Initial overview: General advantages and disadvantages of bandsaws and circular saws

Bandsaw

AdvantagesDisadvantages
  • Precise: Bandsaws provide very accurate cutting, especially for complex shapes and tight radii.
  • Versatile: They can cut a variety of materials and thicknesses, making them suitable for various applications.
    Lower thermal output:     The continuous cut generates less heat, which reduces deformation on the workpiece.
  • Slow cutting speed: Compared to circular saws, bandsaws are often slower, which can increase production times.
  • Maintenance required: More time and effort is required to look after them as the blades must be replaced and adjusted regularly.

Circular saw

AdvantagesDisadvantages
  • High cutting speed: Circular saws are faster and are well suited for series production.
  • Easy handling: They are
    often more intuitive to use, which reduces the training time.
  • Less precise when making complex cuts: They are less suitable for precise, delicate cuts or tight radii.
  • Higher thermal output: The
    cut generates more heat, which can lead to deformation or deterioration of material properties.

Bandsaws for versatility and precision

Bandsaws are essential metalworking tools and impress with their flexibility and versatility. They are suitable for cutting a wide range of different metals, from aluminium alloys to high-strength steels and titanium. They enable fast, precise cuts thanks to their endless rotating blade and sharp teeth. If you choose the right toothing and cutting parameters, they can be used for both coarse and fine cuts. Bandsaws are a cost-efficient solution in many industrial manufacturing processes, both for series production and when working on individual workpieces.

Expert tip:The working life of a bandsaw blade is to a large extent dependant on controlled running in. At normal feed rates the sharp teeth of a new blade dig very aggressively into the material. Therefore, the feed rate should be reduced by 50% for the first cuts. After the blade has cut an area of about 300 cm2, the feed rate can be slowly increased to the optimum value.

Attention: Simply get in touch if you need a specific length of saw blade (as from M42). You can, of course, configure the bandsaw blades in line with your specific needs.

When placing an enquiry, please state the bandsaw machine (manufacturer and type), blade dimensions, material and material cross-section. Our application engineers will gladly offer you further technical advice.

Reasons why bandsaws may fail and remedies

  • Fault: Teeth become dull too quickly

    Cause:
    Cutting speed too high, cooling insufficient.

    Remedy:
    Use lower cutting speed, ensure good cooling.

  • Fault: Teeth break off when cutting profiles

    Cause:
    Tooth pitch too coarse / incorrect tooth geometry.
    Cutting pressure too high.
    Workpiece not clamped securely.

    Remedy:
    Adjust the tooth pitch and tooth geometry.
    Reduce the cutting pressure.
    Securely clamp the workpiece.

  • Fault: Teeth break off when cutting solid material

    Cause:
    Tooth pitch too fine.
    Cutting pressure too high.
    Workpiece is not clamped securely.

    Remedy:
    Use larger tooth pitch.
    Reduce cutting pressure or use higher cutting speed if possible.

  • Fault: Blade breaks at the weld seam

    Cause:
    One or both guides are not perpendicular to the vice support.
    One of the two back rollers does not lie against the blade back during the sawing process.
    Blade tension too high or too low.
    Crooked cut.

    Remedy:
    Align the guides using a try square when the blade is tensioned.
    Adjust the blade back guide.
    Observe the machine manufacturer’s instructions to achieve correct blade tension.
    See crooked cut fault.

Wear characteristics on the bandsaw blade and their cause

Wear characteristic: Running marks caused by the blade side guides

Cause:
The blade side guides (usually carbide parts) are worn. One or several wear marks are created regularly. If a wear mark was created only once with only one
bandsaw blade, the cause was a trapped chip (e.g. between the blade and the side guide).

Cracks along the entire blade back edge leading to blade breakage at any point

Cause:
The blade runs against the collar of the drive wheel and/or deflection wheel. Can be checked using the “paper test” – performed by RÖNTGEN-AT. The wheels need to be adjusted. The blade back guide is worn.

Wear characteristic: Pronounced burrs over the entire blade back edge.

Cause:
- All tooth tips are still well formed / sharp:
Blade back guide worn.
- All tooth tips are heavily rounded / worn:
The burr has been created because chips are no longer being produced and the bandsaw blade back edge has therefore been pressed strongly against the blade back guides.
- Cause of rounding:
Tooth pitch is too fine for the material cross-section. Cutting pressure too high, cutting speed too high.

Wear characteristic: Blade split lengthwise.

Cause:
- At least one damping roller is incorrectly positioned or worn.
- A ball bearing (damping roller) is blocked. Corners/edges are rubbing against the blade.
- The blade is split because the bearing is harder than the blade.

Wear characteristic: Tooth tip chipping, tooth breakage

Cause:
Vibrations, chopping and tearing have occurred.
Causes: Tooth pitch too large. Cutting speed
too high. Moving guide arm not adjusted.
Workpiece loose, not sufficiently clamped.

Wear characteristic: Strongly rounded tooth tips

Cause:
- Cutting speed too high.
- Cutting pressure very low.
- Tooth pitch too fine.

Wear characteristic: Cracked weld seam

Cause:
The crack in the blade propagates as a “zigzag”. The blade has obviously been in use for a long time: Tooth tip wear, eroded chip grooves, shiny
running marks evident.
This is an overload breakage. This was caused by worn machine components. Additional wear characteristics can be seen on the blade.
Smooth bursting of the weld seam. All tooth tips are almost as new. The blade only ran for a short time.
This may be a manufacturing defect.

Wear characteristic: Bandsaw blade is heavily deformed

Cause:
Check the position of:

- Drive wheel, deflection wheel
- Damping roller
- Both blade side guides.

Wear characteristic: Problems based on material condition

Cause:
Poor material can cause a hollow, bulbous section, crooked cut, tooth tip breakage.
Hard spots, voids, surface scale, far higher tensile strength than indicated could be the cause.
In general: The machining parameters must be adjusted in line with the material quality and material characteristics.

Bandsaws: An initial selection of bandsaw blades:

Circular saws for efficiency and speed

Circular saws are indispensable in metalworking as they enable fast and precise cuts in metals of different types and thicknesses. Their rotating saw blade mechanism ensures high cutting speeds, which is ideal for coarse cuts and fine work in series production. They are primarily used for work on profiles, tubes, sheet metal, and bar material.
Circular saws are versatile and efficient tools thanks to the wide array of saw blades, which offer different tooth geometries and fittings. They provide very accurate cuts and ensure low material deformation and a long service life, making them an essential tool in modern manufacturing processes.

Sawing instead of grooving: Our recommendations

Circular saw blades, sawing systems from GARANT and Mimatic

In the metalworking industry, circular saw blades with different tooth shapes are available to meet the different requirements for cutting speed, cutting quality and material processing.

Sawing on lathes and milling machines – the advantages:

  • Cutting edge is not permanently engaged, meaning low thermal wear.
  • Chips are effectively removed from the machining zone.
  • Accurate cutting with large diameters.
  • Special machining tasks such as producing slots or notches can be performed very easily.

Sawing on milling machines is particularly suitable for adding thin slots or for parting off finished parts.

Expert tip:

Do not use saw blades for lateral infeed. When cutting off in opposed milling, the chips form a bed in the saw cut that minimises vibrations.
