Features

  • Our lineup includes one, two, and six-axes machines. We realize the highest level of machining precision, productivity, and operability
  • Front and rear axis twin drive system
  • Comes equipped with NC “Ez-Panel” with PC specifications. Comes with GUI (Graphical User Interface) that offers high operability.
  • Spindle variation developed for specialized machining
  • By using various options in addition to outer pin machining in external machining, we have realized dimensional precision and counterbore machining precision within ±0.030 mm, taking into account the cutoff parts of small workpieces and relativity to patters (actual results under conditions at Roku-Roku).

EZ-Panel

Comes equipped with a machining program drawing function. This enables Comes equipped with a machining program drawing function. This enables checking drawing of the machining progress status, as well as restarting the program, and doing direct format conversion. A wealth of functions needed on site are available.

1) Machining Status Screen
Displays information about tools being used and programs that are running. Check the machining status at a glance, including the progress of machining.
ezpanel

2) File Management Screen
This screen is for selecting machining programs and managing files. The Windows format makes it easy to understand, in order to easily copy, edit, and delete files.
ezpanel

3) Drawing Screen
This screen draws and displays the selected machining program. When a tool is broken, the program can be restarted by clicking directly from this drawing screen. It is also possible to convert program formats with a simple operation, making it easy to convert to our format and make version settings.

[Option] Machining Range Setting Function
This function makes it possible to set the range for the part you want to machine on the drawing screen, in order to extract a program for that part. This makes it possible to easily do partial machining and restoration.

4) Cutting Conditions Screen
This screen is for editing cutting conditions. Editing can be done while referring to the program. It is also possible to easily extract cutting conditions by registering cutting conditions in a data bank in advance. Furthermore, it is possible to set deep drilling cycles for each tool diameter.

[Options]
● K-Function
This function registers the amount of wear on tool diameter according to cutting length in advance, so that corrections according to the cutting length can be set automatically during operation. It is possible to continue machining without worrying about tool diameter wear, thereby improving productivity and realizing high-precision machining.

Features

Tool Breakage Detectors

The optical sensor constantly monitors tools that are currently being used to do machining. When a tool breaks, it stops the machining center and displays the broken part on screen. This enables quick recovery work, promising benefits such as improved productivity and reduced rate of defects.
*Only supports pressure foot for inner pin machining

Board Removal Mechanism

The board fixed in place with a stack pin can be quickly and easily removed. Removing the board in a shorter time helps increase productivity. A single unit is compatible with both the method of pulling down the stack pin and the method of pushing up the board.

Small Piece Machining Function

By combining a pressure foot with software, we have realized external dimensional accuracy of ±0.03 mm with a small workpiece 10 x 15 mm (actual results under conditions at Roku-Roku).
