Watch Mainplates
Achieving Horological Excellence: Advanced Micromachining for Watch Mainplates
In the world of high-end horology, the watch plate (or mainplate) represents the critical foundation of the mechanical caliber. This component acts as the high-precision stage where every gear and pivot must align with absolute mathematical certainty. Even the slightest deviation in dimensional tolerance or surface integrity can compromise the longevity of the movement.
Mikron Tool develops specialized micromachining technologies engineered specifically for the rigorous standards of high-quality watchmaking. Whether working with traditional alloys or modern sustainable materials, our tools provide the stability and refined finish required by the world’s most prestigious maisons horlogères.
Specialized Engineering for Complex Movement Geometries
Modern calibers are triumphs of miniaturization, featuring dense architectures that leave no room for error. Mikron Tool’s solutions are crafted to master these specific features:
- Intricate Micro-Cavities: High-definition milling of recesses and pockets with sharp corner definition.
- High-Precision Bearing Seats: Delivering perfectly cylindrical holes in a ±1 mm diameter tolerance for jewel settings and oil sinks.
- Squareness in Thin Walls: Maintaining uniform plate thickness, squareness and perpendicularity.
- Burr-Free Edges: Ensuring clean contours on watch plates to facilitate friction-free movement operation.
Overcoming Material Hurdles: From Eco-Brass to Titanium
While Brass is the historical standard for its stability, the industry-wide shift toward Lead-free (Eco) Brass and the use of high-strength alloys like Titanium have introduced new technical obstacles.
Strategic Solutions for Standard and Lead-Free Brass
While standard Brass is known for its excellent machinability, Lead-free Brass can exhibit a "gummy" behavior at the micro-scale, often leading to material adhesion. Lead-free variants lack the natural lubrication of Lead, which increases cutting forces.
- Preventing Material Adhesion: Our tools utilize mirror-polished cutting edges and optimized rake angles to ensure smooth chip flow and prevent built-up edge (BUE).
- Combating Wear in Lead-Free Alloys: We employ wear-resistant carbide grades and low-friction coatings that maintain sharpness despite the higher heat generated by and the lower thermal conductivity of Lead-free materials.
Preventing Chip Recutting with Internal Cooling
To prevent chip recutting, Mikron Tool integrates advanced internal cooling technology into our micro-tools. This system delivers coolant directly to the cutting zone, effectively flushing away heat and chips, which ensures process stability, extends tool life and improves surface quality.
