Metal Bandsaw Blades
We produce three versions of metal bandsaw blades for you. The "carbon" grade for workshops, the bi-metal grade for workshops and manufacturing purposes as well as the hard metal variant for special applications.
True to the motto:
We deliver the metal bandsaw blades that will lead to the optimal sawing result in accordance with your specific requirements.
Trust in our machining technology, if you wish to cut materials in an optimal manner
In order to meet every one of your requirements, we have provided our material grades with the necessary range of tooth types:
This tooth geometry is provided with our No. 20 GUHEMA Kristall, No. 22 GUHEMA Kristall plus and No. 35 GUHEMA Bi-Co-lastic grades. This geometry is ideal for universal, general purpose use.
This tooth geometry is available for our No. 20 GUHEMA Kristall, No. 22 GUHEMA Kristall plus and No. 35 GUHEMA Bi-Co-lastic grades. The areas of application of this geometry are the austenitic and stainless steels.
The variable toothing is provided with the No. 35V GUHEMA Bi-Co-lastic grade. This V-toothing leads to an especially low-vibration cut and is suitable for bundle cutting as well as for solid materials. As the area of application for the metal bandsaw blades with V-toothing becomes significantly larger, the band changing times that would otherwise be necessary are prevented and thus the downtimes of the machine decrease. The reduced noise level at the workplace is a side effect of the variable toothing that is often praised by the workforce.
The VP-toothing is provided with the No. 35VP GUHEMA Bi-Co-lastic and No. 36VP GUHEMA Bi-Co-lastic plus grades. This variable positive toothing achieves maximum machining performance with a long tool life. Machining technology at the highest level
The variable special tooth form is provided with the No. 33VP-D GUHEMA Bi-Co-lastic and No. 34VP-D GUHEMA Bi-Co-lastic grades.
The tooth design with the extra-strong tooth backing has been specifically developed for bundle cutting and profile as well as girder cutting. The positive cutting angle contributes to optimal chip formation and thus a clean cutting path.
The carbide grit coated cutter is provided as a continuous variant with No. 40 GUHEMA HM-Granulate and as an intermittent variant with No. 41 GUHEMA HM-Granulate. This toothing succeeds where conventional saw teeth fail.
The positive toothing is provided with the No. 44p GUHEMA HM-Teeth and 45P GUHEMA HM-Teeth grades. This toothing has been developed to bridge the transition to the hard metal class. Abrasive workpieces as well as silted cast iron workpieces can be separated with this toothing.
The variable positive toothing is provided with the No. 46VP GUHEMA HM-Teeth grade. The variable tooth sequence is constructed with ground hard metal teeth that are provided with pre- and finishing cutters. This toothing achieves the maximum cutting speed and maximum service life.
The variable negative toothing is provided with the No. 47VN GUHEMA HM-Teeth grade. The negatively ground hard metal teeth allow for the machining of extremely hard workpieces. This special toothing is, for example, used for surface hardened shafts.
Which bandsaw blade width do I need?
Generally speaking, you should choose the maximum bandwidth that is permissible for your machine. High stability of the band with high feed forces is the advantage of this. When using metal bandsaw blades for contour cuts, the width of the bandsaw blade depends on the smallest radius to be cut. The following graphic provides a visual aid when determining the sawblade width.
Our recommendations for a long service life right from the start
When using GUHEMA metal bandsaw blades, we recommend only a few, but very important rules concerning the workpiece, machine and bandsaw blade in order to achieve optimal cutting results:
Running in process of bi-metal bandsaw blades
Select the recommended cutting speed and reduce the feed speed to 50% of the recommended feed during the run-in period.
- In case of large cross-sections, keep this for 15 minutes.
- In case of small workpiece dimensions, you should machine around 300 cm2 with this setting.
Reduce the cutting speed in case of vibration noise or machine vibrations.
After the run-in process, slowly increase the feed speed to the recommended cutting parameter.
The running-in of the bandsaw blade leads to an optimal cutting edge formation, where the edge radii are reduced to a minimum, which in turn causes the tooth geometry to be formed optimally.
Running-in of hard metal bandsaw blades
For this purpose, set the cutting speed to 75% of the recommended speed and reduce the feed speed by approx. 50% of the recommended feed.
- In case of large cross-sections, keep this for 15 minutes.
- In case of small workpiece dimensions, you should machine around 300 cm2 with this setting.
Avoid vibration noises or machine noises at all costs by further reducing the cutting speed.
After the run-in process, slowly increase the cutting speed to the recommended speed. Now increase the feed speed to the recommended parameter.
The running-in of the bandsaw blade leads to an optimal cutting edge formation, where the edge radii are reduced to a minimum, which in turn causes the tooth geometry to be formed optimally.
