Super-precision gear grinder SUG SERIES

Machining of serration punches
and spline gauges

&#; Serration punch machining

Machining of serration punches and spline gauges is possible with a minimum resolution of 1/100,000° and indexing accuracy of ±0.3 sec. when the super-precision indexing unit is mounted.

&#; Example of serration punch made by mirror surface grinding

Profile accuracy: ±3μm, Surface roughness: Rz 225nm, Ra 45nm (material: SKH55)
Unconventional accuracy and quality revolutionize the production of drive parts.

&#; Helical gear grinding

Indexing in the minimum setting units of 1/10,000° and table rotation (up to ±45°) enable helical gear grinding with accuracy of the new JIS Class 1.

&#; Bias correction of helical gear tooth profile is possible.

The bias correction function is provided, which is necessary in tooth tracing of the crowning shape. The pressure angle of tooth profile can be corrected as required at the tooth profile inlet, center and outlet.&#; &#; &#; &#; &#; &#; &#; &#;

&#; Example of helical gear electrode (oxygen-free copper) made by grinding

Helical gear electrode used for cold forging die
Machining up to the module 0.3 is possible.
Machining accuracy: New JIS Class 1, Material: Oxygen-free copper

&#; Example of large-diameter helical gear made by grinding

Accurate indexing with high rigidity at the machining point is possible. A helical gear with a size of &#;φ190×80&#; can be machined with an accuracy of the new JIS Class 1.

&#; Master gear machining

&#; Master gear machining

Technology developed in accordance with the Strategic Foundation Technology Improvement Support Operation
Machining of master gears with unprecedented accuracy is possible.

&#; Master gear measurement

Manufacture of highly accurate master gears is possible by unconventional machining and evaluation methods. (for details, please consult the Nagase sales and engineering division)

&#; Super-precision multi profiler NGA-84

Five-axis controlled machine for fabrication of the free curve of the internal tooth and internal diameter of the plate forging/drawing dies.
The internal diameter and internal tooth containing a curved surface of a drawing die conventionally finished by manual work can be mirror-finished by this machine. By mounting a vertical indexing unit with the minimum indexing angle set to 1/100,000º and a super-precision grinding wheel spindle with a rotation angle of 1/10,000º, the affected layer produced after wire electric discharge cutting is removed completely and carbide dies with uniform and accurate shapes are manufactured.

PIONEER supply professional and honest service.

&#; Super-precision vertical gear grinder GC

The super-precision vertical gear grinder is compliant with large-diameter workpieces within φ300 through φ.
Simultaneous 4-axis/5-axis CNC control enables helical gear machining and various crowning bias corrections. This machine is equipped with an originally developed indexing unit with a minimum indexing resolution of 1/10,000º (indexing accuracy±0.3 sec.). By employing a non-backlash mechanism and hydrostatic bearing structure, high machining point rigidity and accurate machining are achieved, and unconventionally high efficiency is achieved as well.

&#; Super-precision small-size indexing unit SPI-01

The super-precision small-size indexing unit has been developed for machining of small-size/small-diameter serration punches and spline gauges. The indexing accuracy is within ±3 seconds to the minimum resolution of 1/10,000º. When mounted on Nagase super-precision forming grinders and micro processing machines, not only gear machining but also various other kinds of machining are possible (for details, click here).

&#; Vertical rotary indexing unit

This rotary indexing unit enables ultra-accurate indexing and rotation. The minimum indexing angle suggested is 1/100,000º. There are a vertical type and a horizontal type, both of which can be mounted on different types of Nagase super-precision machines (Nagase has manufactured the units for the range of φ300 through ). We will make recommendations about detailed specifications and accuracies according to customer&#;s required machining. (for details, please click here.)
