Overview
The Hardinge Kellenberger H2000 is a precision CNC jig grinder and coordinate grinding machine designed for high-accuracy hole grinding, profile grinding, and contour grinding of complex workpieces. Unlike the K-series cylindrical grinders that rotate the workpiece between centers, the H2000 uses planetary grinding with a stationary workpiece on a precision table, making it ideal for grinding precise hole patterns, bores, and profiles in mold plates, die blocks, and fixture components.
The H2000 features an X/Y adjustment range of 550 x 300 mm with a vertical W-axis travel of 450 mm. The usable table area measures 650 x 400 mm with a 300 kg load capacity and T-slot mounting. Planetary grinding with a 40 mm disc achieves bores up to 144 mm diameter in automatic mode and up to 360 mm with cantilever plates. The C-axis planetary speed is programmable from 1 to 350 RPM, enabling optimization for different bore diameters and materials.
The H2000 offers multiple high-speed motor options: the 40HS motor covers 3,600 to 45,000 RPM, the 70HS motor spans 8,000 to 70,000 RPM, and an optional air-driven turbine T15 reaches 150,000 RPM for ultra-fine finishing of small bores. The Z-axis oscillation system operates at frequencies up to 10 Hz with adjustable stroke lengths from 0.1 to 170 mm, providing the reciprocating motion needed for bore grinding and honing operations.
The H2000 runs on a Fanuc 30i-B control — the premium Fanuc platform — with a 15-inch touchscreen and Kellenberger's WHITE Solution coordinate grinding software. The 6-axis machine (8-axis optional with A/A-B rotary tables) weighs 12,500 kg and requires a 2.4 x 5.4 m footprint. New H2000 machines price between $600,000 and $950,000. The machine competes with the Moore G18, Hauser S55, and Mitsui Seiki JBG coordinate grinders in the precision jig grinding segment. Specs sourced from Kellenberger published data.

Strengths & Limitations
Strengths
- Planetary grinding architecture enables precision bore grinding in stationary workpieces — ideal for mold plates and die blocks that cannot be rotated
- 150,000 RPM air turbine option enables ultra-fine finishing of small bores where conventional spindles cannot achieve adequate surface speed
- Fanuc 30i-B premium CNC control provides the multi-axis interpolation and processing power required for complex coordinate grinding
- Programmable C-axis planetary speed from 1-350 RPM allows optimization for any bore diameter and material combination
- 6-axis standard (8-axis optional) handles compound-angle bores, tapered bores, and complex hole patterns
- WHITE Solution coordinate grinding software provides specialized programming for jig grinding operations
Limitations
- 12,500 kg weight and 2.4 x 5.4 m footprint require substantial floor space and reinforced foundations
- Price range of $600,000-$950,000 limits the H2000 to shops with consistent high-precision coordinate grinding requirements
- Coordinate grinding requires highly skilled operators who understand planetary grinding strategies and bore geometry control
- Table travel of 550 x 300 mm limits the size of workpieces compared to the larger H4000 platform

Frequently Asked Questions
01
New Kellenberger H2000 machines price between $600,000 and $950,000 depending on spindle options, axis configuration, rotary table, gauging systems, and automation. Base 6-axis machines with 40HS spindle start near $600,000. Full 8-axis configurations with 70HS spindle, T15 turbine, rotary table, in-process gauging, and automation approach $950,000.
02
In planetary grinding, the grinding spindle orbits inside (or around) the bore being ground while simultaneously rotating. The workpiece remains stationary on the table. This is the opposite of cylindrical grinding where the workpiece rotates. Planetary grinding enables precision bore grinding in large, heavy workpieces like mold plates and die blocks that cannot be mounted between centers or chucked on a cylindrical grinder.
03
The H4000 is the larger platform with 1,300 x 800 mm X/Y range vs 550 x 300 mm, 1,440 x 860 mm table vs 650 x 400 mm, 800 kg table load vs 300 kg (1,500 kg optional on H4000), and 635 mm W-axis vs 450 mm. Choose the H2000 for medium-size mold plates and die components; choose the H4000 for large mold bases, die sets, and heavy workpieces.
04
Different bore diameters require different grinding wheel sizes, which require different spindle speeds to achieve optimal surface speed. The 40HS (to 45,000 RPM) handles medium bores. The 70HS (to 70,000 RPM) handles smaller bores with smaller wheels. The T15 turbine (to 150,000 RPM) handles the smallest bores where even the 70HS cannot achieve adequate surface speed. Most shops configure two spindle options for their typical bore range.
