For numerical control woodworking lathe, not only improves the working efficiency of the enterprise, while both the machining accuracy, only guarantee the quality of the product can bring good economic benefits for the enterprise. So want you to understand for the machining precision of numerical control woodworking lathe? The detail is below. The machining precision of numerical control woodworking lathe, including several aspects, namely the geometry accuracy, positioning accuracy, static transmission accuracy and precision. First, the geometry precision of numerical control woodworking lathe. Geometric accuracy including shape precision, the geometry precision of position and the relative motion of the geometric accuracy. On the nc lathe machining surface of workpiece shape is depends on the relative motion between cutter and workpiece, and the cutting tool and workpiece is performed by the CNC woodworking lathe is driven directly, so the geometry precision of numerical control lathe is to ensure the machining accuracy of the basic conditions, each type of the geometry precision of numerical control woodworking lathe had its own requirements. Geometric accuracy generally includes: main shaft axial channeling, spindle radial round beating, the perpendicular degree of each coordinate direction, the spindle taper hole axis and tail uranium hole axis, such as height, etc. Second, the positioning accuracy of CNC woodworking lathe. Positioning accuracy index control woodworking lathe movement components from one location to the expected to reach another location of the actual location precision, error between the actual and expected location is called the positioning error. For the rest of dislocation motion components such as cycle, reflect the positioning error for angular displacement error, and the corresponding, its location accuracy is called inversion accuracy. If the movement of the numerical control woodworking lathe parts from one location to another location make repeat positioning, arrive every time the location of the error between the actual location of the maximum, called the repositioning precision of the moving parts. The geometry precision of numerical control woodworking lathe, transmission precision and positioning accuracy, usually without cutting load, and numerical control lathe don't exercise or movement under the condition of low speed detection, so commonly referred to as the static precision CNC lathe. On the static accuracy depends on numerical control woodworking lathe main components, such as main shaft and its bearing, screw nut, the manufacturing precision of gear lathe bed, cabinet, etc and assembling accuracy of them. Positioning accuracy generally includes: repositioning precision linear motion positioning accuracy, linear motion, linear motion precision mechanical origin return, rotary motion positioning accuracy, repositioning precision rotary motion and rotation origin return precision, etc. Third, the static precision of numerical control woodworking lathe. Static accuracy can only to a certain extent, reflect the machining precision of numerical control woodworking lathe, for numerical control woodworking lathe in the actual work condition, there are a number of factors can affect machining precision, such as the elastic deformation of parts, thermal deformation and the vibration of the lathe, the lathe in the moving parts and the working state of movement, the speed of its movement precision is different from low speed detection accuracy, all of which will cause the change of the static precision CNC woodworking lathe, affect the machining precision of workpiece. Precision CNC woodworking lathe work is in motion and the precision of cutting force under the action of the numerical control woodworking lathe in the working status of precision, work precision evaluation by precision processing of specimen. The accuracy is essentially reflect the geometry precision of numerical control woodworking lathe and the positioning accuracy of comprehensive index, is reflected by machining parts. Fourth, the transmission precision of numerical control woodworking lathe. Transmission accuracy refers to the chain within the accuracy of the mutual relation between the connection at both ends. Horizontal CNC lathe, for example, must make sure that the spindle each roll a week, the rest can accurately moving to a lead of the thread processed, otherwise will cause of thread error of workpiece. That is about all the machining accuracy of numerical control woodworking lathe is introduced, the hope can help to you.
