When it comes to durability, you would be hard pressed to find machines that stand the test of time the way Blanchard grinders do. That’s one of the reasons F.P. Miller Co. specializes not only in Blanchard grinder repair and remanufacturing of your current Blanchard grinders, but also sales of Blanchard grinders and parts. Don’t trust your most valuable equipment to just anybody. Trust the professional technicians at F.P. Miller Co.
At F.P. Miller Co., our expertise in Blanchard grinder repair and remanufacturing comes from our fine-tuned process that covers your grinder from top to bottom. Let’s take a quick walk through the process:
To get an idea of what we are working with, we will start by disassembling a grinder down to the base castings. Once that is done, every piece is cleaned and inspected for wear.
Gearboxes are disassembled and inspected for wear. In this part of the process, all bearings and seals are replaced. Upon reassembly, the gearboxes are checked to ensure they operate smoothly and quietly. The saddle is removed and the mating wear surfaces are machined and/or scraped to ensure these surfaces will provide “as new” tolerances when grinding. If needed, way material (Moglice and Cast Iron Inserts) may be added. Finally, primer and paint is applied before reassembly.
In the next step of the process, the chuck is removed, turned over and the mating wear surfaces are scraped. As with the saddle and gearbox, way material (Turcite and Rulon) may be added to replace the material removed from these surfaces, again, to ensure correct alignment with adjoining surfaces. Primer and paint is applied before reassembly, as well.
The vertical column and spindle drive motor are removed and completely disassembled to guarantee inspection of the entire spindle. The vertical column and the spindle housing mating wear surfaces are machined and/or scraped (as needed) to ensure these surfaces will also provide “as new” tolerances when grinding. As in previous steps, way material (Cast Iron Way material) may be added to replace the material removed from these surfaces to ensure correct alignment with adjoining surfaces.
In the next step, we disassemble the spindle drive motor, clean all the components, and inspect for damage. As part of this process, we test, recoat and bake the motor windings. If we notice, however, that the windings are damaged or do not pass testing, we rewind the motor. Prior to reassembly, we replace the spindle bearings, then apply primer and paint.
At this juncture, we machine the base ways, then clean the base before applying primer. We begin the reassembly by attaching and aligning the vertical column. The horizontal and vertical way surfaces are reconditioned and primer is applied.
Nearing completion, all small components are painted and prepared for reassembly. At this stage, coolant pumps, table and spindle feed motors are tested and, if necessary, replaced.
Finally, we mount the rebuilt spindle drive. We also fabricate and mount new guards on the grinder. We also install completely new wiring.
