Ballscrew CNC vs. Rack & Pinon

Sometimes a home repair project is a small repair that might be better to leave to a professional. However, there are some things that you can do yourself. For example, if only one screw needs to be tightened or a small part needs replacing, then you can probably handle that at home.

The big question is whether it should be done with a BallScrew CNC or a Rack & Pinion? In this article, we’ll see the difference between the two and which one would be best for your home.

Removing a Screw with BallScrew CNC or Rack & Pinion?

Removing a screw with a ball screw is a lot easier than a rack & pinion. All you have to do is get the right size socket and turn it to remove that stubborn screw. You can read more about that process in our previous article here.

Historically, less costly CNC routers were driven by a Rack and Pinion mechanism while high-priced aerospace and metalworking mills were driven by Ball Screws. With these advancements in mind, Ball Screw systems are now used across the industry to make CNC Routers more accurate and reliable. Ball Screws are machined and offer lower friction and higher accuracy.

When selecting a CNC system, you must consider the quality of the drive system. KG International’s ballscrew CNC systems use Ball Screws which are more reliable than Rack and Pinion. The three reasons for choosing Ball Screw are as follows.

Reduce Wear and Tear

Wear and tear levels are improved with ball screw systems. Our ballscrew CNC router tables have ball screws with a sealed bearing and many re-circulating ball bearings evenly spaced and constantly lubricated as it moves through a channel design. It is crucial to clear the channel before starting the engine, or it can cause damage to the inner bearing.

Rack and Pinion do not have the technology that KG International does, since KG International has a gear-and-track system with lubrication. (metal-on-metal contact). You should regularly apply oil to the track. When you cut it, dirt and damage will result even if lubrication is present. This increases the wear and decreases its lubrication.

Over time, you’ll experience backlash if the gears aren’t aligned correctly. Sticking occurs when the Rack and Pinion are forced to stop repeatedly on the same points.

Our ball screw design has an increased number of contact points between the bearings and the nut, which minimizes wear on the system. The result is that our ball screws can hold accuracy longer.

Improved Overall Accuracy

Ball Screws are more accurate as they have less backlash than a Rack and Pinion mechanism. The linear motion offered by Rack and Pinions is not as repeatable as it seems because the gears tend to wear out. Ball Bearings are not made to the same precision as Rack and Pinion systems. Ball screws are frequently used to create precision movement, as it is crucial for any industrial CNC machine. They trust best-in-class technology when precision and tolerance is of the utmost importance.

Re-circulating ball bearings are used on all Linear Guide Rail systems and are a trusted technology. Your company needs to update your aging equipment and replace it with cutting-edge technology like this.

Ball screw technology makes the X Y-Axis much smoother than other motion systems. Using a Rack and Pinion system on your XY axis will allow for uneven wear as two unique gears spin independently of one another.

Don’t expect to always work in the middle of your table. Work can sometimes be done on one side or another, or at the front or back of the machine, which will wear out parts unevenly, creating an uneven wear pattern. Eventually, use of your machine will cause one gear to become smaller than the other, causing a wobble or inefficiency in your work.

Cut forces and machine movements

One of the most important considerations is overall cut forces and machine movements. Ball screw drives give you maximum cut force and speed. Rack and Pinion will not keep the gantry straight because it is applying uneven forces to both gears. The gantry needs even force across the teeth in order for the rack and pinion system to work correctly. There will be a chance of missing steps, gear fracturing, or pinion stress.

Competitors without intelligent control systems are likely to end up slowing you down or scrapping parts that don’t turn outright. Rack and pinion designs demand precise synchronization between both sides, so any delay in motor reaction will throw your cuts off. KG International’s ballscrew CNC machines feature high-resolution, low-cut forces and outstanding quality components.

This means they have no difficulty accomplishing this goal. We are so confident in it that we even had a full-grown man try to tear our table apart with his bare hands. The machine is built with parts bigger than anything else on the market, which makes accuracy no problem for KG International’s CNC.
