Brief Description About CNC Rotary Surface Grinder

  • PINNACLE is one of the superior companies in manufacturing rotary surface grinders. CNC Rotary Surface Grinder manufacturers are designed to use the full potential of rotary surface grinding, which has numerous advantages over rotary table grinding.

  • A CNC rotary machine is an automatically controlled grinding machine. This machine is responsible for the final surface treatment of finished metal products and the removal of material from the workpiece with grinding wheels.

  • The Pinnacle PHR series CNC machines are CNC-Controlled high-precision surface grinding machines with rotary tables and horizontal spindles, based on the latest European column motion concept.

  • A hydrodynamic table is provided that is designed to carry heavy loads on the rotating axis, i.e., on the B-Axis, ignoring structural wear and impurities due to rotational oscillations.

  • Vertical Axis, i.e., the Air-Axis, is driven by an AC servo motor via ball screws and double precision nuts.

  • Cross (Traverse) Axis: The Z-Axis drives AC. The servo motor screws it through precision ball screws and double nuts.

  • The grinding spindle cartridge is equipped with durable imported SUPER PRECISION BEARINGS and fully imported grease for long, trouble-free operation.

  • The PHR CNC Rotary Surface Grinder manufacturers are mainly used for high efficiency/mass production purposes, significantly reducing operator dependence.

  • The PHR NC series machines are used in a variety of applications such as tool shop grinding, woodworking machine parts, diamond industry, gear manufacturing, automotive industry, and bearing and pump industries.
