Ball screw

CNC machines require a way to transmit the power made from the actuators to drive its linear axes. The most popular linear drives used for CNC machines are: Leadscrews, ball screws, rack and pinion and belt drive. Each of these linear drive components has their own pro’s and con’s and I’ll be highlighting them, along … Read more

Stepper motor drives are the devices which convert the signals coming from the computer, and the power coming from the power supply into high power electrical signals that will power and move the stepper motors.

Cartesian Coordinate System

March 9th, 2012 | Posted by Joshua in Beginning with CNC
X, Y and Z axes

Cartesian coordinate system is used in CNC to numerically assign direction and plane of movement. A Cartesian coordinate system is made up of reference lines called a coordinate axis, or just axis. These axes are all measured in the same unit of length (for CNC it would be inches or millimeters). This coordinate system allows CNC machines … Read more
