M 42 Laser welding Material no. 1.3247 hardness approx. HSS-flat wire 68 - 69 HRC

M 51 Material no. 1.3207 hardness approx. 69 HRC, Blade backer made of alloyed spring steel. with high tungsten- and cobalt content.

Flexible : Perfectly joint : The blade backer of our Bi-Metal Band Saw Blade consists of Both materials are undetachably welded together by a a special alloyed spring steel. Highly flexible at a hardness of special electron or laser beam. about 50 HRC. The ideal basis for long fatigue life and excellent cutting performance. Hard and wear resistant : All advantages : Tooth tips made of hardened HSS-Steel in M 42 or M 51 The high quality Bi-Metal band combines the flexibility quality obtained due to well-balanced hardening and fixed of the spring steel backing with the enormous wear structure resulting in high wear resistance. resistance of the high speed steel. Each tooth tip of the finished band is made of hardened HSS-steel, extremely durable for best performance.

The tooth distance is equally spaced. The number of teeth The tooth distances vary within a group of teeth. The per inch (25,4 mm) denotes the toothing of the saw blade. smallest and the largest tooth pitch denote the variable toothing of the saw blade.

7 Correct tooth pitch – optimum performance. The choice of the right tooth pitch is decisive to achieve the optimum performance. Choose between the standard tooth with constant tooth pitch or the combination tooth with variable tooth pitch. The varibale tooth is recommended for low-vibration sawing in problematic workpieces.

Variable tooth has proven to be the most favourable tooth form. The required tooth pitch is depending on the wall thickness and dimensions of the structurals. The recommendations shown here refer to single cuts. When two or more structurals are cut at the same time, double the wall thickness needs to be considered.

Carbide tipped band saw blades with patented multi Engineered for : chip tooth geometry forcutting high-alloy steels and non- • stainless steel ferrous metals. • heat resistant steels Also coated available IIIIIIIIIIIIII C-TEC for extremely increased feet • cold and hot working steels rates, significantly reduced cutting times and maximized • hardened steel up to 54 HRC blade life. • nickel based alloys • aluminium-silicon alloys For difficult to cut metals such as • copper-nickel alloys stainless steels, tool steels, work • titanium and titanium alloys hardening metals and nickel base alloys. All blade dimensions • exotic, hard to cut alloys and tpi's are available as well in IIIIIIIIIMV (Maximized Value) exe- cution. The wavy ground back edge creates a rocking blade motion for a better tooth penetration, faster cutting rates and increased blade life. Available only in customized welded loops.

Tension measuring device Wrong tension of band can be the reason for crooked cuts or can cause blade breakage. Therefore, the band tension should be checked frequently. Detailed instructions explain how to select and control the right band saw tension.

Refractometer The correct concentration of cooling liquid is important for optimum life time of ARNTZ Band Saw Blades. To check the right concentration of liquid while operating it is ­recommended to use the ARNTZ-Refractometer.

Application toolkit Making sure your blade runs under perfect conditions. Featuring: Tension measuring device, refractometer, tacho- meter, accessories and more.

Break-in procedures : For long blade life. Like all HSS tools, ARNTZ Band Saw Blades should be adhered to a special break-in procedure for extended blade life, less blade changes and best payback of your tool cost. Overload of the razor-sharp tooth tips should be avoided at the start of cutting operation. Aggressive cutting with a new blade will lead to premature tooth breakages. Correct break-in will control the gentle rounding of cutting edges. Bi-Metal Band Saw Blades Starting feed should be half of final feed rate at the recommended cutting speed for the first 46,5 – 77,5 in2 cut surface (see table on page 30). After that, feed rate should be gradually increased for maximum cutting rate. Should vibrations or noises occur at the beginning of the cutting operation, cutting speed should be slightly adjusted. Carbide Tipped Band Saw Blades For break-in procedure during the first 30 minutes we recommend following parameters: Only when the Band Saw Blades are cutting without any vibrations, cutting Material diameter up to 24“ Cutting speed = 100 SFPM speed and feed can be increased step Feed = 0,2“/min. by step to the maximum. The Band Material diameter over 24“ Cutting speed = 80 SFPM Saw Blades are working perfectly when Feed = 0,12“/min. no vibrations will appear.
