Assembly platform identification

The maintenance of the cast iron inspection platform also has the following precautions:

The ability of the cast iron platform material to resist local deformation, especially plastic deformation, indentation or scratching is called hardness. The hardness index of the cast iron platform is usually expressed by Brinell hardness (HB), and the standard is between HB170-240, according to the specific use of the workpiece The hardness generally does not…

We all know that a reasonable choice of processing route can not only improve the cutting efficiency, but also improve the surface machining accuracy of the part. The feed route of the tool on the CNC machining center can be divided into the hole machining feed route and the milling machining feed route. The milling…

Spindle rotation error. The spindle rotation error refers to the variation of the actual rotation axis of the spindle at each instant relative to its average rotation axis. The main reasons for the radial rotation error of the main shaft are: the coaxiality errors of several sections of the main shaft journal, various errors of…

On the basis of ordinary CNC machine tools, the past CNC machine tools mainly developed along the two tracks of precision/ultra-precision CNC machine tools and high-speed processing machine tools. In order to meet the new requirements of workpiece materials, part geometry, precision and surface quality in the CNC machining process, and to improve the competitiveness…

Preventive measures for machine tool casting defects: improve the slag-blocking capacity of the casting system, increase the inner corners of the machine tool castings, there are penetrating or non-penetrating cracks on the machine tool castings (note if they are curved), and the metal skin at the cracks is oxidized. Strictly control the content of S…

Overview The horizontal milling and boring machining center embodies the rapid development of domestic CNC machine tools, marking a new breakthrough in CNC technology in my country. The products range from small-size 300mm worktables to large-size 2500mm worktables, from single worktables to double exchange work; from ordinary to precision, high-speed type plus centers, etc. This…

In recent years, the technology development of horizontal boring and milling machines and floor milling and boring machines at home and abroad has been developing very quickly. It is characterized by the continuous updating of product structure, the endless application of new technologies, the composite of process performance, the continuous improvement of speed and efficiency,…

CNC milling machines can be divided into the following three categories according to the classification method of general milling machines: (1) CNC vertical milling machine, bed type CNC milling machine The axis of the spindle of the CNC vertical milling machine is perpendicular to the horizontal plane. This milling machine accounts for most of the…
