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.
To see a New Vista TSF Thread Unit retapping threaded holes packed with rust, dirt and plating residue in Brake Calipers, please view Video VTSF3.
Contact one of New Vista’s Application Engineers today to find out what you can save by implementing a more efficient retapping process. Expert applications service is available from our U.S. location and in several other countries as well. Please inquire.
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.
For low volume applications or when there’s a lot of variety, a TVS-SV Thread Verification Station may be your best choice. To see these in action, look at VSV4 and VSV5 . The counter-balanced pantograph makes the Unit easy to maneuver and it keeps the Thread Gage Member straight with the work. Anybody can learn to be proficient with this unit; and crossthreading and jamming won’t be problems anymore.
