ProgrammingProgramming

G-/M-code programming is difficult on
a 5-axis machining center.
Interactive functions do not allow machining that
utilizes our in-house know-how.

OperationOperation

The operation panel position
cannot be adjusted,
making it difficult to operate.
It is hard to understand where to
operate to reach the desired screen.

Machining checkMachining check

Due to fear of a collision,
operation check takes time.
Milling condition setting takes time.
To prevent long workpieces from chattering,
we have to perform machining by reducing productivity.

Continuous machiningContinuous machining

Machining accuracy changes during
long-duration machining.
Machine accuracy correction is difficult.
Not sure how often to perform
machine accuracy correction.

Quality managementQuality management

Manual measurement has
variable accuracy depending
on the operator's skill.
It is a hassle to transfer a machined workpiece to a 3-D measuring machine.
Programming for in-machine
measurement of complex shaped
parts is too difficult.

MaintenanceMaintenance

Suddenly the machine breaks down
and production stops.
Maintenance frequency varies
depending on the operator.
Cleaning the tank is a hassle, and the machine stops during cleaning.
If neglected, it can rot and
produce a bad smell.

AutomationAutomation

We want to automate,
but there is no one who can
create robot programs.
There is no wide space for a robot.
High-mix, low-volume production requires frequent setup changes, and even automation does not improve operating rates.

Thermo-Friendly ConceptThermo-Friendly Concept
Accepting temperature changes to achieve stable high accuracy machining

Machining accuracy of the workpiece changes significantly due to ambient temperatures around the machine, heat generated by the machine, and heat generated in machining.
The Thermo-Friendly Concept is the unique concept of “accepting” these temperature changes so that high accuracy can be achieved in normal factory environments with no special measures by the user.

Achieving stable measurements without relying on the skills of the operator

On-machine 3-D measurement of workpieces on a 5-axis machining center and multitasking machine

NC Gage
Process integration of 3-D measurement. Setup change unnecessary, significantly reducing lead time.

When measuring large 5-axis or multitasking workpieces with a 3-D measuring machine, setup changes are required because the workpiece must be repositioned multiple times on the measuring machine using a crane according to the measurement points.
Furthermore, if the measurement result is not acceptable, the workpiece will have to be reattached to the machine for remachining.
Performing 3-D measurement on the machine enables speedy work without the need to load and unload workpieces or change setups for each measurement point. Once a measurement program is created, the same workpieces can be measured automatically.

NC Gage
  • Intuitive operability and a wide variety of measurement options.
  • Measurement programs are automatically generated through teaching.
  • Measurement of geometric errors is also possible.
