SAMPLE Product Details

Industrial equipment Gear Stainless steel ≥ 1.0 g Cost reduction Innovative design Machining

We are able to offer mass production of micro gears with module 0.2, which is out of standard. High geometric tolerance －If the position of the cylindrical edge is set with respect to the of the gear, it is difficult to obtain high reproducibility and accuracy by machining where re-grasping occurs. Since MIM can be integrally molded, high geometric tolerance accuracy can be achieved.

Part name Internal helical gear
Industry Industrial equipment
Category Gear
Material SUS316L
Tolerance Less than ±0.3%
Size Internal diameter φ10mm
Shape characteristic The internal helical gear with the teeth formed till the bottom, as shown in picture, it is impossible to realise with machining since the tool cannot reach the bottom in case the bottom side has a lit. Since our μ-MIM® technology uses mould technology, we can realise shapes that is impossible or very costly to realise by machining. Micro internal helical gear with the teeth formed till the edge with module 0.2 or smaller is possible for serial production with our technology. This shape is almost impossible to realise with other conventional manufacturing methods.
Remarks

Simulation – We are capable of simulating the 3D data of the measurement of manufactured parts and compare with the CAD data, which contributes to shortening of development phase.
Measurement and analysis －even gear manufacturers often do not posses method to measure micro gears that are out of JIS standard. However, at Taisei, we guarantee micro size gear tolerance with state-of-the-art measurement and analysis equipments.
