What Is a Horizontal Profile Projector?

A horizontal profile projector (also known as a horizontal optical comparator) projects a magnified silhouette of the part onto a screen so operators can measure lengths, angles, radii, grooves, chamfers, and complex contours. The horizontal beam path is especially suitable for long shaft-like components, cutting tools, and workpieces that can be fixed in centers, V-blocks, or rotary fixtures.

Size / Dimensions

Horizontal profile projectors are offered from compact benchtop footprints for small parts to floor-standing frames that handle long shafts. Consider the stage travel and screen diameter together: larger stages suit valve stems, lead screws, and automotive shafts, while a 300 mm screen is often sufficient for small tooling and pins. Clearance between lens and stage should accommodate fixtures and part protrusions.

Material & Build Quality

• Frame: High-grade cast iron or stress-relieved steel weldments minimize distortion and resist shop-floor vibrations.
• Stage: Hardened, ground slides with preloaded linear bearings ensure smooth motion and low backlash.
• Optics: Multi-coated lenses and mirrors for high contrast and minimal aberrations.
• Electrical: Industrial-grade switchgear and LED drivers for long service life.

Design / Type Variations

• Benchtop Horizontal Projectors: Compact, economical, ideal for toolrooms and small-batch inspection.
• Floor-Standing Heavy-Duty: Reinforced columns and extended stage travel for long shafts and automotive parts.
• Motorized / CNC-Assisted: Programmable stage movement, auto edge-detection, and repeatable routines.
• DRO-Only vs. PC-Integrated: Choose simple DRO for quick checks or PC-integrated systems for SPC and reporting.
• Ruggedized Shop-Floor Models: Sealed ways, dust covers, and LED illumination for production lines.

Capacity / Performance

Performance is measured by optical clarity, geometric accuracy, stage repeatability, and throughput. For most machine shops, a 10× lens with surface illumination supports quick burr checks and edge verification, while 50×–100× reveals micro-features like small radii and chamfers. Motorized stages and software shorten cycle time when inspecting multiple dimensions across batches.

Buying Guide (Optional)

Key Factors to Consider

1. Part Geometry & Size: Match screen diameter and stage travel to your longest part and critical features.
2. Accuracy Requirements: Consider tolerance bands; select optics and stage quality accordingly.
3. Throughput: For batch work, choose DRO with presets or CNC-assisted models.
4. Illumination: LED options reduce heat and maintenance; ensure both surface and transmitted lighting.
5. Fixtures: V-blocks, centers, rotary tables, and custom jigs improve repeatability on specific parts.
6. Data & Reporting: If you need PPAP, FAI, or SPC, plan for software connectivity and data export (CSV, PDF).
7. Environment: Shop-floor exposure to dust and vibration may require ruggedized enclosures and isolation pads.
8. Total Cost of Ownership: Evaluate lamp/LED life, calibration, operator training, and spare availability.

Indicative Price Ranges

Pricing depends on screen size, stage travel, optics, DRO/software, and fixtures. As an India-focused wholesaler, we offer scalable configurations:

• Benchtop Horizontal Profile Projectors: typically ₹1.8–3.5 lakh depending on magnifications and DRO.
• Floor-Standing: typically ₹3.5–6.5 lakh with larger travel and fixtures.

Note: Prices are indicative for planning and may vary with configuration, import content, and order volumes. Request a formal quotation for your exact specification.

Maintenance Tips

• Keep stage glass clean using lint-free wipes and approved lens cleaners.
• Periodically verify magnification and DRO accuracy with certified gage blocks or reticles.
• Maintain a stable environment—avoid direct sunlight, vibration, and temperature swings.
• Inspect and replace illumination sources per schedule; LED units require less frequent service.
• Lubricate stage leadscrews and slides as recommended; check backlash annually.
• Schedule calibration at least once a year or per your QMS requirements.

Frequently Asked Questions

What magnification should I start with?

Most shops begin with 10× for overview and 20× for general inspection. Add 50× or 100× when you must resolve fine radii, edges, or micro-features.

Do I need a CNC-assisted model?

If you inspect many dimensions repeatedly across batches and need digital records, CNC-assisted or software-integrated projectors reduce cycle time and operator influence.

Can I inspect hard-to-hold shafts?

Yes. Use centers, V-blocks, or a rotary fixture to position and rotate shafts for measuring helix angles, pitches, and profiles.

How does a horizontal projector compare to a vision system?

Profile projectors are simpler, more rugged, and cost-effective for silhouettes and edge-based features. Vision systems add camera-based measurement and automation but at higher cost/complexity.
