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.
The CAM.2 is built on a 2,200 pound 6" (152mm) thick granite bed, for enhanced rigidity, thermal and vibratory stability.
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.
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.
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.
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.
This is done by using EtherCAT® by and large the fastest industrial Ethernet technology.
The P4K serves as a closed-loop quality control device that feeds back diameter to the control system for automatic size compensation.
Available metrology device (P4K) which can serve as a closed-loop quality control device that feeds back diameter to the control system for automatic size compensation
Enables the machine to run in centerless mode without the need for a regulating wheel or work rest insert. Together with the built in CNC dressing feature of the machine, part shapes up to 1.0" long may be plunged to size.
Parts can be sandblasted in-line with CAM.2’s positional accuracy, eliminating additional handling and a secondary operation.
Diameter contact gauge mounted on exit side of the machine measures the ground part. Diameters at several points can be measured, used for size compensation, and compared against high and low user-defined limits. Contact measurement is unaffected by coolant.
Collects and removes debri and dust from the work area.
Comes with arbor, flange with four weights and stand. Balanced grinding wheels are critical for high precision parts.
Post grinding and cleaning, the data is collected, analyzed and fed back to the machine for automatic size compensation. Measurements are shown on a trend graph on the machine control.
Built specific for the part; integrated into the cell.
High-speed with programmable positioning, allowing for the fast grinding of double-ended grinds and faster part extraction, reducing cycle time.
Provides the capability to grind nitinol wire directly off a spool. The feeder pulls and cuts wire to user determined length, and feeds it to the grinding machine.

10' (305 cm), 16' (500 cm) long wire/part loader and unloader interfaced to the machine control. Feeder will pick wires out of a bin, load them into machine, stage next part during grinding and unload finish part allowing hands-off machine operation.
Designed to add horizontal grooves to parts, this high-speed sub-spindle attaches to the Work Wheel slide for easy positioning.
Uses bushings for a burr free cut. Cutting wire after grinding provides the capability of grinding multiple short parts out of one long wire in one feeding operation, reducing cycle time.
Pulls finished part out of grind zone using gripper mechanism and places it in receiving tray. This system is ideal for handling short parts and often used in conjunction with the Wire Cutter.
