Scanmaskin Scan Combiflex 650 Floor Grinder

Looking for a floor grinder with a smaller footprint that can still handle big commercial projects? Try the Scan Combiflex 650
It puts the torque on the floor – not on your hip!

Who should use the Scan Combiflex 650?

The Scan Combiflex 650 is a powerful concrete floor grinder that is ideal for commercial projects where high-productivity is a must, but a smaller footprint is needed.

This unit weighs in at 705 lbs, making it nearly twice as heavy at the Scan Combiflex 500PD. It gives you the extra weight and larger grinding path (26 inches) for improved productivity rates on a wide range of jobs, from small to large.

The Scan Combiflex 650 is great for grinding and polishing of concrete, terrazzo, and natural stone surfaces. But where this machine really shines is in paint, coating, and overlay removal applications.

Although conditions will vary greatly from job to job, most contractors have been pleased to report production rates of around 645 to 970 square feet per hour. 

Is it easy to use?

When it comes to using the machine, the controls couldn’t be simpler. Just press the green button to start the machine, and the red button to stop it.

The unit also features an emergency stop button as an extra precaution. The emergency stop button will remain depressed until the operator turns it slightly clockwise to pop it out.

Simple twist knobs control the direction and speed of the spinning heads. You can easily switch the direction of the grinding heads to ensure longer life and even wearing of your diamond tooling. This maximizes their use and saves money in the long run.  You can also adjust the speed between 350 to 1,100 RPMs, letting you dial in the perfect cutting rate.  (Single-phase model operates at 350-900 RPM).

The water inlet on the 650 also has a flow control valve, which lets you adjust the water flow to match the grinding needs of the job.

Don’t I need more horsepower?

When it comes to choosing a grinding machine, many contractors mistakenly think that horsepower is most important. Don’t be fooled.

Scanmaskin engineers discovered that most grinding equipment is terribly inefficient. They rely on tension belt systems that need to make up for the loss in power by having larger motors that produce more horsepower. But because of their inefficient design, all that extra power isn’t directed at the floor – it’s also directed at the operator who has to lean against the machine and fight it as it kicks and bucks.

Scanmaskin equipment features a highly efficient patented drive system that uses less horsepower but delivers more torque on the floor – not on your hip!

Why do you make such a big deal about the drive system and grinding heads?

The Scan Combiflex 650 features some unique engineering that sets it apart from other grinders on the market today.

This unit features a patented three-head planetary drive system. It uses a double-sided cog belt combined with a gear ring to create a counter-rotating planetary motion that allows the machine to grind a high speeds with heavier head pressure, resulting in increased productivity. Simply put: it’s superior engineering that delivers better results on every job.

The counter-rotating planetary drive system directs all the torque to the floor. Unlike other grinders that make you feel like you’re fighting a bucking bull, the 650 provides incredibly smooth operation. It’s so smooth, in fact, that you can set your coffee cup on the shroud and it won’t slosh or spill!

The 3-head planetary system holds up to 18 tools. Unlike other systems that require a screwdriver, Allen wrench, and hours of struggle to attach tooling, the Scan Combiflex lets you easily tap on and tap off your tools.

Another unique engineering element of the Scan Combiflex 650 is that the heads feature spring steel disks, not rubber flex systems like most other grinders on the market.

After thorough side-by-side testing, Scanmaskin engineers discovered that the spring steel disks were far superior to the traditional rubber flex systems found on most other grinders. They provide increased durability and better, more consistent grinding. They can be configured to increase or decrease head flexibility as well, something rubber flex discs can’t do.

Spring steel disks are perfect for any type of grinding application, from aggressive surface prep to providing that fine finishing polish.

What maintenance will this machine need?

The Scan Combiflex 650 is designed to not only be durable, but to also require very little daily maintenance. Scanmaskin machines are designed to work, not to be worked on.

You can expect less downtime and lower maintenance costs for the life of the machine.

Is it easy to transport?

The Scan Combiflex 650 has solid rubber wheels, so maneuvering the unit around the job site or up and down a ramp is a breeze.

How tough is this machine?

When we describe this machine as durable, we’re not exaggerating.

Unlike other units that feature plastic or fiberglass parts, the Scan Combiflex 650 is made from solid steel – right down to the dust shroud. This unit resists dents, chips, and cracks, ensuring that it far outlasts the competition.

What about dust control?

Dust can be a major issue for other systems when it comes to dry grinding applications, but not for Scanmaskin equipment. 

All Scanmaskin floor grinders feature a dust shroud made from solid steel. You won’t find duct tape on a Scan Combiflex unit. Unlike other grinders with shrouds made from plastic or fiberglass, our dust shrouds won’t chip or crack, and they do a far superior job of controlling dust and debris.

The Scan Combiflex 650 also has an adjustable thick rubber dust skirt, so you can position it flush against the floor, creating a better seal.

Lastly, the unit features dual vacuum ports for more efficient dust collection. The vacuum connection port is conveniently located in the back of the machine.

The combination of these features makes for virtually dust-free grinding and polishing. The result is a cleaner work area that takes less time to clean up and is safer for the operator and building occupants.
