new developments in sanding technology.

Task ability, reduced settings-
Over time, it has become easier to produce high-quality end products, and industry experts attribute this result to recent technical updates on the feeder Sander.
Wood and wood products investigated the grinding machinery dealers and manufacturers on new developments in polishing equipment technology.
Consensus: The quality completion of the final product depends on an appropriate equation involving the polished material, the machines and methods used in the sanding, and the time and effort involved in the process.
One question is: \"What are the new developments in equipment technology and how can they help users improve production efficiency?
\"Here are some edit responses from sandingequipment vendors to this issue.
Harold capann, National Sales Manager, Timesavers: \"In Western sanding technology, there are three types of combined planing knife/Sander, feeder track Sander and sealed Sander.
\"The combined planing knife/Sander uses a knife head that follows one, two or more grinding belts.
Knife head in the first bracket: reduced horsepower requirements and grinding costs, and increased feed speed
Speed rates and more accurate tolerances are achieved.
In the past, sticky
Use 36-planning panelgrit abrasives.
This requires a grinding sequence of 60/100/120 to remove scratches.
The surface of today\'s knife head is smooth and takes about 0. 010-0. 012-
Inch stock removed, so 120-
Use a grinder.
\"The recently added fed-through track Sanders is a combined machine that uses broadband sand heads, followed by rail heads, followed by denibbing brush units.
Track Sanders is mainly used to remove scratch patterns from belt sanding and/or stroke sanding.
The second use of this special machine is sealing/painting polishing.
\"The woodworking industry, together with many major machinery manufacturers, is constantly developing new and improved sealing sanding methods.
Sealed sanding can be done by using widebeltsanders, brush machines, hand sanding, rotating brush and by rail sanding.
It has been seen and further developed that denibbing of materials in white wood state by any of the above methods has greatly improved the product before dyeing and sealing.
The surface with proper preparation reduces the amount of human work used in subsequent processes.
Dean Sager, sales manager, Tekna Machinery: \"Computers increase productivity by reducing operator groups
Wrong time and operator.
Save computer programs of all different materials to beent-through Sander, operator group-
The boot time and error are greatly reduced.
No more manual settings
Several differences in running each piece of material on the machine.
It is all handled by calling a single program for a specific material, which is pre-processed
Set everything on the machine.
\"The electronic segmented pads greatly reduce the sand holes of the veneer and lacquer, which in turn greatly improves the operator\'s productivity by reducing operator errors, material rework and material handling.
Scott crissum, Costa and crissum machineryInc.
The problem is always the same.
It seems that the answer for most sand suppliers is always the same: computer control, electronic split board units, etc.
Instead of trying to take the broadband Sander as a whole, however, why not eliminate these problems before they start the operation of the broadband Sander?
\"Manufacturers are beginning to realize that if the panels are fairly flat, if the overall panel tolerances are tighter, they will not only see a significant improvement in the quality of the sanding, but also a significant improvement in other processing operations.
The answer to this question is the core calibration.
\"If the manufacturer is aware of the importance of recalibrating, then there is no additional cost to copy the head on the combined machine.
If the panel is flat, there is no need to copy it.
In short, the tolerance of all machines throughout the manufacturing plant will be greatly improved.
\"The last thing to consider is the final product.
If the panel is processed from the beginning of the operation, the finish will be more uniform, thus helping to produce the best possible finish. \"Stephan W.
Waltman, vice president of sales and marketing and international product manager-
\"As in most areas of the woodworking industry, the use of electronic control technology has made woodworking workers more productive, from simple terminals to controlling belt speed and feed speed, then to the integration technology that can remember the unit --
Upgrade the entire machine by part number or bar code.
By using this electronic aid, the grinding technician can greatly reduce his equipment
Improve time and quality.
Mike Hammer of Sunhill Machinery: \"We are in 15-inch wide-
Belt Sanders with open design, with smaller footprint and smaller power requirements.
Technological progress means [+ or -]0. 001-
Inch accuracy of side to side.
The adjustment of the contact roller hardness means extreme precision when grinding, even for laminated materials with very close tolerances.
\"We believe that keeping pneumatic tracking can provide reliable performance through reliable technology compared to the high service and replacement parts costs associated with electric power
Eye tracking system. Keeping the 15-
Inch sanding machine is simple, there is no table plate and single head, reduce the cost, and the cost is very high
Small shops can buy high quality sanding equipment at a reasonable price.
\"Improvements to the dust removal design, closer to the full head of the throat --
The length of the contact roller means more efficient removal of waste, reduction of dust in the workshop, and a healthier workplace.
\"Chris Deda of Deda company
: \"The grinding beltunits technology used in the past for contour sanders includes rigid design of the grinding rod mechanism on the unit.
The rigidity of the sand cushion Inlet has a significant effect on the edge.
In other words, the pads remain in the same rigid position and do not follow the natural contours of the combustion profile.
Belt changes through the material.
\"Today\'s pad mechanism is more tolerant and more satisfactory.
They can be adjusted according to the outline of the edge.
This produces a smooth rather than a calibration effect on the edge. \"Set-
Until the correct positioning of the grinding plate is obtained, the maximum time on the grinding plate is usually a process of trial and error.
The new forgiving design usually allows the operator to get good sanding work on the first few test pieces.
\"Seat belts can now be used to polish the edges of the cathedral and other shapes.
Where possible and economical, the grinding tape should be used to polish surfaces without complex details.
In the past, most of the grinding on the edge of the shape was done using the grinding disc unit.

