The drilling machine drilling process should pay attention to the verticality of the drilling, and the main technical measures to control the verticality of the drilling are: (1) Compact and level the construction site. (2) When installing the drilling rig, the flatness of the drilling and the verticality of the active drill pipe should be strictly checked. The verticality of the active drill pipe should be periodically checked during the drilling process, and the deviation should be immediately adjusted. (3) Regularly check the drill, drill pipe, drill pipe joints, find problems and repair or replace them in time. (4) Drilling at the interface of soft and hard soil or at the inclined rock face should be done at low speed and low pressure. Found that drilling deviation, should be timely backfill clay, and then low-level drilling and low pressure drilling. (5) Drilling in complex formations, if necessary, add a grooving machine on the drill pipe.
Expanded Steel Diamond Mesh is another kind of metal screen
industry, which is also one of the main varieties of metal plate mesh. Also
known as expanded metal mesh, expanded diamond mesh, expanded metal lath, heavy
steel plate net, foot net, punching plate, etc. After the steel mesh punching
machine processing, the metal plate becomes a mesh with mesh of diamond.
Size: Opening size (mm): 2.5-50mm or according to customers`
requirements
Thickness (mm): 0.5-10mm or according to
customers` requirements
Material: High quality low carbon steel plate,
aluminum plate, SS plate, titanium plate, aluminum foil plate, nickel plate,
galvanized plate etc.

medicine, papermaking, filtering, breeding, cell network, packaging net,
mechanical facilities protection, handicraft manufacturing, high-end speaker
net enclosures, decoration, child seat, basket, basket and road protection,
foot tanker net, heavy machinery and boilers, oil mine, locomotive, million
tons of ships such as working platforms, escalators, walkways. It can also be
used for reinforcing steel bars in construction industry, highway and bridge.
Products Structure:
SWM: The length of a short diamond diagonal from a node
center to a node center
If you are curious about
how the process of forming expanded metal mesh, XinZheng is happy to provide
you with a step-by-step guide to manufacturing these products on our
state-of-the-art equipment.
1. Sheet
or plate is advanced beyond the face of the bottom die in an amount equal to
the strand width before flattening. The sheets are then fed into an expanding
machine.
2. The
top die then descends and simultaneously slits and cold forms an entire row of
half diamonds.
3. The
top die then ascends and moves one half of a diamond to the right as the base
sheet or plate moves forward one strand width.
4. The
top die descends, slits and forms another full row of half-diamonds completing
a row of full diamonds in two strokes.
5. The
die then ascends and returns to its initial position.
This process then
continually repeats until the full sheet of expanded metal is completed. This
mesh is then either cut into sheets or rolled into coils for either shipping or
additional processing.
