Actuator Requirements For 7th Axis Robotics
Adding a seventh axis to your six-axis robotic system can be beneficial in a number of ways. Your work envelope is expanded, allowing the use of smaller, less-expensive robots. Parts can also be transferred to multiple workstations at greater distances, and more machines and processes are able to be serviced with one robot, which reduces costs.
Playbook: Linear Bearing Applications
In many industrial applications, linear bearings can fail prematurely due to misalignment of the bearing rails and moving elements, inadequate lubrication of the bearing’s unsealed components or contamination of the bearing rails and raceways. Rollon has developed an alternative bearing solution that meets these design challenges and more, offering alignment and contamination resistance, lifelong lubrication and installation cost effectiveness.
Playbook: Avoiding Linear Bearing Failure
When linear bearing systems fail prematurely, the reason almost always involves an overlooked application error.
Coating Considerations: When and Where to Use Electroless Nickel Plating
Deciding if it makes sense to apply a protective coating such as nickel to your linear motion components depends on several factors. Perhaps most important is the work environment your motion assembly will operate in—and whether or not your assembly must stand up to significant corrosion or wear factors. For high-performance motion control applications such as those found in the aerospace, semiconductor, medical, pharmaceutical, and food and beverage industries, investing in electroless nickel (EN) plating on your precision bearing assemblies will help extend component lifetimes.
When to Choose Compact Rail versus Profiled Rail for Reliable Linear Motion
Profiled rail, also known as monorail or ball rail, is a tried and true linear guide system that incorporates small recirculating balls to satisfy tight positioning accuracy requirements. Often used in high-precision motion applications such as machine tools, these guides can achieve repeatability at the micron scale if correctly specified, installed and maintained. However, this level of precision can be both costly and unnecessary depending on the application.
How To Select The Right Drive Train
When choosing a linear actuator, it’s important to figure out which drive train is best for your application.
Safety-Stroke Improves Actuator Design
When sizing and selecting a linear actuator, you want to start by figuring out how much safety-stroke your application requires. Overlooking safety-stroke early on can lead to design flaws or rapid actuator deterioration. Let’s take a look at safety-stroke and why it’s an important part of the decision-making process.
Linear Motion For Robotic Handling in Automated Warehouses
When designing and configuring an automated warehouse, you want to keep the system as light and compact as possible. Depending on the size of your load, there are two common types of automated warehouses: In lighter applications, aluminum structures can handle loads up to 100 kilograms, while steel structures are good for heavier loads more than 100 kilograms.
Reduce Engineering Difficulties With Cartesian Robot Systems
Even if you start with a basic setup, gantry systems often require more than 100 hours of engineering activity, including specifying dozens of parts across many vendors. With countless failure points and a multitude of suppliers, it’s hard to know who to call when something goes wrong. Generally, the end user calls the system integrator or distributor, hoping for adequate post-sale technical support and troubleshooting.
Robust Actuators Enable Reliable, Repeatable Motion
Since actuators serve as the workhorse of so many applications, they must be reliable. When specifying a Cartesian robot system, the overall quality of your actuator is essential. And picking an actuator with rigid linear guides and heavy-duty ball screws can make all the difference.
Understanding Precision In Linear Motion Applications
Every linear application, from simple pick-and-place to circuit board printing, requires some level of precision. This concept, one of the most vital in the world of linear motion, is best understood when broken into two separate terms: repeatability and accuracy.
Tips For Switching Out Linear Guide Profile Rails
Sometimes, design engineers need a new linear guide profile rail for shorter lead times, lower costs and better customer service. And while manufacturers may have similar interchangeable products, taking a closer look will make sure you get the same high-quality performance as your original model.
