What Is Precision Machining?

Posted on Nov 4, 2020

Precision Machining

Precision machining is type of technical manufacturing used to create and design machines, parts, tools and other hardware that are essential in modern manufacturing. This allows machining process to be controlled which enable function under exceptionally tight specification.

Precision machining is used to integrate objects both large and small and other precision components that are used daily. If an object or item is to be created with many small parts, it is required to ensure the perfect fit of these parts, thereby allowing proper functioning.

Precision machining has obviously evolved over time and has done an even better job at improving performance consistently using all the related technologies and advancements. It is especially essential for creating tools and parts in a way that is precise, stable, and can be repeated with consistency, accuracy, and durability.

How Does Precision Machining Work?

Precision machining is essentially a subtractive process that utilizes custom software, engineered tools and raw materials such as plastic, metal and ceramic to create the desired fine-featured products. It is often undergone according to the instruction generated by computer-aided design (CAD) and computer-aided manufacturing (CAM) programs. These programs and the generated blueprints make meeting tight tolerances much easier. On a side note, many of these designs start out as hand-drawn sketches in the initial phases despite eventually fed into engineered and computer-aided programs.


What Are Used along with Precision Machining

Precision machining is often used with a handful of raw material such as plastic ceramic, metal, composites, steel, bronze, graphite and glass. For making precise cuts and removing raw materials intricately, an assortment of tools can be used. What you use is entirely based on the raw material used. The frequently used tools are milling machines, lathes, saws, grinders, and Electric Discharging Machine (also known as EDM).

Most frequently used manufacturing equipment is computer controlled heavy-duty machinery that is mean to remove substrate material in order to create intricate components and parts. Sometimes, high speed robotics and photochemical process may even be used to fulfil the intended result for the final product. Precision machining is utilized to create both small and large objects and parts based on strict manufacturing guidelines specifications and critical tolerances.


Precision Machining Application

Generally speaking, precision machining is required when material needs to be removed from a raw product to create the finished product. It is extremely versatile in a sense that a wide variety of products, objects and parts on an industrial basis can all take advantage the machining technology.

The parts to be machined generally require tight tolerances variation from nominal dimensions and from part to part, meaning that there is not much room for error during the machining process. Fortunately, reliability and precision are the representing characteristics of precision machining.

Another common application involves tools or components requiring a repair or restoration. Upon being use for a periods of time, the tools or components of an item may require calibration, grooving or welding to restore them to the former state, and precision machining can do just that.


What Are the Benefits?

There are several advantages to precision machining, including:

  • Reliability:
    It can occur continuously without any breakdown no matter the time or day of the week. The raw materials are converted into the final product and ultimately released into the market as high quality tools. One of the key upsides is that breakdowns are not likely to occur when maintenance is required or during a repair.
  • Low requirement for human power:
    Due to the significant advancement in technology over the years, precision machining in manufacturing industries is automated. The process is mainly controlled by robots or computers which minimal human labor is required to monitor them. This also hugely cut down production cost, as well as the need for supervision and oversight of the process.
  • High production:
    Despite the intricate nature of the operation, it is able to generate substantially high productivity by tending to a massive amount of work such as drilling, finishing, milling, spinning, etc. in a relatively short period.
  • Consistent Result:
    Despite the high production rate, the finished products are identical and have very little chance of errors. The resulted products in turn become more marketable due to their high consistency, improved quality and low faulty rate.
  • Increased profit and reduced effort:
    A key benefit is that minimal effort is needed to yield optimal profits. The fact of the matter is that with a metal that undergoes precision machining, not only do you save production cost, but it will also save much of your time and effort which ultimately guarantees highly cost-efficient production.
  • Increase accuracy:
    Most of the objects and parts undergoing precision machining are used in the manufacturing industries. This includes places where manual turning and milling are required. It can also be utilized in healthcare sector where accuracies are highly looked upon. In light of this, they are equipped with the ability to operate on a highly accurate basis, thereby completing the intended tasks effortlessly.
  • Enhanced efficiency and quality:
    When machining the objects and parts, they are always fitted with internal quality assurance detectors. This allows efficiency to be ascertained while the objects are being machined with fast pace. Moreover, it is known for meeting high level standards object working and parts fabrication. Along with the lessened expenditure cost (e.g. the expense on human labor, etc.), it is extremely cost-efficient that ensures both product quality and low money wastage.
