It is to support the Gearbox and Arm. It is connected with the Base.
It is on the top of the machine.
It is the rail of the Arm, which can be lifted or lowered by an
elevating motor.
It is to move the spindle.
It is to change the speed of the Spindle. There are three speeds for it.
with three speeds change lever, there are six speeds available on the
machine.
It is to move the head either to right or to left side.
It is to support the Gearbox, connecting with the Column.
It is to start or stop the automatic Knives Feeding.
It is the indicator for the automatic knife feeding. It runs
simultaneously with the feeding knives.
It is the place where drill bit, threading head, drill clamp are
mounted on.
It features a T shape chamfer, which help clamp and position work
piece. In addition, the worktable helps shorten the distance between
the work piece and the drill bit.
It is the gravity center of the machine. It stores the cutting fluids.
When no worktable used, it is used to support the work piece and
applied as a base for processing. It features also a T shape chamfer,
which is very convenient for clamping.
It is used to control the floating of the cutting fluids.
When at boring and automatic feeding needed, the feed rate varies
due to the different material and drilling bit used. It is used to adjust
the feed rate.
It requires the smallest strength and it is the safest way to rotate the
Arm,
All control elements are mounted here.
After feeding knife finished, The spindle will return to its original
point due to the counter weight.
It covers the internal ball screw and hydraulic pump so that the
operator or others can be safely protected.
It is to pump the cutting fluids from the container to lubricate the
drilling or boring.
screw transmission directly, it is very hard to control the elevating
position. Therefore an elevating speed reducer is mounted to easily
control the elevating positions.
It is to elevate up or down the Arm through ball screw.
It is to control the open and close of the switch when the Arm is
clamped hydraulically.
It stores the hydraulic oil.
It indicated the oil pressure gauge. The normal pressure is 38bar。
