Customized Centering Long Axis Machining Of Printer Shaft 316 Stainless Steel

316 Stainless steel Customized centering Long axis machining of printer shaft.

Description

Turning is generally divided into two categories: rough turning and fine turning (including semi-finishing). Rough turning strives to use a large depth of cut and large feed to improve turning efficiency without reducing the cutting speed, but the machining accuracy can only reach IT11, and the surface roughness is Rα20 ~ 10 microns; semi-finishing and finishing Try to use high speed and small feed and depth of cut, the machining accuracy can reach IT10 ~ 7, and the surface roughness is Rα10 ~ 0.16 microns. High-speed precision turning of non-ferrous metal parts with finely ground diamond turning tools on a high-precision lathe can make the machining accuracy reach IT7-5, and the surface roughness is Rα0.04-0.01 microns. This kind of turning is called "mirror turning". If the concave and convex shapes of 0.1 to 0.2 microns are repaired on the cutting edge of the diamond turning tool, the surface of the turning will produce extremely fine and neatly arranged stripes, which will show a brocade-like luster under the action of light diffraction. As a decorative surface, this turning is called "Rainbow Turning".

During turning processing, if the turning tool rotates in the same direction with the workpiece at the corresponding speed ratio (the tool speed is generally several times the workpiece speed) while the workpiece is rotating, the relative motion trajectory of the turning tool and the workpiece can be changed, and the machining Workpieces with polygonal cross-sections (triangular, square, prismatic, hexagonal, etc.). If a periodic radial reciprocating motion is added to the tool holder with respect to each revolution of the workpiece while the turning tool is longitudinally fed, it is possible to machine cams or other surfaces with non-circular cross-sections. On the shovel tooth lathe, the flank face of the teeth of some multi-tooth tools (such as forming milling cutters and gear hob cutters) can be processed according to a similar working principle, which is called "shovel back".
