Impeller Machining

5-axis CNC Impeller Machining Service

An impeller is a rotating part of a centrifugal pump that transfers energy from the motor driving the pump to the pumped fluid by moving the fluid from the center of rotation. Usually, the impeller machines’s vanes often have compound curves and are tightly spaced, which makes the process of machining a difficult task. Moreover, the area between the blades is often narrow and deep, a bad combination because it requires long, skinny tools.

Generally, impellers machining from a blank involve CNC turning and CNC milling the excess material from between the blades, semi-finishing the floor and the blades, then finally finishing the floor and blades. With our modern computer-aided manufacturing (CAM) systems, the excess material is milled in precisely monitored layers. Additionally, by keeping the cutter’s centre axis aligned with the cutting forces, side-pressure and vibration can be dramatically reduced, greatly prolonging the tool’s life.

Finishing the vanes of the impeller is the biggest challenge, as they are often thin, distorted and close-spaced. Cutting the vanes in one continuous motion using a tapered-end ballnose cutter will ensure a smooth finish and avoid unwanted vibration.

Types of Impellers machines are:-

Open Impeller

An open impeller has vanes that are mounted directly onto a shaft and are attached to a center hub. The vanes do not have a wall that makes open impellers weaker than closed or semi-closed valves. Open impellers usually clean and repair faster and easier.  For smaller pumps and pumps that treat suspended solids, open impellers are typically used.

Semi-Closed Impeller

There is a back wall of semi-closed impellers which adds power to the impeller. Generally semi-closed impellers are used for liquids or solid products. Reduced performance is a common problem with semi-closed impellers, but a major trade-off is the capacity to move solids.

Closed Impellers

Closed impellers are surrounded by a back and front wall to increase strength. Closed impellers are primarily used in larger pumps and can be used in suspended-solid service applications.

These types of impeller machines are commonly found in clear liquid applications. They don't do well with solids and are difficult to clean if they become clogged. These impellers are fabricated using high grade raw material and technology at par with international standards.
