CALIBER ENGINEERING
Engineering is the control of instability.
Tuning machines are small mechanisms,
yet they define long-term structural stability
under continuous string tension.
Why Instability Happens
Tuning stability is challenged by geometry, friction behavior,
vibration transfer, and long-term structural load.
A precise mechanism must control all four simultaneously.
-
Geometric misalignment over time
-
Micro-vibration during performance
-
Unstable friction behavior
-
Material fatigue under continuous tension
The Structural Platform
Stability is not defined by a single component.
It emerges from a unified structural system.
Three-Part Shaft Architecture
Separating functional zones allows precise alignment control
while preventing tolerance accumulation across the assembly.
One-Body Housing Concept
An integrated housing structure stabilizes center distance
and preserves geometric consistency over time.
Bearing-Based Alignment Strategy
Miniature bearings are positioned to control axial and radial movement,
ensuring stability under continuous string tension.
Friction Architecture & Bushing Logic
Friction is not removed — it is calibrated.
Hand-operated tuning requires controlled resistance, not free rotation.
O-Ring Vibration Management
Distributed damping elements absorb micro-vibration
and contribute to long-term tuning stability during performance.
Transmission of Control
Control is not accidental.
It is transmitted through calibrated mechanical interaction.
Load Path Control
Force from the string is guided
through a defined structural path,
preventing uncontrolled displacement.
Friction Calibration
Friction is not removed — it is engineered.
Controlled resistance stabilizes
hand-operated tuning behavior.
Vibration Dissipation
Micro-vibration is absorbed
before it accumulates into instability,
preserving long-term tuning precision.
Controlled Stability in Practice
Stability is not theoretical.
It is observed in repeatable tuning behavior
under real performance conditions.
Dual Transmission Systems
The structural philosophy remains constant.
The transmission principle differs.
Roller Cam System
A cam-based transmission principle
that transforms rotational input
into controlled axial response.
Load interaction is guided
through geometric modulation
rather than sliding contact.
Worm Gear System
A lead-angle-controlled transmission
that ensures mechanical self-stability
through geometric locking principles.
Rotational control is maintained
through calibrated friction behavior
and defined contact geometry.
