机床的主要特点 Main Characteristics

• 机床床身采用优质铸件浇铸，刚性好，结构稳，变形小;

机床采用床头箱固定在进给滑板上工件进给，车刀及砂轮作往复结构布局，车刀置砂轮前面;

• 工件进给滑板及砂轮工作台滑板采用高刚度十字交叉滚珠导轨;

• 工件进给由伺服电机经联轴器带动高精度滚珠丝杆副来实现，进给和补偿为同一传动链，结构紧凑，精度高;

工件主轴采用箱体主轴结构，主轴轴承采用日本光洋高精度成对轴承，回转精度高，稳定性好，主轴回转采用变频调速;

机床配有防水全封闭罩壳，观察窗保证长期观察清晰，耐油污并保证砂轮破碎后不飞溅伤人;

机床采用后置电器箱和前置回转式操作台以及独立的循环启动按钮。电箱带热交换器，以及确保在高温期间正常运行:

机床可据加工零件设计制作专用夹具:

机床采用西门子808D数控系统，用户如有特殊要求可选用其他控制系统;

 • The machine bed adopts the casting piece with the features of good rigidityand small deformation

 • The headstock is fixed on the feed slide for achieving work feed. The gri.

 • wheel reciprocatian is also used.

 • Work feed guideway and gri. wheel worktable guidaway adopt the crossedroller type.

 • Work feed can be performed by the servo motor through the coupling viahigh-precision ball leadscrew pair.Table reciprocation mavem ent can be achieved by mechanical oscillationwhich its reci speed is adjusted by the freg.-conversion speed reeulator.Cartridge-type work spindle is used, The high-precisian matched spindlebearing is adopted with the features of high rotating accuracy and goodreliability.

 • Super-wide worktable and feed slide are used, thus improving good rigidity.

 • It's totally enclosed with guards to prevent swarfs from splashing.

 • The rear-mounted electrical cabinet and front-mounted control cabinet arealso used, The heat-exchanger in the electrical cabinet is also provided.

 • The special fixture can also be desiened according to the machined workparts
