Grob

What Grob does

Grob Inc. is a privately held, family-owned manufacturer founded in 1929 (originally as Grob Brothers) and headquartered in Grafton, Wisconsin. The company operates from a 100,000-square-foot manufacturing facility employing more than 60 technicians and engineers, and produces two principal product lines: industrial vertical band saws (models 4V-24, 4V-36, and 6V-36) along with blade welders, guides, and accessories, and a catalog of cold-formed metal components built around the proprietary Grob Rolling process developed by founder Ben Grob in 1951.

The Grob Rolling cold forming method displaces raw material rather than cutting it, combining elements of open die forging, closed die forging, and thread rolling to produce spline shafts, spur gears, timing belt pulleys, broached sleeves, flanged bushings, and heat exchanger tubes with reported strength gains of up to 20% versus machined or hot rolled parts and near-zero material waste. The company maintains a catalog of over 2,100 existing profiles and offers custom tooling, with up to 70% of business coming from custom-designed parts. CNC machining (5-axis milling, turning, centerless grinding, surface grinding, optical inspection via CMM) is provided as a finishing service.

Grob serves enterprise customers across five primary verticals: Aerospace, Agriculture, Energy, Industrial & Manufacturing, and Transportation. The band saw line is distributed through a nationwide dealer network with an interactive locator, while cold-formed products are sold primarily through direct sales with quote-based pricing and RFQ forms. Cold-formed products and machining services support mission-critical applications such as aircraft landing gear, agricultural PTO shafts, transportation steering columns, refinery heat exchangers, and industrial machinery. The company is ISO 9001 certified, maintains a presence on the Thomasnet industrial marketplace, and has remained under family ownership with no disclosed external investors, acquisitions, or leadership changes across nearly a century of operation.

Core offering

Grob Inc. manufactures and sells industrial vertical band saws (4V-24, 4V-36, 6V-36 models) and related blade welders, guides, holders, and accessories. The company also designs and produces cold-formed metal components including spline shafts, spur gears, timing belt pulleys, broached sleeves, flanged bushings, and heat exchanger tubes using its proprietary Grob Rolling cold forming process. Complementary CNC machining, broaching, and grinding finishing services are offered.

Product overview

Grob Inc. is a manufacturer of industrial band saws and cold-formed metal products. The company offers two main product lines: (1) Band Saws including the 4V-24, 4V-36, and 6V-36 models, along with blade welders, guides, holders, and various accessories; and (2) Cold-Formed Products including spline shafts, spur gears, timing belt pulleys, broached sleeves, flanged bushings, heat exchanger tubes, and custom broaching services. The company also provides CNC machining services including milling, turning, grinding, and surface finishing to complement their cold-formed product line. All products are manufactured at their facility in Grafton, Wisconsin, with a focus on the Grob Rolling cold-forming process that displaces material rather than cutting it.
