Thread plug gauge

Thread plug gauge

Used to test internal thread products, threaded plug gages usually have both GO and NOHGO parts. To distinguish between the two, the GO part is longer and includes an easy-to-clean chip slot in a larger size. If no significant force is applied, the part that is done will be fully connected to the tolerable nut. Before binding, the NOHGO section will not be able to carry out more than three “good” parts. When a part passes the GO test, the hole is large enough to accept its matching axis without undue stress. When it fails in the NOHGO test, the hole is small enough to allow a strong, tight body. These conditions must be met within the specified tolerances.

Thread ring gauge

In contrast, ring gages tests the accuracy of external threaded parts. Also, when it passes through the ring completely, the bolt is considered tolerable, but it only needs to rotate less than three times. The gages of the solid ring determine that the screw pitch and diameter of the thread can be calibrated to a specific threaded plug or the owner and should be purchased with the ring. Adjustable ring gages can be recalibrated and recalibrated after prolonged use, shipping, exposure, or other conditions that may lead to slightly altered Settings.

Set (main) collateral

Unlike “work” plugs and ring-shaped gages, gages are not meant to be used directly for test parts because of their tight tolerances. Instead, they calibrated the new ring and inserted gages, and checked their continuous accuracy for their functional life cycles. To make and prove the thread ring gauge, a set plug is required, and the GO/NOHGO set plug is usually ordered with the corresponding ring.

In the same case, parabolic grooves can be used to design drills in more rigid materials and deep holes.

The cobalt drill is designed for drilling hard material, which is constructed with a split-point to make it easy to start.

During the development of super large materials, we have determined the machining characteristics of different grades of stainless steel, with different flute shapes, chamfering angles and convex angles. Stainless steel material (free machining) can effectively use titanium alloy coating faucet, improve surface finish and extend tap life.

Let’s start with an example: 3304 stainless steel is a good level of corrosion and strength, but if 303 is satisfactory,
