H45 & H55

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 H45 offers a work range of 700×500 mm, while the H55 provides 1,300×800 mm. Both machines feature vertical grinding head adjustments and support planetary mode grinding with various wheel diameters. They can perform taper grinding with a maximum included angle of 90 degrees.

Table and Feeds: The H45 has a working surface of 770×630 mm and supports loads up to 500 kg, whereas the H55 has a surface of 1,440×860 mm and supports up to 800 kg. Machining speeds reach up to 2,000 mm/min, with traversing speeds of 4,000 mm/min.

Grinding Spindle: The spindle sleeve diameter is 125 mm, with adjustable speeds for different motors ranging from 4,000 to 70,000 min-1. The grinding turbine can reach speeds up to 130,000 min-1.

Control System: Equipped with CNC controls for multiple axes, the machines use the Fanuc 300i system and integrate HAUSER SOFTWARE CYCLES for jig grinding.

Guideways and Drives: A combination of sliding and linear guideways with oil-pressurized lubrication is used to prevent stick-slip effects. Centralized axes drives minimize friction.

Options and Accessories: Features include a new HAUSER jig grinding head, an ATC automatic tool changer with 12 positions, a CBN dressing unit, and a multi-sensor system for automatic grinding wheel calibration. Additional rotary and tilting axes are available.

Technological Advancements: The machines combine jig grinding and hard milling, offering high rigidity, reduced cycle times, and enhanced grinding autonomy with U-axis capacity up to +47 mm.

Technical Specifications: Adjustable and programmable speeds for electric grinding motors range from 4,000 to 70,000 min-1, with a grinding turbine system capable of 130,000 min-1. The C-axis planetary mode offers speeds from 5 to 350 min-1, and the Z-axis features an alternating stroke mode with speeds from 0.5 to 22,000 mm/min and a stroke length up to 170 mm.

Work Range: The H45 provides adjustments of 700x500 mm, and the H55 offers 1,300x800 mm. Vertical adjustment of the grinding head is 500 mm for the H45 and 635 mm for the H55, with table surface clearance up to 785 mm for the H45 and 905 mm for the H55.

Table Specifications: The H45 table measures 770x630 mm with a load capacity of 500 kg, while the H55 measures 1,440x860 mm with a capacity of 800 kg (1,500 kg with extension). The table includes 6/7 T-slots, each 14 mm wide.

Accuracy: Positional uncertainty for axes X, Y, and W is 0.0025 mm, compliant with VDI/DGQ 3441 standards.
