    • Dividing table of taper sleeve machine tool

      The indexing table is in accordance with the instructions of the CNC system. When indexing is needed, the table and the angle specified by the workpiece rotation can sometimes be manually indexed. The indexing table can only complete indexing motion but not circular feed motion, and its indexing motion can only complete certain degrees of rotation such as 90, 60 or 45, so as to change the position of the workpiece relative to the spindle, so that the workpiece can be installed at one time to process multiple surfaces.<了解详情>

    • Dust-proof sealing rings commonly used in ball screw pairs of taper sleeve machine tools

      The sealing ring is mounted at both ends of the ball nut. Contact elastic seal ring pump is made of oil-resistant rubber or nylon and other materials. Its inner hole is made into a shape matching with screw thread raceway. Contact seal ring has good dust-proof effect, but because of contact pressure, friction moment increases. The non-contact sealing ring is made of polyvinyl chloride and other plastics. Its inner hole shape is opposite to the screw thread raceway and has slight clearance. The non-contact sealing ring is also called labyrinth sealing ring.<了解详情>

    • 任丘市海华机械配件有限公司Maximum Fast Moving Speed and Feed Speed in Cone Sleeve Machining

      The maximum fast moving speed refers to the highest moving speed of the feed shaft in the non-processing state, and the highest moving speed refers to the highest moving speed of the feed shaft in the processing state. They are also the main factors affecting the quality of parts processing, production efficiency and tool life. These two performance indicators are limited by such factors as operation speed of NC device, dynamic characteristics of machine tool and stiffness of process system.<了解详情>

    • How to work efficiently in taper sleeve processing and production?

      In order to reduce the auxiliary time of machine tool and improve the efficiency of machine tool, a series of measures have been taken, such as shortening the tool changing time, the shortest tool changing time of NC machine tool is 0.5s now; adopting new tool library and tool changing manipulator to make the action of selecting tool coincide with the time of maneuvering, which is fast and reliable; adopting various forms of exchange workbench to make the time of loading and unloading workpiece coincide with the time of maneuvering, and at the same time shorten the time. Workbench switching time; widely used off-line programming, graphics simulation and other technologies to achieve background input modification editing procedures, foreground processing to shorten the new processing procedures on-line debugging time; the use of quick change fixtures, tool devices and the realization of rapid determination of the origin of the workpiece, to shorten the adjustment time of machine tools and tools.<了解详情>

    • Principle of Concentration of Processing Processes for Cone Sleeve

      Machining center machine tool makes the process concentrated on one machine tool, reduces the positioning error caused by process dispersion and multiple clamping of workpieces, improves the processing accuracy, reduces the number and area of machine tools, reduces the assistant time between processes, and effectively improves the productivity of NC machine tools and the economic benefits of NC processing. Therefore, it is the development trend of NC machine tools to achieve high concentration of process.<了解详情>
