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.
Until relatively recently, manufacturers of auto and truck parts, medical and aerospace components and the like, relied on sampling inspection of threads using hand gages. But in the last dozen years, with an accelerated trend toward automated assembly; and with increased outsourcing of machined parts, it has become more urgent for them to move toward automated 100% thread gaging for many critical components.
