Automobile engine-related measuring machine

Crankshaft

Crankshaft balance measuring and correction machine

This machine measures the imbalance quantity and direction (angle) by using electric micrometer and corrects the balance automatically.

The cleaning is done inside this machine before the measurement and after correcting the balance.

Crankshaft total measuring machine

This machine measures each part of crankshaft and marks the parts.

This in-line machine measures Journal, Pin diameter, Pin stroke, Circularity of Pin/Journal (radial difference comparison method) and the Pin position distance, and result makes the specified making on each work piece based on the measurement.

Crankshaft gear checker

This machine measures the O.B.D., run out and dent for balance shaft gear of crankshaft. The measurement is made by engaging the work piece with the master gear.

Crankshaft shape measuring machine

This machine measures circularity, cylindricity, concentricity, pin stroke, pin phase, straightness and taper angle of each outer diameter of the crank shaft, and longitudinal length. It is possible to print out the shape data such as roundness and cylindricity.

Crankshaft measuring machine

This machine is an automatic equipment which measures the dimensions of the crankshaft, and determines the classification of the work piece. Also, is possible to mark the rank for each axis.

Camshaft

Camshaft measuring machine

This machine measures the outer diameter of the journal portion of camshaft, the maximum and minimum diameter of cam portion. The flexible head with long displacement enable you to measure various dimensions.

Cam shape measuring machine

This machine measures the shape (profile) of cam portion of Camshaft. It is also equipped with chatter measurement function. It can print out shape data.

Cylinder block

Cylinder block crank hole diameter measuring machine

This machine measures the crank-hole diameter of cylinder block by using an electric micrometer and automatically makes a judgment by a specified method. It makes temperature correction by measured machine temperature and work temperature. In addition, it performs the mastering if machine temperature changes more than 2ºC.

Cylinder block bore hole measuring machine

This machine measures the bore diameter of cylinder block by an electric micrometer and automatically makes a judgment by a specified method. It measures machine temperature and work temperature to make temperature correction. In addition, when machine temperature has changed more than 2ºC, the mastering measurement is made. The correction signal for honing sizing is provided as an output. It outputs the correction signal for honing sizing.

Cylinder block crank hole diameter deburring measurement and marking machine

This machine performs deburring of crank hole after the boring process of cylinder block is finished. Next, it measures each bore’s size by an electric micrometer and marks ranking after making OK/NG judgment.

Piston

Piston measurement machine

This automatic machine measures the piston’s outer diameter, inner diameter, weight and the ring groove diameter of pinhole. It marks the rank of outer and inner diameters and convey (unload the parts) to a predetermined position. This machine discriminates the model by image processing system.

Cylinder Head

Cylinder head measuring machine

This machine measures the lifter hole inner diameter, seat hole inner diameter and guide hole inner diameter of intake and exhaust cylinder head by an electric micrometer, and makes a judgement OK or NG.

Connecting Rod

Connecting Rod measuring machine

This machine measures the large end, small end and weight of the connecting rod, then it marks ranking based on these results. It can support carrying out chute setup by rank, and also transport by a robot.

Turbo

Turbine wheel / compressor wheel balance measuring and correcting machine

This machine measures the imbalance of the turbo turbine wheel and the compressor wheel. Correction processing is also possible based on the calculation.

Engine assembly

Cylinder head ASSY tappet selection machine

This machine measures the predetermined size of the camshaft, and the cylinder head Assy being assembled. According to the size calculation, select the tappet with proper thickness to make proper clearance between camshaft and tappet when assembling.

Cylinder head ASSY Clearance Checker

This machine checks if the clearance between cam and tappet under the condition that the selected tappet, the camshaft and the cylinder head have been assembled.
