Cutting Wheels

SUPER-CUT carbide and diamond finish cutting wheels are designed to create a clean and defined score of the glass.

Black Diamond Cutting Wheels

SUPER-CUT Black Diamond PCD cutting wheels are precision assembled to fit every cutting machine currently on the market. Durable and dependable, our Black Diamond cutting wheels offer the highest cut speed, score quality (reduced flake chips) and longest life available today.

Black Diamond cutting wheels solve a variety of production challenges (such as glass thickness breaking out, high compression surface and difficult shapes or edges) while lowering the cost of cutting. We stock wheels in angles of 134°–160° with wheel OD in standard 4.2 mm and 3.0 mm sizes.

TIP: For ceramic plates, try a 134° angle Black Diamond cutting wheel in the 3.0 mm size to enhance performance.

Carbide Cutting Wheels

For certain glass operations where a PCD cutting wheel is not suitable for short-run parts or a particular glass thickness, SUPER-CUT offers dependable, low-cost carbide cutting wheels. SUPER-CUT carbide cutting wheels are available pre-assembled or as separate components. Our pre-assembled wheel, axle and insert save valuable line operator assembly time, increasing your productivity.

In consumer product applications, the appearance of the visible ground edge is critical. This often requires a special profile with multiple radius, blended to a complex shape. SUPER-CUT EDM profiles will give you the exact shape you design. Learn more about our Wheel and Drill Reprofiling services.

SUPER-CUT diamond and metal bonds have the best wear rates in the industry. Our bonds hold the profile shape, improving tempering yields. Increase the number of redress in each wheel and lower your cost significantly.

Let SUPER-CUT custom design the glass profile for a superior ground edge, quick startup and high oven yields.

SUPER-CUT can design a custom OD exactly for your equipment and grinding needs with wheel OD as small as 25 mm and no restrictions on the OD of the grinding wheel.

Seaming Wheels

SUPER-CUT also offers special diamond/bond specifications and profiles for a seamed edge. Learn more about our Diamond Seaming Belts.

Diamond Wheel Redress

SUPER-CUT will restore your diamond wheel to its original condition at one of our 14 global redress centers using our NC Electrode Discharge Machining (EDM) process. We also offer special Quick Start wheel profiling for high-speed grinding with immediate startup and no ramp up, with excellent glass edge quality.

Diamond Drill Bits

SUPER-CUT offers a variety of drills that are custom engineered to your application and ready within two to four weeks.

Core Drills

Our one-piece straight core drills offer fast performance and amazing life, in sizes from 4 mm to 180 mm OD. In sizes under 25 mm, SUPER-CUT straight core drills have been known to drill more than 40,000 holes. SUPER-CUT can fit any drilling machine on the market today. Shank design will be selected to fit your equipment.

SUPER-CUT diamond core drills and seamers have been developed for use on high-performance CNC glass drilling machines with long series batch production. A complete range of SUPER-CUT designs and specifications are available to fit each machine:

Quick startup
Accurate hole size
Great hole quality
We can set the optimum spindle speed or design the drill bit to run at your required speed
High feed rates
Coolant type: coolant or water
Tool life that’s the best in the industry

Chamfer Drills: One-piece Design

SUPER-CUT’s one-piece chamfer drills are designed to drill and chamfer holes in a single cycle. The fixed core lengths are set for each glass thickness to provide optimum drill speed and hole quality. The one-piece core drill seamer is the most commonly used drill in glass today due to its ease of use and excellent hole quality, resulting in high glass yields in the tempering process. Consult a SUPER-CUT sales engineer for a size and specification recommendation.

Chamfer Drills: Two-piece Design

SUPER-CUT’s two-piece drill design allows you to match a core drill of your choice to the seamer, so the same OD drill can be used for multiple glass thicknesses. The seamer is precision designed for a tight fit to maintain hole quality. While the two-piece drill bit combo offers greater flexibility, it requires more in-house control by plant personnel during setup.

Shanks are available for any glass drilling machine: Bystronic, Bando, TAC, Forvet, Bentler, Schiatti, ADA, Glassline, SunTool, Intermac and more. For special or custom machines, SUPER-CUT can design a shank for your specific application.

Drills, Seamers and Routers

Need to finish a cut-out or shaped opening? SUPER-CUT has the seamer, pencil edge or router to give your finished product the exact look required for today’s stove top designs.

TIPS:

Are you cutting this shape with a water-jet? As a major abrasives company, SUPER-CUT can offer you the garnet abrasive required to cut glass or ceramics.

Are you interested in improving oven yields? Try a SUPER-CUT chamfer drill bit instead of a straight core drill bit. We have live case studies of improving oven yields up to 12%!

Dressing Sticks

SUPER-CUT dressing sticks are used on diamond tools to sharpen or re-expose diamonds and optimize glass edge quality and tool feed speed. Proper wheel and drill dressing will reduce chipping and eliminate breakage and burns during glass fabrication.

TIP: SUPER-CUT carries longer, 230 mm dressing sticks made especially for hand-dressing your diamond grinding wheel.

Coolants

SUPER-CUT offers a variety of leading coolant products with chemistries specially designed to complement our diamond wheels and drills. We offer everything you need to keep your glass process running smoothly — from complete cooling system management to coolants and lubricant additives.

Our product line includes:

Cutting and scoring oils
Grinding coolants
Conveyor and chain lubricants for furnaces
Washer fluids
Maintenance oils
Coolants and cutting fluids for tool rooms
Coolant field samples and analysis

Cutting/Scoring Oils

Cutting oil is used to score glass for breakout. The oil fills the score and prevents the glass from re-healing, allowing a clean, defect-free separation of the glass part from the cullet trim.

Some of the primary benefits of our cutting oil are:

Clean breakout of scored glass to prevent edge chips
Increased cutting machine uptime
Lower tooling cost
Reduced changeover time and machine adjustment

Careful use of cutting oil is required to ensure compatibility with take-away belts and seals in the cutting equipment. Using the wrong oil will create a fire hazard in your plant. Since the oil is washed into the coolant system, take care that the cutting oil does not become a contaminant in your grinding coolant or glass washer.

Four types of scoring oils are available:

Hybrid (the most common oil used)
Vanishing
Soluble (the most common source of contamination in your washer or coolant recovery system)
Straight

Ask your SUPER-CUT sales engineer to help you select the perfect cutting oil to meet your glass cutting needs.

Grinding Coolants

Years of R&D development have generated significant new synthetic coolant products for glass operations. Coolant is designed as a one-part system used primarily in centrifuge systems, or a two-part system with a secondary flocculant additive for settling systems.

SUPER-CUT supplies a full range of high-quality coolants for glass grinding that:

Improve wheel and drill life by 40%
Increase line speed
Enhance edge quality
Reduce energy consumption
Increase oven yields and eliminate glass loss due to burns or microfracture chips
Control foam
Prevent coolant guard and line plugging, with additives to prevent glass fines from clumping or hardening
Inhibit biological growth
Protect equipment from rust
Eliminate water spots on the glass

We also offer a full line of additives, including flocculants, coagulants, defoamers, rust inhibitors and bactericides.

Your SUPER-CUT sales engineer can evaluate your glass grinding process and recommend the best coolant for your operation.
