11000 pound fluid friction dynamometer rotor resting in our soft bearing high speed balancer. The rotor will be balanced at 1500 rpm. Soft bearing balancers are particularly suited for high precision balancing as they do not have structural resonance problems. This soft bearing machine can easily balance large rotors below ISO g1.0.
Large Permanent Magnet Motor / Generator Rotor being loaded into our custom balancing machine. Under the blue coating there are hundreds of high power neodymium magnets. Permanent Magnet Rotors can create extreme inductive forces in the balancing machine support structure and confuse balancing readouts. HI-TEK has the knowledge how to prevent electromotive forces from damaging the machine and affecting its accuracy.
In our shop we have many types of machines to help us work on equipment of all sizes as well as individual machine parts. Our shop includes a cylindrical grinder, which is a machine that is used to help shape the outside of an object with a specific technique. The concept for cylindrical grinders was first introduced in the 1830s and improved upon for many decades after. To qualify as cylindrical grinding, there are four essential conditions that must be met Continue reading “What is cylindrical grinding?”
Sometimes it’s easy to forget that the industry-specific language that we use every day can be used in a different context to mean something else entirely. Terms like “broaching” don’t really provide any extra details to help you figure out what it means. We have a broaching press (18” travel ) in our shop, but if you aren’t familiar with the machine, you probably don’t know how we can use it to help you.
Broaching is a type of machining that uses a tool called a broach to remove material from metal objects. The broach has many teeth that can come in several different shapes. The two main types of broaching are linear and rotary. These names refer to the directions in which the broach is moved against the metal material. Most broaching presses are linear. Rotary broaches are used in lathes or screw machines. Broaching is a technique that offers great precision, so it’s often used to make unusually shaped pieces.

Here at Hi-Tek Balancing, we work with quite a few different types of machines regularly. Each of our machines fulfills a slightly different purpose, enabling us to create and repair complicated machine parts for many types of equipment. This month we’d like to explain a little about our knee mills. A knee mill is a milling machine that has an x-y table that can be adjusted vertically up and down the column. They are also sometimes referred to as a knee-and-column mill. Most other types of milling machines have x-y tables that are stationary instead. As you can imagine, this gives us more flexibility in the shop. Continue reading “What is a Knee Mill?”
Whip balancing is an important part of maintenance for machines that have rotors. Resonant frequency is another name for whip. The resonant frequency is a measure of the speed, in cycles per minute, that a rotor will vibrate when forced off-balance.
A good example of this concept is a diving board. Having a long diving board means that after you jump off, it will vibrate much more than a shorter diving board. The flexibility or springiness of the longer diving board means that it has a higher resonant frequency. The frequency of these vibrations is high and the amplitude is low. A shorter diving board would result in vibrations with a lower frequency and a higher amplitude. Continue reading “What is Whip Balancing?”
Vibration analysis is not exactly a service that just anyone can provide. Because of that fact, many people tend to ask us to explain what we do. Here are a few explanations for you!
Vibration analysis is a vital service for all rotating equipment, as anything that rotates is bound to vibrate. As components like bearings get older, it’s more likely that the machine’s vibration will increase. This is something that you need to keep an eye on, because the additional vibration can cause the machine to literally tear itself apart. By monitoring your machines & performing routine maintenance, you’re essentially lengthening the lifespan of each machine, which is definitely a good thing. Continue reading “What is Vibration Analysis?”
We wrote about some of our welding services a couple months ago and now we’re keeping our promise about the followup article! As we’ve said before, we offer many kinds of welding services and we want to make sure you know the difference between them. Here are a few more descriptions and explanations of the welding we can perform for you! Continue reading “More About Welding”
Onsite balancing is one of the many services we offer for the equipment that you just can’t pack up and ship out. It’s important to maintain each piece of your equipment so you can enjoy a streamlined workplace. Our onsite balancing technology is top of the line equipment that detects imbalance and helps us figure out how to fix the problem. Continue reading “Onsite Balancing”
Here at Hi-Tek Balancing, welding is just one of the many services we offer. Strike that- we offer way more than just ONE welding service. However, we want to make sure our audience understands exactly what welding is. There’s a reason we can offer so many different services – welding can be done in a variety of ways!
