The horizontal motion provided by X-Y tables is ideal for automated machinery. This is especially true in the case of assembly robots within different respective facilities. The reason for this is that automated machinery, like robotic arms, have bases that are stationary and only are able to move in certain directions. X-Y tables are able to make the basis of these machine types capable of moving in directions horizontally along an X and Y axis. These tables are also referred to as X-Y stages or positioning tables. X-Y tables are motorized and have linear slides. Linear slides can serve a variety of useful applications in different configurations of X-Y tables. X-Y tables also utilize a linear motor. The necessary motion comes from bearings operated by drive mechanical components. In most cases, these kinds of tables are driven entirely by a linear motor. X-Y tables are commonly designed to provide positioning along an axis.

Common Applications of XY Tables
X-Y and positioning tables have multiple useful applications in many different industries. Some of these industries include general machinery industries, the pharmaceutical industry, manufacturing industries, the semiconductor industry, and any other industries that require automated movement in their construction processes. X-Y tables are also commonly used in multiple mechanical processes. Some of these processes include material handling, industrial automation, the building of machinery, and multiple different automated measurement processes. These tables are important in these industries because of their ability to precisely direct movement in a way that other tools simply are unable to.
Positioning Stages and Their Uses
Positioning stages are a type of rotary positioning table commonly used for scientific or industrial purposes. Positioning tables are equipped with gibs on each respective axis. They can provide high-speed positioning of light payloads and are constructed in a few different ways. Their construction and design depend on what they will be used for and which type of linear motor will be attached to them. Many roller tables are designed to have low profiles and are also equipped with crossed rollerways. Roller tables have a wide variety of uses.
Most X-Y tables consist of a flat surface mounted on some sort of ball bearing slide or roller slide. They have multiple bases that are made up of platens, a flat platform, and forcers. The forcers are designed to glide over the platen utilizing air bearings, also known as aerostatical bearings. Air bearings utilize a thin layer of pressurized air in order to create a no-friction environment. The forcer moves in a constant linear motion over the top of the platen. In order for multiple axis to be created, the linear bases are stacked on top of each other. The "Y" axis acts as a carriage at the base and acts as the base that is holding the table. Adjustable gibs can also be added onto the sides of either axis. Gibs are typically added to tables in the robotics industry to aid in robotic movement. When used this way, they are referred to as positioning tables.
What to Keep in Mind when Purchasing an XY Table
When looking to purchase positioning tables, consumers should choose high-precision designs. They should also take into consideration which type of positioning technology their tables will be equipped with. Tables can be optimized for different applications and can come in many custom variations. Choosing the right table can help significantly reduce design workload. Many are lightweight and have a high level of rigidity. This is achieved through optimal cross-section design. Choosing a table with an aluminum alloy type base will make it more compact and lightweight. A well-constructed ball screw circulation system is another useful feature which will reduce friction and noise. Be sure to choose a table constructed of premium materials, good ball screws, strong support units, and linear guides. It will last longer and be easier to use.
Design Features To Consider
These days, there are a wide variety of tables available to consumers. X-Y tables can be custom made or chosen from a wide range of pre-constructed designs. Some of them have very innovative design features that can assist in the bettering of the construction processes within many industries.
Improvements and Add Ons
Lots of tables boast improved efficiency in their designs and utilize modular systems for their drive axis. Many have helpful linear guides which assist with the straightening of motion. Others leave availability for multi-axis combinations. Newer designs include built-in sensor units. A few models will come with top and side covers as well.
High Precision Positioning
Many tables have options available for high-precision positioning. There are multiple sizes to choose from which optimise position exactitude. Using a Z-axis can be helpful for saving space and reduce cross-section height while helping with precision movements. Tables with precision bearings provide both high accuracy and high rigidity alignment. If they have a high precision linear optical scale, they will have higher resolutions. There are also different types of high precision worm gear driven rotary tables, which can be put to a variety of useful applications.
Tables With Smooth and Controlled Motion
When tables have equal inertia between the upper and lower axis, they tend to have excellent controllability. A few can be designed with an open frame that has the ball screws on the exterior. If they incorporate a roller and retainer, they will have a very smooth motion. Designs that feature a slim alignment will allow better X, Y and O motions. Some kinds of tables even feature multiple sliders that can be placed on a single axis and independently driven.
Custom Designs and a Wide Range of Options
Many tables are designed for general industrial use, but custom ones can be constructed for special purposes. Most are available with some kind of warranty. A curved rail design is another common feature. This curved rail design is useful in transporting light payloads. Some systems are food grade compliant which is necessary for the food and beverage industry. Food compliant tables are almost always extremely resistant to corrosion. There are so many innovative designs emerging within the robotics industry. It makes sense that X-Y tables are also improving and experiencing useful feature upgrades on a regular basis.
It can be very helpful for consumers to know what options are available to them when they are making a purchasing decision.
