Top Questions to Ask When Buying a Sanding Machine

Does it sand edges and break corners - or just faces?

This is the most important question you can ask. Most robotic sanding systems only sand flat faces, leaving edges and corners for manual operators. That means you're still hiring sanders and still dealing with inconsistency. The Stolbek Cosmo SC sands faces, edges, AND breaks corners in one automated cycle - no manual touch-up required. Ask any vendor to demonstrate edge sanding live. If they can't, you're buying partial automation.

Is it a turnkey system or a custom integration project?

Some vendors sell a robot arm and leave integration to you - dust collection, programming, safety enclosures, tooling, and support are all separate. Stolbek delivers complete, turnkey systems. Everything arrives ready to run: robot, controller, sanding tools, dust collection, safety enclosure, and operator training. No third-party integrator required.

Was it designed specifically for woodworking?

Many robotic sanding systems are adapted from metal or automotive applications. Wood behaves differently - grain direction matters, dust management is critical, and surface finish standards are unique. Stolbek was founded by woodworkers and every system is purpose-built for wood sanding. The difference shows in finish quality, dust handling, and real-world reliability.

What is the total cost of ownership - not just the purchase price?

The sticker price of the machine is only part of the equation. Factor in: integration costs, programming time, consumable costs, maintenance frequency, operator training time, and ongoing support fees. Stolbek systems use standard abrasives (not proprietary consumables), include training, and offer remote diagnostics - keeping your total cost of ownership predictable and low.

What does the product ecosystem look like?

A single machine might solve today's problem. But what about tomorrow? Look for a vendor with a range of products that can scale with your shop. Stolbek offers five systems covering different production needs - from entry-level edge sanding with the Spin Bot to large-format panel sanding with the Cosmo XL. As your shop grows, your automation can grow with it.

How long does operator training take?

If the answer is 'weeks' or 'you'll need a programmer,' that's a red flag. Your operators are woodworkers, not software engineers. Stolbek systems use touchscreen controls with simple recipe-based programming. Most operators are running parts independently within hours of training - not weeks.

What kind of support do you get after the sale?

Robotics companies sometimes disappear after installation. Ask about ongoing support: response times, remote diagnostics, spare parts availability, and on-site service. Stolbek provides direct support from the people who designed and built your machine - not a call center. Remote diagnostics let us troubleshoot most issues without a site visit.

Can you talk to current customers?

Any vendor confident in their product will connect you with existing users. Ask to speak with shops similar to yours in size and production type. Stolbek customers consistently report reduced labor costs, improved quality, and faster throughput. Read their stories on our testimonials page or ask us for a direct reference.

What's the expected ROI timeline?

Automation is an investment. You should know exactly when it pays for itself. Most Stolbek customers see payback within 12-18 months based on labor savings alone - before factoring in quality improvements and reduced rework. Use our ROI calculator to model the numbers for your specific shop.

Who is behind the machine?

Is the company a robotics startup that's never been inside a cabinet shop? Or is it run by people who've actually stood at a sanding station? Stolbek was founded by woodworkers who got tired of the sanding problem and decided to solve it. Our team understands your shop because we came from your shop.

"Can it sand edges AND faces, or only faces?"

This is the most important question. Most robotic sanding systems only sand flat faces. That means your operators still manually sand every edge and break every corner. If the answer is "faces only," you're buying partial automation — not a complete solution. Stolbek is the only system that handles edges, corners, and faces in one turnkey cell.

"Is it turnkey, or does it require a system integrator?"

Turnkey means the machine ships complete and ready to run. No custom engineering. No third-party integrator designing your cell. No months of back-and-forth before you sand a single door. If the vendor says "we'll connect you with our integration partner," that's a red flag for timeline and cost.

"What robot brand does it use? What's the maintenance schedule?"

The robot is the core of the system. Ask specifically what brand, what model, what the maintenance intervals are, and what the expected service life is. Stolbek uses Yaskawa GP12 — industrial-grade, IP67 rated, 8 years maintenance-free on the arm. Learn more about Yaskawa robotics →

"How long does installation take? Will it require custom engineering?"

Stolbek installs in approximately four days — including calibration, training, and production refinement. If a vendor is quoting months of installation or custom engineering work, the system isn't turnkey.

"What consumables does it use? Can I order them directly?"

After the machine is installed, you need sandpaper, pads, and replacement parts. Ask whether the vendor sells consumables directly or whether you're sourcing third-party parts. Stolbek sells all consumables through the online Supplies portal.

"What does training look like? How quickly can my team run it?"

Ask for specifics. How many days of training? Who does the training — the vendor's team or a third party? How long before operators are running production independently? Stolbek trains operators during the 4-day installation. Most shops are running production by day two.

"What ongoing support is available?"

Ask about support channels, response times, and whether support is included or billed separately. Stolbek provides support via instant messaging, phone, and in-field service — from the people who actually build the machines.

Requires system integrator

This means the vendor sells a robot arm and a sanding attachment, but the complete cell — table, fixturing, safety, programming — is someone else's responsibility. You're buying a kit, not a solution. Expect months of custom engineering, significant additional cost, and a long path to production.

No edge sanding capability

If the system only sands faces, you still need manual edge sanders. That's not full automation. Ask directly and get a clear answer.

No consumables business

If the vendor doesn't sell sandpaper, pads, and replacement parts, they're a one-time equipment sale. They sell you the machine and move on. A vendor that sells consumables has an ongoing relationship with you and an incentive to keep your machine running.

Long lead times with no standard product

If every machine is a custom build, lead times stretch to 6-12+ months and the system arrives as a first-of-its-kind prototype. Standard products with proven installations mean faster delivery and a system refined across dozens of shops.

No customer references in your industry

If the vendor can't connect you with a cabinet shop, furniture manufacturer, or millwork producer who's running their system today, ask why. A proven vendor has happy customers who are willing to talk. See Stolbek's customer stories.
