Hillary Machinery supplies precision grinding machines for semiconductor, silicon carbide, quartz and ceramic applications. Chevalier advanced-material grinding systems provide high-precision processing for hard and brittle materials, including wafer grinding, backgrinding, thinning and precision surface grinding applications requiring exceptional flatness, finish and process control.
Machining and grinding silicon carbide, quartz, ceramics and semiconductor materials requires equipment capable of maintaining precision while processing hard, brittle and technically demanding materials.
Hillary Machinery offers Chevalier precision grinding systems for advanced-material applications requiring controlled material removal, dimensional accuracy, flatness and surface finish.
Silicon carbide grinding presents unique manufacturing challenges because of the material's extreme hardness and brittle characteristics. Machine rigidity, spindle performance, grinding-wheel selection, vibration control, coolant management and process parameters can all influence grinding performance and finished-part quality.
Precision grinding systems can be used to remove material while controlling flatness, thickness and surface condition in suitable silicon carbide applications.
Quartz grinding requires controlled material removal to reduce the potential for chipping, cracking and other damage associated with brittle materials.
Precision grinding equipment can be applied to quartz components used in semiconductor manufacturing and other industries where dimensional accuracy and surface quality are critical.
Advanced ceramics can provide exceptional hardness, wear resistance, thermal performance and other desirable properties, but these characteristics can also make conventional machining difficult.
Precision ceramic grinding provides a method of producing accurate surfaces and dimensions on suitable ceramic components using the appropriate grinding machine, wheel and process.
Semiconductor manufacturing can require extremely precise grinding and material removal processes to control wafer thickness, flatness and surface condition.
Grinding systems used in semiconductor applications must provide the machine rigidity, controlled motion, spindle performance and process stability required for demanding wafer and advanced-material processing.
Wafer backgrinding is used to reduce wafer thickness after front-side processing. The grinding process removes material from the backside of the wafer to achieve the required final thickness.
As wafers become thinner, process control becomes increasingly important because dimensional variation, vibration and mechanical stress can affect the finished wafer.
Machine configuration and process requirements should therefore be evaluated around the specific wafer material, starting thickness, final thickness, flatness and surface-finish requirements.
Hillary Machinery offers Chevalier grinding machines for silicon carbide, quartz, ceramic and semiconductor-related applications.
Current systems include Chevalier FRG-series rotary surface grinders configured for precision advanced-material grinding.
Explore Chevalier Grinding Machines
Chevalier FRG rotary surface grinders incorporate design features intended to support precision grinding and demanding surface-finish requirements.
The FRG design uses a hydrostatic worktable, where the table is supported by a controlled oil film to provide smooth rotation, vibration resistance and rotational precision.
These characteristics can be particularly important when grinding brittle advanced materials where vibration and process instability can affect surface quality and dimensional accuracy.
Grinding-wheel condition and balance can have a significant effect on surface finish and process stability.
Chevalier FRG machines incorporate in-machine dynamic balancing technology designed to control grinding-wheel vibration during precision grinding applications.
Precision advanced-material grinding requires coordination between table motion, grinding-wheel speed and infeed.
Chevalier FRG systems incorporate adaptive finishing capability that can adjust grinding parameters to support the required finishing process.
Rotary surface grinding uses a rotating worktable beneath the grinding wheel. Continuous table rotation can provide efficient and consistent presentation of the workpiece to the grinding wheel.

Precision grinding systems can support a range of advanced manufacturing applications involving:
Silicon carbide, quartz and advanced ceramics behave differently from conventional metallic workpieces. Successful grinding requires controlling the complete process rather than simply applying conventional surface-grinding parameters.
Important considerations can include:
Machine selection should begin with the material and finished-part requirement. Hillary Machinery can help evaluate:
Silicon carbide can require a rigid precision grinding machine with appropriate grinding-wheel technology, spindle performance, vibration control and process parameters selected for the specific material and application.
Yes. Quartz can be precision ground using suitable grinding equipment and processes designed to control material removal, dimensional accuracy, chipping and surface finish.
Many technical ceramics can be precision ground when the grinding machine, wheel, coolant and process are appropriate for the specific ceramic material.
Wafer backgrinding removes material from the backside of a semiconductor wafer to reduce it to the required final thickness while controlling dimensional accuracy and surface condition.
Excessive vibration can negatively affect surface finish, dimensional accuracy and process stability and can be especially problematic when processing hard, brittle materials.
Important factors include the material, workpiece dimensions, material-removal requirements, required flatness, thickness control, surface finish, spindle performance, workholding, grinding-wheel technology and production volume.
Hillary Machinery can help evaluate your material, workpiece dimensions, required thickness, flatness, surface finish and production requirements to determine the appropriate Chevalier grinding solution.
