Rotor Balancing Services For Medical Research Equipment

Our capabilities include rotor balancing of small to medium sized components like shaft stubs, and even small equipment weighing only a few grams. Especially in the medical research field, rotating parts are so tiny that they have to be balanced against their weight. And it becomes almost impossible to belt drive them.

Thus, these parts need precision machining to cancel the counter effect of weights and avoid vibrations. Our machinists treat them as fixture units in the balancer. For example, in a blower, balances and force corrections are done by pricking the corners of impeller blades.

Rotor Balancing Services For Aerospace Industry Equipment

For the aerospace industry, weight and vibrations are critical to ensure safety. At Macfab, we employ high-speed electronic rotors for obtaining correct results.


Benefits Of Balancing And Vibration Testing

Unbalance exists in a rotor when the mass centre axis is different to its running centre axis. Practically all newly machined parts are non-symmetrical due to blow holes in castings, uneven number and position of bolt holes, parts fitted off-centre, machined diameters eccentric to the bearing locations etc.

An unbalanced rotor, when rotating, wants to revolve around its mass centre axis. Because the bearings restrict this movement, the centrifugal force, due to the unbalance, causes the rotor to vibrate. This vibration causes wear to the bearings, creates unnecessary noise, and, in extreme cases disintegration of the rotor itself can be experienced. It is therefore necessary to reduce the unbalance to an acceptable limit.

Increased Part Life

An unbalanced rotor leads to uneven dynamic force resulting in high impact force and increased wear and tear of the rotor. Reducing the degree of unbalanced rotor con help control the problems and increase part life.

Higher Uptime And Productivity

A balanced rotor/shaft will have fewer vibrations and hence fewer misalignments. This means you would require less downtime for maintenance resulting in better productivity.

Lower Operating Cost

High vibrations tend to loosen fasteners making the complete machine structure less stable, requiring frequent replacement. This adds to the overall project cost. Analyzing vibrations and rectifying the dynamic load can bring down the costs.


Types Of Rotor Unbalance, Their Correction And Vibrations

Static Unbalance

Static unbalance happens where the mass axis is displaced only parallel to the shaft axis. The unbalance is corrected only in one axial plane.

Couple Unbalance

Couple unbalance is where the mass axis intersects the running axis. For example: a disk that has swash run out with no static unbalance. The unbalance is usually corrected in two planes.

Dynamic Unbalance

When the mass axis is not coincidental with the rotational axis, it is called dynamic unbalance. This unbalance is usually a combination of static and couple unbalance and is corrected in two planes.
