Fine Pitch Micro Gears

Custom m0.2–m1.0 Fine Pitch Micro Gears for Compact Precision Transmission Systems

MH manufactures custom fine pitch micro gears, also known as small-module micro gears, based on customer drawings, samples, 3D models and technical specifications. MH supports fine pitch micro gear manufacturing across a typical module range of m0.2 to m1.0, depending on gear structure, material, heat treatment, accuracy requirement and inspection method.

 

Representative drawing-based examples include m0.2, m0.3 and m0.5 micro gears for robot actuators, humanoid robot hand mechanisms, aerospace instruments, medical devices, precision motors and compact industrial automation systems. Other modules within the m0.2–m1.0 range can be reviewed according to customer drawings.

What Are Fine Pitch Micro Gears?

Fine pitch micro gears are miniature gears with very small tooth spacing. In metric gear design, they are often described by small module values. For MH's custom micro gear projects, the commonly reviewed fine pitch range is m0.2–m1.0, with representative examples including m0.2, m0.3 and m0.5 gears.

 

These gears are commonly used in compact transmission systems where space is limited but motion accuracy, low backlash, stable meshing and mechanical reliability are important.

 

Compared with larger gears, fine pitch micro gears are more sensitive to burrs, tool wear, heat treatment deformation, runout, pitch error and inspection method. MH reviews each customer drawing before quotation to evaluate manufacturability, material selection, heat treatment risk, tolerance control and inspection requirements.

Fine Pitch Micro Gear Types by Module Range

M0.2–M0.3 Fine Pitch Micro Gears

M0.2–m0.3 fine pitch micro gears are suitable for extremely compact transmission systems, such as humanoid robot fingers, compact actuator modules, miniature gearboxes and precision instruments. Manufacturing focuses on tooth burr control, small tooth profile stability, heat treatment distortion and accurate inspection of fine gear features.

M0.2 Fine Pitch Micro Gears

 

M0.4–M0.6 Fine Pitch Micro Gears

M0.4–m0.6 fine pitch micro gears are often used when the design requires a balance between compact gear size and stronger tooth geometry. This range is suitable for robot actuators, compact gear trains, precision instruments, small motors and industrial automation mechanisms.

M0.5 Fine Pitch Micro Gears

 

M0.7–M1.0 Fine Pitch Precision Gears

M0.7–m1.0 gears are still compact precision gears, but they may provide higher tooth strength and more design flexibility than ultra-small module gears. They can be used in precision instruments, aerospace mechanisms, compact industrial transmission systems and custom gear assemblies.

DIN 5–6 Fine Pitch Micro Gears

For applications requiring higher motion accuracy and better repeatability, fine pitch micro gears may require DIN 5–6 level precision depending on gear structure, material, heat treatment and inspection method. MH evaluates gear accuracy requirements during drawing review and recommends suitable manufacturing and inspection planning.

Manufacturing Challenges of Fine Pitch Micro Gears

Fine pitch micro gears are difficult to manufacture because the gear teeth are small and even minor process variation can affect gear performance. For compact transmission systems, the main manufacturing challenge is not only producing small teeth, but also ensuring stable meshing, low noise, low backlash and repeatable assembly.

 

For ultra-small modules such as m0.2 and m0.3, burr control, tooth profile stability and inspection difficulty are especially important. For medium fine pitch modules such as m0.5 to m1.0, the focus may shift more toward tooth accuracy, heat treatment stability, shaft or bore fit, runout, and batch consistency.

 

MH focuses on the following key points:

  • Tooth burr control after machining
  • Tool wear and tooth profile stability
  • Pitch accuracy and cumulative pitch error
  • Bore or shaft concentricity
  • Gear runout and reference surface control
  • Heat treatment deformation control
  • Surface finish and edge condition
  • Inspection method selection for small tooth features
  • Batch consistency for actuator and gearbox assembly
 

 

Applications of Fine Pitch Micro Gears

Fine Pitch Micro Gears for Robot Actuators

Fine pitch micro gears are widely used in robot actuators where compact size, low backlash, smooth transmission and batch consistency are important. For humanoid robot hands and small joint actuators, m0.2–m0.5 gears can help achieve compact multi-stage transmission designs, while larger fine pitch modules up to m1.0 may be reviewed for higher load requirements.
