Deep hole boring machine is suitable for machine tool manufacturing, locomotives, ships, coal, hydraulic, power machinery, pneumatic machinery industries such as boring, rolling machining the workpiece roughness of 0.4-0.8μm. This series of deep hole boring situation according to the workpiece machining floor type gantry milling machine, you can choose to work in the form of several of the following: 1, the workpiece rotation, the tool rotating and reciprocating feed motion; 2, rotating the workpiece, the tool does not rotate only reciprocating feed motion ; 3, the workpiece does not rotate, the tool rotating and reciprocating feed motion. Zhengzhou Henderson mine and processing factories specialized boring gantry milling machine, I plant a load of 20 tons boring ordinary gantry milling machine processing, load 10 tons boring 2, welcome new and old customers to negotiate heavy gantry milling machine processing, co-lying type boring: horizontal boring is boring most widely used one. It is mainly drilling, boring accuracy up to IT7, the surface roughness Ra value 1.6-0.8um. ??Main parameters of horizontal boring spindle diameter. Diamond Boring: characteristic form of a small amount of feed and high cutting speed processing, and thus the workpiece with high dimensional precision (IT6), the surface roughness of 0.2 microns.
