Precision Blanchard & Surface Grinding Services

Venango Machine Company offers industry-leading Blanchard grinding services in PA, delivering exceptional precision and surface finish for a wide range of industrial applications. Our facility near Erie, Pennsylvania, is equipped with large-capacity Blanchard grinders featuring a 72″ magnetic chuck, 84″ swing, and 22″ grinding height, an ideal combination of equipment for removing stock quickly and achieving superior flatness and parallelism across the surface face with tight tolerances. Also referred to as rotary grinding throughout the industry, this material removal process is trusted for its ability to generate a consistent cross-hatched surface finish on materials such as mild steel, stainless alloys, mold steels, castings, and forgings.

With over 50 years of hands-on experience, Venango Machine has become a trusted source for Blanchard grinding services in Pennsylvania. Venango also offers value-added services, including supplying materials ground down to the correct size, helping customers streamline production, and reducing shipping costs. Our team is capable of holding tight tolerances and working with large and heavy workpieces, including our custom-built steam, electric, or thermal fluid platens, making us a valuable partner for demanding manufacturing and fabrication environments.

Industries/Parts Requiring Blanchard Grinding Services

• Mold and die bases for the plastics and rubber industries
• Large plate work in the steel and fabrication sectors
• Tooling components for aerospace and defense applications
• Precision-machined parts for heavy equipment manufacturers
• Base plates and mounting surfaces for machine builders

When quality, consistency, and fast turnaround matter, manufacturers across the region turn to Venango Machine for reliable Blanchard grinding services in PA.

Venango Machine Company provides high-precision surface grinding services in PA for manufacturers that require tight flatness tolerances, low Ra finishes, and consistent material removal across long components and broad surface areas. Our horizontal Supertec surface grinder features a 40″ wide table (with 80″ blend capacity), 118″ in grinding length, and 22″ in height clearance, making it ideal for large workpieces and tooling plates. This equipment enables us to achieve exceptional parallelism and precision across long, flat surfaces, an essential factor for any industry that demands dimensional accuracy and repeatable results.

Unlike rotary grinding or Blanchard grinding, surface grinding removes material with minimal stock removal, producing a smoother surface and a greater degree of control regarding the finish. Venango uses aluminum oxide grinding wheels in conjunction with a magnetic chuck to carefully guide parts under the spindle. Our ability to hold tight tolerances and control surface finish makes surface grinding especially critical in the manufacture of custom steam, electric, or thermal fluid platens used in compression molding and high-pressure systems. Flatness, parallelism, and surface uniformity are directly linked to the thermal transfer efficiency and sealing performance of these systems.

Industries/Projects That Benefit from Surface Grinding Services

• Mold plates and die tooling for rubber, plastic, and composite molding
• Heated platen systems requiring ultra-flat mating surfaces
• Base plates and machine tables for heavy manufacturing equipment
• Structural components for automation and defense systems
• Weldments and large fabricated assemblies needing post-process grinding

With decades of experience in grinding mold plates, machine bases, and custom platens, Venango Machine has built a reputation as one of the most capable surface grinding providers in Pennsylvania. We support both prototype and full production work and routinely deliver fast turnarounds for OEMs and contract manufacturers across the Northeast.
