Sawing machine:

horizontal and vertical cold sawing machines with high drive capacity, rigid gear box and opening device for the cutting gap, i.e. Amada, Framag, Lazzari, Linsinger, MFL, Ohler, Wooyoung, Rhobi, Tsune, Wagner, …

Saw blade specifications:

Tooth forms for ferrous metals:

  • chip breaker geometry with alternating 1/3-2/3 chip breaker groove ground into the back of the tooth for good chip formation, enables for high chip thickness, improves wear life at high cutting capacity = preferred tooth form for modern, high- power sawing machines
  • triple chip geometry where the roughing tooth protrudes the finishing cutter for a partition into 3 chips per tooth pair = especially appropriate for very tough material and material with high strength
  • As a common rule all teeth are ground with radial and tangential chamfers
  • Special tooth forms such as HMX, chip deflector, multiple chip geometry, etc. are available for specific demands

Other options:

  • throw-away saw blade
  • SilentCut saw blade with reduced vibration and noise emission
  • ThinCut saw blade with reduced kerf

BLECHER Quality Features

Application oriented selection of blade material

Material selection from a wide range of different alloys and characteristics for application dependent wear life, hardness, stability and toughness, e.g. 51Mn7mod., 75Cr1, 80CrV2, 73WCrMoV2-2, X155CrVMo12-1, S 6-5-2, BLECHER proprietary steel grades BL50, BL55 & BL60/BL80

Consistent documentation

Consistent documentation of all use materials, manufacturing steps and measuring results including from final inspection for each production job

PLC controlled CBN grinding

PLC controlled CBN grinding of carbide tip pocket seats and tooth geometry with oil cooling for lowest heat impact and continuous precision

Individual tooth geometries

Tooth and cutting edge geometry optimized to each customer-specific application

Thermal stress relieve

Blades are thermally stress relieved to eliminate uncontrollable and unwanted residual stresses from the material rolling process which potentially can create performance deviations during use

PLC and pyrometer controlled brazing

PLC and pyrometer controlled automatic brazing for durably reliable welding joints of the carbide tips with no surface hardness increase of the carrier material (saw body)

100% Made in Germany

All materials used for BLECHER saw blades have been made in Germany

Tempering with multiple annealing

Technically matured annealing processes with most advanced furnaces, for hardening and (where appropriate multiple) tempering

Cutting edge rounding

Brushing process to round the cutting edges which avoids premature tip cracking or the need for running in the saw blade

Cool Grinding

In-house developed “cool grinding” technology with most modern PLC controlled grinding machines reduce heat impact during processing and avoid unwanted residual stress

Thermochemical platings

Thermos-chemical platings and hard material coatings available for higher cutting speeds and reduced wear

Optimized hardness/toughness

Cutting edge and tip material with optimized hardness, toughness, composition and edge stability as required by the cutting job and the cutting parameters

Controlled tensioning

Targeted, controlled, reproducible and application oriented blade tensioning guarantees straight cuts with no deviations even across numerous service cycles

In-house development

Saw bodies are all engineered, designed and made in house, this ideally matched with each individual application

Highest environmental standards

Technically matured annealing processes with most advanced furnaces, for hardening and (where appropriate multiple) tempering
