### Question #: 14104

Question: What are the mounting hole dimensions of the 1/2" Anti-Backlash Lead Nut

Current Solution

The mounting hole dimension for the 1/2" 10 TPI 5 starts antibacklash nut is 1.13" or 28.7 mm. I added a drawing to the antibacklash nut product webpage so you can see other dimensions.

Thanks

• WHAT ARE THE DIMENSIONS FOR GREENBULL TABLE?

Actual table dimension: 4'x8' is 56.078"x 121.50" (the overhang in the illustrations should be 3/4" thick)
To determine the frame dimensions, first consider using the frame height shown of almost 3' (2.86'). The width of the frame should be 4" narrower than the dimension from rail edge to rail edge (6X rail to rail is 80.078"). This will provide a 2" overhang on both sides (4X frame width should be 56.078").
The length of the frame should be 4" shorter than the desired length of the rails to provide a 2" overhang on both ends. The travel length will be 20" shorter than the rail length due to the space occupied by the gantry sides.
Two long pieces of 3/4" material will need to be placed on top of the frame with the 2" overhang on the sides and the end. These long strips of material will receive the rails and the chain mounts on the ends.

• HI, I HAVE INTENTION OF PURCHASING YOUR 1/2 INCH PRECISION LEAD SCREW SET TO BUILD MY CNC MACHINE, COULD THE SCHEMATIC DIMENSION ANTI-BACKLASH NUT, BEARING FOR AND SHIM? ALSO IS 2.2KW SPINDLE ABLE MILL ALUMINUM WHAT ACCURACY?

BYCNC response:

Milling aluminum is no problem with our machines.

Here is a video we recently did with our 4'x8' machine. The aluminum piece is about 1/4" thick: https://buildyourcnc.com/tutorials/tutorial-greenbull-aluminum-cutting

The accuracy you will see from our our 2.2kW spindle is entirely dependent on the precision of your build, so it's not possible to say what level of accuracy you can achieve without an examination of the complete system. However, our spindles have a runout of less than .0001 in, which includes the collets that we sell. If you use a collet from another manufacturer, we cannot guarantee this TIR (Total Indicated Runout) dimension.

• If I order 19ft of the 1/2" lead screw will it come in three 6'5" lengths by default? This is what I need. Thanks

No they will not come in that length as a default, we would contact the buyer to ask specific lengths due to the total length purchased.

However if you order the 1/2" lead screw we can get them cut to the specific length you require, by contacting us here or call us at 281-815-7701.

• I just changed my X and Y to the ACME 1/2" 5 start lead screw. What are the motor tuning numbers. I have the book built machine.

The settings that will have to be change will be your steps per inch in motor tuning (mach 3), or settings/axes(planetCNC). But we do not have the actual numbers/specs that will fit your 10 TPI 5 start lead screw, here is a tutorial video which explains how to get the exact numbers you need! (

• WHAT ARE THE HEALTH RISKS OF LIVING NEAR A CELL PHONE TOWER?

There is very little radiofrequency (RF) energy exposure to people inside a building from a cellular base station located on its roof. There are several reasons for this. First, the transmitters operate at low power levels. Second, the antennas are normally mounted near the edges of the roof and are aimed away from the building. Third, most cellular transmitters use "high gain" or panel antennas. Such antennas transmit most of their energy in a narrow beam (in the vertical direction) from their front surfaces, away from the building. They radiate very little energy downwards towards the roof or backwards from their rear surfaces. Finally, building materials absorb a significant fraction of the RF energy passing through them. As a result, the RF signal levels at any location inside the building are invariably low and far below safety limits. The situation might be different in some locations on the roof itself. RF signal levels close to (within a few feet) and directly in front of cellular base station antennas can easily exceed safety limits. Some precautions are needed to prevent people from walking directly in front of the antennas while they are transmitting. This applies also to paging and other systems that use rooftop antennas, some of which transmit at higher power levels than many cellular base stations. Kenneth R. Foster, Ph.D.

• when buying 1.5m of 1/2" Lead Screw per inch (Steel) does it ship as a whole rod or do i need to specify what lengths i need?

When buying any of our ACME screws, if the entire length or lengths is desired please send us an email or a call, to specify the actual length needed! But if no call or email is sent previous of the order then, we will give the customer a call or email to find the exact lengths that they will require.
