TPMT及LNEF系列刀片成功应用案例——液压油缸缸筒加工（CN&EN)

液压油缸是液压系统的执行原件，广泛应用在各类机械液压系统中，其主要组成有缸筒、活塞杆、缸盖等。

In these parts,the hydraulic cylinder is often the bottle neck of the production efficiency because of its large inner hole size and high surface finish requirements. In view of this kind of processing problem, GESAC introduced TPMT series insert for rough machining of inner hole and LNEF series insert for finish machining of inner hole.

应用案例1

Application

In case 1, the inner wall of the hydraulic cylinder with a diameter of 280 mm and a hole depth of 2700 mm is roughly machined. The surface roughness of the machined workpiece is required to be within Ra1.6. The rough machining adopts GESAC TPMT insert is used for rough machining, GESAC LNEF insert is used for finish machining, and the insert is equipped with composite cutter body,which can be processed by one-step.The processing scheme provided by GESAC can meet the needs of customers. The tool life is equivalent to the imported brands.

应用案例2

Application

Case 2 is the finish machining about the inner wall of the hydraulic cylinder with 240mm in diameter and 2170mm in hole depth. The surface roughness of the workpiece is required to be less than Ra1.6. Choosing GESAC LNEF series insert,the machining scheme meets the customer’s needs, and the service life of the cutting tools exceeds that of imported brands by 30%.
