ULTRA PRECISION SURFACE AND PROFILE GRINDING MACHINE
SGC-630α・840α究極の加工精度と高いコストパフォーマンス。「最高傑作」と評判も高い超精密CNC成形平面研削盤SGC-630α・840αseries。「超精密研削盤」のナガセインテグレックス。
Machining of workpieces in size of 600x300 or 800x400 is possible with high repeatability and submicron flatness and parallelism
Accurate infeed is possible even for high-grit grinding wheels. Furthermore, mechanical fluctuation is eliminated to achieve higher quality.
Contouring by simultaneous control of vertical/cross axes and shape fabricating by simultaneous control of vertical/longitudinal axes are possible with outstanding accuracy.
High repeatability to the submicron enables accurate grooving and form fabrication of connectors, etc.
A non-contact and polyhedral constraint static guideway, which is used in the nano machine, is fully employed in each axis.
This guideway structure is characterized by a minimum change in the traveling line as the speed changes, as well as a minimum change in accuracy even after the heavy use of the machine over a long period of time.
The actuator for driving the longitudinal axis and cross axis incorporates ultra-precision linear motor technology derived from the nano machine development. High-speed and smooth motion ensure submicron form accuracy even for 3D shapes and allow machining with nano-order quality.
The special static spindle C630/840α developed for rotational accuracy and rigidity is employed.
In addition, an original ultra-low vibration motor with a vibration value of below 0.1μm is mounted as standard equipment to achieve the highest accuracy and quality.
A change in temperature environment is a great enemy to ultra-precision machining.
To solve this problem, a covering and machining system hardly affected by ambient environment under general constant temperature environment have been established.
In addition, power consumption is reduced by about 30% compared to the conventional hydrostatic machine.
The work layout as well as arrangement, shapes and colors of keys on the operation panel have been reviewed and re-designed.
SUS is mostly used to keep the appearance over time. A full-cover model for the simple chamber has also been developed.
Various types of truers and dressers such as a swing dresser, rotary dresser, etc. for highly accurate wheel forming are optionally available. A layout structure is introduced to allow the layout of different dressers on the same table (patented).
By mounting an (optional) accurate touch probe unit, 3D measurement is possible immediately after machining. Functions similar to the latest 3D measurement machines such as verification of the contour by comparing CAD data and measurement result as well as verification by comparison of the free curve are available. Therefore, time-consuming jobs such as dismounting a machined workpiece, measuring and re-machining the workpiece are no longer required.
The latest interactive software Zero series is mounted. This software has functions for efficient routine jobs such as intuitive setting of the machining range, fingertip screen call, etc., as well as advanced setting functions to maximize the capabilities of the ultra-precision machine. Machining, using a program created by CAD/CAM software, is simplified.
The use of a newly developed ultra-precision small-size indexing unit (optional) and small-diameter spindle enables accurate indexing machining. Optionally attaching a vertical indexing unit, as requested, also enables indexing machining. The tool holder (optional) and milling unit are also available for ultra-precision micro shape machining.

The picture shows a status of machining with ultra-precision high reciprocating forming grinder SHL-315.
* NOTE: Machining with this unit requires an additional small-diameter spindle.
Various Types of Micro Machining are possible using a Diamond Tool.
Full-cover type SGC-630α and SGC-840α are ideal for sites where the influence of external temperature changes needs to be suppressed and splashing of grinding fluid, etc. needs to be prevented.
A popular ultra-precision forming surface grinder is now available in the SGC-630 and SGC-840 series.
The functions remain the same, but at a more reasonable price. The cross axes are driven by ball screws. Ultra flat surface and form grinding can be machined with outstanding accuracy.
