In today's stone fabrication industry, speed and polish matter.

Consistency matters.

But nothing matters more than producing a flawless polished edge that keeps customers happy and protects your reputation.

Whether you're running a Park Industries Fastback, Comandulli, Marmo Meccanica, Denver, Bavelloni, or another automatic edge polishing machine, your polishing system directly impacts production speed, tooling costs, and final finish quality.

That's why more fabrication shops are making the switch to the Alpha Twincur GEM-V 6" Polishing System.

What Is the Alpha GEM-V System?

The Alpha Twincur GEM-V is a complete edge polishing system designed specifically for automatic edge polishing machines.

Unlike many polishing systems that require different wheel sets for different materials, the GEM-V system was engineered as a universal solution capable of polishing:

• Granite
• Quartz
• Quartzite
• Marble
• Limestone
• Porcelain
• Dekton®
• Sintered Stone
• Engineered Stone
• Concrete

The system is available in both 5" and 6" diameters, but the 6" version has become especially popular among high-production fabrication shops operating automatic edge polishers. Alpha describes the GEM-V as a hook-and-loop system for straight and beveled edges that produces fast, consistent results and includes the TSUYA final polishing wheel for maximum shine.

Why Edge Machine Operators Love GEM-V

Ask any experienced fabrication shop owner what they want from a polishing system and you'll usually hear the same answers:

• Long life
• Consistent polish
• Easy wheel changes
• Less downtime
• Better edge quality

The GEM-V system checks every box.

Unlike traditional snail-lock systems, GEM-V utilizes hook-and-loop backing, allowing wheel changes without wrenches. This reduces downtime and speeds up maintenance while keeping production moving.

For fabrication shops polishing hundreds or thousands of linear feet every week, those saved minutes add up quickly.

The 6" GEM-V Sequence

The complete 6" GEM-V polishing sequence consists of:

• 50 Grit
• 100 Grit
• 200 Grit
• 500 Grit
• 1000 Grit
• 2000 Grit
• 3000 Grit
• TSUYA Final Polish

Alpha offers the complete progression in 6" diameter with a maximum operating speed of 2,000 RPM.

Each wheel is designed to work seamlessly with the next step in the process, creating a highly refined finish while maintaining production efficiency.

Why the TSUYA Pad Changed Everything

If there is one wheel that gets talked about more than any other in the GEM-V lineup, it's TSUYA.

The TSUYA final polishing pad was developed specifically to create the highest possible shine after the 3000 grit stage. Alpha and multiple distributors highlight its ability to achieve monument-quality gloss, even on difficult materials such as Absolute Black granite.

Many fabricators describe TSUYA as the difference between:

A good polish...

and

A "wow" polish.

Benefits include:

• Increased gloss
• Improved edge clarity
• Better reflection
• Enhanced color depth
• Reduced haze
• Premium showroom finish

For shops fabricating luxury kitchens and high-end projects, TSUYA has become the secret weapon for creating edges that stand out.

Why Fastback Owners Frequently Choose GEM-V

Park Industries Fastback owners are constantly looking for ways to maximize machine uptime while maintaining premium edge quality.

The GEM-V system has become a popular choice because it delivers:

• Consistent polishing performance
• Long wheel life
• Fast wheel changes
• Compatibility with a wide range of materials
• Reliable results on straight and beveled edges

The ability to run one polishing system across granite, quartz, porcelain, and sintered materials helps reduce tooling inventory and simplifies machine setup. Alpha specifically markets GEM-V as a single polishing system for multiple stone types, including sintered slabs.

One System for Modern Materials

Fabrication has changed dramatically over the last decade.

Today's shops are no longer polishing only granite.

Now they're processing:

• Quartz
• Porcelain
• Dekton®
• Ultra-compact surfaces
• Sintered stone
• Quartzite

Managing separate polishing systems for every material can become expensive and complicated.

The GEM-V system was designed to simplify that process by allowing shops to use one polishing platform across a broad range of materials. It is also widely promoted as a recommended polishing solution for Dekton® applications.

How GEM-V Helps Reduce Operating Costs

Many shops focus only on wheel pricing.

The real cost is production cost.

Factors that impact profitability include:

• Wheel life
• Downtime
• Labor efficiency
• Machine utilization
• Finish quality
• Rework

Because GEM-V is known for producing fast, consistent results while offering long service life, many fabrication shops view it as a system that helps lower overall polishing costs rather than simply comparing wheel prices.

Which GEM-V Wheels Should You Keep in Stock?

If you're running an edge machine every day, keeping critical replacement positions in inventory can prevent costly downtime.

Most shops keep extras of:

• 50 Grit
• 100 Grit
• 200 Grit
• 500 Grit
• TSUYA

These positions tend to be the most important for maintaining uninterrupted production.
