In general, the hydraulic pump can be largely divided into a piston type hydraulic pump and a gear type hydraulic pump. The piston type hydraulic pump is made using the principle of syringe, and the piston installed in the long hole formed in the cylinder block generates hydraulic pressure by linear reciprocating motion. It is a pump. And the piston type hydraulic pump is used for high pressure and high capacity, and it can be used for almost all hydraulic devices because it can precisely control the pressure and discharge amount. The gear pump is a pump that generates hydraulic pressure by the power of a rotating gear. The gear pump is simple to manufacture, and is used in small capacity and low pressure pumps because of its simple structure.
The piston type hydraulic pump is composed of a housing, a head cover, a drive shaft, a cylinder block assembly, and the like. In particular, the cylinder block assembly is a hydraulic pump that generates hydraulic pressure while a piston rotating by the drive shaft acts as a syringe. Is the most important assembly in.

The following describes the procedure for processing the holes into which the piston shoe is inserted into the cutting tool for processing a set plate hole.
Fixing the set plate hole cutting tool to the machining M / C, fixing the set plate machining circular plate to the machining M / C base, inputting the hole size and chamfering degree in the control box, and then operating the machining M / C. Step, the cutting tool for processing the set plate hole is lowered while rotating, and the drill tip drills the hole on the round plate for the set plate processing.After the drilling is completed, the cutting tool for the set plate hole processing is further lowered to boring the hole with the boring tip. After the boring is completed, the cutting tool for the set plate hole processing is further lowered to perform the hole chamfering with the 45 degree inclined machining surface of the tip for chamfering, and the rotating and idle after the cutting tool for the set plate hole processing is raised. While the 45-degree inclined surface of the boring tip is used to process the chamfer, set plate hole Common cutting tool is a single processing set plate hole through the step of restitution is completed. And while repeating the above steps to process the holes into which the piston shoe of the set plate is inserted.
Therefore, the holes into which the piston shoe of the set plate machined by the cutting tool for processing the set plate hole is inserted can improve the chamfering accuracy, and the chamfer does not occur, thereby improving the problem of contact between the piston shoe and the set plate hole edge. have.
In addition, the variable set plate hole cutting tool, which can process various types of holes while adjusting the cutting radius by flowing the body and the tip holder, can improve productivity by processing various kinds of set plates having different hole sizes.
