Mechanical drilling
Drilling machine refers to a machine tool that mainly uses a drill bit to machine a hole in a workpiece. Usually the drill bit rotates for the main motion and the drill bit moves axially for the feed motion. The drilling machine has a simple structure and relatively low machining precision. It can drill through holes and blind holes, replace special tools, expand, boring, reaming or tapping.
Drilling machines can be divided into the following types:
(1) Bench Drilling Machine: A small drilling machine that can be placed on the workbench and the main shaft is vertically arranged.
(2) Vertical drilling machine: the headstock and the worktable are placed on the column, and the drilling machine is arranged vertically.
(3) Radial Drilling Machine: The rocker arm can be rotated and lifted around the column. Usually, the headstock can be used as a horizontally moving drilling machine on the rocker arm. It is suitable for machining large and different azimuth holes.
(4) Milling and drilling machine: The working table can be moved vertically and horizontally, the drill shaft is vertically arranged, and the drilling machine can be milled.
(5) Deep hole drilling machine: use a special deep hole drill bit to rotate the workpiece and drill a deep hole drilling machine.
(6) Flat-end center hole drilling machine: cutting shaft end face and central hole drilling machine processed by center drilling.
(7) Horizontal drilling machine: the drilling machine is arranged horizontally and the headstock can be moved vertically.
