铣床结构分类
(1)台式铣床：小型的用于铣削仪器、仪表等小型零件的铣床。
(2)悬臂式铣床：铣头装在悬臂上的铣床，床身水平布置，悬臂通常可沿床身一侧立柱导轨作垂直移动，铣头沿悬臂导轨移动。
(3)滑枕式铣床：主轴装在滑枕上的铣床，床身水平布置，滑枕可沿滑鞍导轨作横向移动，滑鞍可沿立柱导轨作垂直移动。
(4)龙门式铣床：床身水平布置，其两侧的立柱和连接梁构成门架的铣床。铣头装在横梁和立柱上，可沿其导轨移动。通常横梁可沿立柱导轨垂向移动，工作台可沿床身导轨纵向移动。用于大件加工。
(5)平面铣床：用于铣削平面和成型面的铣床，床身水平布置，通常工作台沿床身导轨纵向移动，主轴可轴向移动。它结构简单，生产效率高。
(6)仿形铣床：对工件进行仿形加工的铣床。一般用于加工复杂形状工件。
(7)升降台铣床：具有可沿床身导轨垂直移动的升降台的铣床，通常安装在升降台上的工作台和滑鞍可分别作纵向、横向移动。
(8)摇臂铣床：摇臂装在床身顶部，铣头装在摇臂一端，摇臂可在水平面内回转和移动，铣头能在摇臂的端面上回转一定角度的铣床。
(9)床身式铣床：工作台不能升降，可沿床身导轨作纵向移动，铣头或立柱可作垂直移动的铣床。
(10)专用铣床：例如工具铣床：用于铣削工具模具的铣床，加工精度高，加工形状复杂。
Classification of milling machine structure
(1) Table type milling machine: small milling machine used for milling small parts such as instruments and meters.
(2) Cantilever type milling machine: milling machine with milling head installed on cantilever. The bed is horizontally arranged. The cantilever can normally move vertically along the column guide rail on one side of the bed, and the milling head moves along the cantilever guide rail.
(3) Ram type milling machine: the milling machine with the main shaft installed on the ram. The bed is arranged horizontally. The ram can move horizontally along the saddle guide rail, and the saddle can move vertically along the column guide rail.
(4) Gantry type milling machine: the machine bed is horizontally arranged, and the columns and connecting beams on both sides constitute the gantry. The milling head is installed on the beam and column and can move along its guide rail. Generally, the beam can move vertically along the column guide rail, and the working table can move longitudinally along the bed guide rail. For large parts processing.
(5) Plane milling machine: it is used for milling plane and forming surface. The bed is arranged horizontally. Generally, the worktable moves longitudinally along the guide rail of the bed, and the spindle can move axially. It has simple structure and high production efficiency.
(6) Profiling milling machine: the milling machine for copying the workpiece. It is generally used to process complex shape workpieces.
(7) Lifting table milling machine: a milling machine with a lifting table that can move vertically along the bed guide rail. The worktable and sliding saddle installed on the lifting table can move longitudinally and horizontally respectively.
(8) Rocker milling machine: the rocker arm is installed on the top of the bed, and the milling head is installed at one end of the rocker arm. The rocker arm can rotate and move in the horizontal plane, and the milling head can rotate at a certain angle on the end face of the rocker arm.
(9) Bed type milling machine: the worktable can’t move up and down, it can move longitudinally along the bed guide rail, and the milling head or column can move vertically.
(10) Special milling machine: such as tool milling machine: milling machine for milling tool mould, with high machining precision and complex processing shape.
