silverline fixtures use hydraulic components to replace mechanical parts, achieving automatic positioning, support, and clamping of workpieces through hydraulic control. They offer advantages such as high clamping force, reliable clamping, stable operation, and ease of use, and are currently widely used in scenarios such as CNC machine tools, machining centers, and automated production lines. By assembling the selected hydraulic components with the designed mechanical parts, the required fixture can be obtained. Hydraulic fixtures ensure accurate positioning and secure clamping of the workpiece at the specified position, and can reduce vibration and deformation during machining through floating supports. They can also use automatic control to press down and lift the pressure plates to clear the clamping position during machining. Hydraulic fixtures can withstand large cutting forces during rough machining, ensure accurate positioning during precision machining, and perform support, clamping, and quick release tasks that manual fixtures cannot accomplish.

silverline fixture structure

The cross-sectional shape and distribution of the magnetic poles vary depending on the workpiece. Common structures of electromagnetic chucks include rectangular and circular types. Rectangular magnetic poles are divided into longitudinal and horizontal arrangements. Longitudinal arrangement of rectangular magnetic poles is suitable for fixing larger workpieces; horizontal arrangement of rectangular magnetic poles is suitable for fixing smaller workpieces. Circular chucks are suitable for fixing ring-shaped workpieces or workpieces with complex shapes. The main characteristics of ordinary electromagnetic chucks are: magnetic flux lines are evenly distributed on the surface of the magnetic disk, the electromagnetic attraction force cannot be concentrated, and the magnetic force per unit area is relatively small; the direction of the magnetic force is perpendicular to the chuck surface and difficult to change, producing only one type of magnetic force for workpieces of the same contact area; the point of action of the magnetic force on the workpiece is limited to the contact surface between the workpiece and the chuck and cannot be changed arbitrarily. Therefore, disadvantages during machining include low positioning accuracy, insufficient clamping force, narrow scope of application, and low production efficiency.

silverline fixture features

1) Chuck holding force: Electrically controlled powerful chucks have extremely strong holding force, up to 16kg/cm², with uniform and adjustable magnetic flux distribution, suitable for various heavy-duty machining, rough machining, and precision machining; ordinary powerful chucks have weaker and uneven holding force, unable to meet the requirements of heavy-duty machining operations. 2) Machining accuracy: The holding force of electrically controlled powerful chucks does not require a continuous power supply to maintain, generating no heat during continuous operation, avoiding thermal deformation of the workpiece. Meanwhile, the strong and uniform surface holding force ensures the highest machining accuracy even if the workpiece extends beyond the table surface; whereas ordinary electromagnetic chucks require a continuous supply of current, generating heat after a period of operation, which not only causes thermal deformation of the workpiece but also reduces the chuck's magnetic force, failing to guarantee machining accuracy. 3) Performance: Electrically controlled powerful chucks can be used continuously, even for more than 20 hours per day, without any faults or need for maintenance; ordinary permanent magnet chucks show a decline in holding force after about half a year of use, while electromagnetic chucks can only operate for a few hours a day, are prone to failures, and require frequent replacement and repair of internal components. 4) Operational efficiency: Using ordinary powerful chucks requires significant workpiece adjustment time, accounting for 40%-50% of the entire machining process, and clamping positioning is prone to obvious errors, resulting in high scrap rates and very low efficiency; electrically controlled powerful chucks feature automatic auxiliary positioning, completing workpiece clamping or release in 0.3 seconds with the simple press of a button, greatly improving production efficiency.

silverline fixture maintenance

1) Check before use whether the limit dimensions are still in the correct position. 2) If the stop pin wear exceeds tolerance, it can be ground and repaired; if the baffle, pin, or locating taper pin wear exceeds tolerance, they can be reassembled, shifting the worn areas to continue use. 3) Apply anti-rust oil after use. Regular long-term lubrication maintains the life of synchronous fixtures; incorrect lubrication will lead to reduced clamping force, poor accuracy, wear, and jamming, so correct lubrication is essential. After machining, be sure to clean the synchronous fixture body and slide ways using an air gun or similar tool. When cleaning, remove the dust cover fixing screws and take off the dust cover, while opening the main jaws to the widest position to easily clean accumulated chips inside the fixture. To avoid reduced clamping force due to rust, use rust-preventive cutting oil. Remove the synchronous fixture every six months for thorough cleaning (at least every two months when machining cast iron or copper products). Check parts for damage or wear, and replace with new items immediately if severe. Lubricate thoroughly before assembly.
