as a general rule, you will run 36 grit vsm ceramic plus belts at a higher rmp and 120 grit vsm ceramic plus belts at a slower speed. you can purchase vsm ceramic plus belts on our nexus grinders website. surface feet per minute here is a simple grid to determine your sfpm based on a 4″, 5″ or 6″ drive wheel for a 2 x 72 belt grinder.
dec 31, 2011. messages. 3,348. dec 19, 2016. #2. some of the ceramic are designed to run as high as 6,000+ sfpm, and even up to 7,000 sfpm. i wouldn't want a grinder to turn that fast, but some folks do use some very high . 4,000 sfpm is my max and it will throw some sparks! ken h>.
to calculate the speed of conveyor belts ,we must know the circumference of drive roller and revolutions per minute. the product of the perimeter of the roller and revolutions per minute gives us the speed of the conveyor belts. if suppose we have...

you can also use the calculator to find approximate sfpm on disc grinders. to calculate disc grinder enter motor rpm and select the area you are using on the disc pad. measure from center and enter in the wheel diameter box. * 0% set to minimum of 10% speed from factory. 562 - 4140 rpm - 5' contact wheel.
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 .262 x tool diameter.
grinding wheel speed calculator: all norton grinding wheels are marked with a maximum operating speed in rpm. most machines, and especially cnc machines, use surface feet per minute (sfpm) as an input, which requires operators to do the conversion.
belt speed calculator. i get asked a lot about what speed a motor with a drive wheel and a ratio of pulley 1 and pulley 2. it's a lot of stuff to figure out especially if you factor in a vfd driving the whole lot. being shut out of the shop for another cold week where the temperatures were dipping to the -30°c (-22°f) mark.
jan 19, 2018. #1. i am in the process of building a 2x72 belt grinder. all welded construction, using many components available online. main question is motor speed. i have two motors both 1hp 110vac. one at 1800rpm and the other at 3600rpm. neither is totally enclosed fan cooled. but since i have them now, i will use one or both as time goes on.
some grinders require the motor to be face mounted and the jack shaft is not possible. for an 1800 rpm motor i recommend a 7' drive wheel. this will get your belt speed closer to the abrasive manufacturer's specified speed. most belts do a good job around 4000 to 5000 feet per second. i have a tool for figuring out your belt speed here.
pulley calculator. rpm, belt length, belt-surface speed, animated diagrams metric. for inch versions, directly under the main tab is a smaller 'inch' tab for the feet and inch version. drop down menus have m for metric versions. if you know any 3 values (pulley sizes or rpm) and need to calculate the 4th, enter the 3 known values and hit
bba20 - 2' x 72' belt grinder the 20” contact wheel reduces the annoying joint splice and chatter from the platen and will improve overall function and finish of your knives. burr king’s bba20 belt grinder was designed with the single intention of giving you the largest contact wheel grinder on the market.
the infinitely adjustable variable speed motor allows precise control and optimum grinding speed for the 2 x 72-inch belt. maximum belt speed with the 6-inch drive wheel allows for belt speeds up to 4500 sfm. by changing to an optional 8 or 10-inch drive wheel the belt speed can be increased to 6000 & 7500 sfm, accordingly. warranty:
the motor is a 200 mm grinder with a 8 inch wheel. and a flat 3 inches wide by 5mm thick and 8 inches long .. all that is missing is the actual belt, 2x72 inches.
i'm not sure what the max speed rating would be on the belt it's self but most beltsanders that i have used are 1400-1500 ft/min max speed. if you bought new belts then they may have a max speed on the package but if not i'm sure you could contact the co. and they could tell you, espeacially if they are a high quality belt.
i use three belt grinders a lot and for all metal work pay a lot of money for belts that i have found that will do the work i want right. that includes a commercial variable speed grinder, a comercial fixed speed grinder and a home made variable speed grinder set up with small contact wheels.
2x72' belt grinder made with 2' square tubing. 3/8' thick steel d-plate, the part to which the idler wheels & platen connects. d-plate tilts forwards & backward to grind bevels. the chassis are powder-coated and 8' long platen, 2' wide. 1.5 hp, single-phase, totally enclosed fan
calculating sfpm the performance of grinding wheels and quality of the finished workpiece is affected by how fast the abrasive grains sweep over the workpiece. that speed affects surface quality, workpiece burn, material removal rates, and other factors. since the speed of the abrasives on the wheel perimeter depends upon the diameter of the wheel, rpm isn't a useful measure.
the wheel speed, in terms of peripheral speed, is commonly in the range of 5,500 to 6,500 fpm (about 30 to 35 m/sec). high-speed grinding, operating at about twice that speed, is used on specially built surface grinding machines only, which are designed generally for abrasive machining and require appropriately manufactured grinding wheels.

i won't opine about the virtue of variable speed in a belt grinder, but i have very good experience with a vfd in my home shop. my single 3 hp vfd bought from a surplus dealer several decades ago is used to drive a geared-head drilling machine with integral 3-phase motor on which it would have been impossible to change to a dc motor, two lathes, a 26' bandsaw, a bench grinder, a

narrow belts are available in a wide variety of sizes and materials to fit most backstand and benchstand grinders in a range of grits for most dimensioning, intermediate grinding and polishing applications. some designs include a reversible butt splice joint so that you can use the belt in either direction for extended product life.
on a belt grinder, for example, it is the circumferential speed of the belt. on an angle grinder, it is the rotational speed of the grinding or cutting-off wheel. this is also referred to as the maximum operating speed. the cutting speed during grinding is calculated based on the following formula: vc = cutting speed [m/s] d = tool diameter [mm]
this calculator is designed to return pulley and belt information, for a given set of circumstances. the measurements are in consistent millimeters or inches, so long as they are the same throughout. in this calculator, there are three main sections dealing with pulleys, belts and speed. in each section, only one variable is calculated, based
