Production cut-
With the focus on the steering saw system, the saw operation has changed dramatically.
They are made around more and faster cutting machines that improve accuracy, shorten cycle times, improve logistics, and make the operator\'s work safer and easier.
One of the major changes is
Transfer the operation of the production workshop to the unit.
There, with the help of complex nc controls, they have become the backbone of metal processing operations and are valued for increasing productivity by investing in new equipment.
There are four basic types of saw beds: Cutting
Saw, saw (cold)
Saw and saw.
There are two basic types for all types: automatic operations (including inventory index and positioning) and manual operations.
Most automatic machines can also be operated manually.
There is also a common feature of these four basic types, that is, the saw blade.
Cold round saws are used to require a better finish, but the material size they can cut is limited.
They are very competitive in 1 [inch]to 3[inches]
Range when milling finish is required.
They are also used for non-ferrous metal saws or cutting profiles to reduce burrs.
The band saw machine has represented 70% of the factory\'s production saw due to its low cost combinationper-cut-
Simple maintenance, easy to use, able to produce rough and cutting
Cut the film quickly.
Although bandmachining is not always the fastest method, its cost parameters meet the different volume and size cutting
Off requirements for a given operation.
These can be cut from practicaloff of medium-or light-
For heavy-duty production power saw, the bar material of the heavy-duty workpiece is relatively small.
One of the features of the belt conveyor with excellent cost and performance parameters is its economical narrow width tool, which produces the least waste of material and the required horsepower compared to any other saw method
For the sake of the workload, it is extremely important to match the horsepower of the machine with the width of the blade.
However, it is also important that the machine structure, head support and bearings, as well as the saw rail, be used to eliminate vibration that reduces precision and increases the wear of the saw blade.
There are basically two band saw machines: profile band saw and horizontal and vertical cutoff machines.
The Contour machines are running from very simple, low-cost devices to very expensive systems with power meters and automatic loading.
In general purpose applications, profile belt machines can cut plastic, wood, paper and fiber materials using blades from 1 [inch]down to 1/16[inch]
Complex cutting.
Typically, they can be configured as machines for special purposes, for example, graphite electrodes for cutting EDM machines using thin diamondcoated wire. Band cut-
The machine has a flat and vertical design.
The most common is the horizontal scissors.
Type design as a mechanic at one end of the head assembly.
In some cases, the head can be mounted to cut at an angle.
Another Level
Type the machine is a guillotine type or double column-
Maintain the style of the blade horizontal position.
Vertical cutting-
Off machine can also be configured as anglecut with head tilt.
These two types of applications are diverse.
General scissors-
Use type horizontal where barstock is the largest percentage of work.
In the production power saw, the cutting rod can be nested.
Where it is difficult to locate the structural material or where the work constitutes the cutting of most of the material, vertical cutting
Should consider leaving the machine. Cut-
Off machine benefits from the increasingly complex process of nccontrol, which can be programmed for multiple jobs and called upon notification.
The Plc eliminates the need for manual positioning and relies on the skill and judgment of the operator.
The control can indexate the length of the desired workpiece and position it correctly on multiple parts through automatic cut compensation for more accurate cutting.
The purpose of the control is to integrate the material movement with the saw and sequence drive for positioning, clamping the material and lifting the first class action.
The cutting tolerance of the band saw is limited only by the flexibility of the knife holder that acts as the guide arm.
The shape of the teeth and the new coating improve the finish, but usually within the range of 250 rms.
Of the most 3 [workpieces], fine finish less than 100 rms is possibleinches]
Use a circular cold saw.
There are three basic types of band saw for cutting
Off: carbide, bimetal hs and wc. Bi-
Metal hs saw blade is the most suitable choice for most production cuts
Applications involving almost all black cutsoff jobs. But carbide-
For hard or very wear-resistant materials, it may be necessary to tilt the blade, the carbon blade may be suitable for non-ferrous and highly worn materials
Grinding applications.
For a given job, the best blade is the one that is able to provide specific precision and finish requirements at the lowest cost.
Bladecharacteristics has decided on this, which must be taken into account when choosing a combat saw blade for the work at hand.
The saw blade has five basic features: Tooth type, pitch, width, specification and group.
Each time a blade is selected, at least some of them must be selected.
Dental type: carbon alloy and bi-
The metal blade has three types of teeth, supports, claws and precision;
Cemented carbide is provided in its own special form.
Precision is the choice of most tooth shapes.
Claw teeth usually have the best curing rate.
Precision and support are preferred for the best finishes.
Spacing: the number of teeth per inch selected mainly for material thickness.
Thin materials require precise spacing or more teeth, while thick materials are most effective with or less tooth spacing per inch.
In order to perform well, the blade selection should always have at least two teeth at work, preferably three;
For the thin material on the contour machine, use the teeth as much as possible.
Width: the width of the blade measured from the tip of the tooth to the back and the inspection tool determine the beam strength, thus determining the blade\'s ability to maintain accuracy and high saw speed.
For profile work, always use the widest blade with the required spacing (thin work only)
This will cut the minimum radius required and the machine can handle it.
Inspection tool: the thickness or inspection tool of the new blade has been standardized on most blades. Blades 1[inch]wide are 0. 035[inch]gage; 1[inch]to 11/4[inches]blades are 0. 042[inch]
Gage and 1 1/2 [1 [inches]and some2[inches]are 0. 050 gage.
When the blade width is limited by mechanical capacity, the strength of the beam can be increased by using the same blade width.
In order to see large workpieces with extremely high precision, the answer is often a heavier gauge band.
Offset the teeth on the band saw blade to leave a gap on the back of the band saw blade so that it can be cut freely without binding.
The amount of offset is called the group of blades, which determines the amount of cuts.
Raker, wave and straight are three basic modes.
Raker is the most commonly used, with a braces on the right, a braces on the left, and a tooth that is not fixed.
The sawmill system can be equipped with accessories, including electric belt brushes, for flushing from blades, chip blower, automatic chip conveyor, mist coolant assembly, and even saw blade welders on contour machines.
