Read MoreWhen near-dry milling with MQL, the tool's cutting edge works inside a mist formed from oil and compressed air, which is sprayed directly into the cutting zone. Depending on the design of a machine tool and milling cutter, the mist is delivered externally or internally through the cutter. The main function of MQL is to lubricate the cutting edge.

Read MoreRoland DG's DWX-50 5 Axis Dental (dry) Milling Machine and our new DWX-4W Wet Dental Mill offer a more flexible solution. Whatever your opinion is of the aesthetic or production values of glass ceramic vs. zirconia, the current restoration market is dictating a need for both options and labs should be responsive to this.
Read MoreWet Milling. For a faster and more consistent drying process downstream, manufacturers may want to reduce the particle size of material. This increases the surface area of the product, enabling it to dry quicker before downstream processes. Through wet milling, lumpy and uneven powder can be reduced to a uniform particle size.
Read MoreDry Vs. Wet Etching . Ion Beam Milling (Dry Etching) is a process where ions are driven into the part being etched at a high rate of speed. When the ions make contact, metal particles are then knocked off. Ion Beam Milling is not selective--it etches everything, but at different rates.
Read MoreIn a wet mill, on the other hand, particles are dispersed in a liquid slurry and pumped through a grinding chamber. The particles ride along in the liquid and are crushed among the grinding media. Dry grinding, as in a jet mill, uses a single pass process; material enters the mill, passes through, and is expelled, reduced in size.

Read MoreKND recommends Dry-milling with a carbide bur. Milling is done by using a Carbide bur under both Dry and Wet conditions. Grinding is done with a Diamond bur under Wet conditions. If the customer selects the Milling option, and the machine is a properly equiped Dry-milling units, the CEREC machine
Read MoreAdditionally, while dry milling is usually carried out in six-roll mills, wet milling can be successfully performed using two-roll mills. The only problems presented by wet milling occur during the sparging of the malt with water. Overall, however, wet milling has more advantages than disadvantages in com-parison to dry milling21.
