With 3 plant locations totaling at approximately 100,000 combined square feet of brick and mortar, QQE can handle all of your machined quartz requirements. We offer a complete array of services and capabilities to enhance your quartz experience with us.
Partnering with all of the major raw material suppliers such as Momentive Performance Materials, Hereaus Quartz Glass, Tosoh SGM, Qsil, and others, QQE can supply the material of your choice. If your choice of material is not in our inventory, we can get it!
By virtue of our highly integrated, highly efficient and intelligently networked manufacturing systems, QQE can meet the most demanding of requirements. All processes are strictly controlled and performed in-house by our highly experienced team members, ensuring exceptional quality, repeatability and consistency.
CAD/CAM engineering support
QQE verifies each customer drawing and specification prior to programming and manufacturing the part. We are able to simulate the part and machining, ensuring the highest quality available.
With more than 50 years of combined experience, QQE can fire polish surfaces that can’t be mechanically polished or when the requirement is that the surface needs to be sealed. Processing is done in controlled environments to maintain the highest level of quality and purity.
CNC Machining (Lathe and Mill)
Our craftsmen are able to program and machine your most challenging requirements. Proprietary custom macros, fixtures and tooling are utilized to provide our customers the most efficient and highest quality parts available. Our design review teams are available to help with your designs, offering process improvement and cost reduction opportunities.
- Diameters up to 36"
- Typical tolerances +/-.002"
- 4th and 5th axis turning centers
Grinding & Polishing
Double and single side polishers are used to achieve highly accurate ground and polished plates. Our technicians have decades of experience polishing quartz materials, assuring our customers superior quality.
- Diameters up to 36"
- Flatness to .0005" (upon request)
- Surface parallelism to .0005" (over 23" diagonal)
A highly accurate tool for cutting complex shapes and parts that may have large quantities of features (e.g., holes, slots). A CO2 laser can be used for cutting flat materials and tubing.
- Thickness from .020 to .375"
- Diameters up to 24"
- Lengths up to 24"
- Holes greater than .010"
Water Jet Cutting
A useful tool incorporating water at high velocity and pressure, along with an abrasive media, capable of cutting a variety of materials including quartz and ceramics. In many applications, a water jet may be used instead of other cutting tools (e.g. laser, diamond saw) offering efficiencies that the others may not.
- Diameters up to 48"
- Thickness up 4" (typical)
- Edge finishes ~200uin ra
This critical operation allows for accurate removal of material and can be either the precursor to other operations or can be offered as the final machining step.
- Diameters up to 42"
- Surface finishes from 8uin to 63uin
- Thicknesses from .020" to 20"
QQE has an extensive library of core drills, allowing for the most efficient material removal. This ultimately saves you money and allows QQE to be leaders in material efficiency. The use of multiple radial arm drills allows QQE superior throughput in this critical pre-process phase.
- Diameters up to 25"
- Diameters greater than 4" are in ¼" increments
- Diameters less than 4" are available in the most commonly used diameters
Sawing & Slicing
QQE utilizes a variety of saws for processing all sizes and shapes quartz, ceramic and other similarly hard materials. Applying more than 50 years of experience, our assortment of diamond and silicon carbide saws can handle a wide variety of applications.
- Diameter up to 42"
- Annular sawing capability up to 13.5" with minimal kerf loss
- Lengths up to 44"
ISO 5 (ISO 14644-1) Cleanroom Packaging
Clean room packaging in an ISO 5 (ISO 14544-1) certified clean room is available upon request. Contact our capable staff and we will assist you with your specific packaging requirements.
QQE offers various types of cleaning for your specific need. This can range from basic aqueous detergent cleaning to various types of precision cleaning, measured in atoms per square centimeter.
Our company has built its name on quality. Our experienced inspectors and operators are skilled in the use of metrology tools, drawing interpretation, GD&T and visual characteristics, ensuring the highest quality throughout the manufacturing process.
