    MK2110B 數控內圓磨床

    機床的主要特點 Main Characteristics

    ?機床床身采用優質鑄件澆鑄,剛性好,結構穩,變形??;
    ?機床采用床頭箱固定在進給滑板上工件進給,砂輪作往復結構布局;
    ?工件進給滑板及砂輪工作臺滑板采用高剛度十字交叉滾柱導軌;
    ?工件進給由伺服電機經聯軸器帶動高精度滾珠絲桿副來實現,進給和補償為同一傳動鏈,結構緊湊,精度高;
    ?砂輪工作臺采用模塊化設計,油缸驅動快趨、快進往復,磨削為砂輪高頻率機械振蕩,振蕩速度變頻調速,提高磨削效率。
    ?工件主軸采用整體套筒式主軸,剛性好,主軸軸承采用高精度成對軸承,回轉精度高,穩定性好,主軸回轉變采用頻無級調速;
    ?采用超寬的工作臺和進給滑板結構,提高機床的整體剛性;
    ?機床配有防水全封閉罩殼,觀察窗保證長期觀察清晰,耐油污并保證砂輪破碎后不飛濺傷人;
    ?機床采用后置電器箱和前置回轉式操作臺以及獨立的循環啟動按鈕。電箱帶熱交換器,以及確保在高溫期間正常運行;
    ?機床可據加工零件設計制作專用夾具;
    ?機床采用日本三菱PLC控制系統、伺服單元及主要電器控制元件,用戶如有特殊要求可選用其他控制系統;
    ?機床磨削冷卻和電主軸冷卻分別采用冷卻系統;電主軸冷卻功能帶斷水保護。
    ?數控內圓磨床MK2110B是模塊系列產品,可據用戶需要制成:
    單軸:數控進給+液壓快趨+機械振蕩往復
    機床型號:MK2110B/1
    雙軸:數控進給+數控往復
    機床型號:MK2110B


    ?The machine bed adopts the casting piece with the features of good rigidity and small deformation.
    ?The headstock is fixed on the feed slide for achieving work feed. The gri. wheel reciprocation is also used.
    ?Work feed guideway and gri. wheel worktable guidaway adopt the crossed roller type.
    ?Work feed can be performed by the servo motor through the coupling via high-precision ball leadscrew pair.
    ?The oil cylinder is used to drive the worktable to achieved gap elimination and rapid advance reciprocation of workpiece.
    ?Table reciprocation movement can be achieved by mechanical oscillation which its reci. speed is adjusted by the freq.-conversion speed regulator.
    ?Cartridge-type work spindle is used. The high-precision matched spindle bearing is adopted with the features of high rotating accuracy and good reliability.
    ?Super-wide worktable and feed slide are used, thus improving good rigidity. It's totally encloscd with guards to prevent swarfs from splashing.
    ?The rear-mounted electrical cabinet and front-mounted control cabinet are also used. The heat-exchanger in the electrical cabinet is also provided.
    ?The special fixture can also be designed according to the machined workparts.
    ?Mitsubishi PLC control system a& servo unit is adopted. Other control system can also be seleted for special order.
    ?The grinding cooling system is adopted. Independent coolant tank can be used for cooling the electric spindle with water-break proiection.
    ?According to requirements of user, this machine can be designed as below: One-axis CNC feed + hyd. gap elm. + mechanical osci. reciprocation Machine model: MK2110B/I
    Two-axis CNC feed + CNC reciprocation Machine model: MK2110B
