CNC Processes We Are Offering

CNC Milling

Compared with CNC turning, CNC milling, especially 5 axis milling can be used to create complex 3D shapes or to apply a machined surface or features to parts made both plastics and metals. The advantage of multi-axis milling machines makes CNC milling process versatile, as well as accurate and repeatable, for creating many different types of part features of complex geometries. Example include holes, curves, slots, angled shapes, and channels. Milling is also ideal for making tooling for pressure die casting and plastic injection molding.

CNC MILLING GUIDELINES
CNC Turning/Lathing

CNC lathes allow us to get high-speed turning of both plastics and metals from bar or block material. The turning process allows the production of complex external and internal geometries, including generating all kinds of threads. For any round shaped components, for example, shafts, worms, spheres, CNC turning is a more efficient method compared with CNC milling.

CNC LATHING GUIDELINES
Electrical Discharge Machining (EDM)

Electrical discharge machining (EDM) is an essential manufacturing process used primarily on tool steels for plastic injection molding or pressure die casting. EDM uses a conductive graphite or copper electrode submerged in a dielectric bath of water or oil. When a high voltage current is applied to the electrode it sparks against the tool wall, etching away at the surface to produce deep holes, ribs, undercuts and surface textures that are difficult to machine conventionally. When done properly, EDM can produce excellent surface finishes with tight tolerances, virtually eliminating the need for secondary polishing.

ELECTRICAL DISCHARGE MACHINING (EDM) GUIDELINES
5 Aixs CNC Machining

Multi-axis CNC machining centers come in three variations: 5-axis indexed CNC milling, continuous 5-axis CNC milling and mill-turning centers with live tooling.

These systems are essentially milling machines or lathes enhanced with additional degrees of freedom. For example, 5-axis CNC milling centers allow the rotation of the machine bed or the toolhead (or both) in addition to the three linear axes of movement.

The advanced capabilities of these machines come at an increased cost. They require both specialized machinery and also operators with expert knowledge. For highly complex or topology optimized metal parts, 3D printing is usually a more suitable option though.

Advantages of CNC Machining

01
Variety of Production-grade Materials

CNC prototype machining can use a variety of production-grade plastic and metal materials, which allows engineers to use the same (or similar) materials as the final part to make prototypes to test the product's performance, function, and manufacturing cost.
02
Consistently Surface Finishing

Prototype machining provides a consistently smooth surface finish with a typical machined surface roughness of Ra 1.6μm and super-finish machined surfaces up to Ra 0.2μm. additional costs.
03
Highly Accurate Parts With Tight Tolerances

CNC machining can create parts with greater dimensional accuracy than most other common manufacturing technologies. During the final finishing machining steps, material can be removed from the workpiece very accurately, achieving very tight tolerances.
04
One-off Custom Parts & Prototypes

In contrast to formative technologies (Injection Molding), CNC machining does not need any special tooling. So, the on-demand production of custom one-off parts and prototypes is economically viable. This is especially relevant for one-off custom metal parts and prototypes, where CNC is the most cost-competitive solution.

How CNC Machining Works?

The CNC (Computer Numerical Control) machining process involves several key steps that transform raw material into finished parts with high precision. Here's a detailed breakdown of the CNC machining process:

CAM Programming

CAM Software: The CAD model is imported into CAM (Computer-Aided Manufacturing) software, which generates the toolpaths needed for machining. The CAM software creates a set of instructions (G-code) that the CNC machine can understand.

Toolpath Generation: The CAM software calculates the most efficient path for the cutting tools, considering factors like cutting speed, feed rate, and tool selection.

Machining Process

Loading the Program: The G-code generated by the CAM software is uploaded to the CNC machine.

Machine Calibration: The operator calibrates the machine by setting reference points, ensuring accurate alignment and positioning.

Cutting Operation: The CNC machine begins the machining process, following the programmed instructions:

Milling: The machine moves a rotating cutting tool along the surface of the material to remove excess material and create the desired shape.
Turning: In a CNC lathe, the material rotates while a stationary cutting tool removes material to create cylindrical shapes.
Drilling: The machine uses a drill bit to create holes in the material.
Tapping: The machine may also use taps to create internal threads in drilled holes.

Real-Time Monitoring: Operators monitor the process to ensure accuracy and address any issues that arise.

Machine Setup

Machine Selection: Choose the appropriate CNC machine based on the part design, material, and required precision (e.g., CNC milling machine, CNC lathe, or CNC router).

Material Preparation: The raw material (metal, plastic, wood, etc.) is prepared and secured onto the machine's work table or fixture.

Tool Setup: Install the necessary cutting tools into the CNC machine's spindle. Tool selection depends on the material being machined and the features of the part.

Zeroing the Machine: The operator sets the machine's coordinate system, establishing a reference point (often called "zero") from which all machining operations will be measured.

Finishing Operations & Documentation

Post-Machining Processes: Once the initial machining is complete, additional processes may be applied, such as deburring(removing sharp edges), sanding, or polishing to enhance the surface finish.

Quality Inspection: The machined part is inspected for dimensional accuracy and quality. This may involve using tools such as calipers, micrometers, and coordinate measuring machines (CMMs).

Assembly or Further Processing: Once the part meets specifications, it can be assembled with other components or undergo additional processes, such as heat treatment or coating, if required.

Documentation: Maintain records of the machining process, including any adjustments made and quality inspection results.

Feedback Loop: Analyze the machining process for efficiency improvements, tool wear, and potential design adjustments for future iterations.

CNC Machining Tolerances

At IDEAL, tolerances are controlled to ISO-2678 Fine (F) for metals and Medium (M) for plastics as standard. Tighter tolerances available on request.
