The Hardest Metals to Machine: How Industrial Robot Machining Is Breaking Boundaries

For many years, machining difficult steels has actually been a considerable obstacle for making automation. With brand-new robotic machining systems, machining difficult products is currently feasible.

Hard steel, toughened up steel, titanium, and various other high-strength products are important in markets such as aerospace, auto, and power.

Nonetheless, the actual toughness that makes these products useful additionally provides a trouble for automation. Generally, they might just be managed by expert, inflexible CNC makers– a machining robotic would certainly have no possibility!

However, this is transforming …

In this post, we’ll check out just how brand-new high-stiffness robotics are redefining what is feasible with robot machining. We’ll cover what makes sure products challenging to reduce and just how robotics are currently satisfying the obstacle.

From Easy to Extreme: Why Hard Metals Obstacle Some Machining Equipment

The initial step to genuinely comprehending the capacity of robot machining is to comprehend the products themselves.

Machinability is a procedure of just how conveniently a product can be reduced. It relies on an equilibrium of residential or commercial properties consisting of firmness, ductility, durability, and thermal conductivity.

Some products are notoriously very easy to deal with, such as light weight aluminum. Others are so hard, heat-resistant, or rough that also a little job can use via tooling or undercut a machining configuration.

Easy to Maker Steels

In the past, robot machining was just durable for soft, easy-to-machine products because of the conformity of commercial robotic joints.

Instances of “pleasant” steels that are very easy to equipment consist of:

• Light Weight Aluminum– This stalwart of production is popular for its superb thermal conductivity and simplicity of reducing.
• Light steel– This is solid sufficient for framework, however still workable for machining.
• Brass Made use of in less jobs than the previous 2, this uses foreseeable chip development and marginal device wear.

Difficult to Maker Steels

Newer robot machining systems– such as those from Autonox that we saw at Automatica 2025— are currently efficient in machining harder products that were formerly difficult.

Instances of difficult to equipment steels consist of:

• Hard and toughened up steel– These steels are dealt with to stand up to contortion, placing even more stress on reducing devices and therefore calling for stiffer machining devices.
• Titanium alloys– These are valued for their strength-to-weight proportion however well-known for inadequate warm dissipation.
• Inconel and nickel-based superalloys– These expert and often exclusive products can maintain their firmness also at heated temperature levels.

While robot machining is still restricted with these products, the brand-new systems from Autonox that can equipment toughened up steel, mark a modification. Robot machining is currently a practical choice for machining difficult steels.

The Increasing Duty of Robotics in Industrial Machining

At RoboDK, we have actually been complying with the advancement of robot machining for several years. Our leading robot programming software is made use of by numerous makers seeking to make their procedures much more adaptable with robotics, consisting of for machining applications.

Robotics supply fringe benefits for machining, consisting of assistance for bigger work areas, even more complicated geometries, and better versatility for manufacturing circulation modifications.

In the last few years, a brand-new generation of high-stiffness commercial robotics has actually developed a change in commercial machining. Procedures that formerly would just have actually been feasible with a standard CNC equipment are currently attainable with robotics.

Several factors are driving this development consisting of:

• Boosted mechanical tightness of robot manipulators.
• Dynamic settlement of resonances in robotic controllers and control software program.
• Accuracy calibration of robot manipulators.
• High-precision encoders that permit even more exact joint control and secure reducing courses.
• Robotic shows devices for robot machining like our [set of free add-ons for optimizing applications][ADDON] like robot machining.

This mix of aspects permits robotics to deal with more challenging products with better precision and control than in the past. While still much less inflexible than standard CNC makers, the void in between the modern technologies is minimizing.

The Trouble: Taking Care Of the Forces Behind Hard-Material Machining

The significant obstacle when machining difficult products is handling the extreme pressures on the machining device.

In easy terms, as the robotic’s machining device lowers on the product, the product presses back with an equivalent pressure. Also a percentage of conformity in the robotic device can create resonances, causing machining errors.

There are 2 methods for handling these resonances:

1. Easy: Robotic System Style– The new age of commercial robotics is being made with high-stiffness mechanical frameworks that can hold up against high pressures.
2. Energetic: Control and Programs– Both low-level joint control and top-level shows integrate to proactively neutralize resonances when they happen.

A robot system ideal for machining difficult products will certainly integrate both methods to make sure exact machining.

Robotic Calibration: The Trump Card in Machining Hard Metals

What actions can you require to enhance the precision of your robotic machining system?

One variable that individuals frequently ignore is calibration.

When configuring a robotic to equipment difficult steels, also the tiniest mistake in a robotic’s kinematic design can equate right into noticeable surface area mistakes. This is where robotic calibration ends up being the trump card.

Calibration includes recognizing and remedying geometric inconsistencies in between the robotic’s electronic design and its real-world actions. By straightening these specifications, you make sure the device adheres to the designated course with optimum accuracy– a critical action when resistances are limited and products are ruthless.

We provide a series of Robot Calibration solutions to assist guarantee your robotics carry out at their outright finest.

Robotic Machining: Redefining What’s Feasible With Hard Products

The capability to equipment solidified steels with robotics notes a specifying minute in commercial automation. What was as soon as taken into consideration the domain name of just one of the most inflexible CNC makers is currently progressively feasible with robotics.

By incorporating the most up to date wave of high-stiffness robot devices with the appropriate shows devices, robotic calibration, and progressed simulation, you can gain from the versatility and scalability that robot systems supply.
