Recognition by customers and experts
Gear Processing Equipment plays a decisive role in gear accuracy.
Factory open day site，All the guests present agreed that high-precision gears will become the development trend of new energy Vehicle transmission system.。Especially, it has strict standards for gear processing technology.。
The importance of gear accuracy to new energy Vehicles is reflected in many aspects.：
And that transmission efficiency is improve
High precision gear can reduce the friction and energy loss in the transmission process.，So that that transmission efficiency is improve。This is crucial for new energy vehicles that require high efficiency.，Contribute to improving the energy efficiency of the whole vehicle。
Reduce noise and vibration
The tooth profile and pitch of high-precision gears are precisely calculated and optimized，So that that gear are more stable in the meshing proces，Reduce noise and vibration。This will improve the ride comfort of new energy vehicles.NVH（Noise、Vibration、Acoustic roughness）Performance is of great significance。
Ensure safety
The gear transmission system of new energy vehicles needs to withstand the test of high torque and high speed.，High precision gear has high strength and durability.，It can ensure the safe and reliable operation of the transmission system.。
And the service life is prolonged
The manufacturing process and material selection of high-precision gears are strictly controlled.，O that the gear has a longer service life.。This is of great significance for reducing the maintenance cost of new energy vehicles and improving the economy of vehicles.。
To meet the special needs of new energy vehicles
New energy vehicles put forward higher requirements for gear transmission system.，Uch as higher torque density,、Wider operating range, etc.。High precision gears can meet these special needs.，Provide strong support for the development of new energy vehicles。
If the above five criteria are to be met,，
It is also a big challenge for gear processing technology and equipment.。
Make a very small mistake，A thousand miles apart
A workman wants to do his work well.,You must first sharpen your tools.
From gear measurement to cutting, an important closed loop is formed, which plays a key role in the accuracy of gear processing.。
In the development and processing of gear products，Measured by precise gear，We can find and correct the possible errors in the process of processing in time.，Continuous improvement of processing parameters，Until the product reaches the qualified standard.。At the stage of stable production，We control and test the quality of our products.，And adjusting the processing parameters in time according to the measurement result，To ensure that the gear products produced always maintain high precision and high quality.。
The new driving technology in the field of electric vehicles is accelerating iteration.，This brings about a change in the market requirements for the accuracy and process improvement of gear components.。
