Overview
The Rollomatic SmartGrind 615XW is a 6-axis CNC tool grinding machine distinguished by its WhisperGrind technology — a proprietary approach to process parameter control that significantly reduces acoustic noise and airborne particle emission during the grinding cycle. The machine targets production environments where noise regulations, operator comfort, or cleanroom-adjacent operation is a priority, without compromising on throughput or geometric accuracy. The 615XW builds on Rollomatic's established SmartGrind platform with enhanced enclosure sealing, an upgraded mist collection system, and optimized spindle scheduling algorithms that reduce peak noise events.
The SmartGrind 615XW handles tool diameters from 1 mm to 20 mm with a maximum flute length of 200 mm, making it well-suited for mainstream carbide end mill and drill production. Its six fully interpolating axes enable all standard tool geometries including variable helix, variable pitch, and eccentric relief. The machine's WhisperGrind cycle management adjusts feed rates and wheel engagement dynamically to maintain an even acoustic profile, which in practice also reduces grinding forces and can extend wheel life by avoiding aggressive initial engagement peaks.
Rollomatic's GrindSmart 6 software platform provides the programming environment for the 615XW, with a modern touchscreen HMI and step-by-step tool geometry wizards that allow experienced machinists — not just software specialists — to develop new grinding programs quickly. The machine maintains a library of customer-defined tool programs with version control, supporting ISO 9001-aligned production documentation.
The 615XW integrates Rollomatic's standard SmartLoader automation interface, and the machine's compact footprint (approximately 2.2m x 2.0m) makes it practical for shops with constrained floor space. The WhisperGrind enclosure upgrades also contribute to a cleaner machine exterior by reducing coolant mist escape, an important factor in facilities that prioritize housekeeping and machine longevity.

Strengths & Limitations
Strengths
- WhisperGrind technology reduces operational noise by up to 8 dB(A), improving operator environment and enabling installation near noise-sensitive areas
- Dynamic feed rate management inherent to WhisperGrind also reduces peak grinding forces, extending wheel life
- GrindSmart 6 touchscreen HMI with parametric wizards allows rapid programming without specialist software knowledge
- Compact footprint fits into shop layouts where larger grinders cannot be accommodated
- Integrated HEPA-grade mist collection system maintains cleaner air quality and reduces coolant residue on machine exterior
Limitations
- 20 mm maximum tool diameter is more limiting than some competing 6-axis grinders, excluding larger shank tools
- WhisperGrind cycle management adds complexity to process parameter optimization compared to a simpler open-loop grinder
- Pricing premium over standard SmartGrind models may be difficult to justify for shops without specific noise compliance requirements

Frequently Asked Questions
01
WhisperGrind is Rollomatic's proprietary cycle management technology that modulates feed rates and wheel engagement to avoid aggressive initial contact events that generate peak noise. By maintaining smoother, more consistent grinding engagement, the system reduces acoustic output by up to 8 dB(A) compared to a conventional fixed-parameter grinding cycle.
02
WhisperGrind's dynamic feed management has minimal impact on cycle time for most tool geometries. In some cases it slightly extends cycle time (typically under 5%) but also improves surface finish consistency and reduces wheel wear, partially offsetting the time cost through better wheel life.
03
No. The 615XW is optimized for the 1–20 mm tool diameter range. For larger diameter tools (up to 32 mm), Rollomatic's NG 6300 or NG 6400 platforms are more appropriate.
04
The SmartGrind 615XW uses Rollomatic's standard SmartLoader interface, making it compatible with the full SmartLoader product range for automated loading and unloading of tool blanks and finished tools.
05
Yes. GrindSmart 6 software supports both new tool grinding programs and resharpening cycles. Resharpening typically uses a subset of grinding operations (flute regrind, end gash, relief) and the parametric wizard guides operators through defining the correct regrind parameters for a given tool.
