  1. Screw Threads and The Threading Operation

    Leave a Comment

    Screw threads are an often overlooked and underappreciated invention. This device, an evolution of primitive nail technology, dates back to ancient Greek inventors Archytas and Archimedes as far back as 400B.C. The original purpose was to apply gradual pressure from a crank shaft on olive and grape presses for oil and wine. During this time and for centuries thereafter wooden screws were the norm. Artisans used their skills to produce them by hand, a very difficult and precise operation, until 1797 when Henry Maudslay (1771-1831), an English mechanical engineer became the founder of the machine-tool industry by inventing the screw cutting lathe. This made uniformity in screws and future threading operation technology more than a possibility.

    Screws and Standardization

    Until Maudslay, manufacturers produced screws with a distinct lack of uniformity in screw threads. The number of threads varied dramatically from manufacturer to manufacturer making any standard impossible to achieve. However, in spite of Maudslay’s work, the situation remained chaotic until World War I broke out. It was during this war that the American National (AN) thread form was established. It remained the standard of all major threads produced in America until World War II.

    Not all manufacturers conformed to the AN standard around the globe. During World War II, when American, British and Canadian allies worked on tank and other military equipment construction, issues of compatibility arose. The screws were not interchangeable. These presented problems that the countries did not overcome until following the cessation of the war.

    In 1948, a new standard arose. This, agreed upon by many countries, became known as the Unified thread form. It is in universal usage. It also affects what products emerge from the threading operation of a machine shop.

    What Exactly Is Thread Turning?

    Thread turning is, at its most basic, the production of threads – male or female. It involves the use of such tools as universal lathes and CNC machining. In order to achieve the right thread design, the operator must select the right profile and tool position. In multi-stage thread production, the operator must apply the tool several times at the identical point of the perimeter of the workpiece.

    In thread turning, the machinist will also face certain constraints. They tend to be the ones associated with most production and/or finishing work.

    • Time
    • Budget
    • Requested level of precision
    • Available equipment

    These restrictions may reduce the capability but should not affect the overall quality of work under a skilled machinist.

    The Threading Operation

    Thread turning is a very demanding form of turning operations. Yet, over the centuries since the invention of the threading lathe, new technology has made the process both easier and less time consuming. In fact, it allows the operator to specify certain aspects allowing him or her to select the type of machining based on whether the thread is to be male or female, external or internal. For a threading operation today, an operator can take advantage of many different thread-machining options to produce an excellent workpiece. JBC Machine is no different. We have highly skilled machinists who can produce consistently excellent threading to exacting specifications. Call us for your next threading project!

  4. Prototype Machining: Making A Theory Functional

    Leave a Comment

    If a manufacturing company wants to produce a new product, they start with the design process and end with production. In between the theoretical design and the final product for consumers lies the prototype. Today, no manufactured product arrives on the market without first going through a prototype. Machining is one way to produce this concrete mock-up.

    Why Create a Prototype?

    Prototypes are the step before production. They are the means by which a company can discover a variety of information about their intended product. They can learn:

    • If the product is actually functional
    • If the materials are practical or they need to cater to suit the environmental or regulatory structures and specifications
    • If the design is at all useful or requires retooling or adjusting

    An essential early step in the verification phase, prototypes allow a company to explore the possibilities of the design without expending money on a production run that might result in abject failure of the product in some fashion. In other words, no matter how good the product design may look on paper, its functionality in the real world is what matters.

    Prototype Machining

    Prototype machining by JBC Machine allows manufacturers to not only study the appearance of the product, and/or its component, but also test it. As a prototype, it is now a three-dimensional work capable of undergoing a variety of tests to check its quality, durability, Failure Mode Effects Analysis (FMEA) and similar properties. However, the initial rendition may not be the model that goes to production. It is not unusual that the complexity of the process may demand several iterations or variations of the prototype before a final decision is made. The automobile industry is a classic example of this.

    For the automobile manufacturers, the process is cost-effective. They can afford the expense of several models. Not all industries can. It is beneficial for them to work with machining companies such as ours to decrease any instances of a flawed design making it from paper to prototype. Our team of professionals has the expertise to help your company with its prototype. They also have the equipment to handle the specifications of a design.

    Our modern technology and innovative approach backed up by expertise and years of experience combine to make available to you a high quality prototype. It comes complete with whatever is required for a production run in the future. This includes programs, fixtures and inspection documents essential to the successful production of the prototype. At JBC Machine, we work with you, your personnel and plans to provide prototype machining that produce impeccable results.
