Machining Services

The time it takes to receive a CNC machined part from U-Need can vary based on a few factors. These include the complexity of the part's design, the type of material chosen, and our current production schedule. CNC machining is known for its speed, especially for simpler parts, which allows for fast turnaround times. In fact, parts can be delivered in as little as one day after the machining setup is finished! For the most accurate estimate of time tailored to your project, we suggest reaching out to us directly for a detailed quote. This way, we can give you a precise timeframe based on your specific needs.

At U-Need, we recognize the varied requirements of our clients, from individual prototypes to extensive production batches. As a result, we do not impose a rigid minimum order quantity (MOQ). Whether you need a single machined component or a large quantity, we are prepared to deliver customized solutions that align with your exact specifications. Our adaptable method guarantees that every customer, no matter the size of their order, receives top-notch service and excellence.

The cost of our CNC machining service can vary depending on the specific details of your project, such as design and tolerance requirements. The type of material chosen and the machining time required also play a significant role in determining the overall cost. For example, if the total cost for machining and material for one part is $2, with an additional setup fee of $200, the total cost for that part would be $202. However, if you were to order 200 identical parts, the cost per unit would be reduced to just $3. Find out more about the costs associated with CNC machining.

A machining center is a sophisticated CNC machine that can perform milling, drilling, and tapping tasks in one setup. This setup improves efficiency and accuracy by eliminating the need to move parts between machines. Machining centers have a tool turret or magazine that can hold various tools, allowing for automatic tool changes controlled by CNC. This feature enables quick transitions between tasks, streamlining production. These machines are essential for manufacturing intricate parts that need precise machining from different angles, making them crucial in today's manufacturing industry.

CNC machining is well-known for its precision and ability to produce intricate and detailed parts with tight tolerances. Typically, standard CNC machining can maintain tolerances within ±0.01 inches (±0.127 mm). At  u-need, we adhere to standardized tolerances unless otherwise specified. For projects requiring even higher precision, advanced CNC machines can achieve tolerances as tight as ±0.0002 inches (±0.005 mm) under ideal conditions. The achievable tolerance is influenced by factors such as material, part geometry, size, and the specific type of CNC machine being used. This level of precision makes CNC machining the preferred choice for industries that demand highly accurate components, including aerospace, medical, and automotive sectors.

G and M codes serve as the command languages utilized in CNC machining for the purpose of managing CNC machine tools. G-codes are mainly utilized to dictate the machine's movements, including linear interpolation, circular motions, and other particular functions associated with the tool's actual path. On the contrary, M-codes are responsible for managing machine functions that are not directly linked to the tool's path, like powering the machine on or off, initiating or halting the spindle, and regulating coolant flow. When combined, G and M codes offer a thorough set of directives that CNC machines adhere to in order to fabricate parts with precision and efficiency.

John T. Parsons is widely recognized as the pioneer of CNC machining. In the late 1940s, Parsons introduced the first numerical control techniques in the production of helicopter rotor blades. Teaming up with engineer Frank L. Stulen, Parsons devised a method that utilized punched tape to direct machine tools. This groundbreaking approach laid the foundation for the advancement of CNC (Computer Numerical Control) technology. Their innovative efforts led to the development of the first CNC machines in the 1950s, transforming the manufacturing industry by enhancing the accuracy, productivity, and consistency of machining processes.

Production Process: The process of creating products using 3D printing involves adding layers of materials like plastic or metal, while CNC machining involves removing material from a solid block to achieve the desired shape.

Efficient Use of Materials: 3D printing is known for its minimal waste as it only uses the necessary amount of material for each part, whereas CNC machining can result in more waste due to its subtractive method.

Speed and Cost Efficiency: When it comes to producing small quantities and intricate designs, 3D printing is often quicker and more cost-effective. On the other hand, CNC machining is better suited for larger production runs and materials that require high levels of precision and strength.

Quality of Finish and Precision: CNC machining is typically superior in achieving smooth surface finishes and precise tolerances compared to 3D printing.

Advantages of Computer Numerical Control (CNC) Machining
Precision and Consistency: CNC machining guarantees precise and consistent reproduction of parts, essential for intricate designs with strict tolerances. Minimized Human Error: The automated process of CNC machining reduces the risk of human error, improving the overall quality of manufacturing. Productivity and Speed: Automation enables faster production cycles, leading to quicker turnaround times compared to manual methods. Versatility in Materials: CNC machines can handle a wide range of materials, such as metals, plastics, and composites, providing flexibility for various applications. Integration of Software: Advanced CNC software allows for quick design modifications and updates, simplifying rapid prototyping and customization. Cost-Effective for Large Productions: Although initial setup costs are high, the per-unit costs decrease significantly with larger production quantities, making it a cost-effective option for mass production.

Disadvantages of CNC Machining
High Initial Investment: CNC machinery and its upkeep require substantial financial investments, resulting in expensive setup costs, particularly for small-scale businesses. Skill Demands: Operating CNC machinery requires specialized training and expertise, which can be a challenge for individuals without the necessary skills.
