Xy axis table

Types of XY axis tables

An XY table refers to a platform that provides movement along the two perpendicular axes, the X-axis and the Y-axis. It is an essential component of CNC (Computer Numerical Control) machinery and serves various purposes in different industries.

Here's a breakdown of some common types of XY axis tables:

• Linear Slide XY Table: This machine assembly employs rails and carriages to make the motion possible. The linear slides allow for smooth movement along the X and Y axes. Thanks to that, the tables enable a positioning accuracy level that is adequate for many jobs. Such jobs may include assembly, welding, machining, and more. One popular application of linear slide XY tables is in CNC machines. That said, Linear slide XY tables are available in different types and specifications to accommodate different mini-machines and work requirements.
• Miniature XY Table: This kind of table is smaller in size compared to the standard ones. As a result, they may find their use in work devices and electronics that require very small machinery to work. A good miniature XY table example is one that fits in a medical device that people use daily. Although the actuators in this table may be bigger, some still have to be included in the device to enable its proper functioning.
• Electric-actuated XY Table: This particular assembly employs mini servos, stepper motors, and gearboxes to work. These components allow the table to move along the two axes efficiently and accurately. Electric actuated tables are usually used in automation applications where precise positioning of the workpiece is required. This makes them great for areas that need high accuracy and repeatability. Examples are electronics manufacturing, precision assembly, and quality inspection and testing. One notable feature about this XY table is that it can interface with external devices like computers and sensors. Hence, allowing for programmed and automated control of positioning tasks.
• Pneumatic XY Table: This one translates linear motion using air cylinders. Each axis of the table is actuated by a cylinder. The cylinder then gives push motion in the straight line. Pneumatic XY tables offer speedy and efficient positional changes. This works great for applications that require fast and frequent workpiece changeovers. Examples of such applications include packaging lines, material handling systems, and injection molding.

Specifications and maintenance of XY-axis tables

Specifications

• Materials: The working surface of the XY axis table is usually made of high-strength materials such as stainless steel, aluminum alloy, etc., which improves its stability and durability. Some models have a die-casting aluminum alloy base that is corrosion-resistant and lightweight for easy operation and use.
• Platform Size: The XY axis table usually consists of two flat plates, the X-axis platform, and the Y-axis platform. The size of these platforms can vary according to specific model requirements, providing sufficient space for workpieces.
• Guides: XY axis tables are often equipped with linear guides or sliding chambers. Linear rails can provide higher motion accuracy and smoothness, while sliding rails may be more economical and suitable for light-duty applications.
• Lead Screw: The XY axis table usually has a lead screw or belt system that converts the driver's motor's rotary motion into linear motion, thereby realizing the positioning and displacement of the workpiece.
• Load Capacity: The maximum load weight is specified according to the model number and is the heaviest load weight that can be supported during normal use. It is usually represented in kilograms, for example, 10 kg, and is suitable for carrying workpieces of corresponding weight.
• Drive Motor: It is usually driven by stepping motors or servo motors, which are respectively driven by a driver circuit and make the motion control more precise and programmable. The motor type will affect the motion control performance and accuracy.
• Dimensions: This specifies the overall size of the XY axis table, including length, width, and height. Dimensions may vary depending on the specific model, affecting space and adaptability in various applications.

Maintenance tips

• Clean: Wipe the work surface and guide rails of the XY axis platform using cleaning agents and wipes to prevent residual dirt or dust from affecting its movement and accuracy. Pay attention to the cleaning of the slide and track. The cleaning tools used should be appropriate to prevent damaging the slide and track surface.
• Lubrication: The guide rails and sliders should be lubricated properly to ensure smooth movement and reduce friction; lubrication should also be performed on the lead screws to reduce the skeet's wear and keep the transmission smooth. Choose the right type and amount of grease to ensure it's functioning well.
• Regular inspection: Frequently check the mechanical XY axis platform for loose connect components. Inspect the guide rails, slides, and lead screws for wear or damage, and timely replacement or repair as necessary. Also, keep fastening the parts that are often used to ensure stability and reliability.
• Dust cover or protective device: If the design has a dust cover or other protective devices, be sure to use them to avoid dust, debris, and other contaminants entering the inside of the device, thereby protecting the mechanical structure and components of the xy table.
• Storage: When not using an xy sliding table, store it in a dry and ventilated place to avoid exposure to moisture and other environmental damages. If possible, use an anti-rust spray or protective oil on the surface to protect its appearance and performance.

