3. X,Y,Z三軸采用墊片式預(yù)拉伸結(jié)構(gòu),軸向剛性大幅提高且精度更穩(wěn)定
4. 伺服進給系統(tǒng)采用交流伺服電機驅(qū)動與絲杠直接傳動,提高傳動精度。
5. 炮筒式短鼻主軸,整體裝調(diào),維修方便,快捷 。
6.工作臺底部采用三滑塊結(jié)構(gòu),使承載更加均勻且穩(wěn)定可靠。
9. 選用進口滾珠絲桿(THK、NSK、HIWIN、PMI)及大品牌主軸軸承和絲桿軸承(NSK、SKF、FAG);
1.The integral bed ht250-300 high-strength resin sand is used for casting, and after aging treatment, the bed, column, sliding seat and worktable form a C-shape layout, with firm foundation and stable frame.
2. the X, y and Z axes adopt the model of linear rolling guide rail, which has the characteristics of low noise and low wear resistance, sensitive dynamic response and high precision stability, and is suitable for high-precision processing in large quantities;
3. x, y and Z axes adopt pre stretching structure to enhance rigidity and offset thermal deformation
4. the servo feed system is driven by AC servo motor and directly driven by lead screw to improve the transmission accuracy.
5. the barrel type spindle assembly is installed and adjusted as a whole, and the maintenance is convenient and fast.
6. temperature controlled spindle. The spindle sleeve is equipped with a circulating groove outside for constant temperature cooling, so as to keep the spindle temperature rise to the lowest during processing and ensure stable processing accuracy. (optional)
7. the spindle is equipped with a position encoder, which not only realizes the precise determination, but also has the function of rigid tapping.
8. a stable and reliable automatic tool exchange system (ATC) is equipped with a mechanical cam type tool magazine and a manipulator. The action is controlled by the mechanical cam. The tool change is rapid and reliable, and the tool change time is 1.8 seconds.
9. imported ball screw (THK, NSK, HIWIN, PMI) and big brand spindle bearings and screw rod bearings (NSK, SKF, FAG) shall be selected.
