Calculators for machinists, mechanics and foundry workers
Spindle speed, tap drill, metal weight, bending force, hoist and sling selection, press lining wear, sand permeability. Any result can be sent to a MELITA engineer for review.
Metalworking
Spindle speed and feedEnter the drill or workpiece diameter, material and tool type - the calculator returns spindle speed, feed per revolution, feed rate and whether to use coolant.Calculate →Drill press selectorEnter the largest hole you drill in steel and the part height - the calculator suggests the machine type, spindle taper, motor power and supply voltage.Calculate →Tap drill sizePick the thread and pitch - the calculator gives the drill size for cutting and forming taps, the minimum blind hole depth and the thread profile depth.Calculate →Band saw tooth pitchEnter what you cut - solid bar, tube or profile, its size and material. The calculator returns the tooth pitch in TPI and the band speed in m/min.Calculate →Metal weight calculatorPick the profile, material and dimensions - the calculator gives the part weight in kilograms so you can choose a magnetic lifter, hoist or slings.Calculate →
Sheet metal
Bending and punching forceEnter thickness, bend length and material - the calculator gives the V-die opening, bending force in tonnes, minimum flange, and the punching force for a given hole diameter.Calculate →Flat pattern and bend radiusEnter the outside flange dimensions, thickness, inside radius and bend angle - the calculator returns the blank length before bending and the bend allowance.Calculate →
Lifting equipment
Electric hoist selectorEnter the load weight, lifting height and how often the hoist works - the calculator picks a capacity from the standard range, an I-beam size and an approximate rope length.Calculate →Hoist parts by nameplateEnter the motor type from the hoist nameplate - the calculator shows the capacity and which brake lining, coupling, fan and rotor fit that motor.Calculate →Sling loadEnter the load weight, number of legs and angle from vertical - the calculator gives the force in each leg and the minimum working load limit per leg.Calculate →
Presses and foundry
Clutch-brake lining wearEnter the new lining thickness, current thickness, the minimum from the press passport and wear per month - the calculator shows remaining life in percent and months to replacement.Calculate →Sand permeability and moistureEnter the pressure and air flow time through the specimen and the sample mass before and after drying - the calculator returns sand permeability and moisture and compares them with typical values.Calculate →
