3-Axis and 5-Axis Garolite Machining

At Sochain Precision, we provide both 3-axis and 5-axis CNC machining of Garolite. It’s a fiberglass reinforced laminate. We primarily produce electrical insulation parts, structural panels, mounting plates, and other precision-machined components that demand high accuracy and stable dimensions.

Initially, our engineers carefully review customers' CAD files before commencing production to ensure that the intended cutting direction, part geometry, and laminate thickness are properly designed for fabrication.

Garolite has high rigidity and an abrasive nature. Therefore, it requires meticulous tooling selection and optimized machining parameters to preserve edge quality and dimensionally consistent results.

Garolite machined parts

In general, we employ 3-axis machining for flat surfaces, drilled holes, slotted cuts, pocketed areas, and certain profile cuts.

However, 5-axis CNC machining is used for features with an angle to them (or even multiple angles), and complex contour cuts that would typically require additional setups. This process allows for achieving high accuracy and improved machining efficiency when completing multiple sides at one time.

The tolerance achievable through machining may vary depending upon the particular laminate grade being processed, but tolerances of +/-0.1 mm are possible. Additionally, by keeping optimized machining parameters, we prevent machining edge fraying, surface chipping, and excessive tool wear that occur during processing.

What is Garolite Machining?

Garolite machining refers to machining fiberglass reinforced laminates into assembly-ready final products. It involves a CNC tool traveling along digitally defined pathways (toolpaths), which allow for the removal of material from the workpiece while maintaining stable dimensions and clean feature definition.

Garolite features excellent electrical insulation properties, as well as superior mechanical properties, thermal stability, and resistance to absorbing moisture. A large number of insulating spacers, mounting plates, electrical barriers, washers, fixtures, and structural composite parts are manufactured via this CNC machining process.

Basic Process Steps

Design Preparation: Before machining, CAD models or drawings are examined to confirm that all required design specifications (dimensions, tolerances, etc.) are precisely included in the model. Each Garolite type has unique physical properties, and therefore, the specific material being machined must be identified before commencing the machining process.

Toolpath Programming: Once the design preparation phase has confirmed acceptable design specifications, computer-aided manufacturing (CAM) software is used to generate programmable digital paths (cutting paths) that will guide the CNC milling operation.

Since there are several types of garolite available (each having unique physical characteristics), the specific type being machined dictates the exact parameters that are entered into the CAM software.

Material Setup: Once the toolpath programming is completed, the garolite sheet/panel is then positioned onto a fixture system specifically designed to minimize vibrations during machining and maximize stability.

Rough Machining: Large-diameter cutting tools are used for initial stock removal, yielding a rough approximation of the final product's size and shape.

Detail Machining: By using smaller diameter cutting tools, finer details such as slotted cuts, pocketed areas, drilled features, etc., are machined.

Edge Finishing: Additional finishing passes are made to further refine the edge quality and help eliminate any burrs and frayed material edges created during the aforementioned steps.

Inspection and Delivery: All finished parts are inspected for accurate dimensions before packaging and shipping to customers.

More of Our Garolite Machining Capabilities

Different machining techniques are used to produce unique garolite parts, dependent upon the type (thickness), shape, edge finish, and/or assembly constraints. Based on the part design, our team determines which cutting technique(s) would best suit the part's production run quantity.

Garolite Panel Cutting

Garolite panels can be machined in many ways. One common way to machine a flat sheet of Garolite material is by panel cutting. This method produces small production blanks from larger flat sheets, as well as finished shapes/profiles with high dimensional accuracy.

CNC Drilling for Garolite

CNC hole making is used to create mounting holes, fastener holes, alignment features, and electrical connections for Garolite assemblies. Through optimized drilling, we minimize break-out at the edges and prevent edge damage from the glass fiber reinforcement within the fiberglass material.

Garolite Slotting and Pocketing

Slotting and pocket machining are employed as additional machining techniques. These help create parts requiring recessed sections, cable pathways, clearances for other parts, and lightweight structural elements. Our team selects tools and controls cutting depths to ensure stable walls and quality edges.

Edge Finishing and Deburring

After machining Garolite parts, it’s important to eliminate burrs, sharp fibers, or irregularities along the edges. Secondary operations, such as deburring and cleaning the surfaces of parts, ensure safe handling before assembly and improve part appearance.

How to Work With Us: A Simple Procedure

Getting custom Garolite parts machined is straightforward. Our engineering team reviews the design, confirms machining feasibility, and manages production from material preparation to final inspection.

Upload Your CAD File

Send your 2D drawings or 3D CAD files for engineering review. We check material thickness, feature geometry, hole spacing, and machining accessibility before production begins.

Receive a Manufacturing Quote

Once you request a quote and send us your design file, our staff will provide an estimate for the part cost alongside the lead time to make it. In addition, we provide a detailed breakdown of the steps and approximate time analysis to produce your part with regard to its shape and the material type.

Confirm Production

After the customer has confirmed their order and accepted the estimated price, we begin preparing parts for production. We finalize tool paths (followed by a machine to make cuts), fixtures, and cutting techniques before starting the actual machining process.

Machining & Inspection

After machining, the parts are deburred and inspected through a CMM machine to ensure a neat edge condition and feature location before shipping.

Shipping & Delivery

All finished parts are packaged in a manner designed to protect both the machined surface and edges from damage during transit.
