Detailed Description

As the main part of hydraulic cylinder, mining single prop or hydraulic support, the machining quality of cylinder tube will directly affect the life and reliability of each whole product. The machining quality of cylinder tube is high with general bore roughness spec Ra0.4~0.8μm and high requirement on coaxiality and abrasive resistance. The traditional bore machining process are including boring, reaming, rolling or honing etc. Our manufactured cylinder tube are taking new machining process. The bore roughness after machined is about Ra0.2μm, improved by 2 or 3 levels than other manufacturers. 

Better surface smoothness and sealing performance reduce oil leak problem and improve part quality. 

The surface hardness of bore is increased by 20% comparing general process, which improves wear-resisting performance and makes piston and its sealing part or supporting part move smoothly and ensure the sealing performance and reduce wearing.
