High Speed Carbide Scoring Wheels (CHS)

Fletcher’s “CHS” (CNC Ground, High Speed Score) carbide wheels are produced from a specially formulated micro-grain tungsten carbide material developed exclusively for Fletcher-Terry.

This fine particle carbide composition gives each cutting wheel extraordinary performance strength and resilience. Our formula ensures the cutting properties of our wheels remain consistent, which means superior edge quality and easy clean break out for your end glass product.

Fletcher’s CHS Carbide wheel is produced using a CNC proprietary method resulting in top scoring performing for high-speed glass scoring applications commonly found in float plants.

Depending on glass thickness and type, Fletcher’s CHS Wheels are available from 119° to 155° angle. Scoring wheels can be packaged individually in tubes of 20 wheels or pre-assembled with wheel, axles and insert packaged in blister type packaging.

What Makes the CHS unique and different from other glass scoring wheels

1. CNC manufacturing batch start-up requires a percentage of wheels be
approved prior to full batch production

2. In-process batch control continues through-out the CNC grinding process for
maintaining the strict QC standards

3. For final QC inspection, Fletcher utilizes an in-house designed and fabricated
high speed testing system for qualifying wheel scoring quality and consistency

High speed testing at 40 inches/second

Areas to consider for glass scoring

Cutting Force - Cutting force works in conjunction with the cutting wheel diameter and angle
Cutting Wheel Diameter & Angle - When selecting the appropriate cutting wheel, one needs to determine glass thickness and if straight or shape (pattern) is needed
Speed of Cutting Wheel - Typically operating parameters are set to yield a certain score quality, ease of break-out, and edge quality
Cleanliness of Glass

Carbide Scoring Wheels

Created from an exclusively formulated micrograin, tungsten carbide composition for extraordinary strength and resilience
Lubrication treatment is applied to each Fletcher cutting wheel & axle pro-longing life of cutting edge by reducing friction
Our precision ground, tungsten carbide axles are available in outside diameters of .049” (1.25mm) to .116” (2.95mm), and offered in 9 different lengths

When selecting the proper wheel, Fletcher recommends a four step selection process.

Step One: O.D. Selection – Determine the outside diameter of the wheel based on thickness of the glass. Smaller O.D.’s provide for finer adjustment, larger I.D.’s provide extend life.

Step Two: I.D. Selection – Determine the inside diameter

Step Three: Angle Selection – Determine type of cut either Straight or Shape cutting. Refer to charts below for additional information.

Step Four: Wheel Grind – RG (Regular Grind) most versatile grind used for straight and shape cutting; CR (Course Grind) used for tube cutting and for irregular surface cutting; PL (Polished) use for very thin and specialty glass cutting