The use of technology or hand polishing will reduce time constraints and labor costs and increase productivity and production capacity.
Doug Armitage, technical sales manager, Force Machinery: \"Wide-
The design of the cross belt sanding machine has had a huge impact on the way the woodworking looks at surface improvement and quality while polishing.
The cost of this technology has dropped to the range of smaller manufacturers, the machine is easy to operate and consistent in uncalibrated materials.
\"In many applications, the traditional Sander has been upgraded, manual and track sanding has been completely eliminated, and the new polishing method can achieve measurable results on the bottom line, there are obvious improvements in quality and consistency.
\"The carpentry I spoke to reported that in order to take advantage of the new machine, they changed the actual function of sanding in production.
It\'s not always easy.
Traditional sanderdesign focuses on the removal of inventory.
The modern polishing Sander is mainly dedicated to providing clear surface quality for the application of modern polishing materials.
This is very different from yesterday\'s design of the resistance standard.

Match the machine feed rate and sand size to get the best finish on the hinge of the broadband Sander, depending on the type of material being polished, and the end use of the material.
\"From customers to customers, the best completion is very subjective,\" said Mike Hamer of Sunhill Machinery . \".
\"The biggest advantage of broadband is that the large area of the belt, coupled with beltoscillation, means that the work is overheating and burning when using the fine grille (180-220)
Even in materials with knots or variations in thickness, this is not a problem.
In most cases, experience and material knowledge on the machine is the only reliable guide for the customer to get the best finished product.
\"With this in mind, to achieve the best machine performance in the best possible finish in the final product, it is necessary to understand the materials being polished, the machines being used, sand properties of the Belt and final use of the finished product.
Scott Grisham of Costa Grisham machinery said: \"The bottom line is that there is no \'rule of experience \'. \"
\"The most important thing, however, is left out of the equation: cutting speed.
Actually, not the theory, all the things that are polished need different cutting speeds.
This can also be traced back to what kind of sandpaper the end user uses.
He continued, \"the best and only guideline to follow is: achieving the best possible completion in the broadband sanding sector depends entirely on one thing, that is, the end user, the supplier of broadband sanding sand paper and the supplier of finishing materials.
Only when these four groups work together can we achieve the best results.
Dean Sager, sales manager at Tekna Machinery, agrees, \"it depends on what you polish.
\"When grinding solid wood with 36 grains of sand and calibrating a large amount of wood,\" Sagel said, \"you will move at the slowest feed rate.
When the finish is polished, you use a very high grits of 240 or more, and the table top feed rate will be very high so that the grinding surface will not heat up. \"Harold K.
Kapaun, national sales manager at timeshare explained, \"most broadband Sanders are equipped with a percentage of the motor load meter to monitor the amps used by the main motor.
Experienced operators can judge whether each worn head has removed the correct stock count by watching the percentage load meter.
The percentage load meter is also used as a tool to avoid overloading the given grinding particles, resulting in an immediate load and/or damage to the grinding belt.
Kapaun added: \"It is recommended to achieve the highest grinding belt life and reduce electrical costs where possible (back to back)feed product.
By transporting the material back to toback, the conveyor belt does not see the normal front and rear \"impact\" load caused by the workpiece.
There is a smooth transition from the first to the second.
By reducing the impact load on the conveyor belt and reducing the surge that will occur if the process is not used, the highest possible wear life is achieved with the lowest power consumption.
Kapaun also added, \"it is recommended to skip no more than one grinding particle from widebeltsander\'s first head to the second.
Without skipping more than one grinding particle, the grinding particles below can remove the scratch pattern of the previous grinding particles.
In recent times, Gao
The end customer will not skip any rough grits.
An example is on a typical four-head belt sander, where the sand sequence will be 10/120/150/180 or 120/150/180/220 in order to obtain the best possible sand surface.
\"According to Doug Armitage, technical sales manager of Force MachineryCo.
, \"At a given grinding speed, the feed speed of the wide belt is not related to the finish compared to the material type and the grinding type.
We train operators to run at the highest speed that can be affordable in any particular production situation.
At a lower feed rate, the belt life is affected, and in the case of high inventory disassembly, improper belt loading can cause surface defects. \"Stephan W.
Waltman, vice president of sales and marketing.
StilesMachinery said, \"it\'s hard to give any (specific)guidelines.
Belt speed has a direct relationship to the quality of the finished product, but if cross belts are used, this must be evaluated in a different way.
Regardless of the granularity of the cross belt, the operator must adjust the belt speed to match the overlap required to remove the stock enough.
It always depends on the process parameters and the expected results. \"-J. R.
