A deep-hole boring and drilling machine rear drill rod sealing oil structure

A deep hole boring and drilling machine oil supplier with an oil-sealing structure at the rear of the drill rod, featuring a rotating clamping component at the front of the oil supplier's housing, a high-pressure oil inlet pipe installed in the middle of the housing, an oil-sealing sleeve at the rear of the housing, a star-shaped seal between the sleeve and housing, a copper spacer sleeve in the center of the sleeve, a horizontal deep hole boring and drilling machine with thermal supply, multiple Aramid fiber packing seals at both ends of the copper spacer sleeve, a horizontal deep hole boring and drilling machine processing manufacturer, with a set of tightening nuts at the rear of the multiple Aramid fiber packing seals, a recommended source of horizontal deep hole boring and drilling machine, where the tightening nuts adjust the compression of the multiple Aramid fiber packing seals. This novel design ensures the sealing of the oil supplier and drill rod, with long-lasting sealant life, reusable after adjustment, and allows for easy and reliable adjustment of the sealant compression with minimal labor intensity, achieving excellent sealing effects.

Deep Hole Boring and Drilling Machine Performance Features:

This machine tool is specifically designed for processing cylindrical deep-hole workpieces, such as spindle holes in machine tools, various mechanical hydraulic, cylinder cylindrical through-holes, blind holes, and stepped holes. The machine not only handles drilling and boring but also roll-forming, utilizing internal exhaust during drilling. The machine bed has high rigidity and good precision retention. The spindle speed range is wide, with the feed system driven by a Japanese Yaskawa AC servo motor, capable of accommodating various deep-hole processing requirements. The oil feeder and workpiece clamping are secured using hydraulic devices, with instrument displays.

To meet the process requirements for deep hole machining, the Chengdu horizontal deep hole boring and drilling machine should possess the following conditions:

Ensure concentricity between the drill rod support (with the drill rod support sleeve), the tool guide sleeve, and the bedhead box spindle as well as the drill rod box spindle.

2) Infinite adjustment of feed movement speed.

3) Sufficient pressure, flow, and clean coolant system.

4) Equipped with safety control indicators, such as the main shaft load (torque) gauge, feed speed gauge, coolant pressure gauge, coolant flow control gauge, filter controller, and coolant temperature monitoring, etc.

5) Tool guiding system. Deep hole drill bits ensure precise bit positioning before drilling into workpieces, with the guide sleeve tightly adjacent to the workpiece end face.

How to analyze the cause of issues in the application of horizontal deep hole boring and drilling machines:

Common issues in the CNC deep hole boring and drilling of horizontal deep hole boring machines for large rotating parts can be analyzed from two main aspects: the workpiece system and the drilling system.

Aspect One: Analysis from the workpiece system perspective, based on the characteristics of deep hole CNC machining, the clamping method for rotating workpieces on the workbench can only be one-clamp-one-drag or two-drag methods. The one-clamp-one-drag method involves the chuck holding one end of the workpiece, both transmitting torque and supporting the weight of the workpiece, while one center support holds the other end. The two-drag method uses two center supports to separately support the left and right ends of the workpiece, with the chuck only used for torque transmission and not supporting the weight of the workpiece.

Method two: For workpieces that are heavy and long, there is an objective deformation due to their own weight, known as deflection. Regardless of the clamping method used, deflection deformation cannot be avoided. Therefore, in actual operation, even with a highly skilled operator, it is impossible to align the workpiece's rotating axis into a straight line. This often leads to phenomena such as the chuck jaws making noise during rotation and the center support roller being damaged.
