Products Description
CNC machining high strength hydraulic bolt gun housings are precision-machined using CNC technology. They are the core pressure-bearing and transmission components of high-performance hydraulic systems. Designed for extreme operating conditions, they feature extremely high dimensional accuracy, geometric tolerances (such as roundness and cylindricity), and excellent surface finish. Their optimized internal flow paths ensure efficient and smooth flow of hydraulic oil, minimizing pressure loss and turbulence. Precision-machined joints between the gun housing and the bolt achieve extremely low friction and near-zero leakage dynamic sealing, ensuring high response speed, high power density, and long-term operational reliability for the entire hydraulic system. This product is an ideal choice for heavy machinery, industrial equipment, and specialized applications requiring stringent performance and durability.

Material properties

AISI 4340 is a medium-carbon, low-alloy, ultra-high-strength steel in the nickel-chromium-molybdenum system. It is renowned for its exceptional combination of strength, toughness, and fatigue resistance. Through proper heat treatment (particularly quenching and tempering), it can achieve a wide range of mechanical properties, from high strength to high toughness. The machinability of 4340 steel depends on its heat treatment. Generally, rough machining is easiest in the annealed state, while final finishing is usually performed after quenching and tempering (quenching and tempering), when the material hardens and places greater demands on tooling.
