Lunan Machine Tool Technology Innovation Project passed the appraisal

Recently, Chenlong Group Shandong Lunan Machine Tool Co., Ltd. held a Shandong Provincial Technological Innovation Project Appraisal and Acceptance Conference undertaken by the company. The expert group identified the TMC21A turning center, PX350-CNC2-T4 CNC spinning machine and XHC715A. The 3 new products of the machining center have a high starting point for research and development, outstanding technical innovations, and all indicators and machine tool performance meet the design requirements. Both have reached the international advanced level of similar products and have passed the appraisal and acceptance.

The TMC21A turning center developed a turning spindle unit with a direct-coupled reluctance encoder and hydraulic brake, which improves the accuracy and response speed of the C-axis index and improves the cutting stability. The hydraulic servo-tailstock and the coaxiality quick-adjustment structure are designed. , Can accurately control the tailstock position and top holding force, quickly adjust the tailstock center and the spindle center of the coaxiality; independent development of the VDI servo turret, tool change speed, high precision. The machine tool can meet the high-speed, high-precision, high-efficiency and automated processing needs of complex parts in high-tech industries such as aerospace, aerospace, defense, military, and shipbuilding.

The PX350-CNC2-T4 CNC spinning machine developed a spin-pressure reversing device. Through hydraulic automatic control, the anti-reel plate was synchronized with the spinning feed and the spinning quality was improved. The top-out spindle of the Neckar key structure was developed. The utility model realizes the function of unloading and mold clamping; adopts a tailstock device integrated with transmission, positioning and guiding, and has simple mechanism, reliable process, convenient operation and high contact rigidity. Mainly to meet the military, air conditioning, fans, automobiles, lamps, musical instruments and other industries for complex surface parts of high-speed, high-efficiency automated processing.

The XHC715A vertical machining center adopts an ultra-wide rectangular four-rail support base with strong rigidity and high bearing capacity. It has independently developed a BT50 high-rigidity spindle unit with high spindle output torque and good low-speed and heavy-load cutting performance. It has developed tool control tool control. The software can realize automatic tool compensation and on-line measurement of parts. The machine tool can realize the clamping of a variety of discs, boards, housings, cams, dies and other complex parts at one time, and completes drilling, milling, boring, expanding, reaming, tapping and other process operations. It is suitable for many varieties, medium and small The coarse and fine processing of batch products is a powerful machining center.
