Hillary Machinery supplies precision surface grinders for producing flat, accurate surfaces and tight dimensional tolerances. Our Chevalier surface grinding machines include automatic, CNC, column-type and double-column configurations for applications ranging from general toolroom grinding to large-part and high-production precision grinding.
Surface grinders use an abrasive grinding wheel to produce precise flat surfaces, remove controlled amounts of material and achieve demanding dimensional and surface-finish requirements.
Hillary Machinery offers Chevalier surface grinders for toolrooms, machine shops and production manufacturers requiring precision, repeatability and productive grinding of flat surfaces.
A surface grinder positions the workpiece beneath a rotating abrasive wheel. On conventional reciprocating surface grinders, the worktable moves the workpiece back and forth beneath the wheel while controlled crossfeed and downfeed progressively remove material.
Depending on the workpiece material and application, parts may be secured using a magnetic chuck, mechanical fixture or other appropriate workholding.
Automatic surface grinders automate table movement, crossfeed, downfeed and portions of the grinding cycle to improve productivity and repeatability compared with completely manual operation.
Automatic grinding can be especially valuable for repetitive production, larger workpieces and applications requiring consistent stock removal across multiple parts.
CNC surface grinders add programmable control over machine movement and grinding cycles, allowing operators to establish repeatable processes for demanding production applications.
CNC control can be particularly useful when part geometry, production volume or process complexity requires greater automation and repeatability.
Hillary Machinery offers Chevalier surface grinding machines across multiple configurations for precision and production grinding.
Available Chevalier designs include fully automatic precision surface grinders, column-type machines and fixed-beam double-column surface grinders for larger workpieces.

Column-type surface grinders provide a rigid machine structure for applications requiring precision grinding across larger workpieces or demanding production cycles.
Machine selection should consider grinding area, workpiece weight, required stock removal, spindle performance and the required dimensional accuracy and surface finish.
Double-column surface grinders are designed for substantially larger workpieces that require a wide grinding envelope and rigid machine construction.
These machines can be well suited for large dies, molds, machine components, tooling and other workpieces where conventional smaller surface grinders do not provide sufficient capacity.
Conventional surface grinders typically use a reciprocating table that moves the workpiece back and forth beneath the grinding wheel.
A rotary surface grinder instead rotates the workpiece beneath the grinding wheel. Rotary machines can be especially effective for circular parts, multiple-part setups and certain production grinding applications.

Surface grinders are primarily designed to produce flat surfaces. Cylindrical grinders are designed primarily for grinding outside diameters, inside diameters and other cylindrical features.
Manufacturers requiring precision grinding of shafts, bores and cylindrical components should consider an ID/OD cylindrical grinder.

Precision surface grinders are used across toolrooms and production manufacturing for applications including:
Surface grinding can be applied to a wide range of materials when the grinding wheel, machine, coolant and process parameters are selected appropriately.
Common applications involve steels, tool steels, cast iron and other metallic materials. Specialized grinding processes can also be developed for other materials when appropriate equipment and abrasive technology are used.
Magnetic chucks are commonly used to hold ferrous workpieces during surface grinding. They can provide distributed holding force while leaving the upper surface accessible to the grinding wheel.
Workpiece size, shape, material and grinding forces should always be considered when determining the appropriate workholding method.
Surface grinding is commonly selected when a manufacturing process requires tighter flatness, parallelism or surface-finish control than can be achieved economically through conventional milling alone.
Final grinding results depend on the machine, grinding wheel, wheel dressing, workholding, coolant, material, stock allowance and grinding parameters.
Selecting the correct grinding wheel is an important part of the surface grinding process. Wheel abrasive, grit size, grade, bond and structure should be matched to the workpiece material and desired grinding result.
The best wheel for aggressive stock removal may differ from the wheel selected for fine finishing, hardened materials or other specialized applications.
Selecting a surface grinder should begin with the workpiece and required finished result. Hillary Machinery can help evaluate:
A surface grinder is a precision grinding machine that uses an abrasive wheel to remove controlled amounts of material and produce accurate flat surfaces on a workpiece.
Surface grinders are commonly used for producing flat surfaces, controlling thickness, improving parallelism, removing small amounts of material and achieving precision surface finishes.
Automatic surface grinders automate portions of the grinding cycle using machine controls, while CNC grinders provide programmable control that can support more complex and repeatable grinding processes.
Surface grinders can perform both stock-removal and finishing operations, but the practical material-removal rate depends on machine power, grinding wheel, workpiece material, coolant and the required finished condition.
Milling generally removes material using defined cutting edges and is commonly used to establish part geometry. Surface grinding uses an abrasive wheel and is often used after machining when tighter flatness, parallelism, dimensional accuracy or surface finish is required.
The required machine depends on workpiece length, width, height and weight, along with grinding-wheel capacity, stock removal, required accuracy, surface finish and production volume.
Hillary Machinery can help evaluate your workpiece dimensions, material, grinding requirements, required accuracy, surface finish and production volume to identify the appropriate Chevalier surface grinder.
