CNC System

Configured CNC System: FAGOR 8070

CNC Axes

• X axis: Transverse feed motion of the grinding wheel frame with full closed-loop control via grating ruler.
• B axis: Workpiece spindle rotary motion with full closed-loop control using angle encoder.
• C axis: Rotary table motion with full closed-loop angle encoder control (optional).
• Y axis: Longitudinal reciprocating motion of the grinding wheel frame.
• W axis: Automatic cleaning feed motion of the grinding wheel (optional).

(X, B, C are linkage axes; W axis optional.)

Application & Capabilities

The machine is mainly used for grinding triangle, square, long diamond, polygon, and round indexable inserts. It is designed for high-precision machining of hard alloy, ceramic, and CBN indexable inserts. The imported FAGOR 8070 CNC system combined with an articulated manipulator allows one-time clamping for:

• Peripheral contour machining
• Chamfering (single or double-sided)
• Rounding
• Non-standard blade curve machining

Highly suitable for mass production.

Performance Accuracy

Working dimensional accuracy	±0.012 mm
Profile error	0.01 mm
Cutting angle error	±10′
Surface roughness	Ra 0.4

 

Key Features

• The machine tool supports five-axis, three-linkage control.
• One clamping allows double-sided chamfering of the insert.
• Automatic measurement of workpiece shape and thickness.
• Optional automatic grinding wheel cleaning device.
• Articulated manipulator for automatic loading/unloading.
• Grinding wheel spindle driven externally and balanced to minimize thermal deformation.
• Hydraulic automatic clamping of workpieces, with adjustable clamping force.
• User-friendly human–machine interface for simple programming and editing.
• Fully enclosed protective system with efficient oil-mist extraction device.
