How to Square Up Stock in a CNC Milling Machine
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 – Increasing the travel
Making a CNC Milling Machine – Increasing the travel Part 3 I have been working on making a CNC milling machine from a Grizzly G0704 manual milling machine. Welcome back to my blog. I have looked at several modifications to the Grizzly G0704 and one that seem really useful is increasing the travel on the Y and Z axis. Increasing the travel will require some pretty serious modifications to the existing castings and will definitely void your warranty. Increasing the travel of the Y axis will require that I
Making a CNC Milling Machine -Ballscrew mounts
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 […]
Make A CNC Milling Machine
Make A CNC Milling Machine I recently decided that I wanted a CNC Milling Machine to add to my workshop. A CNC Milling machine will allow me to do my prototype work in my workshop instead of using a service. Now CNC Milling Machines are not cheap. they can cost tens of thousands of dollars. I am not made of money so I guess a $50,000 CNC Milling Machine is out of the question. But what if I #Make a CNC Milling Machine instead? Could I keep the cost down to a level that won’t break the bank? Can I […]
