PREC 20/ 30/ 40/ 60/ 80 CNC Gear Measuring Center

prime

A. Applications:
Model PREC 20/ 30/ 40/ 60/ 80 gear measuring machine can perform special measuring tasks of small and medium module gears and allows accurate inspections of tooth profile, helix and pitch deviations on the cylindrical gear, as well as radial runout on the gear rings. It is ideal device for workshop or inspection room in the automobiles, motorcars and electric tool industries.

B. Features:
• High measurement accuracy and compact construction: Applying the 4-axes measuring technology, this machine is provided with high performance AC servo motors (from Japan) as the drive units. In addition, each axis is equipped with a high precision encoder. Thus the measuring accuracy is greatly improved in this full closed-loop control system.

• Complete measuring software functions: The measuring items can be selected according to the workpiece to be tested. This user friendly software package provides automatic evaluation of cylindrical gears in accordance with ISO1328 --International Gear Accuracy Standard or DIN standard. The special functions in the measuring software also include evaluations of K charts for profile and lead, profile barreling Cα, and tooth crowning Cβ.

• Automatic measuring cycle with convenient operation: The measuring process is fully automatically in just one set-up. This guarantees high measuring efficiency.

• Clear viewing of control panel: Each moving part action of this machine is controlled via joystick or pushbuttons on the control panel. The control panel LED indicators for operating conditions (NORMAL, OVERTRAVEL) in each axis giving clear and convenient operator guidance.

• Stylus collision protection: To prevent the stylus transducer from damage in case of collision.

Functions of standard Gear measuring software

Evaluations of tooth profile & multi-section profile deviation (Fα, ffα, fHα, Cα)
Helix and multi-section helix deviation (Fβ, ffβ, fHβ, Cβ)
Pitch deviation (FP, fPt, fp3) and radial runout (Fr) on cylindrical external gears.
Calculations of profile modification (fFu, FKo) and helix modification (fu, fo) are supported. Also available are evaluations of tooth data on gear hobs, shaping and shaving cutters and internal gears with top diameter Φ30 mm.

L30A/ L45 CNC Gear Measuring Center With 3D Sensor

Application :

In combination with the standard software module,the model L30/L45 gear measuring centre is designed to check cylindrical gear.The optional measuring software modules include hob,worm gear,spur and spiral bevel gear packages etc.In addition,the special extended measuring functions are available on request.

Features:

Compact construction and 4-axis measuring system with high measurement accuracy and stability,HEIDENHAIN linear and angular encoders,TES HIGH PRECISION INDUCTIVE PROBE MADE IN SWISS (3D probes are available on request) as well as ball rolling guideway.
Newly-designed motion control card in the CNC system and closed loop path control for DDR/DDL motor drive.
The powerful measuring functions:The test item can be selected according to the workpiece to be tested. This user friendly measuring software allows evaluation of cylindrical gears(incl.K-chart,profile crowning and crowning in tooth trace direction) in accordance with GB11095-2008,DIN3962-1978,ISO1328 and AGMA-2000-A88 standard.
This measuring centre permits the checking of alll test items such as profile and helix deviations on freely selected tooth in one set-up. The evaluation range of the test curve is defined on a mouse drag action and the measuring velocity can also be controlled in the software. The measuring cycle is automatically controlled by microcomputer.
Visual parameter input and multiple print chart formats for customer choice. Data calculation and testing chart can be updated when the measuring parameters modified and middle data can be saved at customer's request for further analysis.
