GST SPR C8 Robotic Shot Peening Machine

Shot Control, Recovery, and Media Feed Systems

The shot control, recovery, and feed systems ensure continuous media circulation within the machine, precise control of shot size and shape, and consistent delivery of shot particles to the workpiece surface during the peening process.

Main components include:

• Control panel
• Blast generator
• Vibratory classifier
• Spiral separator
• Bucket elevators
• Shot flow calibration module

These systems provide accurate management of shot parameters, maintain stable process conditions, and ensure consistent treatment quality throughout the entire shot peening operation.

Manipulators

Main components include:

• Workpiece positioner
• Industrial robot

Manipulation systems ensure precise movement and positioning of blasting nozzles and workpieces throughout the shot peening process. The selection of appropriate manipulators depends on component geometry, dimensions, and process requirements. Properly configured manipulation systems provide optimal process efficiency, repeatability, and high-quality treatment results.

Peripheral Components

Main components include:

• Shot blasting chamber
• Robot chamber
• Exhaust filtration unit

Peripheral components include all auxiliary equipment required for safe, efficient, and comfortable machine operation. These systems contribute to a controlled working environment and reliable long-term performance of the shot peening equipment.

Blast Generator

The blast generator delivers shot media to the blasting nozzles and ensures a stable and continuous supply throughout the shot peening process. The system is equipped with two pressure vessels for uninterrupted operation and consistent media flow. Integrated valve assemblies at the working chamber outlet provide precise control of air pressure, as well as accurate regulation and monitoring of shot flow.

Key features:

• Two pressure vessels for continuous operation
• Specialized feedback-controlled valves for precise shot flow regulation and monitoring
• High-precision valves for accurate air pressure control

Vibratory Classifier

Consistent shot peening performance requires strict control of shot media size. The vibratory classifier continuously separates particles according to size, allowing properly sized shot to be returned to the process while removing out-of-specification media.

Key features:

• Compatible with various shot media sizes
• Stainless steel housing and screening components for durability and corrosion resistance

Spiral Separator

During the shot peening process, media particles may gradually lose their original shape, which can negatively affect treatment consistency. The spiral separator removes deformed and out-of-specification particles, ensuring stable process conditions and repeatable results.

Key features:

• Stainless steel separator construction
• Self-cleaning function as a standard feature
• Optional separator rotation function

Shot Flow Calibration Module

The shot flow calibration module enables operators to perform on-demand verification and adjustment of the media flow rate during the shot peening process. This function ensures consistent shot delivery and compensates for potential variations in media characteristics or deviations in automatic valve operation.

Key benefits:

• Real-time shot flow verification and calibration
• Maintains stable process parameters throughout operation
• Improves repeatability and reliability of shot peening results

Carousel Positioner for Workpiece Installation

The carousel positioner is designed for precise positioning and rotation of multiple workpieces during the shot peening process. It features a central rotating axis with multiple satellites installed around the perimeter, each capable of independent rotation around its own axis. During operation, workpieces mounted on the satellites are sequentially transferred into the processing zone as the main table rotates to predefined positions.

Key specifications:

• Number of satellites: 8 units
• Turntable diameter: Ø1200 mm
• Satellite diameter: Ø200 mm
• Total turntable load capacity: 500 kg
• Load capacity per satellite: 40 kg
• Axis control via robot servo drive

Industrial Robot

The industrial robot provides precise and smooth movement of shot blasting nozzles relative to the workpiece surface, ensuring consistent media distribution, stable process conditions, and high-quality treatment results.

Key specifications:

• Robot payload capacity: 20 kg
• Working radius: 1650 mm
• Positioning accuracy: ±0.04 mm
• Protective cover for operation in shot blasting environment

Shot Blasting Chamber

The shot blasting chamber is constructed using a reinforced metal frame and covered with specialized sound-insulating panels, maintaining operational noise levels below 75 dB. The internal surfaces of the chamber are protected against shot impact by wear-resistant materials, ensuring long service life. A collection hopper located at the bottom of the chamber is integrated with the shot recovery system for efficient media recycling.

Main features:

• Hinged access door with integrated workpiece positioner
• Additional operator access door
• Maintenance platforms for convenient service access
• Dedicated robot compartment
• Integrated lighting and ventilation systems

Exhaust Filter Unit

The cartridge-type exhaust filtration unit ensures continuous air circulation inside the shot blasting chamber while effectively removing dust generated during the shot peening process. It maintains a clean working environment and supports stable machine operation.

Key features:

• Increased filtration area for high dust-load applications
• Explosion-proof design
• Automatic pulse-jet filter cleaning system
• Low operating noise level

Lance Nozzle for Hole and Slot Processing

The lance nozzle is designed for targeted shot peening of internal surfaces, including holes, slots, and grooves. It directs shot media onto the surface at a 45° angle and provides continuous rotation, ensuring uniform treatment of complex internal geometries.

Screw Compressor

Depending on the number of blast nozzles and required process performance, the machine may require a significant supply of compressed air. The system can be equipped with a dedicated screw compressor and air receivers to provide a stable and sufficient air supply for continuous operation.
