Accura Technics Model 1210RSG

Rotary Grind Specialty
The Accura Technics 1210RSG is designed to achieve sub-micron precision levels in rotary surface grinding applications.
Simple Software
In order to achieve an easy to use human-machine interface, custom application specific software modules can be added to streamline the programming and machine setup processes.

Demanding Surfaces And Contours
Exceptional roundness, flatness, and concentricity is made possible by the precision linear axes and hydrostatic spindle coupled with the stability of the natural granite base.
Acoustic Emissions Monitoring
An optional touch detection system can be integrated into the machine / control system. This technology enables the operator to maximize throughput and increase dimensional consistency.

CNC Control
The 1210G utilizes a Bosch-Rexroth controller providing a flexible CNC platform integrated into a Windows 2000 user interface.

Simplified Part Setup
Vertical orientation provides superior part load, setup, and unload due to good workzone accessibility from the front and top of the machine.

Vertical Design
Allows for more precise part creation by eliminating the adverse effects of gravity as experienced on a horizontally oriented machine.

Optional Equipment

1. Integrated Touch Detect System

Integration of a Touch Detector / Gap Elimination module provides a deterministic method for accurately finding the surface of the workpiece. This option monitors the high frequencies emitted from the grinding process in order to “find” the surface. The unit can be adjusted such that a minimal amount of material is removed from the workpiece during a touch cycle. The graphic on the right shows the data readout for a typical touch procedure; when the level of noise exceeds the touch threshold (dotted line) the machine immediately stops infeed. Several functions can then be performed, such as writing a value to a table or executing an axis move, etc.

2. Preload Grind - Application Module

This custom program module can be used in conjunction with the standard CNC interface to provide an easy to setup and execute a bearing preload grind cycle. Method of cut, gap elimination, and other elements of a preload grind cycle are entered and saved. Once these data are set, the user is given a simple interface from which the production grind cycles can be executed. This interface also allows continual process optimization. Wheel dressing / truing and chuck grinding are conveniently activated at the press of a button, and cycle time monitoring is built in.

3. Enclosure

Full upper enclosure completely surrounds the work area providing containment for coolant and grinding mist.

4. Coolant System

Recirculating flood coolant system utilizing a self-feeding fine mesh paper bed filter (Consult Accura Technics for alternate coolant systems)

5. Mist Collection Unit

Stand-alone mist collector to remove grinding mist and airborne particles from the work area.

6. Additional Vertical Axis (W-axis)

CNC controlled vertical axis provides an additional station to allow multiple operations in one machine setup.

Accessories

1. NIB Type Dresser(s)

Modular single point diamond NIB dressing station(s) can be mounted in multiple configurations.

2. Chucks

Mechanical (collet and hydraulic), magnetic, air actuated, vacuum, or custom chucking can be added.
