What Running Standard Bots Taught Us About Machine Tending
What Running Standard Bots on Our Own Floor Taught Us About Automated Machine Tending
What does it take to make robotic machine tending work in a real CNC shop? Drawing on our experience running Standard Bots on our own production floor, we share four practical lessons about integration, operator training, choosing the right applications, and supporting automation after installation.
Most shops don’t have a capacity problem. They have a people problem that looks like a capacity problem.
The machines are there. The work is there. What’s missing is someone to stand at the spindle at 2 a.m. loading blanks and pulling finished parts. Hiring for that is hard, and asking a skilled machinist to do it is a waste of their skill.
That’s the gap robotic machine tending fills. We know, because we run it on our own floor in Ramsey, Minnesota, making real customer parts every day. Here’s what that experience has taught us, and what it means if you’re thinking about automating your CNC machines.
What Machine Tending Actually Does
Machine tending is simple to describe. A robot loads raw material into your CNC machine, waits for the cycle, pulls the finished part, and loads the next one. It does the repetitive work at the machine so your people can do the work that needs judgment.
The result is more spindle hours from equipment you already own. A machine that used to sit idle after the first shift can keep cutting into the second and third. It’s the difference between capability and capacity: having the right machines is one thing, keeping them running is another.
Lesson 1: The Robot Is the Easy Part
The arm itself is impressive. The Standard Bots Core we run is a six-axis robot with an 18 kg payload, 1.3 m reach, and ±0.025 mm repeatability. But the arm isn’t what makes a cell work.
A successful machine tending cell depends on more than the robot arm. The surrounding integration matters just as much:
- Gripper: Designed to securely handle the parts you’re machining.
- Vise actuator: Automates clamping and unclamping during the machining cycle.
- Door opener: Allows the robot to access the machine without an operator.
- PLC integration: Coordinates communication between the robot and CNC machine.
Get those right and the cell runs. Get them wrong and you own an expensive arm that waits for an operator.
That’s why every package on our automation page is built around the same Core arm. What changes is how much of the surrounding integration we handle for you.
Lesson 2: Your Team Doesn’t Need to Be Roboticists
The old knock on industrial robots was that you needed a robotics engineer to run one. That’s less true than it used to be. Standard Bots uses a touchscreen, no-code interface built to make programming and operation approachable for the team you already have.
The real skill isn’t programming the robot. It’s understanding the part, the fixture, and the cycle. That’s machinist knowledge, and your team already has it. We train your operators during installation and stay available after handoff.
Lesson 3: Start With a Process You’ve Already Proven
The best first automation project isn’t your hardest job. It’s one that already works well by hand. Look for:
- A proven process: A job you’ve already run successfully.
- A repeatable setup: Consistent workholding and a stable machining cycle.
- A familiar part: Something your team understands and knows how to produce reliably.
A robot is great at doing the same thing the same way. It can’t fix a process that isn’t stable yet.
Compatibility matters too. Whether a robot can tend a given machine depends on its controls, how it communicates, and how its door operates. Most CNC machines can be automated, but the details decide how. Send us your machine make and model and we’ll tell you what it takes.
Lesson 4: What Happens After Install Matters Most
Anyone can sell you a robot. The harder question is who helps when your part mix changes, a new job needs a different gripper, or a cycle needs tuning. Because we run these systems in production ourselves, we understand the challenges that come with keeping them running as jobs and requirements change.
That’s the difference between a distributor and a partner. We’re an authorized Standard Bots distributor for the Upper Midwest, but we don’t stop at the sale. We distribute, install, integrate, and support the cell, as machinists who use the same equipment every day.
Proof on the Floor
Our showroom is a shop floor. The automation systems we recommend aren’t just demonstrations. They’re part of the equipment we use to manufacture customer parts.
Standard Bots featured Path as a machine tending case study at IMTS 2026, and we filmed a video with them right on our production floor, alongside the parts we machine for customers.
Four Ways to Start
We offer four packages so you can match the investment to what your shop can handle in-house.
| Package | What you get | Starting at |
| Path to Start | Standard Bots Core arm only; you integrate | $39,500 |
| Path to Production | Arm, controller, gripper, and vise actuator | $49,900 |
| Path to Autonomy | Complete cell with door opener, PLC, pedestal, and 3-day on-site install | $98,000 |
| Path to Scale | Custom-engineered cell for multi-machine or complex applications | Custom quote |
Installation travel and expenses are not included. Full details on each tier are on the automation page.
Robotic Machine Tending FAQs
Can robotic machine tending work with my existing CNC machine?
In many cases, yes. Compatibility depends on the machine’s controls, communication capabilities, door configuration, and workholding setup. Some machines are easier to integrate than others, and additional hardware may be needed to automate certain functions. We can review your machine make and model to determine what’s required.
What types of CNC jobs are best suited for robotic machine tending?
Start with parts that have a stable machining process, consistent workholding, and predictable cycle times. Jobs with repetitive loading and unloading are often good candidates, particularly when the machine could continue running beyond staffed hours. More complex applications can also be automated, but a proven process is usually the best place to begin.
Do I need a robotics engineer to operate a Standard Bots system?
Not necessarily. Standard Bots uses a touchscreen, no-code interface designed to make robot programming and operation more accessible. Your machinists already understand the parts, fixtures, and machining cycles involved. With the right training, they can apply that knowledge to operating the cell. Path provides operator training during installation and ongoing support afterward.
What affects the cost of a robotic machine tending system?
The robot arm is only part of the investment. Grippers, workholding automation, machine-door access, controls integration, and installation all affect the total cost. A shop that can handle its own integration may need a different package than one looking for a complete, installed cell. That’s why Path offers several options, from the Core arm to custom-engineered systems.
Can robotic machine tending run CNC machines unattended overnight?
It can, provided the entire machining process is ready for unattended operation. The robot handles loading and unloading, but the CNC machine still needs reliable tooling, chip management, coolant, workholding, and appropriate fault handling. A stable process and the right safeguards are essential before extending production into unattended shifts.
Automation That Works for Your People
Automation isn’t about replacing your machinists. It’s about giving them a partner that doesn’t get tired, so the people you worked hard to hire spend their time on setups, programming, and quality.
If you’re running two to four machines and want unattended second- and third-shift capacity without hiring a robotics specialist, we can help you get there.
