CNC belt grinding and satin-finishing machines

Compact machine consisting of an abrasive band unit and a 2-position indexed rotating table for belt grinding or satin finishing flat or concave workpieces. Workpieces can be loaded/unloaded in concurrent time during the operating cycle. This machine is available in 3 different configurations for 3 different working modes: MicroB MicroB-CNC MicroB-S

  • Satin-finishing
  • Emery polishing

Emerising (removing material)

Before emerising

After emerising

Characteristics

  • MicroB: material removal by absolute dimension control of apply force of the controlled pad
  • MicroB-CNC: control of material removal or absolute dimension through a numerical axis
  • MicroB-S: Decorative finish "lengthwise satin finishing" or "straight graining"
  • Dry or sprayed working
  • Height measurement function of the workpiece before machining
  • Workpieces loaded and unloaded in masked time
  • Flexible and compact, meeting requirements of regularity, even for small series

Specificities

  • Fanuc numerical control with BULA graphic interface
  • Belt oscillation amplitude can be adjusted
  • Automatic tool wear management for optimum work regularity
  • Work zone that facilitates retrieval of machining residues
3 configurations available:

microB Range: CNC Belt Grinding and Satin-Finishing Machines

The microB range comprises compact machines designed for belt grinding and satin-finishing for flat or concave workpieces. Each machine features an abrasive belt unit and a 2-position indexed rotating table, allowing for simultaneous loading and unloading of workpieces during the operating cycle. The range offers three distinct configurations to suit different working modes: microB, microB-CNC, and microB-S.

Characteristics and Configurations

  • microB: Achieves material removal through absolute dimension control of the controlled pad's applied force.
  • microB-CNC: Provides material removal or absolute dimension control via a numerical axis, offering precise control.
  • microB-S: Specializes in decorative finishes like "lengthwise satin finishing" or "straight graining."

All models support dry or sprayed working and feature a height measurement function for the workpiece before machining. They are designed for flexible and compact operation, meeting regularity requirements even for small series, with workpieces loaded and unloaded in masked time.

Specificities

The microB range is equipped with a Fanuc numerical control system featuring a BULA graphic interface. 

Key specificities include:

  • Adjustable belt oscillation amplitude.
  • Automatic tool wear management for optimal work regularity.
  • A work zone designed to facilitate the retrieval of machining residues.
