Precision Machined Parts

Many companies greatly depend on precision machined parts. As a matter of fact, most products make use of them. During the fabrication process, precision machining is a step that allows the creation of small parts by remove excess raw material. The process that is used is known as jig boring or milling. Once the items are ready, they are used in the production of a variety of products, such as cars, clocks, hospital tools, and airplanes. Precision machined parts are just one of the many products and services offered at many manufacturing facilities. Most will use state of the art CNC and mechanical equipment and hire highly trained machine operators to run the machines. A company that provides precision machined parts, typically, has a lot of experience in making design solutions for customers. To make the process smooth, process engineers and machinist will work together to make improvements to the part’s design. The goal is to make a quality product at a reasonable cost and in a timely manner. Companies that manufacture precision machined parts have a lot of CNC programming and modeling experience. These companies also give advise such as recommendations as to the size of the products. Machine operators will have access to many of the machines to determine which machine is best suited for the requested materials. Whether the job requires aluminum, bronze, Dura-Bar cast iron, several types of steel, nylon, or any other material, the operator will decide how to best create the product using the specified materials. Usually, the manufacturer can create the whole component with just a single tool. This reduces the cycle time, setup time, and allows for better control over the process. In addition, it allows the company to deliver a high-quality product during a short period of time. The best companies in the industry will provide precisely manufactured parts by using the best machining...

Understanding Electrical Contacts in Control Circuits

Control panels have the power to start and stop machinery manually or automatically. They also offer valuable protection from overload conditions. One of the most important features includes their electromechanical assemblies and contacts, but what are electrical contacts and why are they so important in understanding control circuits? Let’s look closer at this issue to see. What is an Electrical Contact? Electrical contacts are two pieces of conductive metal with the ability to come together and draw apart. This action connects or disconnects conductors in circuits. When you flip a light switch to turn on a light, two sets of contacts come together. Each contact connects to a terminal, and each terminal has a wire (conductor) connected to it. The light circuit must pass through the switch to complete, and with the contacts closed, the light comes on. Turning the switch to “off” breaks the contacts apart, and the light goes off. Contacts for Electromechanical Assemblies Contacts in components like motor starters and contactors work the same way as simple single pole switches, except they rely on electromagnetic energy to open and close. Here is how an industrial refrigeration compressor works: The thermostat has two sets of contacts which are normally open (apart).A spring mechanism connects to the bottom contact. Heat causes the sensitive spring to expand, pushing the bottom contact up until it touches the top contact. This sends current to the compressor contactor. The contactor has a coil of wire which becomes magnetized when it receives electric current (like all electromechanical assemblies). This pulls the contacts together, sending current to the compressor and it comes on. When the temperature in the thermostat gets cool enough, the spring compresses and pulls the contacts apart. This stops current from reaching the contactor, and it’s no longer magnetized. The compressor loses its power and stops...

Finding Top Military Wire Harness Manufacturers

There is a difference between a wiring harness and a cable assembly, although the two are often used interchangeably and outside of the engineering and design team discussions. A wiring harness can include a single wire or a group of wires, each with their own sheathing, that are then collected and held together, typically with a woven braiding material or tubing. They can also be held together with ties, the specific type of binding will be determined by the specific application and the environment where it is used. While it can connect components, it often provides the electrical connection for an entire system. A cable assembly, on the other hand, consists of one or more wire cables that have a thermoplastic sheath covering the wires. It will usually connect just two components. These are often used for outdoor applications because of the additional layer of protection. They are also used in high-demand or extreme types of environments for interior wiring as well. Getting the Best Choosing the best cable assembly and military wire harness manufacturers will be important for defense contractors requiring specific components and parts of equipment including engines in military vehicles, telecommunications, radar systems, military vehicles and networking. Finding the best military wire harness manufacturers starts with getting to know the industry. There are only a small number of companies that have the approval and ability to produce to the required military standards as well as to ITAR (International Traffic in Arms Regulations), required for the import and export of specific types of military-related technologies. Reviewing websites of the top military wire harness manufacturers will allow you to determine the scope of services available. Of course, you will also want to compare the quoted price for the services requested, the timeline the manufacturer can deliver on and the background of the company specific to working with military and defense...
