CNC TURNING

DAMAG can accommodate almost any size and type of turning application. Most work fits within a 50mm (2 inch) diameter capability. Larger diameters typically move to chuck type lathes or short-bar automatic machines.

Swiss screw machining is a specialty at DAMAG. Modern screw machines under 25mm typically use swiss type cutting and holding methods. This method was developed many years ago by Swiss machinery builders which allows the bar stock to move in/out of the cutting area using a sliding headstock. The headstock is the collet that supports the bar material. The cutting of material is done immediately at the collet support to minimize the flex of the bar material. This allows long thin parts to be cut with great precision. DAMAG uses the latest machine and tooling technology to provide cost effective screw machine parts.

CNC MILLING

CNC milling workshop handles a full range of operations including surface milling, contouring, drilling, and threading. It is ideally suited for the precision production of features like planes, grooves, bores, and continuous threads.CNC milling is a process in which the cutting tool rotates and moves into the workpiece to remove the desired material. Milling is categorized into vertical and horizontal orientations, as well as the number of axes of motion. DAMAG has a wide range of milling capabilities to suit your exact need.

CNC MACHINED MAGNESIUM & ALUMINUM ALLOYS ADVANTAGES

UNMATCHED PRECISION & REPEATABILITY

Precision CNC machining achieves tolerances as tight as ±0.02mm, eliminating the inherent variations of as-cast parts. This ensures every component—from medical devices to optical systems—meets exact specifications with perfect batch-to-batch consistency.

INTEGRATED COMPLEXITY & STRUCTURAL EFFICIENCY

The synergy of die casting's net-shape forming and CNC's subtractive machining allows complex features—thin walls, deep cavities, fine threads, and undercuts—to be consolidated into a single part. This reduces assembly steps, minimizes part count, and enhances overall structural integrity.

OPTIMIZED PERFORMANCE & MATERIAL VERSATILITY

Precision machining optimizes material distribution—adding ribs for stiffness or thinning non-critical areas—to create components with an exceptional strength-to-weight ratio. Compatible with aluminum, magnesium, zinc, and specialty alloys, parts can be engineered for specific needs: high thermal conductivity, EMI/RFI shielding, or superior corrosion resistance.

SEAMLESS SCALABILITY FROM PROTOTYPE TO PRODUCTION

The process enables rapid prototyping using machined castings, followed by a seamless transition to high-volume production. Once tooling is proven, thousands of identical parts can be manufactured with minimal variation, offering both agility for R&D and the economies of scale for mass production.

SUPERIOR SURFACE & FUNCTIONAL FINISH

Post-casting machining removes parting lines, ejector marks, and surface porosity. When combined with secondary processes like anodizing or powder coating, surface finishes of Ra 0.4µm or finer are achieved, meeting the highest functional and aesthetic standards for automotive, consumer electronics, and beyond.

At DAMAG, we offer more than just die casting. As a integrated manufacturer, we provide complete secondary machining capabilities, including precision CNC milling, CNC turning, and EDM services, to transform raw die-cast aluminum parts into finished components that meet your exact specifications.

ELECTRICAL DISCHARGE MACHINING (EDM)

EDM also known as die sinking or wire burning is a process in which metal is removed from the workpiece by electrical discharges between two electrodes, separated by dielectric fluid. Imagine an electrically charged hair thin wire that will melt away tiny particles of metal. Wire EDM processing can hold incredibly tight tolerances, create complex and intricate shapes, work with extremely hard or soft materials, and make tiny parts. Advantages of EDM are:

Can hold incredibly tight toleran

Create complex and intricate shapes that would otherwise be impossible with conventional machining

Work with extremely hard or soft materials

Very good surface finish may be obtained

Extremely hole small holes are possible

WHAT IS A CNC MACHINE USED FOR?

At the heart of modern precision manufacturing, CNC (Computer Numerical Control) machines are automated systems that produce complex parts by following programmed instructions.

Material is removed from a rotating workpiece using a stationary single-point cutting tool. Primarily produces cylindrical or conical shapes such as shafts, bolts, and bushings. Performed on lathes or turning centers.

2. CNC Turning

A versatile process where a rotating multi-point cutting tool removes material from a stationary workpiece. Capable of creating flat surfaces, slots, gears, and complex 3D contours through operations like face milling, pocket milling, and contouring.

1. CNC Milling

CNC routers are used for cutting, shaping, and engraving materials such as wood, plastic, and metal for applications in woodworking, signage, and prototyping.

3. CNC Routing

Using an abrasive rotating wheel to achieve extreme dimensional accuracy and superior surface finishes. Processes include surface grinding (flat surfaces), cylindrical grinding (external diameters), and centerless grinding (high-volume production of small cylindrical parts).

4. CNC Grinding

Creating round holes in a workpiece using rotating drill bits. Includes standard drilling, reaming (finishing existing holes), and tapping (creating internal threads). Often combined with milling in machining centers.

5. CNC Drilling

A thermal process using a focused, high-power laser beam to melt, burn, or vaporize material. Highly precise for cutting complex 2D shapes in sheet metal, plastics, and composites with minimal heat-affected zones.

6. CNC Laser Cutting

CNC plasma cutting machines use a plasma torch to cut through electrically conductive materials like steel, aluminum, and copper for applications in fabrication, construction, and metalworking.

7. CNC Plasma Cutting

CNC waterjet cutting machines use a high-pressure jet of water mixed with abrasive materials to cut through a wide range of materials including metal, glass, and stone.

8. CNC Waterjet Cutting

Enlarging and refining pre-existing holes to achieve precise diameters, superior roundness, and fine surface finishes. Essential for achieving high-precision bore tolerances in engine cylinders and bearing housings.

9. CNC Boring

A non-contact process that removes material through controlled electrical sparks (discharges) between an electrode and the conductive workpiece. Ideal for hardened steels and intricate shapes. Includes wire EDM (using a thin wire electrode) and sinker EDM (using a shaped electrode).

10. Electrical Discharge Machining (EDM)

HOW DOES A CNC MACHINE WORK?

A CNC (Computer Numerical Control) machine is a manufacturing system that automates the machining of parts through precise, programmed instructions. Here’s how it works, from design to finished part:

1. Design & Programming

2. Machine Setup

3. Execution & Machining

4. Monitoring & Adjustment

5. Completion & Inspection

2. Dramatically Increased Productivity

They operate continuously, 24/7, with minimal supervision. Complex parts are produced much faster due to automatic tool changes, optimal pre-programmed speeds/feeds, and the elimination of manual adjustments.

3. Ability to Manufacture Complex Geometries

CNC machines can effortlessly create intricate shapes (like 3D contours or complex curves) that are impossible or prohibitively time-consuming to make on manual machines. This is enabled by multi-axis simultaneous movement.

5. Enhanced Safety

The operator works primarily at the control station away from the cutting tools, spindle, and coolant, significantly reducing the risk of accidents associated with direct contact with the machine.

6. Consistent Quality and Reduced Scrap

Automated, program-controlled processes ensure consistent cutting conditions. This leads to predictable, high-quality finishes and significantly lower rates of waste material and defective parts.

4. Exceptional Flexibility and Rapid Changeover

Switching to a different part production only requires loading a new program and setup. This allows for efficient small-batch or one-off production, drastically reducing downtime compared to retooling a conventional machine.

Six major advantages of CNC machine tools over conventional machine tools:

DAMAG Diecast’s precision CNC machining services offer high-quality, accurate, and efficient manufacturing solutions for a wide range of industries.

1. Unmatched Precision and Repeatability
