Key points for Instruments And Meter
Precision at the Micro Scale: Zero Burrs, Absolute Accuracy
Specialized micro-module tooling for the instrument and metering industry. Ensuring smooth operation for millions of cycles in brass and alloy components.
The Art of Micro-Motion
Instrumentation gears are central to measurement accuracy. Tiny profiles (module m < 5) must operate with minimal friction; any resistance causes errors. Expertise in micro-machining ensures burr-free solutions for four core precision sectors in this industry.
Metering Counters
Fluid or current movements translate into readings through brass or plastic gears. These components prioritize superior surface finishes and minimal friction coefficients to ensure measurement sensitivity and longevity in residential meters.
Precision Gauges & Indicators
Dial indicators rely on rack and pinion mechanisms to amplify probe movements. Gear accuracy dictates the sensitivity and repeatability of measuring tools, requiring micron-level profile consistency for industrial inspection.
Timing Mechanisms
Industrial timers utilize intricate planetary trains or escapements for sustained, stable operation. Constant torque transmission and wear resistance are mandatory for maintaining synchronized accuracy over extended service lives.
Expert Technical FAQ
Frequently Asked Questions
What is the secret to "Burr-Free" hobbing in brass?
It's all about Edge Sharpness . Standard carbide (0.8µm grain) creates a jagged edge at the microscopic level, which tears the soft brass. Nobeve K-Series uses 0.2µm Ultra-Fine Carbide . This allows us to grind an edge radius of less than 2µm. It cuts the material cleanly like a scalpel, leaving no burrs behind.
Should I use coated or uncoated hobs for brass gears?
For the absolute sharpest edge, we often recommend Uncoated K-Series hobs for brass. Coatings add thickness (2-3µm) and can slightly round the cutting edge. However, for abrasive materials or longer life, a very thin TiCN or TiAlN coating can be applied. We tailor this based on your specific burr tolerance.
Why recommend "Solid Shank" hobs for micro gears?
The biggest problem is solving the interference problem, followed by bore-type hobs (e.g., 6mm bore), there is always a tiny clearance between the hob and the arbor, leading to runout (eccentricity). For a Module 0.2 gear, even 0.01mm runout is a disaster. Solid Shank Hobs are ground integral with the shank, eliminating assembly error and guaranteeing runout below 0.002mm .
Can W-Series Skiving cutters handle stainless steel watch parts?
Yes. W-Series is excellent for stainless steel (like 304/316L) as long as it is in the soft condition (Annealed, HRC < 30) . The high rigidity of the solid carbide prevents the tool from deflecting on small diameter parts. However, high-pressure oil coolant is mandatory to prevent work hardening.
What is the smallest module you can manufacture?
We routinely manufacture K-Series hobs down to Module 0.1 . For skiving cutters (W-Series), the practical limit is around Module 0.15 due to the fragility of the tool teeth. We use specialized grinding machines to ensure profile accuracy even at these microscopic scales.
Do I need a special machine for Micro Skiving?
You need a machine capable of Synchronized Rotation at high speeds. Many modern Swiss-Type Lathes (Citizen, Star, Tsugami) have “Gear Skiving” or “Hobbing” options. These are perfect for producing micro gears in a single setup. Our tools are compatible with standard Swiss tool holders.
How do you clean the parts after cutting to ensure they are meter-ready?
While we supply the tools, we advise that Oil Coolant is essential during cutting to flush away micro-chips. If chips are re-cut, they mar the surface. A low-viscosity cutting oil helps evacuate chips from the fine teeth of the hob and the gear, ensuring a clean surface finish.
Can you make hobs for non-involute profiles like Cycloidal gears?
This mainly because of profiles . We can grind K-Series hobs to any custom profile. You simply provide the DXF geometry or the gear parameters, and we engineer the hob to generate that exact shape.

What Our Client’s Say
A.K.
Plant Manager
“We produce 50,000 water meter movements per day. Even a microscopic burr can cause a meter to jam and fail calibration. Nobeve's K-Series micro hobs with the ultra-fine substrate solved our burr issues completely. We don't even need a deburring station anymore.”
J.M.
Quality Engineer
“For our high-precision dial indicators, the transmission smoothness is everything. We switched to Nobeve's Solid Shank hobs (K-Series) on our Wahli machines. The runout is virtually non-existent, giving us the linearity we need.”
S.L.
Production Supervisor
“Machining micro internal gears for timers was a bottleneck on our shapers. Nobeve's W-Series Skiving cutter on our Star Swiss lathe reduced cycle time. The surface finish is mirror-like.”
