Why are there always defects in the casting process?

Common defects of cast iron parts include: pores, sand sticking, sand inclusion, sand hole, expansion sand, cold barrier, insufficient pouring, shrinkage porosity, shrinkage cavity, lack of meat, sarcoma, etc. Why are there always defects in the lost wax casting process? The gas does not escape in time before the molten metal is crusted, and thus […]

The requirement of CNC machining machine tool for feed motion

The feed motion of a CNC machining machine tool is the direct object of digital control. Regardless of point control or contour control, the final dimensional accuracy (accuracy) and contour accuracy of the workpiece are affected by the transmission accuracy and sensitivity of the feed motion. (Sensitivity) and stability (explanation: stability and stability; no change). […]

Common sense of CNC lathe machining

Repetitive production parts processed by CNC lathes: The preparation time of procedures using CNC grinders occupies a relatively high proportion. For example, process analysis preparation, programming, adjustment and trial cutting of the first part of the part, the total of these comprehensive man-hours is often dozens to hundreds of times the man-hours of a single […]

How to locate the CNC machining center machine?

In the machining process of the CNC machining center, whether the selection of the positioning reference is reasonable determines the quality of the parts, and has a great influence on whether the dimensional accuracy and mutual position accuracy of the parts can be guaranteed and the machining sequence arrangement between the parts. When the workpiece […]
