In a test cut on this tungsten carbide workpiece, the grinder made 35 slots 1/8" deep and 0.006" wide in 3 hours & 30 minutes! Pitch error is at 0.000080" and perpendicularity is 0.00016"
The table (X axis) is driven by a high speed linear motor which can deliver 2362ipm table speed. 

The linear motor is cooled by an oil chiller to prevent internal thermal growth.

All machine main frame components are Meehanite cast iron, PRO-E designed and FEA structure-analyzed offering optimal damping, superior rigidity and reduced deflection during high speed grinding.

 

The saddle is fixed to the large, box type all-Meehanite cast iron machine base. All linear ways on XYZ axes.

Advantages:

  • Low friction
  • Reduced machine vibration during high speed movement
  • More stability/smooth movement
  • Increased accuracy
  • Reduced cycle times
  • No stick-slip
Industry-proven grinding machine spindle technology: large diameter spindle supported by 4 ultra precision angular contact ball bearings. 

Adjustable grinding head swivel angle with ±5° adjusting range to meet various grinding applications.

Left: FANUC 18iM control with FANUC linear motor - 2.5G table acceleration; 400 times per minute table reverse & 3937ipm table speed
Right: Smart controller with PC based control and SIEMENS linear motor-1.8G table acceleration; 300 times per minute table reverse & 2362ipm table speed
  • 6" x 8" work area
  • 0.0001" X & 0.000040" YZ axis repeatability
  • 2,000-10,000rpm spindle motor
  • Slim design with small footprint
  • Conversational programming/G-code (Smart Control)
  • G-code (FANUC 18iM)

With the machine's combined speed and precision, users get accelerated cycle times,
reduced non-grinding time and increased productivity.
