Overview:
SKFJX Single-wheel lapping and polishing machines are versatile precision machines designed to produce lapping / polishing flat surfaces in high degree of flatness of and surface finish with absolute uniformity on all types of hard and soft materials.Best to suit high degree of Flatness & Surface Finish.
SKFJX Single-wheel lapping and polishing machines are used for small to large size work pieces. Production of these parts can be achieved from small quantities to high volume production. All machines are equipped with digital control and monitoring electronics.
Working principle:
The conditioning rings or carriers locate in plate and also rotate freely
The parts kept freely inside conditioning rings or carriers with the surface to be lapped mating the Lapping Plate.
The sharp abrasive particles which are continuously fed on the machine plate get impregnated in the Lapping plate and cut the material from the parts surface and creates replica of the plates flatness on to the same.

When seedlings are raised in rapeseed, base fertilizer should be applied, farm manure should be applied more, and seedbeds should be finished. The first is to ensure the area of ​​the seedbed to make it 1:10~6 with Datian. The second is to control the amount of seeds and the seedbed per acre. The sowing rate should not exceed 800 grams; the third is to seedlings, Dingmiao, to prevent partial seedlings too dense; Fourth, we must strengthen management, ensure water and fertilizer supply, and strictly control the pests and diseases.
For high-density rapeseed beds, measures can be taken: early seedlings. 2~3 leaf stage began seedlings, 3 to 4 leaves Dingmiao, to ensure that the spacing of seedlings in about 6 to 8 cm; spray "pacliazole". During the period from 2 to 3 leaves, spraying 100 ppm of paclobutrazol has a significant effect on preventing rapeseed's high-line “line seedlings†and cultivating strong seedlings; proper control of fertilizer and water supply. Especially in the late stage of nursery, nitrogen application and watering should be controlled to prevent the growth of seedlings from growing too high; timely transplanting. Prepare Daejeon early and grab Daejeon in front of rapeseed.
Dilution seedling is the key to rapeseed production
Cultivating strong seedlings is the foundation and key to winning the high yield of rapeseed. The cultivation of seedlings of rapeseed, adherence to thin-seeding, strict control of planting area per unit area, and ensuring the nutrient area per plant of rape seedlings are one of its essential measures. Sowing date, business conditions suitable, seeding per acre seedbed can be about 500 grams.
