In general, it is possible to cut metal with both CO2 and fiber laser. Metals such as steel or ferrous materials can be cut more easily than light or non-ferrous metals such as copper or aluminum.

The contactless marking process of metal, without consumables or tool wear, ensures the lowest costs per marking. In contrast to marking with a CO2 laser and marking paste, no preparation or follow-up is required when using a fiber laser. Achieve uniform and precise results even with fine details. Different effects like rich black or white color can be obtained using certain parameter settings. Our laser engravers for metal provide durable, counterfeit-proof depth to metal, ideal for productivity and quality. When marking metal, expand your possibilities using a MOPA laser as you can mark, for instance, (anodized) aluminum in black or create reproducible colors on steel.

Once you have chosen the right tool, the next key is to mount it correctly. If you’re having trouble investing in a high-performance cutter, using a universal chuck can reduce the benefits the tool offers. Side lock and ER collets are suitable for general milling but should be avoided when machining hardened steel.

Most standard grades of indexable tools can easily machine materials up to 45 HRc. When you start developing plastics with hardnesses above 50 HRc, most indexable inserts fail because they are not hard enough and have the wrong cutting-edge geometry. E.g., standard interchangeable 90-degree APMT/APKT cutters are useless for milling hard steel – the edge is too weak for high feed and shallow depth of cut. The ideal indexing tool for hardened steels is a high feed milling system such as Korloy HRM Double or HFM High Feed Milling. They feature a shallow depth of cut (0.3-1.6 mm), but operate at aggressive feed rates, ideal for hardened steel milling (>1.2 mm per revolution). Excellent grades for hardened steel are PC2005, PC2010, or PC2015, with a flat plate (no breaker) that can be machined to HRC 65.

Now that you have the perfect set of hardened steels, you need to think about how to use them – this will cultivate your success. In milling, especially in high-speed machining of hardened steels, the key to tool life and product quality is maintaining a constant chip load on the cutting edge. It is therefore worth using a higher cutting speed when turning hard materials and for low-alloy steels. The chip load is equal to the feed divided by the spindle speed multiplied by the number of cutting edges. It’s worth knowing that they vary widely; if it’s too low or too high, the tool will wear prematurely, bite or break. Many fast cuts and shallow feeds are the best way to ensure a high-quality product. Keep in mind, however, that in the cutting zone of stainless steel, there may be times when separate milling recommendations are worth implementing. Classical stainless steel will have different resistance and martensitic stainless steel will have different resistance. This is worth bearing in mind in order to avoid edge chipping. We hope that the machining hardened steels or milling hardened steels will no longer be a major problem for you.

This is one of the favorite chucks of many operators! Not only does it limit runout to 3 microns and balance to 25,000 rpm, but the hydraulic chuck has the added benefit of dampening tool vibration. On long-length equipment, it gives an advantage over a reversed handle by significantly reducing vibration. It also allows quick tool changes on the machine, and the clamping force increases as the temperature increases! Also available with the YG long-neck thermal handle (6 mm wall thickness) or the WTE HPH narrow handle (3 mm wall thickness).

Balanced – although they may be factory balanced to 15,000 rpm or more, this is not the case when installed with collets and tooling, Runout – runout up to 10 microns at a tool length of 3xD. However, if the length is 8xD, it will increase to 50 microns. For a 5 mm tool, this is a huge number, causing vibration of the tool and workpiece. When machining hard materials with equally hard equipment, these can lead to premature wear and poor reliability.

When milling HRc 50-70 hardened steel, it is not possible to use standard substrates made of carbide particles. Not only is the workpiece very hard, but dry working is often used to reduce heat fluctuations on the tool. For this purpose, you need devices containing the highest quality carbides, such as ultra-fine-grained (e.g., YG-1 X-Power) or nano-grained (e.g., YG-1 X5070). These grades are denser and therefore more resistant to wear and high temperatures, making them ideal for crush-hardened steels. In contrast, hard/ordinary carbide or high-speed steel wears out rather quickly due to the extreme heat generated.

Nevertheless, this method of processing hardened steel is one of the most difficult machining operations. For a successful project, it is necessary to understand several parameters that affect the entire machining process. Any flaw can lead to cutting errors and even permanent machine failure. It is necessary to know how to handle induction-hardened steels, what characterizes isothermally hardened ductile iron, and what the main problems are with low-carbon steels. No cutting tool engineering magazine will give you as much knowledge as practice and this article. Therefore, this article aims to explain some of the key factors to consider when implementing CNC milling technology for hardened steel machining in your facility.

