We are Good at the Processes of CNC Machining

CNC milling

CNC Milling

CNC milling is a subtractive form of manufacturing that uses a cutting tool to moves and rotate to remove material. CNC mills can be used for cutting and machining operations of various plastic and metal materials. It is suitable for any industry that requires precision components and is also an ideal tool for making molds.

CNC Turning

CNC Turning

CNC turning removes material by contacting a cutter with the high-speed rotating workpiece and is usually used to create round or tubular shapes. The CNC turning process allows the generation of complex external geometries and internal holes, including the machining of various threads.

5-Axis CNC Machining

5-axis CNC machining allows complex parts with multiple side features to process up to five sides in a single setup. This can pay big dividends in better machine utilization, reduce setups and cycle times, and improve quality. The ability of 5-axis machining will make our CNC shop more cost-effective for a wider range of work.

With proven expertise, advanced CNC technology and inspection equipment, we have the experience to provide perfect accuracy and repeatability, even for the most complex parts. We are committed to providing precision CNC machining services to meet or exceed customer expectations.

Applications of CNC Machining

Prototype Machining for Your Design Verification and Engineering Testing

CNC prototyping is the process of creating plastic and metal prototypes through CNC machining, allowing your design team to closely simulate the appearance, function, and material properties of the final product, and test the suitability and manufacturability of components to prove and perfect their design.
We offer professional prototype machining services to ensure quality and accuracy, with a commitment to fast delivery.

We specialize in high complexity and high precision prototype machining

– Creating fully functional engineering prototypes that allow you to examine and test the form, fit, and function of components in rigorous working scenarios to help prove and refine your designs.
– Creating aluminum prototypes of complex designs with extended and integrated machining processes gives us the ability to handle a wide variety of aluminum machining projects with extremely tight tolerance control and excellent surface finishes.
– Creating optical prototypes of clear acrylics, high-speed cutting for complex-shaped free-form surfaces and dense optical details using D0.1-D0.3 ultra-fine milling tools, providing micro-milling capability with excellent surface quality.

Custom Machining for Low-volume Production of End-use Components

The advantages of CNC machining are particularly well suited to the requirements of low volume production runs of custom parts, including accuracy and repeatability, flexible processes, as well as a wide range of material options, all of which help bring products to market faster.

CNC Machining Tolerances

QuickMachine’s general tolerance is applied to ISO 2768 (medium) for machined plastic and ISO 2768 (fine) for machined metals. Typically, we can hold a CNC machining tolerance from ±0.005″ (±0.125mm) to ±0.002″ (±0.05mm). If tighter tolerances are required, a 2D drawing with complete information will be necessary. Our engineering team will communicate with you the critical dimensional tolerances and provide the highest degree of precision possible.

Design For Manufacturability

A Quick Guide to Designing CNC Machined Parts

Optimize your designs to avoid unnecessary machining features, limit part complexity, help reduce machining time and costs, and create machined parts faster and more efficiently.

As large an internal radius as possible

Any internal cut will generate a fillet that is half the diameter of the tool used. Milling with smaller tools takes a long time and we recommend that the radius should be greater than 1/3 of the depth of machining. The best bet is to relieve internal corners or allow for as large an internal radius as possible on mating part designs and use the same radius on all inside edges so that the same tool can be used throughout the process.

Avoid overly deep cavities, grooves and holes

The depth of the cavity and groove is usually related to the diameter of the tool used to make the internal fillets, and a good rule of thumb is to keep the cavity depth 3 – 4 times the tool diameter or the groove depth less than 4 times the feature width. Whether blind holes or through holes, the recommended maximum depth is 4 times the diameter and the minimum hole diameter is 1 mm, and it is recommended to design standard size holes. With a standard drill, holes can be machined quickly and with high precision; for non-standard holes, using an end mill will increase costs.

Avoid thin walls

As with tall walls, vibration increases when machining thin features. As a guide, the minimum thickness of thin-walled metal parts should be 0.5-0.8 mm, and the minimum thickness of plastic parts should be 1.0- 1.5 mm. If the walls are for supporting action or taller features, the wall thickness should be increased to avoid vibrations during machining.

Avoid small or raised text

You may need to mark parts with part numbers or company names. Adding text looks really cool, but is time-consuming to process; electrochemical etching or laser marking is usually better. If you must cut text, choose recessed rather than raised text whenever possible, keep it simple and large, with a font depth of no more than 0.3mm.

Stick to the standards for threads

Sticking to standard sizes is also important when creating threads. Length should be kept to a maximum of 3 times the nominal diameter of a hole. For blind hole tapping, it is preferable to add an additional length of at least 1/2 hole diameter at the root of the hole. You might also think about using inserts. threaded coils and brass nuts provide longer service life than bare threads, especially in soft materials such as aluminum or plastic, and are easy to install.
