LJ-3740CA
CNC Precision Cam Grinder
The LJ-CA series features a Siemens 840D controller for precise dual-axis synchronized grinding.
Wide Applications–Supporting up to 35mm eccentricity for cams, eccentric shafts, CAPTO, and more.
Features
Dual-axis height matching
Wheelhead Moving Axial (X Axial) and Work Spindle Axial (C Axial) synchronized grinding with dual-axis height matching.
Linear Motor Driveing
The grinding wheel movement axial (X Axial) utilizes a linear motor for high dynamic response, minimizing backlash and enhancing precision.
Actual Measurement Accuracy Report
Extracted from customer machine accuracy report Dual-stage eccentric roundness within 3µm Dual-stage eccentric phase angle error within 5'
Dual-axis height-matched grinding significantly enhances machining efficiency.
Extracted from the customer's grinding work order: Three-stage grinding completed in 5 minutes. Form reproduced by Lih Jaan.
Infinite segment grinding within the workpiece length.
FC30 Meehanite base, ensures precision, stability, and durability.