Yes, you can laser engrave metals using a fiber laser without consumables. With a CO2 laser machine you can engrave metals with the help of a laser marking spray.

Products and parts made from hardened steel are common in many industries, including automotive, military and defense, medical, electronics, and semiconductors. The material is characterized by superior strength and hardness and is ideal for use in a variety of machinery and equipment components. However, the process of micromilling hardened tool steels is not simple. Before starting it, several factors must be taken into account, including ceramic inserts, cutting tools, machining parameters, and alloy additive content. Here are examples of hard milling solutions:

Tool life is longer when milling or turning hardened steel and is more consistent dry (i.e., without coolant). For most engineers, this defies logic, because in college they were told that the more lubricant, the better. However, hardened steel devices such as the X5070, for example, have coatings that can withstand much higher temperatures than those produced by dry cutting tool. Applying coolant to the tool can cause micro-cracking of the coating, which can in turn lead to easier deterioration and faster wear. This is similar to pouring cold water on a hot glass – it too can break, or more specifically, crack. With dry machining, you can usually achieve durability of at least 40%.

When it comes to metal engraving, aluminum is widely favored for its versatility. Stainless steel, on the other hand, is valued for its superior resistance to corrosion, mechanical stress, chemicals and temperature fluctuations. Trotec materials are meticulously tested to ensure they meet the highest standards of quality and performance.

Heat shrink sleeves are ideal for crush-hardened steel, with excellent concentricity and precise 3-micron runout to help maintain balance at high cutting speeds. Long-length tools perform particularly well in heat shrink chucks, with the added advantage of a narrow neck and small wall thickness, making them ideal for pocket machining where a narrow chuck is required.

Metal laser engravers guarantee thorough traceability of safety-relevant components, essential in automotive manufacturing. Achieving optimal readability of data matrix codes and alphanumeric markings is pivotal for compliance and quality assurance.

CNC milling is currently one of the most versatile heat treatment processes. Not only can it be used to produce parts that take days or weeks using traditional methods, but it can also be used to produce parts that would be impossible to create using other methods. Among several CNC milling techniques, micro milling is the latest development in the metalworking industry and is mainly used to harden steel. Compared to the conventional process, micro milling offers great advantages when developing hardened steel, especially in terms of surface finish and dimensional accuracy.

The best technology for marking steel components is a fiber laser. With a fiber laser you can permanently mark metals without consumables. Therefore, this technology is more cost-effective than other methods.

The purchase price for a laser engraver for metal starts at approx. 9,000 euros. Costs can vary greatly depending on the work area and laser power. We’d be happy to advise you on choosing the right laser engraver for marking metals.

The most versatile and economical tool holders are Korloy GSK or Cutwel HP3 ultra-thin bushings. With a runout of 5 microns, they feature a slim nut design and greater clamping force, far superior to ER collets. GSKs are designed with a taper angle of 8 degrees (compared to 16 degrees for ER collets). This eliminates the deflection and vibration typical of ER collets. It is highly recommended to use the Korloy GSK chuck in combination with the YG-1 hydraulic chuck for larger diameter tools.

A tool’s coating can have a huge impact on its performance. Standard TiAlN or TiCN coatings can withstand temperatures up to 800°C and wear out quickly when machining hardened steel. Specifically for this problem, YG-1 has developed a customized Y1200 blue coating, which can be found in X5070 tools. It has a very high-temperature resistance of up to 1200°C! The combination of this coating and nano-grained carbide means that our X5070 tools can machine high hardness steels up to 70 HRc at extremely high speeds and feeds with incredible durability! X5070 machines can be too hard, and tool life can be uneven when configured with older machines, machines with slower spindle speeds, or those subject to wear or vibration. In this case, a tool with ultra-fine particles, such as the YG-1 X-Power cutter, would be more suitable. It is more forgiving and can operate at lower cutting tool speeds due to the hardness of the carbide substrate.

The laser technology enables metal marking with different methods: Annealing marking, engraving and removing. During annealing the heat output leads to local change in the structure of metal, resulting in recoloring of the metal and the surface remains undamaged and clean. Engraving leads to a vaporization of the material. These inscriptions have a long life and are extremely abrasion resistant. When removing the top layer is removed with high speed by the laser, achieving vast contrast markings.
