The Glebar Advantage

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.

Introducing the TF-9DHD

  • The TF-9DHD is an automatic Infeed/Thrufeed centerless grinder. Small in footprint, very capable grinder. Utilizing up to an 8-5/8” (219mm) wide work wheel, it is able to remove more material, faster and with better surface finishes than similar machines with narrower grinding wheels.
  • This machine is superior to competing machines in the same class due to the fact that it can run a 15HP main spindle motor in such a small package. This means more material can be removed per pass than larger machines.
  • An automated version of the manual TF-9BHD machine, the DHD includes precision bearings on the work head assembly as well as 0.1 micron glass scale feedback for closed loop position control. We fully customize the HMI interface to adapt to installed inspection systems, automation with the sole purpose of making the machine simple to operate.

TF-9DHD Highlights

Stable Granite Bed

Stable Granite Bed

The TF-9DHD is built on a rigid 2,000 pound granite bed for superior thermal stability and vibration control.

Independent Slides for Quick Setup

Independent Slides for Quick Setup

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.

Workhead Assembly

Workhead Assembly

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.

HMI Controls and Custom Software

HMI Controls and Custom Software

 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.

Accessories

Bowl Feeder

Bowl Feeder

Designed to part specifications and integrated with machine controls. Custom feeding is available built to part specification.

Conveyors

Conveyors

Built specific to the part, Glebar offers a variety of conveyors which move parts through the process seamlessly and quickly.

Template Tracing Work Wheel Dresser

Template Tracing Work Wheel Dresser

Uses a formed template to dress shallow shapes into the grinding wheel. An auto dress version of this dresser available.

Template Tracing Regulating Wheel Dresser

Template Tracing Regulating Wheel Dresser

Uses a formed template to dress shallow shapes into the regulating wheel.

In-Line Gauge

In-Line Gauge

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.

Mist Collector

Mist Collector

Collects and removes debri and dust from the work area.

Off-machine Wheel Balancing System

Off-machine Wheel Balancing System

Comes with arbor, flange with four weights and stand. Balanced grinding wheels are critical for high precision parts.

Post Process Gauging

Post Process Gauging

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.

Part Counter

Part Counter

Built specific for the part; integrated into the cell.

Pressure Washing System

Pressure Washing System

Post grinding, system is integrated into the cell to pressure clean parts.

Programmable Side Feeder

Programmable Side Feeder

Both Z and X axis of feeder have velocity and position control set on the machine touch screen.

Robot Pick & Place

Robot Pick & Place

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.

Roller Outboard Support

Roller Outboard Support

Supports and facilitates the material rotation at the entry and exit sides of the grinding machine. Typically used in a thrufeed operation.

Straight-line Regulating Wheel Dresser

Straight-line Regulating Wheel Dresser

Available in manual and hydraulic version.

Three-Stage Recirculating Coolant System
