I use my large disc sander and stationary belt sander to “Sand to the line” after rough cutting a pattern. “I don’t know the type of motors in my tools. What I’m using is the Ridgid oscillating belt sander and the other is a large disc sander from Grizzly. At times I use a basic combo disc/belt sander and sometimes a HF 1” belt sander. They have induction motors so cannot be slowed with a speed controller but they are belted motors so are slowed a bit but not enough for the disc sander on it.
09-30-2005, 11:10 PM #2 The router speed control is for universal motors but not an option for 6×48. You have several options for regulating the speed on your sander but using your current motor with step pulleys is about it. 09-30-2005, 11:31 PM #4 I have converted several shop machines to variable speed but not a 6 x 48 belt sander but that doesn’t mean it’s a bad idea – just haven’t tried it yet. Speed control in an induction motor is available by controlling your AC line frequency.
Now, this damage may not actually be “Burn up your sander” type damage, but it will not be running in an ideal fashion. This is the reason that people in the knife making industry get variable frequency drives. Now if this is a handheld brush motor type belt sander it may work fine.
Single-phase AC you can used pulleys, different-size drive wheels, or perhaps an elaborate mechanical transmission drive. The 3-phase motors are generally cheaper than either single-phase AC or single-phase DC in comparable HP/speed ratings. The VFD can be used to produce the ‘third phase’, allowing you to put 220V single-phase in and get 220V three-phase out.
variable speed control for belt sander Related Question:
Is variable speed important on a belt sander?
VARIABLE SPEED. A belt sander excels at removing a lot of material at high speed. But you should also be able to use your sander to do controlled sanding. That’s when a variable speed motor can be helpful.
What speed should a belt sander run at?
The optimal speed for belt grinders is largely dependent on a number of factors, including type of abrasive grain, grit grade, workpiece material, and more. Generally speaking, a safe speed in most cases is 3,000 surface feet per minute. You can calculate surface feet per minute using the formula SFPM = RPM X .
How important is variable speed for a belt grinder?
Variable speed is an advantage in the learning stage and for some acrylic bone and wood applications. The standard machine is OK, if the belts for bone and wood are kept separate, avoid any contact with metal to reduce their sharpness and are kept clean with a rubber cleaning stick.
How do I choose a belt grinder?
Motor Size To effectively grind steel, you need high belt speed with the ability to exert high pressure on the belt. You won’t be able to accomplish grinding very well if you don’t have a large enough motor. As a general rule of thumb, you need 1 horsepower of motor power for every inch of belt width at 72” in length.
Can you sand a floor with a belt sander?
A belt sander will make stripping and sanding the floor quick and easy. Belt sanders have a loop of rotating sandpaper that gives quick results. A belt sander for finishing a wood floor should be a hand-held one so you can move the tool around on the surface of the floor.
How do I determine my belt speed?
Calculate the belt velocity by multiplying the circumference of the pulley by the speed of the pulley. For example, the drive pulley has a circumference of (Pi)(D2). This equals 2(Pi). The speed of the pulley is 1,800 rpm.
How do you find the linear speed of a belt?
A conveyor speed, or in this case the linear belt speed, can be calculated using the formula pi/2*D*RPM/60. In this formula, D is diameter and RPM is the rotations per minute of the conveyor. The value is then divided by 60 to convert the speed into distance per second.
How much can a belt sander take off?
As mentioned earlier, abrasive belts can only remove a certain amount of stock dependent on grit size. With a three-head sander you can run a grit sequence of 100-150-180 and remove approximately 1/32 inch in one pass.
What’s better orbital or belt sander?
A belt sander is more effective for large materials, while the orbital sander is ideal for small spaces and pieces of furniture. A belt sander works effectively on flat surfaces, while an orbital sander can work with various angles.
What grit sizes are commonly used on a belt sander and why?
Choosing the Right Sanding Belt Grit The heavier the job, the coarser the sanding belt you’ll need. 40 to 60 grit is best suited for the heaviest work. When you’re performing tasks such as smoothing surfaces or removing minor blemishes, you’re better off using sandpaper with 80 to 120 grit.
What is the difference between a belt sander and a belt grinder?
The belt grinder belt speed typically runs double from what the belt speed of the belt of a belt sander is running at. Belts grinders you generally have multiple grinding points such as the platen and the second grinding point is the contact wheel.
What kind of sanding belts are best for metal?
As high-performance belts, both zirconia and ceramic sanding belts will last longer and remove metal faster than aluminum oxide or silicon carbide sanding belts. Both belts have the ability to resharpen as they wear and both are primarily used on metal applications. In the end, both types of belts are excellent belts.
How long does it take to sand a floor with a belt sander?
It can take 1-5 days for a professional and 2-15 days for a DIY enthusiast, depending on the size and condition of the floor. For planning purposes, it would take 1-day per room for a professional and 2 days per room for a homeowner doing DIY.
How long does it take to sand a floor with a floor sander?
So how long does it take to sand a floor? If you’re using both the electric sander and the edger in 140 square-foot floor space, it will take you roughly 5 hours to do three sanding passes. Another thing you must take into account is how old your house is.
What’s the best sander for wood floors?
Unless you plan to sand many floors in your lifetime, your best choice of floor sander is the random orbital sander from one maker in particular. Unless you plan to sand many floors in your lifetime, the best choice for do-it-yourself floor refinishing is the random orbital sander.
