Further Advanced Automation and Operability

Operability is substantially improved by automating tooth meshing between the grinding wheel and the dresser as well as between the grinding wheel and the workpiece that has been done manually on conventional machines.

• Employed casting bed with higher damping characteristic. On the grinding wheel spindle, direct drive system is employed; a high-rigidity spindle unit that incorporates high-precision angular ball bearings is directly connected to a flat motor.
• The cutter spindle is equipped with our traction drive motor reducer that realizes smooth rotation without harmful vibration.

High-Accuracy Grinding of Optional Gear Tooth Profiles

• Achieved all-axis CNC control with 0.1 µm resolution.
• For synchronous control of cutter and table axes that is a key to generating grinding, CNC synchronous control techniques of the gear cutting machines that are accumulated over the years are applied. This achieved higher machining accuracy without the use of pitch block and indexing plate.

Shortened Setup Change and Trial Grinding/Offset Setting Times

• New workpiece grinding: simply inputting necessary data executes setup calculation and changeover through CNC control.
• Repeated workpiece grinding: setup changeover can be quickly performed by simply retrieving and running the program.
• Roundness in tooth form that occurs during bias compensation is automatically compensated by predicting it
• Burning during high performance grinding can be prevented with wet grinding

CNC Control on All Axes Eliminates the Need for Conventional Cutter Resharpening Skills

• Experience, intuition, and know-how, which were conventionally required for resharpening cutters, are no longer necessary.
• 5 types of dressings (tooth profile, second dressing, outside diameter, run-out elimination, and rear face) are fully CNC-controlled.
• The exact value of the wheel outside diameter and tooth profile information are controlled by the CNC. (The tooth profile is defined by dress-teaching function.)

• Various gear cuttings, from spur gears to helical gears having different specifications, are possible with a single gear shaper in a quite easy manner.
• Shaping various types of helical gear cuttings does not require guide replacement; helix angle is easily set as desired through NC programming.

Excellent Responsiveness And High Productivity

• Introduced a newly developed high-speed response control system and innovated the whole drive mechanism to realize a guideless mechanism.
• Maximum spindle speed of 1,000 strokes/min (ST25CNC) makes high-speed cutting possible and improves the productivity.

Incorporated with an Elevating Cutter Head

• Equipped with an elevating cutter head as standard to eliminate the need for substantially protruding the cutter spindle during machining, in which the height of machined portion of the workpiece from the table top surface fluctuates. (ST40CNC)

Drastically Shortened Setup Time Contributes to Easy Operability

• Best suited for a factory specialized in making part prototypes for automobiles or motorcycles and small shops producing different types of gears.
• Work data and cutting data can be input on the Data Input Screen in an easy manner.
• After inputting data, our conversational programming software automatically sets all the cutting conditions.
• Cutting conditions are easy to change in a manual manner.

• The 4-axis machine supports crowning/tapering in traverse (conventional and diagonal) shaving, whose settings can be made through input of numeric values only on the conversational screens in an easy manner.
• Taper amount settings and lead adjustment in plunge and underpass shavings can be set independently for the left and right tooth flanks through input of numeric values only on the conversational screens in an easy manner.

A Large Screen and Newly-Developed Software Improve Visibility and Operability

• Equipped with 10.4-inch large LCD screen
• Highly useful easy-input help feature with graphic user interface
• Double-swivel operation panel installed on the right side face, making it accessible from the conveyor side.

Visual Monitoring of Cutting Status Greatly Facilitates Cutting Condition Adjustments

• On the display you can check the cycle diagram and monitor variation in spindle load during actual machining, thus adjustment of cutting conditions is facilitated.。

Narrow-Width Design Saves Space and Readily Incorporates Into the Production Line

• The narrow-width design contributes to flexible production line configuration
• Re-examining the column’s internal structure, its rigidity is enhanced by 30% compared to the FD series
• Maintenance equipment is concentrated in a specific area to facilitate production line configuration
• Internal covers are provided for better chip removal while pipes and wirings are simplified and bundled in ducts.

• The modularized peripheral equipment and conveyor system facilitate production line configuration and its layout change. As a result, time required for setup is minimized.
• Two models are available to meet your specific production needs.

• • Type I: Flat-front type suitable for hand-loading of workpieces
  • Type II: Narrow-width type for automated production line

Vibration Suppressed Silent Shaft Enables High Speed Cutting

• The SE15A has a maximum cutting speed of 2,000 strokes/min (SE25A: 1,800 strokes/min)
• Employed silent shaft suppresses vibrations during high-speed machining.
• Super-dry pinion cutters are used.

A High Rigidity Bed and Full Measures Against Chips

• Completely sealed machining space
• Steeply inclined internal covers
• Optimally positioned internal chip conveyer
• Bed structure design aiming at better chip control
  Based on our experiences with dry-cut machining, thorough measures are implemented in this machine.

• Its narrow-width layout facilitates production line configuration. (Machine width: 1,450 mm, Depth: 2,315 mm)
• Floor space for installation is reduced by 30% (compared to our conventional model)
• Reduced cycle time of small-diameter gear cutting
• A new high-speed workpiece changer (optional)

Modularized Peripheral Equipment Facilitates Production Line Configuration

• Modularized peripheral equipment and transfer machines considerably facilitate production line configuration and layout changes.
• Minimized setup time.
• Two models available: Type I for square body; Type II for narrow-width design, suited for production line configuration.

High Speed Cutting Using Next Generation Super Dry Hob (Compliant With Recommended Cutting Conditions)

• Advanced high-speed, high-feed machining is achieved by combining next-generation super dry hobbing machine with the high-speed specification feature (optional).

A Large Screen and Newly-Developed Software Improve Visibility and Operability

• Equipped with 10.4-inch large LCD screen
• Highly useful easy-input help feature with graphic user interface
• Double-swivel operation panel installed on the right side face, making it accessible from the conveyor side.
