Breaking-in information

Breaking-in information

Correct breaking-in of saw bands before first-time use has a significant impact on the blade-life! Sharp cutting edges with extremely small edge radii are a prerequisite for optimum cutting and a long blade-life of a new saw band.

The following factors should be observed when breaking-in a band saw blade:

Ensuring that the band saw blade is as free of vibration as possible is decisive for the life span of the machining tool. In particular, a correct run-in is a basic requirement for this. 

  • Determine the correct cutting and feed speed for the cutting material based on the material, dimensions and available band saw blade. WIKUS recommends using ParaMaster to determine the optimum cutting parameters.

Break-in parameters for bimetal and carbide band saw blades for first-time use

Bimetal Band Saw blades

  • approx. 75% of the cutting speed (m/min.) that is suitable for the material and approx. 50% of the feed speed (mm/min.) 
  • break-in time: approx. 300 cm2 or 15 minutes

Carbide Band Saw Blades

  • approx. 75% of the cutting speed (m/min.) that is suitable for the material and approx. 50% of the feed speed (mm/min.)
  • break-in time: approx. 1000 cm2
  • Ensuring that the band saw blade is as free of vibration as possible is decisive for the life span of the machining tool
  • From experience coated band saw blades are less susceptible to vibration. Therefore, the vibration-free sawing can be ended sooner.
     

Incorrect break-ins for band saw blades can lead to broken cutting edges and reduce the life span

Optimally rounded blade thanks to correct break-in

Excessive load due to incorrect break-in leads to micro breaks on the blade

New blades with a very small edge radius

Notes:

New band saw blades tend to vibrate and emit vibration noises. In this case, reduce the cutting speed (m/min.) until no more vibration can be heard.

After breaking-in, slowly increase the cutting speed (m/min.) to the determined value and then gradually increase the feed speed (mm/min.) to the determined value based on the cutting data table, cutting data slide or ParaMaster

When using for the first time, WIKUS always recommends that the

  • Band tension is 250 - 300 N/mm²
  • The oil content of the coolant must be checked with a hand refractometer, and the required oil content should be adjusted if necessary.
  • The recommended oil content of the cooling lubricant can be found in the cutting data slide rule or in Para-Master® 4.0
