These machines easily handle large sheets, Cnc Router Machine 4x4 Windows or can machine small parts by the thousand. Recently Updated Fouter Your Gantry.

With decades of experience in the design and fabrication of tooling and material handling equipment for the automotive industry as well as specific expertise in the development of computer-controlled machinery, our vast knowledge base and attention to detail is second to none. At Romaxx, our aim is to create the most reliable and precise CNC Router equipment available today, at prices that simply cannot be beaten. Skip to content. Learn More. Romaxx is now offering an extensive list of options available on every CNC machine we manufacture.

From a bare bones machine to a fully featured power house, Romaxx has you covered! You want to decrease Moment B as much as possible. You want to make have equal amounts of force on your set of linear bearings as possible. This will reduce deformation and chatter in your machine. A well designed machine keeps force Cnc Router Machine For Sale Philippines For C and force D to be as equal as possible. And that is the goal. Force C and D are the Best Cnc Router For Wood Signs Code sum of the weight of the machine and resulting forces that occur do to moment B.

The center of gravity is the point at which the machine would balance. That is why you often see the gantry upright side arms slanted backwards an a do it yourself CNC router. This compensated for the weight of the spindle which hangs our over the Y-axis linear bearings. When you build a do it yourself CNC router, you want the center of gravity of the whole gantry assembly to be directly between the two linear bearings.

Or if you have a stationary gantry and a mobile bed, you want center of gravity to be in the center of the bottom of you gantry side arms.

This assures that your machine is balanced and could stand own its own. This applies equal load on your bearings. Minimize D2. Keep the spindle plunge arm on the Z-axis assembly as short as possible and make that arm out of rigid material to prevent flexing. A normal Z-axis arm travel is anywhere from 3 to 6 inches. Minimize D1. Calculate or estimate where the center of gravity of the gantry will be located, including the spindle.

Design your gantry side arms to compensate and place the center of gravity CG between the front and back X-axis linear bearings per arm. Maximize D3. A good gantry design is one of the most crucial factors for a quality do it yourself CNC router. Try and visualize and estimate the forces evolved and make your do it yourself CNC router design work with the materials you have.

If you would like a more thorough analysis you may consult us. We offer free engineering design analysis of your machine. We can help you find:. Specific CG location Material stress and strain analysis Dynamic simulation of your machine Material selection And more.

Remember, we will discuss more on the gantry design in later section. Topics such as lead screw placement, motor placement, linear bearing attachments, etc. Which are all important consideration with a do it yourself CNC router project.
