GST SPR C8 Robotic Shot Peening Machine

Shot Control, Recovery and Feed Systems

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

System ensure shot circulation within the machine, control of shot size/shape and bombardment of workpiece surface with shot.

Manipulators

• Workpiece positioner
• Industrial robot

Manipulators provide movement and positioning of shot blasting nozzles and workpiece during shot peening process. When selecting manipulators, it is necessary to take into account the workpiece geometry. Reasonably selected characteristics of manipulators ensure high process performance and quality.

Peripheral Components

• Shot blasting chamber
• Robot chamber
• Exhaust filter unit

Peripheral components include parts of equipment that ensure comfortable and safe machine operation.

Blast Generator

Blast generator supplies shot to the shot blasting nozzles. It is equipped with two chambers for storing and feeding shot to ensure continuous operation. All necessary valves are provided at the working chamber outlet for regulating the air pressure, as well as regulating and controlling shot flow.

• 2 vessels for continuous operation
• Specialized valves with feedback for shot flow regulation and control
• High precision valves for air pressure regulation

Vibratory Classifier

Shot peening process requires strict control of size of shot used. Vibratory classifier is used to separate the required size shot from the off-spec shot during operation.

• Possibility of working with shot of different sizes
• Material for housing and screens: stainless steel

Spiral Separator

During the peening process the shot may lose its original shape, which leads to unstable processing results. Specialized spiral separator is used to remove off-spec shape shot.

• Material for separator: stainless steel
• Separator self-cleaning function: standard feature
• Separator rotation function: optional feature

Shot Flow Calibration Module

At any time during the shot peening process the operator can issue a command for additional checking and calibration of set shot flow using this module. This function ensures stable shot flow in case of errors in the automatic valves operation due to variations in the shot material properties.

Carousel Positioner for Workpiece Installation

Positioner has a central axis of rotation, as well as additional satellites installed around the perimeter and capable of independent rotation around its own axis. During processing the workpieces mounted on satellites are sequentially moved into the working area when main table is rotated at a given angle.

• Satellite number: 8 pcs
• Turntable diameter: 1200 mm
• Satellite diameter: 200 mm
• Total turntable load capacity: 500 kg
• One satellite load capacity: 40 kg
• Axes control by robot servo drive

Industrial Robot

Industrial robot ensures precise and smooth movement of shot blasting nozzles relative to the workpiece surface being processed, which guarantees stable and high quality shot blasting.

• Robot load capacity: 20 kg
• Working area radius: 1650 mm
• Positioning accuracy: ±0.04 mm
• Protective cover for shot blasting

Shot Blasting Chamber

Frame of shot blasting chamber is made from the appropriate metal profile and covered with specialized sound-insulating panels, ensuring a noise level of no more than 75 dB during operation. Panels on the inside of chamber are protected from shot impacts by wear-resistant material. At the bottom of chamber there is a receiving hopper connected to the shot recovery system.

• Hinged door with positioner installed on it
• Additional operator door
• Maintenance platforms
• Separate cabin for robot placement
• Lighting and ventilation systems

Exhaust Filter Unit

Cartridge type exhaust filter unit ensures continuous air circulation inside the shot blasting chamber, as well as air purification from dust generated during the shot blasting process.

• Increased filtration area for highly polluted air
• Explosion-proof design
• Pulse cleaning system for filters
• Low noise levels during operation

Lance nozzle for holes and slots processing

This nozzle provides shot bombardment of surface to be hardened at an angle of 45° and can be rotated indefinitely, ensuring uniform processing of hole, slot or groove surfaces.

Screw Compressor

Machine can consume significant volumes of compressed air depending on the number of blast nozzles used and the required process performance. Machine can be equipped with its own compressor complete with receivers to ensure the required air flow.
