Double Flank gear rolling test is generally included in final acceptance test. A gear tested on Double Flank Gear Tester is normally the indication of good running properties of the gear and is adequate assurance about the quality of gear.

The readings taken are the validation of center distance between two gears to be inspected or between one gear and one master gear meshing without backlash during one complete rotation of gear.

This is an Omniversal Chamfering, Pointing, Pointing With Radius, rounding & crown chamfer for Internal & External Gear or Spline. It can even chamfer helical & straight gear & half chamfer for RH or LH Ring Gear.

This Machine is a must for Production Shop Prototype gears, pre production batch and small gear shop manufacturing variety of gears and spline.

• Chamfer & Deburring prevent nicks type damage during handling


• Chamfer & Deburring prevent Heat Treatment Distortion

• Self centering tool make equal chamfer at both end.


• Rolling type tool looking like a shaping Cutter gives better tool life.


• Tool construction compensates for width variation of face up to 0.20 mm.


• Automatic tool hunts if gear does not engage with tool.


• The machine has two slides, one horizontal slide for chamfering operation & one vertical slide for deburring operation.


• After setting, the cycle is automatic i.e. only loading unloading is manual

• DGB is a system to remove nicks & burr for heat-treated gears. DGB is the only system that makes economic sense. DGB cannot make a bad gear good but can make a good gear better by removing its nick & burr.


• COST EFFECTIVENESS
  DGB does not require a major capital investment. Any small gear shop with good volume can justify the cost. Even though DGB tool will last through thousands of components, the life will depends on a variable, the amount of nick and burr it has to remove.
  User can run 100% gears through the process and check on sampling basis. This increases master gear life, improves time and gives constant quality of gear.

• Comparison to Other Process (EDM) available in market, the basic and very important advantage is that in EDM process the point where the nick burr is removed created a soft spot because the temp. at which nicks and burr are to be removed reaches to the melting temp. of steel and there is no control on the cooling process. Therefore creating soft spots which is vary dangerous for gear.


• The burr and nicks are identified by checking an double flank tester in close mesh with master gear. The nicks and burrs are removed by hand stoning and or by pencil grinders. This process is laborious and quality depends upon operator skill. In DGB process the orignal hardness of gear remains unchanged.

• User who hard gear hone they face a great problem with nicks and burrs as these are hard and work as crushers on the epoxy bonded abrasive wheels which loose their form. Therefore requires redressing & reducing wheel life.

• Contactless & high resolution measurement


• High EMC & ESD stability


• Solid housing & complete sealing


• Protection class IP 68 & completely sealed


• Rotational direction recognition high rotational speed robust not sensitivity to dust

• Position and Speed measurement of the main spindle in lathes, grinding and milling machines


• Speed and position measuring in HSC Spindles (High Speed Cutting)


• Electronic Synchronization of helical spindles


• Hollow Shaft Encoder


• Angle measurement in radar equipment


• Measurement of speed and position in test stands

Internal hone achieve a high output of gears between re-dressings and high rate of metal removing.

External honing wheels have all the qualities of internal hone but are not dressable.

Supply Diamond coated gear profile and Tip Dresser. These dresser are high quality and give long life.
