The bowl rotation, combined with the robotic movement, creates an exceptionally high pressure between components and grinding medium. This produces perfect and absolutely repeatable finishing results in comparatively low cycle times.
Toyo Aluminum Kabushiki Kaisha has received a patent for a manufacturing method of an aluminum flake pigment, having an average thickness in the range of 0.025 [micro]m and 0.08 [micro]m, and an average particle diameter in the range of 8 [micro]m to 30 [micro]m, the manufacturing method is comprised of a first step of preparing aluminum powder having an average particle diameter in the range of 1 [micro]m to 10 [micro]m by an atomization method, and a second step of grinding the aluminum powder in an organic solvent, wherein the second step is performed using a grinding medium having a diameter in the range of 0.3 mm to 4 mm.
The inplace roll grinder can achieve tolerances to 0.0005" on diameter, concentricity, and straightness, with finishes as fine as 12rms, depending on the grit of the grinding medium. Crowning attachments are optional, and the roll grinder can be fitted for steel, cast iron, rubber, felt, husk, wool, or cotton filled rolls.
Eliminating the need to remove rolls which reduces downtime and avoids distortion by grinding at running temperatures, the RGS in-place portable roll grinder can achieve tolerances to 0.0005" on diameter, concentricity and straightness, with finishes as fine as 12 RMS, depending on the grit of the grinding medium, according to the company.
ViaFlex 120 as the primary grinding medium will exhibit excellent color strength, rheology and pigment stability even in low concentrations, according to the company.
According to the company, using ViaFlex 100 as the primary grinding medium allows energy curable ink formulations to exhibit a greater level of color strength as well as improved rheology and milling ease.
In the wet ambient grinding process, the temperature of the grinding medium, normally water, does not exceed 180-degrees-F.
