When selecting a precision linear stage or positioning stage, it's easy to focus on the headline specs: travel, load capacity, and accuracy. While these are essential, they only tell part of the story. The most common and costly purchasing mistakes occur when buyers fail to ask the deeper questions—the ones that reveal a stage’s true performance, long-term value, and the quality of the company behind it.
At ABTech, we are more than a supplier; we are an engineering partner dedicated to your success. That's why we're sharing the critical questions our own engineers would ask. These insights will help you distinguish between a good-enough solution and a perfect one, ensuring your application reaches its full potential.
Part 1: Questions About Real-World Performance
- "What are the stage's geometric accuracies (pitch, roll, yaw), and can you provide a metrology report?"
The ABTech Answer: Positional accuracy is only half the story. In sensitive applications such as optical scanning, metrology, and nanopositioning, even tiny angular errors—specifically, pitch, roll, and yaw—can be devastating. That’s why we manufacture our high-precision linear stages, particularly our air-bearing models, to deliver sub-arcsecond geometric tolerances. This isn't just a claim; we provide comprehensive metrology data with our products to prove it, ensuring you get the true, verifiable precision your application demands.
- "How will this stage's performance change in my specific operating environment?"
The ABTech Answer: A stage's performance can be dramatically affected by its operating environment. Thermal fluctuations, for instance, can cause materials to expand and contract, destroying accuracy. To combat this, we engineer our stages with exceptionally stable materials, offering Hardened Stainless Steel, granite and/or ceramic on our air bearing linear stages. We also have deep experience building stages from vacuum-compatible materials that won't outgas, ensuring flawless performance whether your application is in a lab, a factory, or in orbit.
- "What is the stage's dynamic performance, specifically settling time and velocity ripple?"
The ABTech Answer: For high-throughput applications like semiconductor scanning, it’s not just about speed—it’s about how quickly a stage can move and stabilize. A slow settling time creates a bottleneck that kills efficiency. Our air-bearing linear stages and oil hydrostatic linear stages are designed for superior dynamic performance. By using a non-contacting linear bearing, they provide inherently smooth, frictionless motion. When we integrate them with high-performance motors and controls, this minimizes velocity ripple and settling time, directly maximizing your throughput.
Part 2: Questions About Long-Term Value & Reliability
- "What are the maintenance requirements and expected operational lifetime?"
The ABTech Answer: The total cost of ownership goes far beyond the initial purchase price. A stage that requires frequent downtime for lubrication or adjustment is a hidden drain on productivity. Our non-contacting air-bearing and oil hydrostatic linear stages are built for the long haul. As our website states, because they have "no mechanical contacting parts to wear, or create drag," they offer decades of reliable, maintenance-free motion. This is a crucial advantage that lowers your total cost and ensures your system is always running.
- "How will this stage integrate with my existing motors, controllers, and software?"
The ABTech Answer: A linear translation stage is not an island; it's a critical component in larger motion control systems, and ensuring seamless integration is vital to avoid project delays. Why choose us? Because we eliminate the guesswork. We provide complete, turnkey precision motion systems, expertly configuring the stage, motor, and high-resolution encoder to work together perfectly. Our high-performance linear motors and encoders are "integrated seamlessly with application-specific controls," delivering a solution that’s ready to perform right out of the box.
Part 3: Questions About Partnership & Customization
- "What is your process for handling customization if a standard product isn't a perfect fit?"
The ABTech Answer: Many of today’s most advanced applications have unique constraints, from tight spaces to the need for specific mounting holes. This is where you determine whether a supplier is a rigid catalog seller or a true engineering partner. We are specialists in custom solutions. Our collaborative process involves working directly with your engineers to modify existing designs or create entirely new precision motion components—from the base material to the specific precision linear actuator used—from the ground up. We build the exact solution you need, not just the one we have on the shelf.
- "What level of post-sale engineering support can I expect?"
The ABTech Answer: A supplier's commitment to your long-term success is revealed by their post-sale support. Our partnership doesn't end at the shipping dock. The same engineering team that designed and built your stage is available to help with integration, troubleshooting, and ensuring your system performs optimally for years to come. We are your partner throughout the entire product lifecycle.
