NEW TYPE OF CYCLOIDAL-PIN GEAR SPEED REDUCER
Recently, we have introduced a new type of cycloidal-pin gear speed reducer to our product lineup.
We are responsible for the production and assembly of the reducer. For this product, the cycloidal gears undergo a heat treatment process to achieve a hardness of HRC60 while still maintaining precision within +/-0.01mm. Through meticulous attention to every detail in production, rigorous inspections, and skilled assembly, we have successfully met the exacting demands of our customers.
 The cycloidal gear, which has undergone HRC60 heat treatment, is illustrated in the details provided in the "READ MORE" section. For those seeking more information, please do not hesitate to contact us. We are dedicated to providing you with exceptional service.

A MOLD FOR CONNECTORS IN THE REALM OF NEW ELECTRIC VEHICLES
A MOLD FOR CONNECTORS IN THE REALM OF NEW ELECTRIC VEHICLES
The mold presents several challenges,Mold Complexity
1: The steel components responsible for sliding and scraping possess a lengthy and slender form, measuring just 1.5mm in width.  Achieving a machining precision of 0/-0.005mm in this region is imperative to prevent collision risks during production.  Mold Complexity
2: All the square holes within the product are ground with precision ranging from 0.003mm to 0.005mm.  The smallest square hole measures 0.65mm by 0.65mm, presenting substantial machining difficulty and demanding exceptional precision.  Eventually, we have successfully met the exacting demands of our customers.

THIS IS A CRUCIAL COMPONENT WITHIN A WELL-KNOWN BRAND'S HAMMER DRILL.
The product is characterized by complexity in its structure, reflecting its advanced design.
It places high importance on precise positional accuracy, necessitating concentricity levels below 0.01.  The product maintains rigorous dimensional standards;  inner holes and outer diameters are closely regulated to meet H7 tolerances, maintaining this precision even when inner holes are magnified to five times their diameter.  Notably, the product upholds demanding roughness criteria, with a maximum limit of Ra0.4.  We achieved a zero-defect accomplishment when the customer requested high-volume production of this product.  Additional detailed images can be found in "READ MORE."  For further processing information.  Please feel free to contact us.  We're devoted to delivering dedicated service to you.
