JUMAXIMAT - High-productivity complete grinding of cutting tools

Product catalog summary

Overview: The JUMAXIMAT is a high-productivity grinding machine designed for the complete machining of high-precision cutting tools. It is suitable for tools made from HSS or HM, including end mills, reamers, and thread milling cutters, with diameters ranging from 6 to 32 mm.

Machine Features: The JUMAXIMAT offers flexible and efficient machining with the ability to grind tools from solid blanks. It supports both unsupported and tailstock-supported grinding, with optional steady rest support. The machine uses corundum or CBN grinding wheels for HSS tools and diamond wheels for tungsten carbide tools. Up to four grinding wheels can be mounted, and the wheelhead can swivel 53° left and 90° right. All adjustments are CNC-controlled.

Advantages: The machine allows for complete machining of the entire tooth geometry in one clamping, reducing retooling times and offering high flexibility. All relief angles are programmable, requiring only one grinding wheel.

Control System: The JUMAXIMAT uses the Erwin Junker Operator Panel (EJ-OP) for control, featuring a modern interface with a color monitor and integrated PC. The integrated dressing system allows for automatic profiling and dressing of grinding wheels, monitored by impact sound sensors.

Software: The JUWOP/W software package enhances precision machining by allowing tool and grinding wheel programming, task definition, grinding wheel profile calculation, and 3D simulation.

Technical Data: The machine dimensions are 3,460 x 2,665 x 2,050 mm, with a weight of approximately 8,000 kg. It supports workpiece diameters of 10-32 mm (standard) and 6-20 mm (optional), with a maximum grinding length of 200 mm. The grinding spindle has a drive rating of 20 kW (11 kW optional) and supports up to four grinding wheels.

Automation: The JUMAXIMAT features an open interface for automation, allowing the use of JUNKER or non-JUNKER systems. It supports various transport systems, including pallets and cassettes.

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