Project Background: A leading global gear manufacturer required custom precision gears for its high-performance industrial machinery system—critical to the equipment’s core operational efficiency.

Challenge: The gears demanded tight tolerances (±0.005mm), exceptional durability under extreme operational stress, and seamless integration within a complex mechanical assembly.

Solution: We deployed advanced 5-axis CNC gear machining capabilities, utilizing high-strength alloy steel and aerospace-grade aluminum to optimize the gears’ structural integrity and performance.

Results: The gears were delivered 2 days ahead of the project timeline, fully meeting all tolerance and performance specifications. They enabled 15% improved operational smoothness for the machinery, extending the system’s service lifespan by 20%.

Project Background: A leading automotive OEM engaged LS Manufacturing to supply precision gears for its new fuel-efficient transmission system line—targeting mass production for mid-size passenger vehicles.

Challenge:The gears required a lightweight-yet-robust design (to reduce vehicle curb weight), compliance with IATF 16949 automotive quality standards, and optimized power transmission efficiency to cut fuel consumption.

Solution:We deployed precision CNC gear hobbing + milling, paired with high-strength aluminum alloy (to balance weight and durability), and engineered optimized involute tooth profiles to minimize friction during operation.

Results: The transmission system achieved an 8% reduction in fuel consumption; gear operation noise was cut by 12dB, and the design secured industry recognition for smooth shifting reliability. Our gears supported the OEM’s 50,000-unit annual production target on schedule.

Project Background: A leading 2.5MW wind turbine manufacturer partnered with LS Manufacturing to supply high-precision gears for its main gearbox—critical components for converting turbine rotor torque into grid-compatible electrical power.

Challenge:The gears required structural integrity under continuous 120kN·m load stress, resistance to -40℃~60℃ temperature fluctuations (typical for offshore/continental wind farms), and a 20+ year service life with minimal scheduled maintenance.

Solution: We utilized carburized alloy structural steel (for high fatigue resistance) paired with 5-axis CNC gear grinding (achieving DIN 3-level tolerances), and applied anti-corrosion thermal spray coatings to withstand harsh environmental conditions.

Results: The gearboxes delivered a 2.3% improvement in power generation efficiency; the gears met 25-year design life requirements (exceeding the industry standard 20 years), and maintenance intervals were extended from 12 to 18 months—reducing the turbine operator’s lifecycle costs by 15%.

Project Background: A leading industrial robotics firm engaged LS Manufacturing to supply custom precision gears for its 6-axis collaborative robotic arms—deployed in high-speed electronic component assembly and automotive parts welding (core industrial automation scenarios).

Challenge:The gears required ultra-low backlash (≤0.01mm) for precise motion control, high wear resistance under 1,200+ daily repetitive operations, and compatibility with compact robotic arm enclosures (strict size constraints).

Solution: We applied precision CNC worm grinding + hobbing (achieving AGMA 14-level accuracy), used carburized alloy steel (for high fatigue strength), and added low-friction nitriding surface treatment to meet space and performance demands.

Results: The robotic arms’ repeat positioning accuracy improved by 32% (to ±0.02mm), cycle time per assembly task was reduced by 18%, and gear service life extended to 50,000+ hours—supporting the client’s 2,000-unit annual robotic arm production target.

Project Background: A top-tier agricultural equipment brand partnered with LS Manufacturing to supply robust gears for its new line of 120HP tractors and self-propelled combine harvesters—deployed in large-scale grain planting and harvesting operations.

Challenge:The gears needed to withstand extreme outdoor conditions (mud, dust, -25℃~45℃ temperature fluctuations), sustain continuous 5-ton traction loads (for tractors), and maintain reliability through 800+ hours of seasonal harvesting operations.

Solution:We manufactured gears using high-carbon hardened steel (via CNC hobbing + carburizing treatment) to boost load-bearing capacity, and added anti-corrosion zinc-plated coatings to resist harsh field environments.

Results: Gear durability improved by 40% (extending service life to 1,200+ operating hours); maintenance intervals were extended from 200 to 350 hours, cutting seasonal downtime by 22%. The combine harvesters’ operational efficiency also rose by 12% during peak harvesting periods.
