saw blades

LENNARTZ hot and cut-off circular saw blades up to 2,500 mm diameter are high-performance tools made of proven special steel grades with strengths of 850 to 950 N/mm2. Hot and cut-off circular saw blades are used for cutting slabs, billets, sheets, tubes and profiles. Hot circular saw blades are used at cutting material temperatures > 850° C, whereas cut-off circular saw blades are used at cutting material temperatures < 250° C. Both cutting processes use the fusion cutting principle. In this process, temperatures close to the material liquefaction limit are generated in the working area of the tool due to the frictional heat. This requires a cutting speed Vc = 100 - 140 m/sec. Sufficient cooling of the press water in the tooth area must be ensured in order to flush out any material remaining in the tooth base. Depending on the cutting task, a feed rateVf = 80 - 2,000 mm/min is achieved.

Band saw blades

The base material for the bi-metal band saw blades consists of an alloyed quenched and tempered steel, which is inseparably joined to the HSS in M42 or M51 by means of laser beam welding. In further mechanical and thermal processing on modern production equipment, the uniform and reliably high quality of our bi-metal band saw blades is guaranteed.
