  How To Square Up Stock     In the CNC work shop one of the first tasks a machinist must learn to do well is how to square up stock in a cnc milling machine. Squared up stock has all sides parallel to their opposite side and all angles perpendicular to adjacent sides.     Using Square stock allows you to create parts that mate well together. It is impossible to repeatedly create parts without starting from squared up stock. Since one of the reasons we use CNC milling machines is to create multiples identical parts, it only makes […]

Making A CNC Milling Machine – CNC Electronics Part 4  CNC Electronics. Making a CNC Milling machine requires you to learn a little bit about CNC electronics. Every CNC machine needs a control box with electronic components which converts electronic signals from the computer into movement. There are many different types of electronics available for CNC.  Most of the electronics fall into three basic categories; motors, control boards or power supplies. Let’s take a look at the CNC electronic components I selected to help make a CNC milling machine. Types of Motors A CNC milling machine generally  have one of […]

Making a CNC Milling Machine -Ballscrew mounts Converting a Grizzly G0704 milling machine to CNC – Part 2 Making a CNC Milling machine requires a lot of metal working. Most people will use a manual milling machine to do the metal work. I was lucky to have access to a CNC machining center so that is how I made my ballscrew mounts. A Ballscrew (sometimes spelled Ball Screw) is a type of linear actuator that translates rotary motion into linear motion. It uses ball bearing in a helical groove to transfer the motion with very little friction. The ballscrew mount […]
