H55-400

Product catalog summary

Overview: This document outlines the technical specifications and features of the Hauser H45-400 and H55-400 jig grinding machines, focusing on their precision, capabilities, and technological advancements.

Specifications: The machines offer adjustable X, Y, and W axes, with vertical adjustments for the grinding head. They support planetary grinding modes with various grinding wheel diameters and a maximum taper grinding angle of 90 degrees. The working surface dimensions and permissible table load differ between the two models.

Feeds and Speeds: Machining speeds reach up to 2000 mm/min, with traversing speeds up to 4000 mm/min. Grinding spindle speeds are adjustable, ranging from 4000 to 70000 min-1, supported by different motors.

Accuracy and Control: Designed for high accuracy, the machines feature robust, distortion-resistant modules and thermal stability. They include CNC-controlled axes and user-friendly programming via the Fanuc 300i system, with specialized HAUSER software cycles for jig grinding.

Guideways and Drives: The machines utilize sliding and linear guideways with oil-pressurized systems to prevent stick-slip effects. Centrally located axes drives minimize friction.

Options and Accessories: Available options include a new HAUSER jig grinding head, an ATC automatic tool changer, a CBN dressing unit, and a multi-sensor system (MSS). Additional rotary and tilting axes are available for customization.

Technological Advancements: Modern grinding head technology allows for a combination of jig grinding and hard milling. The machines offer high rigidity, increased stroke speed, and reduced cycle times, with hydrostatic guided spindle bearing systems ensuring circular accuracies within 0.5µm.

Contact Information: Contact details for sales and service are provided for regions including China, USA, Canada, Great Britain, and Ireland, ensuring global support.
