GrindSmart 630XW3 | 6-Axis Precision Tool Grinding

The 6-axis precision tool grinder GrindSmart®630XW3 has been designed for high performance and specialty tool manufacturing for both long and short batches. the productivity of this machine is higher thanks to simultaneous changing of the wheel & nozzle packs during the tool loading/unloading cycle and with the capacity to hold up to 16 wheel packs. It is equipped with linear motors, combined with the torque motor on the rotary axis, provides more benefits such as enhanced surface finish and reduced maintenance costs. The oil used for cooling and lubricating the linear motors is the same as the coolant oil. This ensures consistent thermal stability during setup and production without incurring additional energy consumption.

Smart Autonomous Grinding

Our vision of “Smart Autonomous Grinding” is to provide Rollomatic machine users with a fully autonomous machine capable of managing the production by itself with very little human intervention. A part of this ambitious project is the ability of the machine to manage the offsets to get the first parts within specification. Further items include to be able to achieve unattended production over several days within very tight tolerances an to interact with external robotic and automation systems. The Smart Autonomous Grinding program also includes machine connectivity and communication exchange systems with other equipment such as measuring machines, laser etching, etc.

Smart Setup Assistant

The Smart Setup Assistant Function was developed with the aim of achieving the
first ground tool within the tolerances. The program generates a grinding path for each operation to be performed on the blank. These grinding operations are
carried out and then measured by the touch probe measuring system, which
defines the grinding wheel corrections before the first tool is made. The blank is then ground to the geometry programmed by the operator, taking into account the corrections required to ensure production according to specifications from the first tool.

In-process Measurement

The in-process measurement function ensures that the tool remains within the
defined tolerances throughout the production process. To achieve this, several
measurements are made periodically by the touch or laser measurement system
to apply the necessary corrections, thus ensuring reliable and unattended
production over an extended time.

Advantages

6-axis kinematics offers extreme freedom of movement during machining with the possibility of tilting the grinding wheel to suit the operation. The 6th axis allows radii to be obtained with a form accuracy within very tight tolerances thanks to being able to maintain a constant grinding point.

Unique grinding capacity enables production of micro tools of Ø0.1mm and large diameter tools Ø20.0mm all with the same machine.

Universal workhead allows rapid change‐over from one family of tools to another, or from rotary to stationary tools.

Integrated and flexible handling system allows for complete automation for any application.

Efficient utilization of shop-floor space with a small footprint. Up to one-third less than competitors.

Ultra-efficient synchronous spindle motor developing a power of 14kW and torque of 23 Nm for a constant rotation and torque speed regardless of the motor load. This technology makes it possible to obtain high quality surface finishes, especially when the motor load is high.

Smart Features

SMART TOOL LOADER

The high-speed tool loader, designed by Rollomatic and integrated into the basic machine, was developed with fast setup and ease-of-use in mind. This is achieved by using pre-calibrated cassettes and clamps to hold different
diameters without resetting the position. Rollomatic automatic loaders are known to be the fastest and most reliable in our industry.
• Fast to set up
• Capacity up to 1’360 parts
• Robust, low maintenance design

SMART CHANGER

Smart Changer is an ultra-fast automatic grinding wheel and nozzle changer that offers exceptional flexibility for the production of all types of tools. The wheel changer can operate simultaneously with the tool loader, which substantially reduces cycle times.
• Increased flexibility
• 16-wheel pack capacity
• Ultra-precise wheel pack change, less than 0.002 mm
• Extended production autonomy

SMART SHANK GUIDE

The Smart Shank Guide is a tool shank guiding system that guarantees
concentricity down to a few microns at each clamping. It saves time and boosts productivity, as it is no longer necessary to probe for runout during setup.
• Exceptional concentricity accuracy, less than 0.002 mm at each clamping
• Quick and easy to set up
• Increased productivity

SMART STEADYREST

The Smart Steady Rest is a high precision steady rest for drills and other long tool blank. It provides stability in the grinding process and allows for faster feedrates.
This ensures repetitive quality of the tool throughout the production process.
• Quick and easy to set up
• Highly accurate adjustment system in 3 planes
• Consistent production quality

SMART TOUCH PROBE

The Smart Touch Probe is a contact measurement system that allows the blank
position to be defined before grinding and avoids variations during production.
The system also compensates for machine thermal drift caused by changes in
ambient temperature and for wheel wear.
• Runout compensation and core diameter measurement
• Setting assistance
• Superior stability during the production process
• Elimination of scrap during unattended production

STICKSMART®

The StickSmart® is an automatic sticking system for in-process cleaning of
grinding wheels. The «stick», mounted in a holder, is used to regenerate superabrasive grinding wheels to maintain their cutting performance.
• Extends the working life of the wheel
• Extends unattended production cycles with high-performance wheels
• Reliable and safe automatic process for the operator
• Efficient, economical and safe solution

SMART IN PROCESS WHEEL DRESSER

Smart in process Wheel Dresser is a self-retracting rotary dressing unit driven by a servo motor with a speed of up to 3,000 rpm. This feature optimizes the service life of the grinding wheels. The maximum dressing wheel diameter is 125 mm for peripheral dressing of diamond and CBN wheels.
•Extended wheel life
•Optimization of production without interruption
•Constant maintenance of the wheel profile

SMART LASER MEASUREMENT

The Smart Laser Measurement is a laser measurement unit for in-process
inspection and automatic compensation. This contactless tool measurement
option enables reliable, unattended production within tight tolerances, increased productivity, elimination of scrap and cutting-edge damages.
• Wide range of measurable diameters from 0.3 mm to 20 mm
• No need for manual tool measurement during production
• Automatic compensation for tool diameter variations
• Superior stability during the production process
• Elimination of scrap during unattended production

SMARTCHUCK

The SmartChuck is a high-precision, self-centering multi-jaw clamping system that automatically adapts to different diameters without the need for adjustment.
The SmartChuck can be used in conjunction with the automatic runout
compensation feature included in the VirtualGrind®Pro programming software to ensure optimum concentricity.
• Clamping range from diameters of 3 mm to 12 mm
• Clamping concentricity less than 5 micron
• Easy-to-change production diameters, and quick and simple adjustment
