Custom manufacturers of precision CNC machined parts use specialized CNC machinery to create precision parts that meet customer specifications. Precision CNC machines can handle aluminum, alloy steel, stainless steel, and plastic materials, and can perform operations such as 11-axis swiss turning, 5-axis horizontal milling, and micromachining. They can meet the needs of industries like aerospace, defense, medical, and technology. Depending on the nature of the parts, custom manufacturers may offer a wide range of custom manufacturing services, from small precision parts to complex prototypes.

Precision CNC machining processes elevate parts and processes to a higher level of quality. Although precision is not essential for all parts, it is crucial for certain applications. Precision can be improved through design and machining, as well as careful inspection and quality control. Here are some important factors to consider when choosing a CNC machining partner. These factors should be discussed early in the process. By establishing expectations early on, customers can avoid costly mistakes that can hinder the success of a product.

Choosing a multi-axis CNC machine will enable it to produce complex geometries in a single operation, reducing operator error. CNC machines also use high-pressure coolant, preventing chips from entering the working space. Several types of milling machines are available, varying in size, axis configuration, feed rates, and cutting speed. When selecting a machine, consider the specific needs of the project.

When selecting a CNC machined part manufacturer, consider how much tolerance is needed. The tighter the tolerance, the more expensive it will be. To reduce this cost, consider opening tolerances. Different types of anodizing are available, each of which has a different advantage. Hard-anodized parts are extremely durable, but require more machining. In general, a tolerance of a few mils is sufficient for most applications.

Turning is one type of precision CNC machining. The process involves rotating the workpiece next to a single-point cutting tool. Typical turning tools include lathes, including turret and engine-purpose lathes. Turning equipment also includes straight and taper turning. Drilling is another type of CNC machining. Drill bits are multi-point rotating tools that make cylindrical holes. The design of the bits makes it possible for the chips to fall away from the workpiece.

Precision CNC machining is ideal for finishing metal products. It can restore worn parts that are created through die casting and other fabrication methods. It can also be used to repair damaged and worn parts. Unlike manual cutting and die casting, computer-aided equipment allows for a more consistent finish on these parts. In addition, CNC machining can eliminate a high cost associated with lost opportunity. It's also the most reliable option for producing parts with a narrow tolerance margin.

Precision CNC machining requires special equipment and the ability to follow the blueprints created by CAM or CAD software. CNC machining technology generates three-dimensional diagrams and outlines for production. To ensure precision and quality, the blueprints need to be precise and accurate. Most precision machining companies employ both CAD/CAM programs and hand-drawn sketches in the design phase. Then, the machinists load the design files into the CNC equipment.
