In the ever-evolving landscape of precision manufacturing, CNC (Computer Numerical Control) machine tools have become indispensable workhorses, enabling high-speed, accurate, and consistent production across various industries. At the heart of these sophisticated machines lies a critical component – the rotary table bearing – which plays a pivotal role in ensuring smooth and precise rotational movements, essential for achieving exceptional machining accuracy and efficiency.

Understanding CNC Machine Tools

CNC machine tools are automated manufacturing systems that utilize computer-controlled cutting tools to shape, drill, or mill a wide range of materials, including metals, plastics, and composites. These versatile machines are extensively used in industries such as aerospace, automotive, medical, and consumer product manufacturing, where precision and repeatability are paramount.

CNC machine tools are designed to operate with high levels of accuracy, speed, and consistency, enabling complex shapes and intricate details to be machined with exceptional precision. These machines are equipped with advanced control systems, robust structures, and specialized components to meet the demanding requirements of modern manufacturing processes.

The Importance of Rotary Table Bearings in CNC Machine Tools

Rotary table bearings are essential components in CNC machine tool design, enabling the precise and controlled rotational movements required for accurate machining operations. These specialized bearings are engineered to withstand the extreme conditions and heavy loads encountered in high-speed machining environments, while providing superior precision and rigidity.

The selection of the appropriate rotary table bearing is crucial for the efficient and accurate operation of CNC machine tools. Key factors to consider include:

  1. Load Capacity: Rotary table bearings must be capable of supporting the combined radial and axial loads imposed by the workpiece, cutting forces, and operational forces encountered during machining operations.
  2. Precision and Rigidity: High levels of precision and rigidity are essential for rotary table bearings to ensure accurate positioning and minimal deflection during machining processes, contributing to the overall dimensional accuracy of the finished parts.
  3. High-Speed Capability: Many CNC machine tool applications involve high-speed machining operations, requiring rotary table bearings that can withstand high rotational speeds while maintaining smooth and consistent performance.
  4. Durability and Wear Resistance: The harsh operating conditions in CNC machining environments, such as exposure to coolants, chips, and abrasive particles, necessitate the use of durable and wear-resistant rotary table bearings to extend service life and minimize downtime.
  5. Customization and Design Flexibility: The diverse range of CNC machine tool applications often requires customized rotary table bearing solutions tailored to specific design constraints and performance criteria.

In August 2020, LKPB successfully partnered with a UK** company on a CNC Machine Tools project.

Before the customer used INA rotary table bearings, bearing price is high, long delivery time, after the introduction and comparison of my company’s technical staff, LKPB bearings in all aspects are very advantageous, but the customer is worried about the quality of our bearings and INA bearings have a gap, hesitate to make a decision, after three months of uninterrupted sample testing, the customer has a better understanding of the company’s products, the results of the test are no problem, and the INA bearings performance parameters are consistent, LKPB bearings good quality and low price won the customer’s recognition, the subsequent establishment of a long-term relationship with the customer. The performance parameters of LKPB bearings are the same, LKPB bearings have been recognized by customers for their good quality and low price, and we have established a long-term cooperative relationship with them.
Our products are mainly used in the customer’s horizontal machining center machine tool rotary table, the use of the bearing type YRT260, YRT325, YRT395 and YRT580, the accuracy of P2 grade.
