Zhengzhou professional Henderson mine boring, boring machine processing factory, I plant a load of 20 tons boring 1, load 10 tons Boring Boring 2 Hui, welcome new and old customers to negotiate two seven Boring, cooperation ! Horizontal Boring boring is the most widely used one. It is mainly drilling, boring accuracy up to IT7, in addition to the expansion of the workpiece has been cast or machined hole outside where there is Boring, boring horizontal plane still milling outside, drilling, machining face and flange round, and cut thread, etc., mainly used in single and small batch production and roundness error repair shop, machining hole is not more than 5 microns, and a surface roughness of Ra0.63 ~ 1.25 microns. The main parameters of horizontal boring spindle diameter. Coordinate boring boring mainly for high-precision holes and have the exact coordinates of precision holes. Can be performed with high precision milling. Also used to work crossed and engraved lines, as well as measurements of precision parts such as the model and precision parts. Coordinate boring hole machining coordinate positioning accuracy of up to 0.004 ~ 0.01mm, the surface roughness of the machined surface is less than Ra0.8μm.
