Diamond Tooling for Grinding and Cutting Thin Glass

SUPER-CUT diamond tooling products deliver superior grinding and cutting performance in demanding thin glass processing applications, from ultra-thin glass for consumer electronics (phones, tablets, laptops and wearable devices) to optical components. SUPER-CUT’s total system solutions include cutting tools, grinding wheels and lubricants specially designed to meet the unique edge quality and startup challenges of thin glass fabrication.

While the rising demand for thin glass offers incredible potential and new applications, thin glass is extremely challenging to fabricate. Precise cutting and grinding is required to ensure a high-quality edge while avoiding breakage. SUPER-CUT’s high-performance wheels and drills are engineered for consistent and reliable results in challenging glass grinding applications in glass thicknesses of 0.5 mm, 0.7 mm, 1.1 mm and 1.5 mm.

We also offer a full line of glass grinding coolants, including a new synthetic coolant with outstanding lubricity, to increase tooling life for thin glass processing.

Cutting Wheels

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.

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

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: When using a 3.0 mm OD cutting wheel, it must be used with the correct post for the best cutting response and fit. The height is adjusted in the post, so you won’t need to adjust the height on your cutting bridge. For example, on a Bystronic cutter, the correct post is 66260169007.

Carbide Cutting Wheels

For thin glass operations, 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.

Available in angles from 105° – 160° for glass thickness from .4 – 1.6 mm
Available in a smaller 3.0 mm OD for shape cutting of thin glass, with recommended angles from 105° – 134°

Also available and matched to the cutting wheel, SUPER-CUT posts allow our cutting wheels to fit any cutting machine on the market.

Pencil Edging Wheels

SUPER-CUT diamond pencil edging wheels are engineered to your needs. Our diamond/bond specification meets the extremely high edge requirements for thin glass. You’ll get a ground edge so smooth and chip-free that it will even pass the microscope exam.

SUPER-CUT wheels provide:

Fast startup
High edge quality
The best wear rates in the industry
Superior grind quality makes it easy to polish
Available in standard sizes:
- U2 (U60 mm)
- U4 (U100 mm)
- U6 (U150 mm)
- U7 (U175 mm)
- U8 (U200 mm)
- U10 (U250 mm)

Thin glass requires special handling and a special profile with multiple radius, blended to a complex shape. SUPER-CUT EDM profiles will give you the exact shape you design. Let us design the profile that’s perfect for your application.

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.

SUPER-CUT manufactures pencil edging wheels for all straight line machines, double edgers, CAM or CNC grinders. We 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.

Diamond Drill Bits

SUPER-CUT diamond drills allow for rapid penetration of the glass surface and improved hole quality.

While it is not recommended to drill thin glass, SUPER-CUT drills can drill the hole if necessary prior to chemically strengthening the glass. Routers and seamers are also available.

Core Drills

Our one-piece straight core drills offer fast performance and amazing life, in sizes from 4 mm to 180 mm OD. SUPER-CUT has developed specifications especially for drilling thin glass. Shank design will be selected to fit your equipment.

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.

TIP: Due to the fragile nature of the raw thin glass, we recommend drilling with the appropriate coolant. Ask your SUPER-CUT engineer for a recommendation.

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.

We offer a line of dressing sticks specially designed for thin glass applications. A relatively softer abrasive is used to provide greater diamond exposure.

The SUPER-CUT Advantage: Highly friable grains allow quick and consistent re-sharpening, lower diamond wear, and longer tool life.

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.
