JUMINIMAT - High-productivity complete grinding of cutting tools

Product catalog summary

Overview: The JUMINIMAT is a high-precision grinding machine designed for the complete machining of high-precision cutting tools. It features an integrated loading system for flexibility and productivity, capable of handling tools made from HSS or HM with diameters ranging from 1 to 8 mm.

Applications: The machine can process various cutting tools including end mills, die-sinking cutters, roughing mills, 1-tooth milling cutters, reamers, tap drills, counterbores, wood borers, and wood form cutters.

Technology: The JUMINIMAT uses corundum or CBN grinding wheels for HSS tools and diamond grinding wheels for tungsten carbide tools. It offers complete machining of the entire tooth geometry in one clamping, high precision, and flexibility with reduced retooling times. All relief angles are programmable, requiring only one wheel.

Control System: The machine is operated via the Erwin Junker Operator Panel (EJ-OP), a modern controller with a color monitor and integrated PC. It includes an integrated dressing system for automatic profiling/dressing of grinding wheels.

Software: The JUWOP/W software package facilitates the programming of tools and grinding wheels, definition of machining processes, calculation of grinding wheel profiles, and 3D simulation.

Technical Specifications: The machine dimensions are 3,273 x 3,008 x 2,100 mm with a weight of approximately 2,800 kg. It supports workpiece diameters of 1-8 mm and lengths up to 105 mm. The grinding spindle can swivel up to 53° left and 105° right, with CNC-controlled movements for precision.

Contact Information: The document provides contact details for JUNKER offices in Europe, Asia, and North America, including phone numbers, fax numbers, and email addresses.
