Gear Metrology

1.

Machine Construction :

• New concept & design in Gear Measuring Machine.
• Extremely sturdy versatile & flexible
• Thermally stable massive dark granite block mounted on passive or active (optional) vibration damping.

• Frictionless non contact air bearings which are superior to mechanical bearings because there will not be any wear or tear of guide ways.
• Higher operating & measuring speed.
• All axis of the machine including tail stock made of same hard dark granite so that the thermally rugged behavior is obtained.

• Granite Guide ways are ground & lapped. Protection for guide ways against unhealthy environment such as dust is provided by the air coming out of the air bearings with pressure. 
• Only WGT CNC Gear Testers have active pneumatic vibration damping system.

• Ratio of Size of the gear / size of the foot print machine highest among the competition Gear Dia 400MM

• The high precision, air bearing rotary table is partially integrated into the machine base. The fast-reacting servomotor and a high-resolution rotary encoder, directly mounted onto the bearing system, are guaranteeing precise control and positioning of the rotary axis.

• The tailstock slide is fully counterbalanced and can therefore be easily positioned by the operator

2.

Linear Measuring system :

• Gold plated elasticized metal scale with 0.1 micron resolution.
• High tolerance to dirt, and greasy figure prints.
• Scale mounted directly on granite hence the scale thermally replicates the base material eliminating need for compensation.

3.

4.

D.C servo motors: High responsive & high quality D.C servo motors .Proven in thousands of CMMs and Gear testers all over the world

5.

CNC Controller :

• 4 axes industrial Computer based CNC controller System.
  Both  CNC Control & Gear Analysis functions integrated in one Industrial PC .

6.

Software Features : 

• Windows XP based graphically supported user interface for easy software operation 
• Gear Parameters:  Profile Errors, Leads Errors, Pitch Errors, Crowning, Tip Relief, Root Relief, Fillet Radius, Topography, Contour, Run-Out Errors, Over Pin/Over Ball Dimension, Tooth thickness, Tip & Root Diameter, All teeth Measurement on Spur & Helical Gear [External/Internal], Cluster Gear

• T-Shaft - Software facility for dimension shape & position deviation for symmetrical work pieces. Evaluation of straightness, evenness, coaxiality, roundness, cylindericity, angular deviation, parallelism, gear bore diameters, taper bores and distance according to DIN/ISO 1101.

• Measuring Cycle & Accuracy: Fully Automatic measuring cycle with short measuring time
• Direct measurement of DOP possible only on Wenzel Machines
• Machine has facility for temperature compensation & correction

• Complete software packages for following measuring tasks are available:

Accuracy Tests: Gear Measurement ACCURACIES & REPEATABILITY Tests  Will be carried out as per international standards (VDI/VDE   2612 /2613 group -1)  using calibrated artifacts (masters).
