Due to the shortening of the transmission chain, the CNC gear hobbing machine greatly reduces the transmission error and improves the machining accuracy. However, for high-precision gears, especially gears with large number of teeth, large diameter, long tooth surface, high precision and long machining cycle, they require strict process guarantee during the rolling process, and must control the machining and fixture of the blank. Tools, machine tool adjustments and the environment. Otherwise, even with a CNC hobbing machine, it is difficult to machine a qualified high-precision gear.
1 tooth blank processing
The tooth blank, especially the large diameter blank, is prone to elastic deformation during clamping, which is difficult to compensate for on the hobbing machine, and thus may cause loss of gear meshing accuracy. Since the tooth surface processing often uses the gear hole and the end surface as the reference surface, the accuracy of the tooth blank is mainly required for the dimensional accuracy and shape accuracy of the gear hole, and the positional accuracy of the hole and the end surface (see GB10095-88). For gears with a precision of 6 grades, the size and shape accuracy of the positioning holes are IT6, the roughness is Ra1.6μm, and the radial runout of the gear positioning holes and the end face circular runout tolerance of the indexing circle diameter in the range of 125-400mm do not exceed 0.014 mm. Generally, two processing methods are used to ensure: 1 direct clamping and turning (one-time finishing hole and finishing end of the finishing car): 2 through-axis turning (based on the well-machined hole as the benchmark to complete the turning of the end face and the outer circle). Either way, the blank should be made to meet the specified requirements, and a high-precision hobbing positioning reference surface is required.

LED Grow Lights function by sending an electric current through a semiconductor material.This in turn excites the electrons that create a powerful light from a very small bulb.By using different materials for the semiconductor, it is possible to create LED diodes with different wavelengths of light. This makes them capable of giving your indoor plants exactly what they need for each stage of growth. How those are used will be covered further down.

Our professional full spectrum Grow Light are suitable for all the indoor plants and good for seeding, growth,flowering and fruiting stages of plants, increasing the harvest and Saving energy.
Cautions:
1.Do not use the lights in dripping water or anywhere where they will get wet, water and electricity can be a dangerous mixture
2. The working environment for the light is -20~40 degree celsius,45%RH~90%RH.
3. To protect the light, Plz cut off the power when there is a lightning strike.
4. Don`t touch or move when the light working.
Suggestions:
1.Clean the dust inside every 6 months to ensure the good heat dissipation and long life time.
2.Don`t keep too short distance to the plant canopy to avert leaves bleaching.
3. Highly hang the lamp will weaken the energy and affect the growth cycle of the plants, so the lamp should not be hang too high.
4. While taking care of the plants, please spray the leaves and branches 2-3 times everyday, to ensure the plants do not wrinkle a wither, and have no phenomenon of few fruit, and hard pericarp
