Product Description

LEYO 450L High-precision CNC compound internal grinder

Dear customer, thank you for your interest in LEYO 450L CNC compound internal grinder, which is independently developed and produced by our company. This product adheres to the German precision manufacturing philosophy, integrates advanced CNC technology with mature process solutions, and is committed to solving the challenges of precision, efficiency, and consistency in the grinding of complex parts' internal circles and end faces.

Core advantages:

Composite machining, doubled efficiency: The original composite grinding process allows for the completion of all grinding operations for the inner circle and end face of the workpiece in a single setup. This completely eliminates positioning errors caused by multiple setups, perfectly ensuring the verticality and concentricity of the inner circle and end face, while simultaneously increasing machining efficiency by over 40%.
Extraordinary Precision, Stable and Reliable: The machine tool is crafted from high-quality Meehanite cast iron, which has undergone multiple artificial aging treatments, resulting in exceptional rigidity and strong resistance to deformation, ensuring long-term processing stability. The core components utilize high-precision ball screws and linear guide rails from German/Japanese brands, paired with high-performance CNC systems from Siemens or Fanuc, achieving micron-level (μm) processing accuracy and extremely high repeatability and positioning accuracy.
Strong power, flexibility and agility: Equipped with a high-speed electric spindle as standard, it boasts high torque, strong rigidity, and minimal vibration, easily handling precision grinding of various materials such as bearing steel, cemented carbide, ceramics, etc. The CNC system supports automatic dressing and compensation of grinding wheels, multiple grinding cycles (such as plunge and oscillatory), and flexible adjustment of process parameters, quickly adapting to the flexible production needs of multiple varieties and small batches.

FAQ

Q1: What specific costs can "composite grinding" save for me?
A: It is mainly reflected in three aspects: 1) Time cost: The inner circle and end surface machining are completed in one setup, eliminating the need for repeated setup and alignment time, resulting in an efficiency improvement of over 40%; 2) Labor cost: High automation reduces the dependence on skilled technicians, allowing one person to oversee multiple machines; 3) Quality cost: Eliminating errors caused by multiple setups significantly reduces the scrap rate and secondary rework rate.

Q2: What materials can be processed by the machine tool?
A: This machine tool is designed for processing various high-hardness metal materials, such as GCr15 bearing steel, quenched steel, alloy steel, cemented carbide, ceramics, etc. Simply select the appropriate grinding wheel and grinding parameters based on the material characteristics.

Q3: Do you offer a trial grinding service? How does it work?
A: Yes, we offer a free trial grinding service. You just need to provide the corresponding workpiece drawings and sample blanks. Our engineers will conduct on-site processing tests for you in our company showroom or through remote video, and provide a detailed processing report, allowing you to visually verify the equipment's effectiveness.

Q4: What is the delivery time for the equipment?
A: The standard delivery time for the standard model LEYO 450L is 45-60 days after the deposit is paid. If you have urgent needs or special configurations, please contact our sales manager directly, and we will do our best to coordinate to meet your schedule requirements.
