How to choose Structural Steel Fabricating Band Saw?

Band saw machine has many type, they differ in function, configuration, features etc.

Jinan Supertime Technology Co.,Ltd with over 20 years experience in design, professional manufacturer DJ series structural steel fabricating band saw. 

But many users become dazzled by various band saw machines. Here is the question: How to make reasonable selection of band saw machine?

1. Consider your costs and precision:

If high precision is required, then material feeding trolley is much better than roller.

Band saw + beam drilling machine = complete production line

2. Consider workpiece parameters:

Since band saw machine is mainly used for structural steel cutting, If you say: “I need this band saw machine, please give quotation.”

Hey, No hurry! what machine model is proper for you? In this case we need to know the following parameters, such as

beam sectional size, length,

section shape and thickness,

if transverse table is necessary...

3. Consider saw blade longevity:

. Hydraulic tension device, saw blade keeps good tension force during high speed movement, prolongs saw blade longevity;

. Tension regulation according to H beam size;

. Automatic saw blade detection device, machines stops automatically when blade ruptures;

. Power rotary brush can remove chips, keeps saw blade clean.

How To Choose Drills?

To drill holes 0-40mm in diameter, we can choose carbide drill, with good solidity and drilling performance, generally applied in high speed drilling equipment, in boiler, bridge, shipbuilding, wind power, nuclear power etc. In comparison with twist drill, efficiency is increased 3 times.

And sometimes when drilling holes it’s not necessary to cut off all the metal with chips and shaving. So the most economic way is to use trepanning drill, by driving drills into socket and turn the shank, round slots can be made by removing the metal in form of disk and leaves a hole on steel plates.

This method can reduce material waste and machine power consumption. When the sample is removed for performance testing, the trepanning drill is the unique tool which can’t be replaced by others.

ADVANTAGES:

Drill as deep as you want. There’s virtually no limit to the depth of the hole.

Save core for reuse. As the trepanning tool feeds into the work piece, the trepan bit or insert cuts a groove the width of the bit and a solid metal core remains. Because only the width of the bit is cut, trepanning is faster and more efficient than drilling with spades or indexable drills. Remove and reuse the metal core for other operations and cut your material costs even more.

Works on a variety of equipment. Muskegon Tool can develop your trepanning tool to work on horizontal boring mills, engine lathes, turret lathes, deep hole boring machines and other machines.

Simplifies maintenance. Trepan bits and wear pads can be replaced without replacing the head and stem so you spend less on tooling and labor costs. Shank type bits are stocked for immediate shipment.

One Chart Makes Beam Drill Line Efficiency Clear

CNC H beam drilling machine is widely applied in steel structure, construction, building, stereo garage, elevator, bridge and other industries.

Choosing machine model according to beam size. 

For stereo garage and elevator industries, H beam size is usually no more than 400x400mm, you can choose SUPERTIME SWZ400 series beam drilling machine. 3 or 9 spindles for choice, 9 spindles for drilling holes with different parameters and doesn't need to change drill bits.  

If beam size is max. 1000x500mm, SWZ1000 is the right model. For beam size max. 1250x600mm, you can choose SWZ1250.

These two types of machine have 3 different processing efficiency. The drilling efficiency comparison is shown below.

Drilling beam size over 1250mm, SUPERTIME design department introduced gantry movable type drilling machine, advantages are: bigger bearing capacity, good rigidity and shock resistant, gantry flexible movement, precision, reduces bed length, saves space.

Panama Railway Construction, Chinese Laborer Contribution

13-th June is a date for memory, president Panama Juan Carlos Varela announced diplomatic relations with PRC. Meanwhile he mentioned the first railway in Panama was built by Chinese laborers. And this is the infrastructure construction of Panama Canal. 

Panama canal connects Pacific ocean and Atlantic ocean. At the beginning of the 19-th century, with development of transportation, railway construction became an ideal solution for connecting the two oceans. In 1846, USA defeated France and UK, and got right to build Panama railway, whose total length is 76.6km.

In 1850, project began, however because of local harsh natural environment, thousands of labors died of infectious diseases. Labor shortage became the biggest problem in railway construction.

Government recruited hard working Chinese people in Guangdong and Fujian provinces. They worked without complaint, worked longer time, without moments of smoking or chatting, started work immediately after having lunch. Hard work was approved by employer. However...

This irritated labors from Ireland, according to labor contract, Chinese labors deserved salary of 25 dollars, deducts meals cost, transportation cost from China to Panama and other daily costs, they received only 4-5 dollars a month.

Some labors suffered from depression because of different traditions and homesick, as a result, over 100 Chinese commited suicide.

Under each railway sleeper of 76km length in total, buried one Chinese labor...

Inspection Of CNC Drilling Machine For Angle

Nowadays, in steel tower design, big size and high strength angle is more popular and widely applied. According to GB2694-2010, when steel angle thickness over 8-20mm, angle drilling technology is adopted.

Jinan Supertime Technology Co.,Ltd introduced

in 2007 JX2532 CNC drilling marking machine for angle

in 2009 designed high speed drilling machine for angle

in 2012 designed high speed drilling machine with ATC for angle

Angle drilling machine advantages?

Delicate and reasonable structure; Ensures angle processing safety and reliability; Complete electrical device, hydraulic and pneumatic systems etc;

Dispersed spares are marked obviously for joint and installation convenience; Non-existence of abnormal vibration or impulsive sound during machine running;

Welded and forged metal parts, for example marking unit, worktable, base, cylinder, drill heads etc, should pass eliminate internal stress treatment;

CNC system should meet angle processing demands, with programming and self diagnostic and alarm functions; High positioning and re-positioning precision.
