Linear Motion Accessories

For our metrology gages, rotary and linear axes and complete motion systems, ABTech manufactures accessories at our Swanzey, New Hampshire, facility, including:

• Gage stands
• Inspection-grade granite surface plates and frames
• Dual element filter/regulators
• Linear translation stage
• Fixtures and tooling

GAGE STANDS

ABTech’s quality tool room and inspection-grade gage stands provide stable support and long reach for your mechanical indicators or electronic probes, to enable fine adjustment and access to deep bores. Fixed or adjustable base options, additional swivel and arm assemblies, arm extensions and a range of sizes are available for both shop floor and ultra-precision quality control applications.

Our tool room gage stands (GST) come with a fine-adjust three-point contact tilt base and a large footprint for stability. The gage arm swivels vertically and horizontally and fully extends with a secure position locking feature.

• GST-18P/10A: 18” (450mm) post height, 10” (250mm) arm length
• GST-24P/12A: 24” (600mm) post height, 12” (300mm) arm length

Inspection style gage stands also feature a portable but stable three-point contact base. The rectangular vertical posts have rack and pinion drives, while the horizontal arms have friction drives for precise positioning of measurement probes.

• GSI-24P/12A: 24” (600mm) post height, 12” (300mm) arm length
• GSI-36P/18A: 36” (900mm) post height, 18” (250mm) arm length
• GSI-48P/24A: 48” (1200mm) post height, 24” (600mm) arm length

GRANITE SURFACE PLATES AND FRAMES

We designed our natural solid granite bases with welded and epoxy painted steel frames and adjustable vibration-isolation leveling feet. Available in inspection, tool room or lab grade, and in many sizes and configurations  (including multi-level and gantry bridges), these surface plates provide a stable foundation for ABTech's ultra-precision motion systems. Options include threaded inserts for mounting additional components; an on-board air supply tank (for safe emergency shutdowns); or passive air isolation base systems to enhance the granite’s natural ability to isolate vibrations.

DUAL ELEMENT FILTER/REGULATORS
(Highly Recommended for All Air Bearing Systems)

ABTech offers two filter/regulator assemblies; both keep air line contaminates (such as water, oil or solid particles) from entering into the small restrictors in your air bearings. They both come with 5.0 micron pre-filters, a wall mount bracket and 6 feet (2m) of air hose and fittings.

• 00787AC: 0.5 micron coalescing secondary filter
• 00938AD: 0.3 micron coalescing secondary filter

LINEAR TRANSLATION STAGE

ABTech’s mechanical air bearing linear translation stage adapts to single axis or stacked stage configurations, with high resolution and repeatability over long travel. Designed for the highly demanding optics industry, it achieves vertical and horizontal straightness of 40 micro-inches/inch (1 micron/25mm).

The linear translation stage consists of super precision cross-rollers with fine adjust micrometer, allowing optical technicians and quality control inspectors to locate the crown of lenses for surface profilometry.

• LTS100: Linear translation stage with 4 inch by 4 inch (100mm by 100mm) carriage top

PRECISION FIXTURES AND TOOLING

Standard or custom options for aligning and holding your tool or parts include scroll type or workholding chucks and precision collets. Challenge our engineers to design a fixture for your unique application.
