Introduction NiO is an important inorganic material which is applied in catalyst, battery electrode, gas sensor, magnetic material and electronic material industry [1-4].
As we know, the property and quality of nano-materials depends very much on their particle size and morphology.

Introduction Machine tool geometric error, thermal error and the error due to cutting force is key factors which affect the machining accuracy of NC machine tool [1], account for about 80% of the total machining error, due to the automobile cover parts die material is die steel Cr12MoV and 7CrSiMnMoV, such as hardness after quenching can reach HRC50-65, belongs to typical high strength, high hardness materials, so it is easy that cutting force-induced tool deflections cause surface error.

First, the materials for WO3/Pd sol, the devices and the detail steps of the sol preparation were introduced.
Experiments show that material ratios, equipments and procedures have to be cautious.
For WO3/Pd sol, main reagents and materials include: tungsten powder (99.8%), hydrogen peroxide (30%), ethanol, acetone, platinum wire, chloroplatinic acid, palladium chloride, silver nitrate and sodium citrate.
