What are precision CNC turning parts?

With such a wide range of applications, turned parts can serve industries such as electronics, automotive, appliance, HVAC, marine, medical, telecom, petroleum and optical. Precision medical parts are complex components with tight tolerances. They are composed of sanitary grade materials such as titanium and stainless steel to ensure compliance with medical standards. The new turning process offers design capabilities and structural advantages that cannot be replicated cost-effectively by any other manufacturing method, resulting in turned parts with excellent depth and dimensional accuracy. The following information about precision CNC turning parts was found to be helpful.

（1)        What is precision machining?

If you are interested in precision CNC turning parts, you may want to learn more about machining, especially precision machining. Precision machining is a growing area of manufacturing that affects our daily lives. As such, it is a key contributor to the field today. But what, precisely, is precision machining? How can you get involved? Let's explore this ever-evolving field and how to precisely conduct your machining business.

Precision machining is the process of removing excess raw material from a workpiece while maintaining a close tolerance finish to a finished product. In short, this means forming large pieces of material into more precise parts so they can meet very precise specifications. This process involves cutting, milling, turning and electrical discharge machining and is typically performed using computer numerical control (CNC) equipment.

Precision turned parts are created by CNC turning and can be done using either a CNC screw machine or a CNC lathe. CNC screw machines are multi-pinch and can machine multiple parts simultaneously while achieving high productivity. CNC machine turning begins when a round, square or hexagonal blank is attached to the collet chuck of the spindle.

Next, with multiple automatic cutting, drilling, grooving and knurling tools attached to the machine, this blank begins to rotate, and by scraping off excess material, smoothing and drilling, the blank is machined into a precision turned part. The main drive shaft of the Swiss screw machine powers the machine's spindle work axis and controls the two front camshafts.

The machine motor, located at the bottom of the machine, is the central power source for all operations and horsepower will vary depending on the size of the machine, speed and stock to be machined. A CNC lathe is a computer-controlled machine capable of forming precision turned parts by holding and rotating the blank (also called a workpiece) on a single spindle while the drill performs the cutting action.

CNC lathes are a recent development because less is thought to be known about lathes, so they are often considered easier to set up and operate, and as a result they are rapidly replacing older lathes. Often, precision turned parts manufacturers have the same operator and set-up man.

Precision machining produces many of the large and small objects we use in our daily lives. Believe it or not, every small part of an object requires a certain level of machinist skill. Likewise, tools or machines that have worn out often require machine tools to be calibrated, welded or grooved by a precision machinist. Precision machining involves every technology and industry, from automotive production to surgical instruments and aircraft parts. So, basically - if the product contains parts - some precision machining is required.

Successful precision machining requires the ability to follow extremely specific blueprints developed by computer-aided design (CAD) or computer-aided manufacturing (CAM) programs. This CNC machining parts technology creates 3D drawings or contours to produce machines, objects or tools. Blueprints must be carefully designed to ensure quality and success.

Precision machinists can produce precision CNC turning parts using a variety of materials such as bronze, glass, graphite, plastic, steel and other metals. depending on the size of the project and the materials involved, a variety of precision machining tools and techniques will be used. Therefore, machinists must be proficient and experienced with these different processes and equipment. They can use any combination of drill presses, grinders, lathes, mills, saws and even high speed robots to complete precision CNC turning parts jobs.
