Simple to operate machine with the operator in mind. Reduced setups are a result of a thoughtful design of the machine. Independent top and bottom slide controls, simple work rest blade adjustment, up to 15 HP motor driving a precision twin grip spindle in a small package. Fully customizable interface geared to enhance productivity through the use of automation.
The hard chrome plated cast iron slides are dovetail ground to provide superior rigidity when positioning the regulating wheel. Both top and bottom slides can be positioned independently reducing setup times dramatically.
A 15HP motor drives the 9" (228 mm) diameter x 8-5/8" (219 mm) wide grinding wheel mounted on a twin-grip super precision spindle. The workhead assembly design allows a single operator to replace the grinding wheel in under 15 minutes.
The TF-9DHD can be built on an available 2,000 pound granite bed for superior thermal stability and vibration control.
A simple HMI touch screen can be tailored to address your process. We fully customize the interface to adapt to installed inspection systems, automation with the sole purpose of making the machine simple to operate.
Remote connectivity simplifies troubleshooting and maintenance.
Designed to part specifications and integrated with machine controls. Custom feeding is available built to part specification.
Built specific to the part, Glebar offers a variety of conveyors which move parts through the process seamlessly and quickly.
Uses a formed template to dress shallow shapes into the grinding wheel. An auto dress version of this dresser available.
Uses a formed template to dress shallow shapes into the regulating wheel.
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.
Post grinding, system is integrated into the cell to pressure clean parts.
Both Z and X axis of feeder have velocity and position control set on the machine touch screen.
Automatically picks parts from trays, loads into machine, unloads and places back to parts tray. Fully guarded and interlocked access doors. Robot arm incorporates two grippers for staging the loading and unloading during the grind cycle, reducing idle time.
Supports and facilitates the material rotation at the entry and exit sides of the grinding machine. Typically used in a thrufeed operation.
Available in manual and hydraulic version.
30 gallon capacity with two removable settling tanks centrifugal pump & filtration package
Wire 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 finished part.
Glebar prides itself on selling precision grinding machine system solutions, tailored to your specific needs. Below is a small subset of applications, performed on this machine, that Glebar has provided solutions for over the years.
Narrow work wheels prevent generating tapers over 4" requiring multiple setups to generate the shape. Highly skilled technicians are required to ensure proper setup. Upper and lower slides are strapped, preventing the regulating wheel and work rest blade from being adjusted independently. Wheel dressing is applied manually, which leads to inconsistent wheel conditions. Blade sizing is conducted manually leading to variability in setup longevity.
Deliver a process that can grind up to 8" tapers on guidewires in one pass while maintaining quality and repeatability. Decrease downtime related to setup and complicated changeovers. The process must meet CE Certification standards for operator safety.
Hydraulic dress cycles require high operator input reducing their efficiency. The traverse rate of the dressing tool is difficult to establish affecting surface quality. Inconsistent dressing of the work wheel reduces machine efficiency and can lead to higher scrap rates.
Develop a process to dress the regulating and work wheel that improves operator and machine efficiencies, improves control of the traverse rate, maintains a high-quality part, and reduces scrap rates.
Manufacturers use grinding machines with a narrow work wheel requiring several passes to reduce the diameter and achieve acceptable surface finish. Thus creating longer cycle times. Machines are difficult to adjust for setup and changeovers requiring highly skilled technicians. Heavy material removal in a short distance deforms thin walled tubing and causes burns.
Deliver a process with a small footprint that can grind tubes while maintaining a high quality part. Decrease downtime related to maintenance, troubleshooting, and complicated changeovers.
Numerous manufacturers around the world find themselves with legacy equipment incapable of meeting the changing environmental and safety standards recommended by regulatory standards. The customer in this case was operating an outdated grinding system lacking mist control with minimal safety features.
Maintain CE safety and environmental standards without hampering the functionality of the machine. Thrufeed grind 0.003”- 0.006” of material from steel tubes with a tolerance of +/- 0.0002 and achieving a superior surface finish. Lastly, the customer required the ability to connect the machine to the intranet for data gathering, monitoring and remote diagnostics.
A legacy thrufeed centerless grinder with a narrow work wheel is used. Multiple passes to grind the Nitinol tubes to size are required. Highly skilled technicians are necessary to ensure proper setup.
Long cycle time limits output per shift. Multiple passes can reduce the quality of the tubes. Shorter work wheels apply too much pressure on thin-walled tubing resulting in deformed parts.
Challenge: To size implantable spinal cord stimulation devices that deliver precise doses of electricity to targeted nerve sites for patients suffering from chronic back problems. The device is long and flexible, which made it difficult to handle. It is also constructed of dissimilar materials of varying diameters, from metal conductive rings to fine electrical micro-wires to molded polymer and plastic supports, which made grinding a fine surface finish with stringent diameter control and without damage to the parts very challenging.
