New Vista SuperCompliant Toolholders

Supercompliant Toolholder

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.

Ordinary floating tapholders, of the type used in tapping operations, are not suitable for this kind 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 permit the tool to glide easily through any correctly-sized thread.

You can see New Vista’s SuperCompliant™ DDG Toolholder demonstrating out of position thread verification in this Video VSCC30. The New Vista DDG Toolholders include the following features:

  • They will work with a large variety of powered thread-verification and thread-chasing Units.
  • They are self-centering.
  • They eliminate jamming, cross-threading and, in high torque applications, off-axis re-cutting resulting from misalignment between the tool and the threaded feature.
  • They will find and follow threaded holes (or external threads) that are out of position up to 5mm (Ø10mm true position); or out of square up to 3º.
  • They have a high torque rating due to sophisticated Oldham principle design.
  • They can be repurposed for new applications in a matter of minutes. No disassembly or shims are required.

There are several different variations in the SuperCompliant™ family. You don’t need to be an expert in thread verification techniques to decide which one to choose. Contact a New Vista Applications Engineer today for more information regarding the New Vista line of Compliant Toolholders. Applications service is available from New Vista’s Baltimore, MD (USA) location and in several other countries as well. Please inquire.

New Vista Handheld Thread Verification & Cleanout

TC Thread Gun - New Vista CorpAs 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.

New Vista Multiple-Spindle Thread Verification

multi-spindle FLX headsIn 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. Continue reading

New Vista IND Thread-verification And Sorting Machines

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. Continue reading

New Vista STH Thread Units

New Vista STH UnitsNew 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.

The New Vista Supercompliant DDG Series Toolholders

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.

TVM-ESC Thread Sorting Machines

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.

Pantograph-Mounted Thread Verification Stations

Old style New Vista SV setup shown aboveThree thread sizes, our hole patterns on 3 surfaces; hole-to-hole time is 2.5 seconds. Fixturing is simple; or, in many cases, not required at all.

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.

Handheld Thread Verification and Chasing

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.
