GrindSmart® 660XW

Description

The GrindSmart®660XW has been designed for rotary cutting tool applications ranging from diameter 0.1 to 12.7mm in an amazingly compact layout which includes a large capacity tool loader and a high-speed wheel changer with 6 wheel-pack positions. The machine features the latest linear and torque motor technology on each axis, as well as a 14kW synchronous spindle motor. All these components are cooled with the same coolant oil providing a perfect thermal stability, unbeatable accuracy in production as well as extremely good surface finish on the tools.

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

  • The machine features 4 linear and 2 rotary axes. The unique aspect is the workhead which is mounted on a CNC linear axis. Tool grinding and the Rollomatic peel grinding process are combined.
  • Ultra-Efficient Lean Grinding Process allowing the complete tool grinding in one single setup.
  • Innovative steady rest systems designed for grinding endmills as well as for drill point grinding.
  • Efficient utilization of shop-floor space – up to one-third less than our competitors.
  • The high‐efficiency grinding spindle is synchronous and is rated 20 hp. It offers better flute finish and improved grinding stability
  • The thermal stability is exceptionally good due to an innovative 6‐axis design and double‐skin coolant enclosure.

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
• 6-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 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

SMART TEMPERATURE SENSORS

The Smart Temperature Sensors consist of four sensors located inside and
outside the machine to ensure continuous temperature monitoring. This allows the temperature of the coolant oil and the ambient temperature of the working area to be analyzed.

• Analysis of temperature data from the entire production environment

SMART ENERGY METER

The Smart Energy Meter is a meter that allows the energy consumption of the machine to be monitored through RConnect.

• Access to the machine’s energy consumption data for statistical purposes
