slitter machine hydraulic nuts for coil processing lines
Senda Hydraulic Nut is a permanent fixture, replacing the
conventional nut and retaining the high bolt load and extension in
small space envelopes where there may not be sufficient space to
use tensioners. High pressure hydraulic oil from a pump applies an
accurate, axial load to the fastener. Once the system reaches a
predetermined pressure, the operator uses a small bar to run the
nut down by hand.
Laying-off: selecting raw material
Forging: enhance the density and consistency
Annealing: increase the ductility and reduce the hardness
Rough machining: to be shaped into an intended design roughly
Heat-treatment: obtain desired properties vacuum heat-treatment
Quenching: obtain certain material properties
Cold and cryogenic treating: increase the hardness, wear
resistance, and reduce the internal stresses
Tempering: lessening brittleness and reducing internal stresses
Finish machining: to be shaped into an intended design finely
Grinding: improve the precision, Our parallelism will reach Ra1.60
