Machining centers with more than five axes belong to special special equipment, and they generally process certain types of workpieces in a targeted manner. Briefly introduce the principle of the existence of machine tools with more than five axes: Generally speaking, a five-axis five-linked m...... [Read More]

1. Grinding the outer circle The outer circle of the workpiece is generally ground on an ordinary cylindrical grinder or a universal cylindrical grinder. Cylindrical grinding generally has three methods: longitudinal grinding, horizontal grinding and deep grinding. 1. Longitudinal grinding me...... [Read More]

1. Longitudinal grinding method Longitudinal grinding method is the most commonly used grinding method. During grinding, the worktable is fed longitudinally and the grinding wheel is fed periodically. The grinding allowance of the workpiece must be ground in multiple reciprocating strokes. Fe......

The step surface of the workpiece can be ground by the end surface of the grinding wheel after the outer circle is ground. When grinding, the grinding wheel needs to be withdrawn slightly laterally, and the worktable is turned by hand. After the grinding wheel is in contact with the end surfac...... [Read More]

Application scope and characteristics of inclined bed CNC lathe: 1. Inclined bed CNC lathe is mainly used for multi variety, medium and small batch processing of precision and complex rotary parts. 2. The hydraulic chuck and tailstock can be selected to realize automatic loading and unloading....... [Read More]

CNC milling machine is divided into mechanical part and system part, and the stable and efficient processing of the equipment depends on the normal working cooperation of the two parts. The mechanical part of general machining center is mainly composed of spindle part, feed transmission part a...... [Read More]

1.It is a tool for the operator to exchange information with the numerical control device. 2.Control medium and input/output equipment The control medium is the medium for recording parts processing procedures, and the input/output equipment is the interaction device between the CNC system an......

Reasons for abnormal machining accuracy The causes of abnormal machining accuracy are concealed and difficult to diagnose. Five main reasons are summarized: the feed unit of the machine tool is changed or changed; the zero offset of each axis of the machine tool is abnormal; the axial backlash...... [Read More]

1) Detection and repair of bed rails The V-shaped guide rail of the bed shall meet the following accuracy requirements after inspection: the straightness in the vertical plane ≤0.01mm/m; the straightness in the horizontal plane ≤0.01mm/m; the non-verticality of the sliding saddle guide rail ≤......
