FREQUENTLY ASKED QUESTIONS 1. What standards cover the process of Cold Root Rolling? A. Both NS-1 and DS-1 have standards in place that cover the process of Cold Root Rolling to one extent or the other. Many of the major Rotary Shouldered Connection OEMs also have internal standards that cover some aspect of this process.…
Please contact your local Postle Representative or Technical Center for any information on proper weld parameters. Managing the heat of the welding process is absolutely critical during the hardbanding procedure. Proper pre-heating and slow cooling will assist the weld metal and the base material (tool joint, tubing upset, or other downhole tool) through their metallurgical…
What is a MOPA Fiber Laser Engraving Machine and How Does it Work? A MOPA fiber laser is a sophisticated laser system that utilizes a master oscillator and a power amplifier to generate high-power laser output with exceptional precision in controlling pulse parameters. This design is extensively employed in a diverse range of industrial and…
The beginning The concept of a set of gauge blocks that can be used to assemble a gauge to accurately represent almost any practical length from a small number of pieces was invented by Carl Edvard Johansson (Figure 1), a Swedish machinist, in 1896 and therefore has more than a century of history. Figure 2…
Air gaging has many advantages as an inspection method. It is quick and easy to use, requiring little skill on the part of the operator. It is highly adaptable to measuring special features for both dimensional and geometric tolerances, ranging from simple IDs and ODs to taper, flatness, and runout. With different tooling readily installed…
Surface plates provide a large flat reference surface that can be extremely useful for inspecting incoming, in-process, or finished parts. The surface plate is oftentimes referred to as the foundation of measurement since it provides the reference for much of the layout work done in an inspection cell. When used in combination with various gages…
It’s All About the Chemistry Each hardbanding product has its own, unique chemical composition, no two materials are the same. For example, some materials form Chrome Carbides or Titanium Carbides to provide wear resistance. The matrix which holds the carbides is also different for each product. The chemistry of Duraband®NC was formulated to ensure that…
The new generation of electronic comparators The new Millimess 2000 W(i) and 2001 W(i) series of electronic comparators set new standards in metrology – thanks to unique and innovative features. Touch operating keys: Reliable operation in the measuring system Fully hardened glass display: Robust and completely insensitive Linearized inductive probe measuring system: Integrated measuring system…
The use of electronic temperature compensation in gaging has become a valuable tool in improving the accuracy and GR&Rs of gages in harsh manufacturing environments. The need for temperature compensation comes into play when the expected errors from temperature variation caused by the environment can use up more than 10% of the part tolerance. Where…
In the world of craftsmanship and industry, precision and permanence are often paramount. When it comes to marking various materials, steel hand stamps have played a vital role for centuries. These unassuming tools are capable of leaving an indelible mark on a wide range of surfaces, from metal to wood and even plastics. In this…
