Zero Point Clamping System Q&A

Using a gauge (dial indicator or digital indicator) on the module reference surface (the side with the engraved logo), measure along the X-axis vector for calibration within 0.01mm. If a calibration plate has been purchased, it can be used for reproducibility measurements. The original factory calibration involves precise three-dimensional calibration to ensure that the horizontal axis between two modules and the X-axis of the base plate are in the same horizontal plane. Specially designed longer base plates, following international standards with an allowable tolerance of 0.01 for every 300mm, for example, a 600mm base plate has an allowable tolerance of 0.02mm, and so forth.

1.The module can be used manually or automatically for mold changing.
2.Cleaning during the mold changing process is essential for manual mold changing. Although there is a chip collection groove inside the clamping sleeve, it is still recommended to clean it with an air gun. It is advisable to wipe the module against the reference surface with a cleaning cloth.
3.It is possible to remove any iron or aluminum chips that may adhere to the chip collection groove.
4.For automation: Version 2.0 can automatically blow away and detect the partial iron chips, and it also includes a function to check for air pressure leaks. We recommend maintenance and cleaning after a certain period of use. In some cases, due to fixture design issues, it may not be possible to clean thoroughly. If there are any usage issues, please feel free to contact our relevant personnel.

1.The 120 clamping system features a patented automatic compensation device that operates through a logical loop sequence for clamping, ensuring the accuracy of the zero-point position. The linear deviation between the two points is below +/- 0.02mm (recommended +/- 0.01mm). Please ensure machining precision during design, as deviations may lead to wear during compensation, or even module damage.
2.The 62 clamping system also utilizes a patented automatic compensation device, operating through a logical loop sequence for clamping to ensure the accuracy of the zero-point position. The linear deviation between the two points is below +/- 0.01mm. Please confirm machining precision during design to prevent wear during compensation or potential module damage.
3.When machining bolt holes, attention should be paid to the perpendicularity, as a deviation of every 0.05 degrees can result in an approximate 0.03mm spacing error.
4.For the 120 clamping and internal diameter, the relative gap compensation is within 0.02mm.
5.For the 62 clamping and internal diameter, the relative gap compensation is within 0.01mm.

1.The base undergoes stress release after processing, but in special conditions with a custom base, due to the inability to achieve complete homogeneity in the crystal phase structure between materials, there is a possibility of secondary release under external forces such as excessive locking force, impact, and long-term natural deformation. The thermal expansion coefficient, which is not within the considered range, is 0.0147mm/K for steel (within 100 degrees Celsius).
2.It is recommended to operate within a working temperature below 60 degrees Celsius. Since our products are highly precise components with intricate coupling, internal use of hydraulic pressure causes oil expansion pressure to rise starting from 40 degrees Celsius. Operating above 60 degrees Celsius cannot guarantee consistent compensation, resulting in errors exceeding 0.02mm.

1.The module is made of special steel, proprietary know-how.
2.The clamping module undergoes anti-corrosion treatment, while the base plate is not rust-resistant.
3.The electroplating layer will not affect accuracy, proprietary know-how.。

Yes, it meets RoHS specifications.

1.Our Ø120 clamping system can use two types of pressure sources for releasing, and you can choose the pressure source that suits your application. The hydraulic and pneumatic operation methods are the same, but the clamping force differs. The hydraulic pressure is 2000KG per module, and the pneumatic pressure is 1000KG. (Ø62 hydraulic is 800KG per module, and pneumatic is 300KG).
2.For pneumatic use, it requires 6-8 kg/cm² (5 bar).
3.Hydraulic output range is 35~40 kg/cm² (29-34 bar), and it should not exceed 40 kg/cm².
4.Ø120 single clamping requires 67 cc of oil.
5.Ø62 single clamping requires 7.5 cc of oil."。

Two sets of positioning clamping modules can be employed, providing each hole with positioning functionality. However, when placing the workpieces, caution must be taken to avoid misplacement. Customization for dual positioning is possible, and additional locating pins can be installed beneath the fixture to prevent misalignment.

The high oil thickness will not affect positioning accuracy or locking force.

62 positioning pull pin: Additional M8.920L screw

It floats approximately 3mm. If intended for installation on the quick-change unit at the end of the arm, we would recommend not choosing an option with upward movement.

It floats approximately 1.5mm. If intended for installation on the quick-change unit at the end of the arm, we would recommend not choosing an option with upward movement.

After releasing the fixture, it tilts forward due to the elevating mechanism, causing the fixture to lack a stable support point. Therefore, we do not recommend the use of an elevating mechanism for the robotic arm.
