5-axis CNC Impeller Machining Service
by Prasad Ugale PRECISION MANUFACTURING SOLUTIONSAn 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.
