For Fribosa service<\/strong> covering overhaul, repair, and spare parts, SPREITZER is now the central point of contact.<\/p>\n\n\n\n Overhaul: <\/strong>metrological inspection of parallelism and squareness, restoration of factory accuracy \u2014 with a free cost estimate in advance. The pull-down vises made by Fribosa AG are still in use today in toolmaking companies, in grinding shops, and on jig boring machines. The manufacturer no longer exists \u2014 the workholding devices keep working. As a result, there is no longer a point of contact for overhaul, repair, and spare parts. We are taking on that role.<\/p>\n\n\n\n Parallelism and squareness change.<\/strong> The clamping surfaces wear, and the workpieces become inaccurate. The fault is often looked for in the machine first, not in the workholding device. If repair is no longer cost-effective, the EHS precision pull-down vise from our production replaces the existing workholding device. The pull-down system pulls the movable jaw downward during clamping and prevents the workpiece from lifting: no tapping down, no chatter. Both versions are through-hardened, precision-ground on all sides, and can be used on all four support surfaces \u2014 with 0.002 mm parallelism and 0.003 mm squareness.<\/p>\n\n\n\n Typical applications:<\/strong> grinding machines, jig boring machines, precision machines, and measuring and inspection rooms.<\/p>\n\n\n\n
Repair:<\/strong> reconditioning of clamping jaws, spindles, and housings \u2014 even without original documentation.
Spare parts<\/strong>: replacement parts from our product range or made to measure.
Alternative:<\/strong> the EHS pull-down vise from our own production, if repair is no longer cost-effective.<\/p>\n\n\n\nWhat happens over the years<\/h2>\n\n\n\n
Individual parts fail.<\/strong> Clamping jaws, spindles, guideways. Without the manufacturer, you need someone who can reproduce the part.
Requirements change.<\/strong> A new machine, a different range of workpieces, automation \u2014 the existing workholding device no longer fits the concept.<\/p>\n\n\n\nWhat we offer for Fribosa workholding devices<\/h2>\n\n\n\n
Overhaul<\/strong><\/h3>\n\n\n\n
We inspect parallelism and squareness with measuring equipment and restore factory accuracy. You receive a free cost estimate in advance \u2014 including an assessment of whether an overhaul is more cost-effective than a replacement.<\/p>\n\n\n\n
Repair<\/strong><\/h3>\n\n\n\n
We repair defective clamping jaws, spindles, or housings, even without drawings. Photos, the type designation on the unit, or a short phone call are enough as a starting point.<\/p>\n\n\n\n
Spare parts<\/strong><\/h3>\n\n\n\n
We supply clamping jaws, spindles, T-slot nuts, and other replacement parts from our product range or manufacture them to measure. A drawing, a dimensioned photo, or the original part for measurement is sufficient.<\/p>\n\n\n\nThe alternative: EHS pull-down vise<\/h2>\n\n\n\n
