CELETTE Auto Body Frame Machines
Precision Engineering for Collision Repair Professionals
Founded in 1953 by Germain Celette, CELETTE is a globally recognized pioneer in automotive after-sales solutions, setting industry standards with its advanced frame machines for vehicle repair, alignment, and structural restoration. Designed for professional collision body repair shops demanding superior quality, safety, and workflow efficiency, CELETTE’s auto body frame machines integrate cutting-edge technology and decades of engineering expertise.
What Is an Auto Body Frame Machine?
An auto body frame machine, also called a frame straightening machine, is specialized collision repair equipment that secures a damaged vehicle, measures chassis and body dimensions against factory specifications, and applies controlled pulling forces to restore the structure to OEM tolerances.
The equipment consists of several integrated components: a bench or platform that supports and anchors the vehicle, pulling towers that apply directional force to deformed areas, anchoring fixtures that secure undamaged sections, and measuring systems that verify dimensional accuracy throughout the repair process.
CELETTE’s frame straightening machines are designed specifically for collision repair body shops working on both unibody and body-on-frame vehicles. Unibody construction, where the body and frame form a single integrated structure, dominates modern passenger vehicles and requires precise, distributed force application during straightening. Body-on-frame vehicles, common in trucks and SUVs, present different structural repair requirements that CELETTE equipment accommodates through appropriate anchoring and pulling configurations.
Unlike generic repair equipment, CELETTE’s auto body frame machines reference OEM dimensional data to ensure repairs restore vehicles to factory specifications rather than arbitrary measurements. This precision is essential for modern vehicles, where structural accuracy affects the safety system’s function, suspension geometry, panel alignment, and ADAS sensor positioning.
How Frame Straightening Works:
Step-by-Step
Shop owners often ask what is a frame machine and how it works in practice. When a shop invests in a frame straightening machine, the repair follows a consistent sequence built around measurement, and the steps below outline it.
- Inspection and measurement. Technicians mount the vehicle and measure key reference points using electronic or laser systems, comparing readings against OEM dimensional data. CELETTE’s Naja 3D and EAGLE systems generate a pre-repair report that sets the baseline.
- Anchoring. Undamaged sections are secured to the bench with anchoring clamps and fixtures, holding the vehicle stable during pulling.
- Jig setup. Dedicated or universal jigs (MZ/MZ+ and Cameleon) are positioned at factory reference points, so the structure is pulled toward true OEM locations.
- Controlled pulling. Pulling towers apply directional force to deformed areas. Force is applied in stages and re-measured as the structure moves back toward specification.
- Verification. Measuring systems confirm the corrected dimensions match factory tolerances, and a post-repair report documents the result.
- Handoff for finishing. Once the structure meets OEM specifications, the vehicle moves to panel work, refinishing, and any required ADAS calibration.
Frame Types
Modern vehicles use several structural designs, and a frame machine accommodates each one through the right anchoring and pulling setup.
Frame type | Description | Common vehicles |
Unibody (monocoque) | Body and frame form one integrated structure with built-in crumple zones. This design dominates modern passenger vehicles and requires precise, distributed pulling force. | Most passenger cars, many crossovers and SUVs |
Body-on-frame (ladder frame) | A separate frame supports the body and drivetrain, giving rugged load capacity. | Pickups and off-road vehicles such as the Ford F-150, Toyota Tacoma, Toyota Tundra, Jeep Wranglers, and Mercedes G-Class |
Mixed-material and aluminum | High-strength steel and aluminum structures used on many current models for weight reduction, calling for material-appropriate benches and tooling. | Various late-model cars and light trucks |
CELETTE equipment covers these structures. The Sevenne, Rhone, and Griffon benches handle unibody and body-on-frame work, ladder frame anchoring clamps and the Tetrac+ system secure separate-frame trucks and SUVs, and heavy-duty systems such as the Vegamax rack extend capability to commercial vehicles. For aluminum and high-strength steel construction, CELETTE’s tooling includes the WedgeClamp aluminum floor-rail system and aluminum-capable panel and welding equipment.

Frame Straightening and ADAS:
What Shops Should Know
A common question from shops handling newer vehicles is what is a frame machine and how it fits into ADAS-equipped repairs. The connection is sensor accuracy. Advanced driver assistance systems (ADAS) rely on cameras, radar, and ultrasonic sensors that sit at precise angles relative to the vehicle structure. According to I-CAR’s collision repair guidelines, if a vehicle equipped with ADAS is involved in a collision, calibration will likely be required, regardless of the impact severity. Structural repairs that affect sensor mounting points, including frame straightening, unibody repairs, and panel replacements, call for recalibration.
This is why structural accuracy comes first. ADAS calibration requirements are defined by OEM procedures based on manufacturer specifications, not by dashboard warning lights. A frame machine that references factory dimensional data gives shops the accurate structural foundation those procedures depend on. CELETTE benches restore vehicles to OEM tolerances and produce pre- and post-repair measurement reports that document structural accuracy for the calibration step that follows.

CELETTE builds each solution around a shop’s vehicle mix, repair volume, and floor space, so exact pricing is provided on request through a consultation or online quote.
Q: Do I need a frame machine to repair ADAS-equipped vehicles?
A: Structural accuracy is a prerequisite for ADAS calibration. If a collision has moved a vehicle’s structure, a frame machine restores it to OEM dimensions so sensors return to their designed positions, and calibration is then performed to the manufacturer’s procedure. I-CAR describes ADAS calibration as part of a proper, complete repair and a final quality check that confirms safety systems function before the vehicle returns to the customer.
Q: What is the difference between unibody and body-on-frame repair?
A: Unibody construction integrates the body and frame into a single structure, common on modern passenger cars, and calls for precise, distributed pulling force. Body-on-frame vehicles, common in trucks and larger SUVs, use a separate frame that supports the body, and repair uses anchoring and pulling configurations suited to that frame. CELETTE benches accommodate both through the appropriate fixtures and clamps.
Q: How long does frame straightening take on a modern vehicle?
A: Timing depends on damage severity, parts availability, and calibration. The hands-on straightening work can often be completed in hours, while the overall structural repair typically takes one to three days for most vehicles once repairs begin. On more severe damage, the structural phase can run two to five business days, and the full collision repair including body, paint, and final ADAS calibration usually spans two to four weeks.
