Glebar offers high-precision centerless grinder

Glebar’s GT-610 CNC weighs more than 8,000 pounds and built on a mineral cast base for rigidity, vibration and thermal stability.

Glebar’s GT-610 CNC outperforms larger competing grinders, which require a much larger footprint and grinding wheels so large and heavy, a crane is required to change them. It offers high horsepower, high rigidity, and superior slide positioning. Through intelligent control and design, the G-ratios (part volume removed divided by wheel volume used) can exceed machines twice its size, all while maintaining better roundness, diameter, and taper tolerances.

The GT-610 CNC is the complete “lights-out” centerless grinding solution for applications where a high degree of automation, data gathering, and gauging feedback is required. Built on a mineral cast base for rigidity, vibration, and thermal stability, the GT-610 CNC weighs more than 8,000 pounds.

Glebar’s vast experience and unique infeed centerless grinding technology shine in this higher precision machine tool, able to process challenging components such as titanium aerospace fasteners, arthroscopic shavers, bone drill blanks, and small powdered hard metal components.

This fully automated system is capable of grinding and gauging multiple components to a high degree of precision. Configurable with pick/place gantries or 6-axis robots, this machine ensures a hands-off, high production, or frequent changeover operation with the assurance of automatic size compensation and 100 percent inspection.

The GT-610-CNC includes integrated two-axis CNC work-wheel and regulating wheel dressers capable of dressing an 8.625-inch (219mm) wide grinding wheel and a 10-inch (254mm) wide regulating wheel. Another available option is a patented programmable work rest blade, which adjusts the lateral position of the parts (when grinding).

The GT-610 CNC’s two independent slides (upper and lower), which control the regulating wheel and the work rest blade position, holding the part being ground in place, provide significantly easier and quicker set up than competing systems. The multi-axis controller can position both grinding wheel slides to a resolution of 0.1 micron (0.000004”).

The machine comes standard with a 10-inch work wheel with super precision twin grip spindle. Glebar is now offering an ABEC 7 twin-grip work wheel spindle design (with 12-inch work wheel option) on the GT-610 CNC for increased rigidity, faster component processing speed and larger diameter parts.

Glebar’s patented programmable motorized work rest blade option adjusts the lateral position of the parts (when grinding), which is ideal when controlling a radius behind a fastener head or when grinding the tip of an arthroscopic shaver, for example.

The CNC work wheel dresser incorporates 0.1 micron linear scales on both axis and a high-speed roll dress spindle, single point dressing also available. The CNC regulating wheel dresser allows for the dressing of complex shapes to achieve optimal diameter and roundness accuracy. It’s available with a variable frequency drive on the work wheel spindle for increased wheel surface feet when running super abrasives such as vitrified CBN. Spindle RPM can be varied depending on the wheel type and wheel dressing parameters.

The control software is entirely developed at Glebar and is fully customizable to address customers’ applications and processes. The intuitive touch screen interface allows for ease of use and flexibility. The machine software interface was developed to allow an unskilled operator to run many high precision machines simultaneously.

A built-in automatic wheel balancing system dynamically adjusts and eliminates wheel vibration, producing superior surface finishes and improved wheel life.

As with other high performance Glebar machines, the GT-610 CNC can be fitted with robots, pick-and-place gantries, cleaning and drying stations, laser inspection systems, and more to provide a truly hands-off turnkey solution for high production grinding applications that demand ultimate precision. OPC interfacing to supervisory plant controls is also available to gather production data and track maintenance and critical operational statistics.

This is done by using EtherCAT® by and large the fastest industrial Ethernet technology. This machine can also interface with Glebar Advanced Analytics, Glebar’s new cloud-based solution that allows operators and managers to remotely receive actionable real-time analytics on easy-to-read dashboards; reduce downtime. boost capacity, increase your availability and more.
