Product Description

FX Series High-Precision CNC Centerless Grinding Machines

Standard 1–60 mm / Custom 40–120 mm large-format high-end CNC centerless grinders, equipped with a Siemens 828D CNC system and multi-axis servo interpolation, supporting both continuous and plunge grinding modes.
 
These machines achieve micron-level precision control of 0.001 mm and are suitable for the automated, large-scale, ultra-precision grinding of large-format shafts, rings, and tapered/curved irregular parts in industries such as bearings, heavy-duty automotive components, construction machinery, and precision molds. It is designed for the automated, large-scale, ultra-precision grinding of large-diameter shafts, rings, tapered surfaces, and curved irregular parts, balancing the high rigidity required for large-diameter machining with the high precision of CNC technology. This machine serves as the core equipment for high-end grinding of medium-to-large precision parts.

Core Product Advantages

1. Standard + Customized Solutions Covering All Sizes of Medium to Large Parts
Standard machining diameters range from 1 to 60 mm, with customizable extensions up to 40 to 120 mm. This accommodates grinding requirements for everything from small to medium-sized precision parts to large, heavy-duty shafts and rings, addressing the cost challenges associated with using multiple machines for multi-specification processing. It serves core industrial sectors such as heavy-duty automotive parts, construction machinery, large bearings, and precision hardware.

2. Dual Grinding Modes + Form Grinding
Continuous Grinding: Designed for batch grinding of large-sized standard shafts and rings with cylindrical surfaces. The precise rough grinding (0.03–0.05 mm) + fine grinding (0.01–0.015 mm) process is ideal for large-scale production line operations;

Plunge Grinding + Profile Grinding: Utilizing two-axis servo-linked grinding wheel dressing to achieve precision profile grinding of irregular medium-to-large rotating surfaces such as conical and curved surfaces, meeting the high-end custom machining demands for non-standard irregular parts. A single machine achieves both "batch grinding of standard parts" and "profile grinding of irregular parts."

3. Fully CNC Servo-Linked System
Equipped with a Siemens 828D CNC system and multiple servo motors, the system achieves a minimum servo feed accuracy of 0.001 mm and spindle runout ≤ 0.001 mm, ensuring precise execution and consistency in batch processing.

4. Upgradeable to a Fully Automated Production Line
Equipped with standard CNC core components, the machine offers an optional gantry-type automatic loading/unloading system (with customizable grippers). When paired with front-end automatic feeding and rear-end conveyor belt unloading, it achieves full-process automation from workpiece loading, positioning, and grinding to unloading, addressing the issues of low efficiency and high labor intensity associated with manual handling of large-sized parts.

5. Fully Automatic Two-Axis Sanding
Equipped with a cross-structure two-axis servo automatic sanding system, it utilizes the CNC system to perform two-axis interpolated sanding, resulting in higher precision and more uniform sanding.

Solving Industry Pain Points

♦ Addressing machine body deformation during the grinding of large-sized parts: 

The FC-30 features a cast iron body combined with heat treatment and natural aging, resulting in a highly rigid structure that resists deformation and vibration, making it suitable for high-load grinding operations.

♦ Overcoming limitations in the processing range for large-sized parts: 

The standard range is 1–60 mm, but it can be customized to extend up to 120 mm, allowing a single machine to handle the grinding of all sizes of medium to large parts.

♦ Solves precision deviation issues in large-part grinding:

 0.001 mm micron-level feed + spindle runout ≤ 0.001 mm; CNC precision control ensures zero dimensional deviation

♦ Solves the difficulty of contour grinding for large, irregularly shaped parts: 

Two-axis servo-linked grinding wheel dressing and interpolation contouring enable precise grinding of conical surfaces, arcs, and other irregular rotary surfaces

♦ Solves the problem of low efficiency in manual loading/unloading of large parts: 

Optional gantry-type automatic loading/unloading system enables full-process automation, reducing labor intensity and improving efficiency

♦ Solves the problem of high transmission losses in older grinding machines: 

Delta servo synchronous belt direct drive eliminates chain inertia losses and angular deviations, ensuring uncompromised grinding accuracy

♦ Solves slow setup times for processing multiple part varieties: 

Siemens 828D system stores grinding parameters for one-click switching, significantly reducing changeover time

♦  Solves the issue of low surface finish on large-sized parts:

 Continuous grinding achieves a surface roughness of Ra 0.1 μm, far exceeding industry standards and meeting the surface finish requirements of high-end manufacturing
