Surface Grinding
Cross pitch or traverse feed allows surface grinding. B/F reversing positions are easily set by teaching operation.
WAZA840-NC Splash guard + Rear splash guard
NAGASHIMA original structure
The workhead and column are integrally structured to enhance infeed accuracy and rigidity for heavy duty grinding.
Operator friendly CNC Machine
WAZAμ is equipped with a FANUC. High versatility and operability are achieved by combining the FANUC control with our original interactive software.
Increasing Operational Efficiency with a Simplified Operation Screen
WAZAµ's interactive screen is so simple. It changes the concept of CNC machine. Even an operator, who has never used CNC machine, can manage with ease. Machining conditions can be set up in one time to start automated operation.
"Handwheels" for High Performance CNC Machine
To overcome the image of "non-operator-friendly" of CNC machine, WAZAµ provides a versatile system, such as handwheels for both longitudinal and cross axes. Instantly switch over from CNC to versatile operation. This CNC machine even has high productivity in multikind small-lot production.

Standard Grinding Features
Surface Grinding
Cross pitch or traverse feed allows surface grinding. B/F reversing positions are easily set by teaching operation.
Program Grinding
Multiple surfaces and grooves are processed at one time.
Groove Grinding
Grooves of two different heights, depths, and pitches are processed at one time.
Contour Grinding
Shape input allows contour grinding. Three different shape programs (rough/medium/finish) can be set at one machining.
Dressing Devices ※1
Maintains grinding wheel shape automatically and constantly during machining
Point Dresser
Single point dresser enables automatic parallel dressing during machining. Automatic machining can be performed without concerning about grinding wheel dulling.
※It is a standard equipment when the dresing device is mounted.
Rotary Dresser
Rotary dresser enables forming of grinding wheels and automatic dressing during machining. Multiple grinding wheel shapes can be formed continuously.
※Optional
※1 The width of magnetic chuck is 100mm smaller with a dressing device.
