Custom Complex CNC Turned Parts

At Polestar, we understand that it is essential to meet the technical specifications of customers’ orders in an accurate and timely manner. To do so, we use ISO standard inspection techniques and provide Computer Measuring Machine (CMM) reports for our customers’ review. Additionally, our team runs thorough dimensional inspections on the manufactured parts to ensure each piece is error-free. We can also offer either a 2D or 3D scan depending on the customer's Computer-Aided Design requirements. To further ensure top quality metal parts, excellent raw materials are used therefore only reliable CNC turning techniques are applied. Nevertheless, we maintain the highest safety and quality standards set by ISO9001-2015 when producing CNC turned parts in high volume quantities.

HOW ARE CNC TURNED COMPONENTS MADE?

CNC turned components are manufactured using computer numerical control (CNC) machining processes, specifically CNC turning. CNC turning is a subtractive manufacturing process that creates cylindrical or round-shaped components by removing material from a workpiece. Here’s an overview of how CNC turned components are made:

DESIGN AND CAD/CAM PROGRAMMING

The process begins with the design of the component. Engineers or designers create a detailed CAD (ComputerAided Design) model of the part they want to produce. Once the CAD model is complete, CAM (ComputerAided Manufacturing) software generates the CNC program to control the machining process. This program contains instructions for the CNC machine on moving the cutting tools to shape the workpiece.

MATERIAL SELECTION, WORKPIECE, AND TOOLING SETUP

The next step is to select the appropriate material for the CNC turned component. Common materials include metals like aluminum, steel, brass, and plastics. A raw material, known as a workpiece or blank, is secured in the CNC lathe machine’s chuck or collet. The chuck holds the workpiece in place while it rotates. The CNC machine has various cutting tools, drills, and inserts. The appropriate tooling is selected and installed in the tool turret or toolpost of the CNC lathe.

CNC MACHINING

The CNC program is loaded into the machine’s computer, and the machining process begins. The workpiece rotates while the cutting tool moves along its length to remove material and create the desired shape. CNC turning machines can perform various operations, including facing, drilling, threading, grooving, and contouring. The CNC machine’s computerized control system precisely coordinates the movements of the tool, ensuring high accuracy and repeatability.

QUALITY CONTROL AND SECONDARY OPERATIONS

During the machining process, operators may periodically measure the dimensions of the workpiece using precision instruments like micrometers and calipers to ensure it meets the design specifications. Visual inspection is also performed to check for surface finish and any defects.

Depending on the specific requirements of the component, secondary operations such as heat treatment, plating, or coating may be performed after CNC turning to enhance its properties or appearance.
