Welded Hydraulic Cylinder is a type of hydraulic cylinder that is constructed by welding the end caps and cylinder barrel together to create a single, solid unit. The cylinder barrel is typically made of a high-strength steel tube, while the end caps are usually made of forged steel or cast iron. The piston, piston rod, and other internal components are then installed inside the cylinder barrel.
Welded hydraulic cylinders are popular due to their compact size, strength, and durability. The welded construction creates a rigid and durable cylinder that is less likely to leak or fail under heavy loads or harsh operating conditions. Welded hydraulic cylinders are also more compact than other types of cylinders, as the welded design eliminates the need for external tie rods or other components that can add to the overall size and weight of the cylinder. This makes welded hydraulic cylinders ideal for use in tight spaces or applications where weight is a concern.

To compensate for the tool position caused by the radius r of the tool tip when turning the surface. When tool position compensation is performed in the Z direction and X direction at the same time, the actual blade contact point with the workpiece moves to the tool tip set point P during programming. The compensation amount of r can be calculated by the following formula: In this case, the base point coordinate is the compensation amount (Dz and DX) of the base point coordinate (Z and X) of the workpiece contour plus the radius of the tip arc, which solves the problem of no tip radius compensation.
In NC machining, because the tool tip has a circular arc, the contour of the workpiece is formed by the tool motion envelope. Therefore, the motion path of the tool point is not coincident with the contour of the workpiece. In the full-function CNC system, its tool compensation command can be applied. According to the workpiece contour size, it is convenient to program and process. In the economical numerical control system, the trajectory of the tool location can be calculated according to the workpiece contour size, tool, etc., and programming can be done according to the method of local compensation.
Analysis of Calculating Method of Bias of Knife Cutter Point on CNC Lathe
In order to facilitate the knife, in the numerical control turning process, the tool is usually set with the imaginary tip P point. If there is no tip radius compensation, undercut will occur when turning cones or arcs. When the part requires high accuracy and has a cone or arc, the solution is: calculate the center of the arc radius of the tool nose, and then click this to calculate the local compensation.
