In modern CNC production, measuring instruments are just as important as machines, tooling and fixtures. If tools are not measured correctly, or offsets are set “by feel”, you pay for it in scrap, rework and lost machine time.
High-quality measuring instruments for CNC machines, such as tool presetters, tool offset sensors and tool measuring systems help you:
• Set tools accurately before they reach the machine
• Reduce or eliminate test cuts
• Keep spindles cutting instead of waiting for setup
Leading suppliers have shown that adding a tool presetter to the workflow can make machining faster, more accurate and more efficient by presetting tools for the next job while the machine continues cutting.
At Duroc Machine Tool, we help you select and integrate measuring instruments that match your machines, your tooling and your production strategy.
Why measuring instruments matter for each role.
For the Hands-On Operator
• Easier, more repeatable tool setups
• Clear digital or optical feedback instead of guesswork
• Less risk of breaking tools during touch-off or test cuts
For the Operational Optimizer
• Shorter setup and changeover times
• Fewer manual inputs and less operator-dependent variation
• More stable processes and better use of machine capacity
For the Strategic Owner
• Lower scrap and rework on high-value parts
• Higher spindle uptime and better ROI on machines
• A more controlled, data-driven production environmen
Tool presetters, measure tools outside the machine.
A tool presetter measures tool length and diameter outside the machine, so tools arrive at the CNC with known values and correct offsets.
Modern presetters typically offer:
• High repeatability, often around 1 micron or better on advanced systems
• Rigid mechanical design for long-term accuracy and stability
• Camera-based vision systems for measuring cutting edges and tool profiles
• Intuitive software interfaces that guide the operator through the measuring process
Benefits in daily production:
• Tools can be measured and prepared while the machine is still running
• Test cuts and manual touch-offs are reduced or eliminated
• Tool data can be transferred digitally to the machine control or tool management system
For operators, this means easier setups. For production managers, it frees up spindle time and supports more predictable planning
Tool offset sensors. Safe touch-off at the machine.
Tool offset sensors (sometimes called tool setters or tool touch-off sensors) are mounted on or near the machine table. They allow tools to be touched off automatically in the machine without risking broken tools or damaged workpieces.
Typical features include:
• Precision touch surfaces or 3D sensors with high repeatability
• LED and acoustic signals that guide the operator during manual touch-off
• Integration with the CNC control to automatically write tool length/diameter offsets
Benefits:
• Faster and safer tool setting compared to touching off on the workpiece
• Reduced risk of human error when entering offsets
• Consistent results across operators and shifts
For flexible job shops, combining presetters and tool offset sensors can give maximum flexibility: measure most tools offline, and still be able to set up special tools or prove-out jobs efficiently at the machine.
Other measuring instruments around the machine.
In addition to presetters and tool offset sensors, a complete measuring setup around the CNC machine might include:
• Edge and point finders for workpiece zero-point setting
• Dial indicator stands and adapters for alignment tasks
• Spindle measurement tools to check runout and spindle condition
• Balancing systems for tool assemblies to reduce vibration at high speed
Together, these instruments support more accurate setups and help maintain machine health over time
Key benefits of modern measuring instruments.
Investing in proper measuring instruments gives measurable gains in everyday production:
Higher accuracy and repeatability
• Micron-level measurement of tool length and diameter
• Stable bore and surface quality thanks to correctly set tools
Shorter setup and changeover times
• Tools prepared in advance on a presetter
• Faster touch-off with automated sensors
Lower cost per part
• Less scrap and rework due to wrong offsets
• More spindle uptime thanks to reduced non-cutting time
Better documentation and process control
• Tool data stored and reused for recurring jobs
• Easier standardisation across machines and plants
