Clamping workpieces - the different options
Why is safe workpiece clamping important?
1. Improper clamping
If a workpiece is clamped incorrectly, this can lead to undesirable vibrations. This can result in surface defects such as scratches or unevenness. Vibrations on the workpiece can also lead to uneven loads on the tool and there is a risk of tool breakage.
2. Insufficient fixing
Inadequate clamping of the workpiece, on the other hand, can cause the workpiece to move slightly, resulting in dimensional deviations. If the clamping is too loose, the workpiece may be ejected during machining. This can result in injuries or damage to the machine.
3. quality
Proper clamping ensures consistent quality of the parts to be machined, as the workpiece is held securely throughout the machining process.
How to choose the right clamping device for your workpiece
Tips on the use of clamping devices
Hold-down device
Workpieces are clamped directly to the worktable with a hold-down device. It consists of a curved or bent holding arm, one end of which rests on the table and the other end of which is pressed onto the workpiece using a long screw. In this way, the workpiece can be positioned completely freely.
Pull-down clamps
Pull-down clamps are positioned via the T-slots in the worktable. The workpiece is clamped laterally, leaving its entire top side free for processing. The pull-down system presses the workpiece down onto the worktable.
Clamping prisms
Clamping prisms are used for parallel clamping, scribing, aligning and checking cylindrical workpieces. Clamping prisms are mainly used for drilling, milling, grinding and inspection work. The workpiece can be additionally stabilised on the prism with the aid of clamping brackets.
Clamping claws
Clamping claws are also used in the T-slots of a milling machine. The workpieces can therefore be positioned flexibly. It is also possible to equip clamping claws with different jaws and attachments in order to machine different workpiece shapes and sizes. This means they can be used in a wide range of milling applications.
T-slot bricks
T-slot blocks serve as connecting elements. With their help, workpieces and tools such as vices can be positioned and securely clamped on machine tables fitted with T-slots on machine tools.
