Horizontal boring machine is the most widely used of boring machines.
It is mainly for hole machining with a boring accuracy of up to IT7.
In addition to expanding the holes that have been cast or machined on the workpiece, the horizontal boring machine can also mill planes, drill, machine the outer circumferences of the end faces and flanges, and cut threads.
Mainly used in single-piece small batch production and repair workshops.
The roundness error of the machined hole is not more than 5 μm, and the surface roughness is Ra 0.63 to 1.25 μm.
The main parameter of the horizontal boring machine is the diameter of the main shaft.
Structure and composition
A boring machine with a horizontal arrangement of the spindle and a vertical movement of the headstock along the front pillar rail.
When using a horizontal boring machine, the tool is mounted on a spindle, mast or flat disk. The required speed and feed can be obtained through the spindle box, and can be moved up and down along the guide rail of the front column.
The workpiece is mounted on the workbench, and the worktable can be moved longitudinally and horizontally with the sliding seat and the upper sliding seat, and can also be rotated around the circular guide rail of the sliding seat to a desired angle to adapt to various processing conditions.
When the mast is long, the tailstock on the rear pillar can be used to support one end to increase stiffness.
In order to process large holes from the workpiece or long box, some horizontal boring machines increase the lateral stroke of the table by about two times. The width of the main guide rail of the bed is increased and the auxiliary rail is used to increase the rigidity of the sliding seat.
The appearance is beautiful and the overall layout is well-coordinated.
The bed, the column and the sliding seat are all rectangular rails with good stability.
The guide rail adopts refrigeration hardening and high wear resistance.
Digital synchronization display, intuitive and accurate, can improve work efficiency and reduce costs.
