Petrini systems for workpiece positioning
Rotary Tables and Workholding Systems for Mould Makers
Manual and motorised solutions for clamping, positioning and rotating moulds and workpieces, bringing every surface into the best position for the operation.
Developed from the mould maker’s experience
The workpiece in the right position, the operator in the best working conditions
Petrini tables were developed to meet the practical needs of mould construction, maintenance and polishing. The principle is simple: the workpiece must be securely clamped and brought into the most accessible position, without forcing the operator into awkward postures or repeated repositioning.
The range includes compact bench-mounted systems and higher-capacity rotary tables, available in manual or motorised configurations. The same solutions can also be used for assembly, welding and any operation requiring controlled access to several sides of the workpiece.

Adjustable Petrini Stampi Ø 300 workholding table
A compact bench-mounted solution for bringing the workpiece closer, rotating it and tilting it during precision operations.
The perforated circular top allows workpieces, jigs and fixtures to be mechanically clamped. The handwheel-operated manual system changes the table angle and brings the surface being processed into the most comfortable and accessible position.
- Manual positioning
- Ø 300 mm perforated top
- Compact bench-mounted design
- Base prepared for anchoring
- Suitable for multiple operations
- Exclusive GDS distribution
A range for different requirements
From a compact workstation to handling larger, more demanding workpieces
Ø 300 bench-mounted adjustable table
Designed for smaller moulds and workpieces where stability, positioning and a compact workstation footprint must be combined.

Manual rotary tables
Robust solutions for clamping and positioning larger workpieces while keeping rotation under the operator’s direct control.
Request the right configuration
Motorised rotary tables
For cycles requiring more continuous or repeatable workpiece rotation. The configuration is defined according to the workpiece dimensions, weight and intended process.

Why position the workpiece during processing
Surface accessibility
The working area can be brought closer to the operator and the tool, even when complex geometries are involved.
Greater control
A favourable position improves visibility and enables more precise control of pressure and working direction.
Fewer repositioning steps
The workpiece remains securely clamped while its orientation changes, reducing repeated lifting and clamping operations.
Ergonomic workstation
The operator can work in a more natural posture, especially during long polishing and manual finishing operations.
Not only for moulds
A versatile support for many operations
The ability to clamp and position the workpiece is useful whenever the quality of the result depends on surface accessibility and workpiece stability.
GDS can assess the workpiece dimensions, weight, type of operation and available space together with the customer, identifying the most suitable manual or motorised solution.
Mould polishing and finishing
Easier access to flat surfaces, cavities, radii, ribs and inclined surfaces.
Welding and repair
Positioning of the area to be welded for improved visibility, control and continuity of the operation.
Assembly and maintenance
Stable positioning of the workpiece during assembly, inspection and reworking.
Precision operations
Deburring, lapping and manual operations requiring access from multiple angles.
Selection guide
Which type of table should you use?
| Requirement | Suggested solution | Why |
|---|---|---|
| Compact workpieces and bench work | Petrini Stampi Ø 300 adjustable table | Compact footprint, clamping on the perforated top and manual adjustment of the orientation. |
| Larger or heavier workpieces | Manual rotary table | Dedicated structure and higher load capacity while maintaining direct operator control. |
| Frequent rotation or repetitive cycles | Motorised rotary table | Assisted movement and a configuration designed around the workpiece and the process. |
| Non-standard requirement | GDS technical assessment | Dimensions, weight, clamping points and operating methods are analysed before a solution is proposed. |
Frequently asked questions
Information about rotary and workholding tables
What is an adjustable workholding table used for?
It is used to clamp a workpiece and change its position without removing it from the workstation. It provides better access to surfaces during polishing, finishing, welding, assembly and maintenance.
Does the Petrini Stampi Ø 300 table rotate and tilt?
Yes. The manual system allows the top to rotate and tilt, bringing the surface being processed into the most accessible position. The available angles and locking methods are specified in the product’s technical documentation.
How is the workpiece secured?
The circular top has a series of holes for mechanical clamping. Clamps, jigs and accessories must be selected according to the workpiece geometry and weight.
Are these tables intended only for mould makers?
No. They are especially suitable for mould processing, but can be used in any operation requiring a stable, rotatable or adjustable workpiece, such as welding, assembly and mechanical maintenance.
Can GDS recommend the most suitable table?
Yes. To assess the most suitable solution, it is useful to know the workpiece dimensions and weight, clamping method, required movements, frequency of use and available workstation space.
