Index B42 Precision Cylindrical Grinder - German Engineering - Hahn & Tessky
Overview
The Index B42 represents classic German precision grinding technology from Hahn & Tessky in Esslingen-Neckar. This robust cylindrical grinder is engineered for high-precision grinding operations, featuring a rigid cast-iron bed, precision spindle bearings, and a comprehensive range of spindle speeds. The machine embodies the quality and durability that defined mid-century German machine tool manufacturing, with a design philosophy focused on accuracy, repeatability, and longevity.
This particular example showcases the mechanical sophistication of the era, with a full complement of change gears visible in the open gear cover, allowing operators to select from multiple spindle speed combinations. The machine features a Siemens electric motor rated at 6.5 kilowatts, delivering consistent power for grinding operations across a wide speed range. The work spindle is mounted on precision rolling element bearings, and the tailstock provides adjustable support for through-grinding applications. The coolant system is integral to the design, with visible pump and distribution components.
In today's market, precision cylindrical grinders of this calibre command strong interest from tool and die shops, precision engineering facilities, and collectors of quality machine tools. Comparable Index and similar German grinders (Schaublin, Studer, Okuma) in working condition typically realise AUD $3,500 to $8,500 depending on condition, completeness, and operational status. This example, with its original configuration and visible mechanical integrity, represents solid value for buyers seeking a proven workhorse for precision grinding applications.
Condition
The machine displays honest working condition consistent with industrial use over several decades. The exterior green paint shows surface patina and minor wear, with some areas of light surface corrosion typical of age and workshop environment exposure. The cast-iron bed and column structure show no visible cracks or structural damage. The work spindle rotates freely with no apparent binding or play. The tailstock assembly is intact and moves smoothly along the bed ways. The precision grinding wheel is mounted and appears to have usable life remaining. All visible mechanical components, including the change gear train, spindle bearings, and feed mechanisms, are present and mechanically sound. The coolant system components are intact, including the pump and distribution lines. The machine retains its original Siemens motor and electrical configuration. Protective wrapping is present on the base, indicating recent handling care.
