Product Feature And Application

Tangshan Yuexin Machinery Manufacturing Co., Ltd. is equipped with specialized equipment such as CNC deep hole boring machines and honing machines. We employ internal or external chip removal processes to ensure no chip accumulation or scratches during deep hole machining. Simultaneously, we are equipped with an online diameter measurement and straightness detection system to correct errors in real time during machining, avoiding deep hole skew and dimensional deviations. The inner walls of our product holes are honed, resulting in a high surface finish and strong wear resistance. For hydraulic system components, this reduces oil loss and component wear. We also support customized complex deep hole structures such as stepped holes, blind holes, and keyway holes, and can precisely machine according to customer drawings to meet special assembly requirements.

Deep Hole Boring of Workpieces has a wide range of applications. In the hydraulic field, it can be adapted to core components such as hydraulic cylinder bodies, piston rod deep holes, and hydraulic valve sleeves. In the metallurgical field, it is suitable for deep-hole shafts in rolling mill hydraulic systems and deep-hole parts for cooling water pipes. In the construction machinery field, it can be matched with deep-hole parts for hydraulic cylinders and deep-hole shafts in transmission systems of excavators and cranes. With its superior performance, the products widely serve core systems such as hydraulic transmission, cooling, and lubrication in equipment, effectively ensuring efficient and low-loss operation of equipment.

Tangshan Yuexin Machinery's Deep Hole Boring of Workpieces follows a standardized control process throughout the entire process: "Drawing Analysis - Raw Material Selection - Precision Machining - Heat Treatment - Full-Item Inspection." Each step is strictly controlled to ensure product quality. In the pre-processing stage, engineers optimize the machining process and develop segmented or one-time machining plans based on the depth-to-diameter ratio to avoid the risk of deep hole misalignment from the source. In the raw material stage, the pipes are straightened and inspected for flaws, and bent or internally defective materials are rejected to solidify the machining benchmark accuracy.

In the machining stage, CNC deep hole boring machines are used for precise machining according to preset programs, and a high-pressure cooling chip removal system is used to clean chips in a timely manner to avoid scratches on the hole walls. In the finishing stage, multiple processes such as rough boring, fine boring, and honing are carried out to further improve the smoothness and dimensional accuracy of the inner wall of the hole. In the inspection stage, dial indicators, laser diameter gauges, and straightness testers are used to carry out comprehensive inspections, and detailed inspection reports are issued to ensure that each product meets the standard requirements.
