The Calculated Industries Machinist Calc Pro is an advanced tool for machinists, specialized engineers and manufacturing professionals. It provides precise mathematical calculations for milling, drilling, turning, grinding and more. It also serves as an electronic storage device for frequently used reference charts. The various functions and charts are great for design, layout, and minimizing wear and tear on machinery.
Basic, Dimensional Math and Trigonometry
The Machinist Calc Pro performs accurate right triangle, area and volume solutions for design, layout, or production. Use it to determine the drill bit angle for a mill so that you work at the correct angle with confidence. There are also function keys to execute trigonometry, basic math and weight calculations. All results can be entered and converted between U.S. and metric units, decimals, and fractions as low as 1/64 inch. Calculations can be entered in any of these formats or combined.
Optimized Machine Operations
Machinists can determine calculations before the work is done to optimize tool life. You can use chip load, number of teeth and rpm to determine spindle speed, cut feed and more for milling, drilling, and turning. You can also make adjustments to feed per tooth when making light-depth cuts.
Time-Saving Reference Charts
This machinist calculator has an extensive built-in drill chart. The chart is easy to understand because the drill sizes A-Z correspond to the number keys 1-26. Once you find the drill size, simply use the “+” and “-“ keys to scale up and down in size, respectively. It also has a useful list of internal and external thread sizes for screws, bolts, nuts, and more. There is a default of a 75-degree thread angle that can be changed to suit your preference. This handy reference provides sizes for cut tap drill, roll tap, close fit, free fit, cut rod, roll shank size, and all major and minor pitch diameters.
Bolt Pattern Layout Guide
As a convenient feature, the Machinist Calc Pro calculator provides a guide for the bolt pattern of a circle or wheel. Vehicle wheels vary in sizes and bolt positions or pattern. In order to securely attach the wheel, a precise pattern is required. To do this, simply enter the diameter of the circle or wheel and press the “bolt pattern” key to solve for the correct pattern or bolt spacing.
The Calculated Industries Machinist Calc Pro calculator automatically shuts off if left unused for 8-12 minutes to save battery life. There is the ability to save user preferences, plus 9 additional memory locations to store calculation results. This calculator comes complete with a bright orange Armadillo Gear hard case that is dust, shock, and water resistant, as well as 2 LR44 1.5 volt long life batteries, and a 1 year limited warranty.
