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.
New Vista is well known for its large offering of automated thread verification and chasing equipment. But not every application requires an automated solution. If your volume is limited, a powered handheld device may be the answer. If you are still gaging or chasing threads manually, it’s probably for one or more of these reasons:
- The guns you have seen are too slow.
- The gage / chaser tears up the mouth of the hole.
- If you bottom out on the thread, the gun jams, and you can’t back the tool out.
- Tool breakage is frequent.
There is a break-even point when considering whether to integrate a Thread Verification Station into a production line or just hand feed the Station, where the cost of paying a person to move parts is justified over laying out the capital for an automated device to perform this task, or vice versa. This is typically driven by cycle time and the architecture of the production process. So if you have a relatively slow cycle time, and have the personnel, hand sorting may be the best option.
