Hole Drilling 
Machine
XDT40 Electric Industrial Line Boring Machine,
Hole Drilling Rod Boring Machine
Hole drilling machine for engineering machinery is a 
portable processing equipment developed for field 
service of engineering machinery, which is mainly used 
in processing of small-scale pipeline inner hole and 
concentric span hole, and widely applied in engineering 
machinery, including excavator, crane, loader, and 
hoist.
Note:
Our machines are 
constantly improving. The actual received accessories 
will be slightly different from the pictures on our web 
pages. The accessories we send can guarantee the normal 
use of boring machine.
Please refer to the 
actual product when you receive the accessories. If you 
have any questions, you can contact us at any time.
Attention
This 
machine is installed by fixed clamping, and uses 
different tool rest according to different diameter 
ranges. Please confirm the diameter of processing hole 
before use to select the appropriate tool rest.
Please read the operation instruction carefully before 
using the machine, and check all the items according to 
packing list to know about operation safety precautions, 
machine performance, and usage specifications.
Features
1.
By 
adopting 110V continuous current motor with 
characteristics of low-speed of revolution and high 
torque, the complete machine can realize stationary 
machining in superior performance.
2.
Feeding 
and processing can realize electrodeless speed 
regulation. Feeding process can be set according to 
demands, and processing can automatically stop after 
reaching the limit switch.
3.
Boring 
bar adopting high-strength alloy and structural steel is 
featured with high hardness, high accuracy, high 
tenacity, good abrasion resistance, etc.
4.
The 
boring bar can be disassembled separately to make 
installation convenient.
5.T
he 
control cabinet is installed below the main engine to be 
beneficial to safety operation.
6.
Electric 
motor controller is equipped with dynamic delay brake 
program to avoid vibration in shutdown.

Equipment Maintenance
In order to ensure the use of hole drilling machine for 
engineering machinery become more convenient and rapid and every 
component can work smoothly, regular cleaning and maintenance 
have to be done to hole drilling machine.
Slushing oil should be painted to boring bar and feed screw 
which are not used very often.
Appropriate grease oil should be added to the feed box every 
half a year.
Spindle box and feed box should be stored by sealing if 
these parts are not used for a long time.
Appropriate grease oil should be added to guide post and 
screw before processing.
Boring bar should be hanged for hoisting to avoid 
deformation when it is not processed.
