Boring Machine | Precision Boring Machining Solutions
Housheng Machinery – specializing in precision machining of the inner bores of head tubes, frame tubes, and metal tubing.
With over 40 years of experience in metal pipe processing, we specialize in "double-end precision boring" and "high coaxiality" equipment.
Our boring machines are widely used in industries such as locomotives, bicycles, and auto parts. They can improve the precision, roundness, concentricity, and surface quality of the inner holes after machining, and greatly improve assembly accuracy and product stability.
🏍️ What is a boring machine? Why is boring necessary?
Fine boring is a secondary finishing process performed on the inner bore of pipe fittings or welded parts to achieve the following:
Higher aperture accuracy
Improve roundness and concentricity
Correcting deviations caused by welding deformation
Optimize surface roughness
Ensure that subsequent bearings, pins, and connectors can be assembled accurately.
Especially suitable for:
Head Pipe
Welding the rear frame tube.
Swing Arm Pivot
shock absorber outer tube, faucet tube
🎯 The core value of boring machines in Housheng Machinery
| Advantages | illustrate |
|---|---|
| High-precision coaxiality adjustment capability | Suitable for post-welded components, it can stably control the alignment of the center lines at both ends. |
| High rigidity structural design | The 41 series casting base and 03 series welded base feature stress elimination and heavy-duty slide rails, ensuring no vibration or drift during long-term processing. |
| Optimized jig design capability | Specialized jigs can be developed for complex welded components such as head tubes and frame tubes. |
| High efficiency of dual-end synchronous processing | More consistent precision and shorter processing cycle. |

Customizable optional features
Optional oil mist recovery
Double-end boring means boring holes simultaneously from both sides on the same machine. This design is particularly suitable for machining workpieces such as frame tubes, aluminum brackets, and long metal parts that require boring on both ends. Compared to single-end machining, double-end boring machines significantly reduce working time and ensure symmetrical and highly coaxial hole positions on both sides.
Optional automatic chip removal equipment + powerful water jet
