Abstract: Drilling machine is essential for mechanical manufacturing and repair plant equipment. Drilling machine can accord to the use and structure is divided into vertical drilling machine, Radial drilling machine, Multi-axis drilling machine, etc.
Drilling machine refers primarily with a drill bit in a workpiece processing machining hole machine tool. Usually drill bit is rotating for main movement, the drill bit axial movement as the feed movement. Drilling machine is a simple structure, the processing precision is relatively low, can drill a hole, blind hole, replaces the special cutting tools, can enlarge, counter boring, reaming and tapping, etc processing.
Drilling machine according to the purpose and structure is mainly divided into the following categories.
(1) Bench drill machine: Can be placed on the working platform, spindle vertical arrangement of the small drilling machine.
(2) Vertical drilling machine: Spindle box and working platform placed in the stand column, spindle vertical arrangement of the drilling machine.
(3) Radial drilling machine: Rocker arm can be around the pillar rotary and lift, usually spindle box can move horizontally in rocker arm drilling machine. It is suitable for large and different orientations of hole machining.
(4) Milling drilling machine: Work table can be longitudinal and lateral moves. Drill axis vertical arrangement, able to milling drilling machine.
(5) Deep hole drilling machine: Use special deep hole drill, the workpiece rotation, the drilling of deep hole drilling machine.
(6) Flat end face center hole drilling machine: Cutting shaft end and the processing center drill center hole drilling machine.
(7) Horizontal drilling machine: Spindle horizontal arrangement, headstock vertically movable drilling machine.
(8) Multi-axis drilling machine: Vertical drilling machine, there is a plurality of available drill spindle, and can be adjusted flexibly.
