Note:
The parameters in this table refer to mild steel and other soft materials. For stainless steel, we recommend a 1/10mm (0.1) larger diameter when using an M6 or larger thread. Example: Use 5.5 mm instead of 5.4mm for an M6 thread or 7.4mm instead of 7.3mm for an M8 thread, etc.
Feature
Flowdrilling
A Flowdrill® uses rotational speed and axial force for a local creation of frictional heat. It plastifies metal materials and forms accurate bushings in between seconds:
- with mutiple length of the original material thickness
- chipless, no waste
- in steel, stainless steel, aluminum, brass, copper...
- for all typical material thicknesses>0.5mm
- for high loaded threads from M2 to M20 and up to G1"
- thus replaces welding nuts, rivet nuts
Flowtapping
Flowtapping is also a chipless operation. The thread shape is formed through the whole bush length. Therefore a thread length of minimum 1 x D can normally be achieved. The load of a cold formed thread beats a standard cut thread and effects a positive operating lifetime benefit as well.
5 typical use cases
Applications
Automotive and agriculture
construction, solar and heating industry
Stairs, handrails and fronts
Steel furniture and rehab accessories
Setup instruction
1. Assembling: tool holder and Flowdrill
Dismounting:
- When untighten the nut make sure that the Flowdrill does not just fall out, e.g. use a flannel underneath.
- ATTENTION: do not touch the hot drill with your hands!
2. Preparation: clamping, stop end position, drilling parameters
3. Drilling process
4. Equipment for cold form tapping with FLOWTAP:
5. Parameters table for FLOWDRILL and FLOWTAP
Note:
- The above table information is recommended standard data. The standard requirements may change with different thread sizes and thread length according to different material thicknesses and specific material properties.
- Stainless steel: 15% less rpm for the Flowdrill process based on the optimal rpm and+0.1mm tool diameter for sizes larger M6
- Aluminum and non-ferrous materials: 50% higher rpm for the Flowdrill process based on the optimal RPM.
- All data is based on 2mmmaterial thickness and optimal rpm-power setting. Each additional Millimeter in material thickness requires approx. +1sfor the processing time.
