Linear slide cnc

Types of linear slide CNC

According to the source of power and drive mechanism used in Linear slides CNC, they can be classified into the following four types:

• Linear Slide CNC with Servo Motor

  A Linear slide CNC machine with a servo motor uses an electric motor to achieve high-precision control over the movement of its cutting components along a two-dimensional plane. Servo motors use feedback control systems that include encoders or tachometers for position and speed regulation, respectively. This type of linear slide CNC machine offers benefits such as reliable performance, high accuracy, and superior stability.

• Linear Guideway CNC Sliding Table

  The linear guideway slides work by allowing a moving component to glide smoothly along a fixed track. The design typically involves a set of roll bearings or sliding elements that provide low-friction paths for motion. Linear guideway slides offer good support capacity and allow free sliding to all directions. They provide reduced deformation shape and good moveability.

• T-Liner Slide CNC Machine

  A T-type linear slide CNC machine comprises two major parts. The first is the T-profile that slides and mounts perpendicular to the work surface as the moving component, while the second involves any cutting tool that performs tasks such as engraving or milling. Despite their simplicity, T-liner slides offer a relatively accurate solution for low-cost CNC machines.

• Pulley Linear Slide CNC

  A pulley linear slide CNC system uses a set of pulleys to attain movement by guiding the path of a cable or belt attached to the workpiece. One of the major advantages of pulley slides in CNC systems is their ability to provide a lightweight yet durable motion-transmission mechanism. This feature makes it compatible with different applications, including 3D printers and laser cutters.

Specification and maintenance of linear slide CNC

Specification

• Size: Linear slides come in different lengths, heights, and widths, with a typical length of around 220-270mm. The size should be determined based on the device it will be used with and the work needs.
• Load capacity: Load capacity depends on the material and manufacturing. For example, aluminum alloy linear slides have a typical load capacity starts from 1.5 kg, while steel slides can hold a more than 25 kg weight. The load capacity must be chosen according to the device's weight and requirements to ensure linear slides support the required weight.
• Guideway type: Linear slides usually have two guideway types: roller guides and belt guides. Roller guides use rollers to support and move, providing quick and smooth sliding, for which they are widely used in the areas of precision machinery and automation equipment. On the other hand, belt guides utilize a belt to convey objects, which is ideally suited for high-speed and long-distance transmissions, as commonly seen in conveyor systems and material handling. The guideway types should be chosen based on the device's needs and working conditions.
• Lubrication: Some linear slides come pre-lubed, while others need lube before installation. Standard lubricants include grease or oil that lower friction and wear between sliding surfaces.
• Material: Linear slides are typically made of aluminum alloy and stainless steel. Slides made of aluminum are lightweight and rustproof and are applied to devices that don't need heavy loads. Stainless steel slides are strong and durable in harsh scenarios.

Maintenance

• Cleaning: Schedule regular cleaning to get dirt, chips, and debris off the slide by using a lint-free cloth or a soft brush. Make sure the slide lasts a long time by keeping it clean and tidy.
• Lubrication: Apply a small characteristic or slide grease/oil to the lubricant to lower friction and wear. If possible, regularly lubricate the slide with slides-specific grease/oil. Oiling/lubing intervals and the amount of lube needed should refer to the manufacturer's guidelines.
• Adjust: If the linear guide slide shows signs of looseness or difficulty in sliding, the adjustment may be required. Please check the looseness of the fixed parts of the slide and adjust them accordingly to ensure the proper position and stability of the slide.
• Inspection: Frequently inspect the linear slide for damage such as bending, cracking, or excessive wear. Make prompt replacement if some parts are damaged to avoid affecting device performance.
• Environmental control: Control the environment the slide is in by keeping it away from humidity, high-temperature, and corrosive materials to avoid aging and damage to the slide. If the working environment is harsh, the slide needs more frequent maintenance and attention to ensure it works properly.
