New Ways To Measure Torque May Make Your Current

Really, torque is an important factor in anything that rotates or spins on a shaft, spindle or axle. A lumber mill might use a predetermined maximum torque to initiate blade changes. This saves wear on the drive system and increase product quality. This may seem like a bit of an overstatement. But if you need to measure torque and you have not

Measuring Cnc Mill Power Speed And Torque Shane Engineer

Measuring CNC mill power, speed and torque. My CNC mill is tiny. It is not very stiff, it can't spin tools very fast, and the spindle motor is a paltry 500W (~0.6HP). It's certainly fun, but these shortcomings become major limiters whenever I try to push the limits and remove a lot of material fast. My quest to probe the limits of what my mill ...
