Large and cumbersome parts with threaded holes are often impossible to remove from wherever they are; they need to have their threads confirmed or cleaned wherever they happen to be. Traditionally, this has meant that when thread verification or thread remediation is required, means are employed to run “GO” gages or taps into the threads. This kind of work is either done by hand or with cordless drills or air drills. Screwing in gages or taps by hand works, but it is terribly slow. Cordless or air drills work also, but there is considerable risk of damaging the entry ends of the holes. Also, with blind holes, there is no certainty about how deep to go.
New Vista has three different handheld types of tools that resolve both these problems. The TC Thread Gun is the most popular of these, because with the TC there is no cord or hose to contend with. Damage to the entry threads is eliminated partly through its torque-limiting mechanism, and partly through the compliant toolholders that are supplied with these Units: the gage or tap will enter straight even if the gun isn’t held straight.
The standard TC Gun is equipped with quick change tooling and depth setting, allowing most internal and external “GO” thread inspections (and cleanouts) to be performed to the correct depth in 4 seconds or less. As always with New Vista designs you get (adjustable) limited torque going in, and much greater torque backing out, eliminating the possibility of jamming in the hole or cross-threading.
The trend to replace hand gaging with powered thread verification is a prime example of technology making the workplace safer and more efficient. Not only will you find that your inspection time is greatly reduced, but your operator’s risk of repetitive motion injuries (carpel tunnel) is all but eliminated when employing the TC Gun. Once set up and running there is very little maintenance required, and most customers see rapid returns on investment.

New Vista’s patented technology extends into a multitude of threading applications: thread verification, thread chasing and retapping are examples. Retapping, for example, has proven to be a particular challenge for automotive part remanufacturers. When parts are brought in for reconditioning, the threads tend to be damaged and dirty. Retapping is what is needed here, and New Vista’s solution for this unique set of challenges is the TSF Thread Unit.
Popular in reconditioned-parts plants, the TSF Thread Unit is capable of retapping damaged threads and cleaning out serious contamination in thread sizes up to M18 (3/4”). Much faster than old style retappers or drill presses, the average TSF cycle is just 3 seconds; allowing an operator to process more parts in a shift. The TSFs will follow the existing threads, and they are equipped with a sensitive high speed drive which causes the spindle to stop when it encounters hopelessly-marred or short threads. These features prevent common retapping problems like cutting out-of-phase threads or breaking tools.

Misalignment is a fact of life in powered thread verification. You can’t avoid it. So how do you prevent, in real life, having the thread gage member jam in a good thread because of misalignment issues? New Vista’s patented torque control mechanism prevents damage even when misalignment is a factor, but for the thread gage member to slither effortlessly through a misaligned thread, you will also need a compliant Toolholder. And in cases of severe misalignment, only a SuperCompliant Toolholder™ will do the job.
As the latest addition to New Vista’s line of thread verification and cleanout solutions, the TC Thread Gun offers unparalleled convenience when inspecting or chasing multiple threads in large parts. The standard TC Gun is equipped with quick change tooling and depth setting, allowing most internal and external “GO” thread inspections (and cleanouts) to be performed in 4 seconds or less. As always with New Vista designs you get (adjustable) limited torque going in, and much greater torque backing out, eliminating the possibility of jamming in the hole or cross-threading.
The International Manufacturing Technology Show is one of industry’s biggest and best shows, and if you’re looking for cutting-edge solutions in manufacturing technology, chances are, you’re going!
This year, take advantage of the opportunity to experience New Vista’s latest innovations in screw thread-verification and thread reconditioning technology. On display will be our most popular products: the STH Unit, SCD Machine and Handheld Gun, among others. You can find information about these products and see videos of them in action before you arrive through New Vista’s website.
In addition to our popular single-spindle STH Thread Unit designs, New Vista offers multi-spindle FLX Heads for integration and multi-spindle FLX Stations to meet your thread-verification requirements. Each FLX spindle has its own separate torque monitoring; and each spindle provides for separate thread depth setting. The threads being gaged don’t need to be all the same size nor the same depth either. As always with the New Vista designs you get (adjustable) limited torque going in, and much greater torque backing out, eliminating the possibility of jamming in the hole.
First introduced to the market in 2008, the New Vista IND (dial type) thread Verification-Machines are the fastest thread-sorting machines in the New Vista arsenal. They can achieve 2-second cycle times and perform other measurement tasks as well. The longevity of these Machines is anchored in robust design and the use of the well-regarded New Vista STH power unit. TVM-INDs are relentlessly reliable, they are compact and they will verify either male or female threads. The latest models have quick-changeover capabilities built into them, and they cost less now than they ever have before.
New Vista’s flagship STHs are the most popular and widely used Thread-Verification and Thread-Reconditioning Units in the world. Favored for automated and robotic applications, the STHs were first introduced to the market in 2006. Having made an early reputation for reliability, today’s models will run either male or female threads; they are more compact, easier to integrate, and accept more accessories than ever before.
Whether the application is thread verification of existing threads, or chasing or retapping deformed or impeded existing threads, it is essential that the correct toolholder be selected. In all cases the tool must follow the existing thread with as little impediment or resistance as possible. Ordinary floating tapholders, or rubber couplings are not suitable for these kinds of work; their use will result in stalling at entry, metal adhesions or out-of-phase rethreading. A properly designed compliant toolholder, will, in contrast, allow the tool to make effortless entry 100% of the time, and then permit the tool to glide easily through any correctly-sized thread.
New Vista’s TVM-ESCs are the most popular and widely used thread-sorting machines in the world. They are used for both “GO” and “NO GO” thread-verifications and are generally served from feeders, magazines or even hand fed. First introduced to the market in 2006, the longevity of these Machines is anchored in robust design and the use of the well-regarded New Vista TVU-STH Power Unit. TVM-ESCs are relentlessly reliable, they are compact and they will run either male or female threads. The latest models have quick-changeover capabilities built into them, and they cost less now than they ever have before.
