Overview

The Vollmer VGrind 360 S extends the proven VGrind 360 platform with an integrated CNC wheel dresser, creating a self-contained tool grinding cell that can maintain precise wheel geometry throughout an entire production run without manual intervention. The integrated dresser is the defining upgrade for high-volume and lights-out production scenarios where wheel wear cannot be monitored continuously by an operator, and where diameter and profile consistency across a batch of thousands of tools must be guaranteed by the process itself.

Like the standard VGrind 360, the 360 S features Vollmer dual vertical spindle architecture with B-axis swing, carrying two wheel packs simultaneously and enabling rapid switching between grinding operations within a single cycle. The machine handles tool diameters from 1 mm to 32 mm with grinding lengths up to 330 mm. The integrated dresser works with diamond dressing rolls profiled to restore the wheel geometry to specification automatically.

The VC 720 control system coordinates the grinding cycle and dressing cycles seamlessly, applying automatic dimensional compensation after each dressing pass to account for wheel diameter reduction. This closed-loop approach ensures that tools ground at the beginning of a production shift and tools ground eight hours later during lights-out operation have the same dimensional outcome.

The VGrind 360 S is fully compatible with Vollmer Robo2Go automation and other standard robot interfaces. Combined with the integrated dresser, this creates a production cell that can run extended overnight or weekend cycles with minimal human intervention, substantially reducing cost per tool for high-volume programs.

Strengths & Limitations

Strengths

Integrated CNC wheel dresser enables fully unattended production with consistent wheel geometry across entire batch runs
Automatic dimensional compensation after dressing eliminates manual offset entry and maintains batch-to-batch size consistency
Dual vertical spindle design reduces wheel change time on multi-operation grinding programs
Self-contained grinding cell with dresser reduces floor space versus a separate dedicated dressing station
VC 720 control coordinates grinding and dressing cycles transparently, with full documentation for batch traceability

Limitations

Higher capital cost than the standard VGrind 360 requires high production volume to recover the dresser system investment
Integrated dresser adds mechanical complexity and introduces an additional maintenance item
5-axis configuration does not provide the sixth rotary axis available on some premium competing platforms

Best For

High-volume carbide end mill and drill production requiring lights-out operation with guaranteed dimensional consistency ISO 9001 and AS9100-certified tool manufacturers needing automated process control and batch traceability documentation Aerospace and medical device tool suppliers where batch-to-batch tool diameter consistency is a contractual requirement Tool grinding operations running overnight or weekend shifts where operator wheel monitoring is not feasible

Frequently Asked Questions

01 What is the key difference between the VGrind 360 and the VGrind 360 S?

The VGrind 360 S adds an integrated CNC diamond roll wheel dresser. This dresser automatically restores grinding wheel geometry during production runs, enabling lights-out operation with maintained dimensional accuracy. The base VGrind 360 requires manual or offline wheel dressing.

02 How does the automatic wheel dresser maintain tool size consistency?

After each dressing pass, the VC 720 control automatically calculates the reduction in wheel diameter and applies an offset compensation to all subsequent grinding moves, ensuring tools ground before and after dressing have the same final dimensions.

03 How often does the wheel dresser activate during production?

Dressing frequency is programmable by fixed part count, time interval, or measurement result. For most carbide end mill production, dressing intervals of 20 to 100 tools per cycle are typical.

04 Can the VGrind 360 S be upgraded from a standard VGrind 360?

The integrated dresser on the 360 S is a factory-fitted option, not a field retrofit. Customers who anticipate needing the dresser should specify it at time of order.

05 What robot loading systems are compatible with the VGrind 360 S?

The VGrind 360 S is compatible with the Vollmer Robo2Go robotic loading system and supports standard I/O and fieldbus interfaces for integration with third-party industrial robots.