Scenarios in which XY axis tables work

Here are a few main applications of the worktable focusing on movement in two directions.

• Surfacings jobs: By milling, cutting or planing, an operator can easily remove material from a fixed workpiece that is clamped to an XY table slide. Surfaces on the workpieces may be either horizontal or vertical.
• Machining in two dimensions: Doing all kinds of machining jobs in just two dimensions is made easier by work tables or fixtures that allow for precise manual movements of workpieces when machinists need to carry out operations on them. Such operations may include routing, drilling, engraving, and many more that have only 2-D directions.
• Welding and assembly operations: Welding jobs requiring joining of parts positioned in arbitrary ways can greatly benefit from having their components assembled with an axis table as this device allows for easy change of the position and orientation of workpieces. This also applies to mechanical assemblies where moving elements are involved with those having sliding tables between them.
• Calibration and alignment: Devices under test need to be moved gently so that their sensors can be confirmed against known values or aligned together with certain fixed instruments at some angles which could otherwise not have been possible without using an XYZ-AXIS TABLE MACHINE. Here, the equipment's position has changed so that it can rub up against any part on the machine used, allowing for easier replacement as well as servicing. Also, alignment of electronic devices may require alignment of the electronic device under test in two dimensions with a certain fixture or sensor used to carry out the test through an axis table.
• Jigs for automated machining: Automated machining systems that need to have workpieces treated with different kinds of machine tools could use as fixtures those ones having A/JIG AXIS TABLE MACHINES OF TWO DIMENSIONS. They are equipped with a computerized control system, which allows precisely move anything included in it, featuring speed up or its accuracy, bettered by any machine tool used together with whatever is meant to be jointly machined at the same time.
• PCB (Printed Circuit Board) assembly: Precision sliding tables are multipurpose, movable platforms for electronics assembly, especially when soldering and placing Surface Mount Devices (SMDs). An XY table can help accurately position these components on a printed circuit board, guaranteeing that they will be positioned alongside excellent accuracy. This is especially true when SMD devices are being used on PCBs designed to have them.

How to Choose XY Axis Tables

  When choosing an XY axis table, it is essential to consider what one will be using the machine for and go for the ones that best suit the needs. For instance, a manual XY axis table is best for people who are on a budget or are just starting in the field but can also be used for professional work. On the other hand, an electric or digital XY axis table is more suitable for people who want precision and professionalism in their work.

• Size and Load Capacity:

  The size of an XY axis table matters as it determines the working area of the machine and the objects that can be accommodated. Among the benefits of using an XY axis table of a standard size is that it is easier to operate, find, and use the controls regardless of whether the table is digital or not. Also, the installation process is way easier than when used with a larger table. Additionally, the load capacity of the machine is something to consider, as it determines its performance and the type of object it can handle.

• Precision and Accuracy:

  One of the most important things an XY axis table has to have is precision and accuracy, as this is what the machine is mainly used for. The manufacturer usually indicates this feature in numbers, and when choosing the right table, it is important to go for the ones that provide better performance and meet the needs of a particular task.

• Material:

  When choosing an XY axis table, it is important to consider the material used to make the device, as this will determine its durability, stability, and most importantly, how much weight it can handle. All the materials used in the machine will correspond with its construction, which results in a solid and stable device that will stay in place and perform well over time.
