  • OTT+HEUGEL SAWBLADES

OTT+HEUGEL Metal Cutting Circular Saw Blades

Ott+Heuel are at the forefront of development when it comes to coated, low run out circular saw blades. A constant research and development program has been relentless in peruing the most cost effective client sawblades.

Combined with the tightest quality controls from raw material right through to the finished product, by investing in the most high tech machinery available. This enables Ott+Heugel to manufacture some of the most technically advanced sawblades on the world market. From their special side grinding process unique to Ott+heugel, includeing the most controlled heat treatment process.

Advantages of Coatings.

  • Reduces tooth wear to produce greater tool life
  • Improves quality of cut
  • Higher speeds and feed rates are achieved
  • Extremly hard surface

Concept

This PVD coating is based on the industry standard TiN that give the blade great surface hardness. This enables higher cutting rates and improved surface finish on the work piece.

Technical Characteristics

  • Surface Hardness: 2500 HV
  • Temp. of application: 500 degrees Celcius.
  • Friction coefficient: 0.65

Applications

  • Mild Steel
  • Medium Steel Alloys
  • Stainless Steels
  • Copper
  • Brass

Advantage

This is a multi-layer coating with a very low friction coefficient surface finish. This will increase cutting rates significantly. The greater surafce hardness makes it possible to work at much higher cutting rates than standard saw blades and also increases the number of cuts before regrinding.

Technical Characteristics

  • Surface Hardness: 2800 HV
  • Temp. of application: 500 degrees Celcius.
  • Friction coefficient: 0.45

Applications

  • Mild Steel
  • Medium Steel Alloys
  • Stainless Steels
  • Tool Steel
  • Titanium

Sportive

This is a multi-layer coating designed to cut the hardest materials 800N/mm2 and above, also very efficient when cutting abrasive materials like cast iron when there is a need to cut without coolants.

Technical Characteristics

  • Surface Hardness: 3000 HV
  • Temp. of application: 500 degrees Celcius.
  • Friction coefficient: 0.55

Applications

  • Medium Steel Alloys
  • Stainless Steels
  • Tool Steel
  • Cast Iron

SUPATEC

High Performance Special Coated Blades

Trends in today’s tube industry are directed towards more demanding standards, especially those in the processing of stainless steel tubes, more and more modern and fully automatic sawing machines are now being used.  For this reason, the cost of the saw blades is not the most important factor, but rather the cost per cut.  High production rates, long blade life, burr free cuts and the elimination of end finishing are now essential requirements.

Supatec saw blades are provided with staggered chip breaker grooves ground into blades periphery using a borazon grinding wheel.  This grind results on each pair of teeth breaking up the chip into four parts.  These small chips are easily washed away by the coolant stream or spray mist.

When choosing a multi layer coated sawblade there are many essential factors to consider to maximise the benefits of using this type of tool.  For instance, machine capabilities in 4 key-areas can effect efficiency:
Saw motor speed
     If the speed range available is to low, machine output will be reduced.
Insufficient motor power 
     If the torque range is inadequate it will lead to poor blade life.
Hydraulic power
     Insufficient clamping will cause blade damage.
Gear Box
     Backlash in the gear box will damage blades and reduce blade life.

To achieve the lowest costs per cut, all the above need to be considered. 

OTT+HEUGEL are at the forefront of development when it comes to coated, low run out circular saw blades.  A constant research and development program has been relentless in pursuing the most cost efficient saw blades. 

Combined with the tightest quality controls from raw material right through to the finished product, by investing in the most high tech machinery available.  This enables OTT +HEUGEL to manufacture some of the most technically advanced saw blades on the world market.  From their special side grinding process, unique to OTT+HEUGEL, including the most controlled heat treatment process.

Most of the high production machines manufactured today are designed to take advantage of high performance coated saw blades, giving both excellent output and tool life.  Listed are the machines that we have worked with to develop the saw blade and its coatings:
