Why does DANIEL make one-click automatic tensioning bone saws?
The 2nd-generation bone saws keep the constant-force benefit of auto tensioning but remove the dependence on blade tolerance and operator feel.
What changed in the 2nd generation
- Internal structure redesigned (not just an added motor): the constant-force tolerance window widened from ±3 mm to ±8 mm (about 3×).
- Blade change simplified to two buttons: press ↓ to release → fit new blade → press ↑ to tension to position.
- Benefits on three fronts: purchasing (common ±8 mm blades), labour (a novice can change blades correctly), product (more stable cutting).
What "one-click auto tensioning" means
The tension force is set by the structure, not by how many times or how long you press the button — the mechanism travels to the design position and stops. After power loss or emergency stop, the tension remains (held by structure, not by current).
FAQ
2nd-gen one-click vs 1st-gen auto tensioning?
Same principle (force from structure). Difference: 1st-gen needs ±3 mm blade tolerance and a handle/knob; 2nd-gen holds constant force within ±8 mm using two buttons.
Will pressing ↑ over-tension the blade?
No. The mechanism stops at the design position automatically; force is set by structure.
If power fails, is the tension still there?
Yes. Tension is held by the structure, not by continuous current.
Does one-click tensioning replace the operator?
No. It simplifies the action, not the judgement — blade seating, pre-tension cleaning and abnormality reading still need a trained operator.
