Rocker arm type



The spindle box can move on the rocker arm, which can rotate and lift, and the workpiece is fixed and not moving. It is suitable for processing large, heavy, and porous workpieces, and is widely used in mechanical manufacturing.



Deep hole drilling machine


Specialized machine tools that use deep hole drills to drill holes that are much deeper than their diameter (such as deep holes in gun barrels, barrels, and machine tool spindles). In order to facilitate chip removal and avoid the machine tool being too tall, they are generally horizontally arranged, and are often equipped with cooling liquid conveying devices (which input cooling liquid from the inside of the tool to the cutting area) and periodic tool withdrawal and chip removal devices.



Center hole drilling machine


Used for machining center holes at both ends of shaft parts.



Milling and drilling machine


A drilling machine with a workbench that can move vertically and horizontally, and drill shafts arranged vertically, capable of milling.



Horizontal drilling machine


A drilling machine with a horizontally arranged spindle and a vertically movable spindle box. Generally, it has higher processing efficiency than vertical drilling machines and can process multiple surfaces simultaneously.



Editing of operating procedures


1. Before work, it is necessary to comprehensively check whether the operating mechanisms of each part are normal, wipe the rocker arm guide rail clean with fine cotton yarn, and inject oil according to the lubricating oil grade.


2. After the rocker arm and spindle box are locked tightly, operation can only be carried out. 3. There should be no obstacles within the swing range of the rocker arm.



Before drilling, the workbench, workpieces, fixtures, and cutting tools of the drilling machine must be aligned and tightened.



5. Correctly select the spindle speed and feed amount, and do not overload them.



6. When drilling beyond the workbench, the workpiece must be stable.


7. When the machine tool is running and automatically feeding, it is not allowed to change the tightening speed. If the speed is changed, it can only be carried out after the main shaft is completely stopped.


8. Loading and unloading cutting tools and measuring workpieces must be carried out during shutdown. It is not allowed to directly hold the workpiece for drilling or wear gloves for operation.



9. If abnormal noises are found during work, the vehicle must be immediately stopped for inspection and troubleshooting.



Inspection Item Editing



In addition to being inspected according to relevant standards and corresponding standards, the main inspection items of its professional standards include:




1. The flatness of the base workbench.


2. The flatness of the workbench (not included in the rocker drill).


3. Workbench jumping (not available for rocker drills).


4. Radial runout of the spindle cone hole axis.


5. Radial runout of the spindle rotation axis.


6. The verticality of the spindle rotation axis to the working surface of the base.


7. The vertical movement of the spindle sleeve affects the verticality of the working surface of the base.


8. The change in the perpendicularity of the spindle axis to the worktable under the axial force of the spindle.



In addition, the radial drilling machine should also inspect:



1. The rotation of the rocker arm affects the parallelism of the working surface of the base.
