Spindle damage from reduced clamping
power can quickly require regrinding the spindle to bring it back into service.
with Unilock occurs when the clamping
module closes onto a clamping
pin via spring force and radial pins.
When determining the holding capacity necessary for a clamping
solution it is essential to understand the difference between holding capacity and exerting force.
The hybrid design delivers the combined capabilities of hydraulic clamping
with most of the energy savings, quick response, high position repeatability, and fast injection of an all-electric.
If only the final die is to be changed, this can be done quickly by partially releasing the die clamping
Standard features: Closed-loop clamping
and injection control with variable-volume pump.
Because industrial clamping
devices are more costly than strap clamps and fasteners, it is important to maximize workholding efficiency.
Toggle clamps are rated by clamping
force and holding capacity.
The clamps were so easy to install," recalls Mr Leland, "that we could mount them in all the critical areas where added clamping
force is desirable.
One way to avoid variability in clamping
is to use power clamps, which rely on either pneumatic or hydraulic pressure for operation.
tons) employs an electric injection unit and two-platen hybrid-electric clamp, which uses hydraulics for final clamping
in the center of the platen as well as for nozzle touch and core pulls.
This article gives the facts about modern hydraulic clamping
