The Glebar Advantage

Redesigned from the ground up, the CAM.2 represents a completely new paradigm in micro-grinding and guidewire grinding. Unlike other designs, there are no sensors or sensing systems to move, and the accuracy is not dependent on wire cut length. Competitors try to replicate our results to no avail by affixing additional systems onto decades-old designs.

At the heart of the CAM.2 lies our continuous feed system, which allows virtually unlimited part length. Consisting of a pair of direct drive linear motors, their exacting motion is synchronized by an advanced controller, incurring no loss of precision during part handling. Competing designs must stop, reset, and re-clamp the part, causing them to be inefficient, lose length accuracy, and introduce the possibility of defects such as undercuts at re-clamping points. Our pair of linear motors is checked by laser interferometer to ensure sub-micron accuracy, allowing the machine to deliver performance others can only claim.

Introducing the CAM.2

  • The CAM.2 represents the ultimate in medical guidewire grinding, capable of holding the tightest tolerances in the industry.
  • In the exciting field of micro-grinding, the capability of the CAM.2 to produce flats, radiuses, needle points, and non-linear shapes makes this the perfect machine to grind complex medical guidewires, dental parts, and small precision parts for various industries. Combining the latest in multi-axis servo motor control, submicron positioning, and an intuitive 15" HMI, the CAM.2 offers unmatched performance.
  • With the CAM.2's full-fledged G-code underpinnings, direct integration with CAD/CAM packages is seamless. Previously unproduceable parts can be made easily, with minimal setup time, and with limited operator training. Glebar's ability to customize all aspects of our system, going beyond material handling to incorporate features that were previously separate operations, have saved customers time, floor space, and production costs.

CAM.2 Highlights

Granite Machine Bed

Granite Machine Bed

The CAM.2 is built on a 2,200 pound 6" (152mm) thick granite bed, for enhanced rigidity, thermal and vibratory stability.

 

Patented Feeding Process

Patented Feeding Process

A conventional centerless grinder pulls the part through the machine by the work and regulating wheels. To grind a profile, the part's position is detected by sensors and the gap between the wheels is adjusted. Instead, the CAM.2 uses Glebar's patented dual-carriage linear motor part feed system. Rather than monitor and react, the position, speed, and rotation are under absolute control at all times – controlling the grind with a high degree of diameter and length accuracy. 

Two Modes of Operation (OD and Centerless)

Two Modes of Operation (OD and Centerless)

In OD mode, a narrow wheel is used and the part is fed through a hydrostatic bushing. In this mode, micro-grinding and any array of complex shapes including tapers, flats, radiuses, and threads are made possible. For less complex geometries, centerless mode incorporates the best of both worlds, maintaining absolute length and diameter control while allowing for greater speed and material removal using a wider wheel. Despite the implication, centerless mode on the CAM.2 does not use a regulating wheel, instead, it requires only a centerless fixture, greatly simplifying setup and changeover.

Automatic CNC Dressing

Automatic CNC Dressing

The CAM.2 includes automatic CNC dressing, designed for both diamond roll or single-point dressing. Using no physical templates, lead-in and lead-out tapers can be easily changed. Complete forms, including radii, can be dressed accurately into both conventional and super-abrasive wheels. The programmed wheel shape is rendered in real-time, for complete confidence in the final shape.

HMI Controls and Custom Software

HMI Controls and Custom Software

The control software is entirely developed at Glebar and is fully customizable to address your application and process. 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.
