PQI Probing FAQs
What types of probing systems and services does PQI Probing offer?
PQI offers a full suite of solutions including inspection probes, tool-setting systems, data collection software, machine tool calibration (ISO/IEC 17025 accredited), retrofit analysis, hardware & software upgrades, as well as parts, repairs, training, and installation support.
Which industries does PQI Probing serve?
PQI supports a wide variety of industries including aerospace, medical, automotive, oil & gas, semiconductor, electrical, job shops, construction and industrial manufacturing.
What is a retrofit analysis, and when would I need one?
A retrofit analysis is a diagnostic evaluation of your existing machine tool or probing setup to determine upgrade opportunities, process bottlenecks, or performance issues. If you’re experiencing downtime, inconsistent tool setting, or outdated probes/software, a retrofit analysis helps identify and implement improvements.
What capabilities does your machine tool calibration service include?
PQI offers machine tool calibration services compliant with ISO/IEC 17025, traceable to NIST, and following standards like ASME B5.54 for CNC machining centers. Services include laser interferometry, ball-bar testing, spindle analysis, straightness/squareness/pitch/yaw measurement and error compensation updates.
How does the tool-setting service help reduce downtime or defects?
PQI’s tool-setting offerings (e.g., Renishaw NC4/NC4+, OTS, RTS) deliver high-speed, non-contact or touch-trigger measurement of tool size/length/diameter, broken tool detection, and feedback for adaptive machining — helping prevent tool breakage, ensure correct setup and keep parts in spec.
What is machine tool data collection, and how can it benefit my production?
Machine tool data collection solutions from PQI let you capture real-time performance data from probes and CNC machines (via MTGage + QC-CALC RealTime), analyze trends, run SPC, export reports and optimize processes across your plant. It enables smarter decision making and fewer surprises.
Why choose PQI Probing over installing a probe yourself?
PQI distinguishes itself by offering personalized engineering support: each client gets a dedicated engineer throughout selection, installation, training and after-sales support. With over 500 installations per year and more than 20 years of individual engineer experience, PQI supports the full lifecycle.
What kind of post-installation support and training is available?
After installation, PQI provides on-site training tailored to your team (machine operators, programmers, supervisors), printed/digital maintenance & troubleshooting materials, software updates, and ongoing engineer outreach — all included at no extra cost.
Can PQI handle upgrades of hardware and software for existing probing systems?
Yes. PQI offers both hardware and software upgrades for probing and tool-setting systems, including newer probe cycles (broken tool detection, oversized tools, corner radius measurement), improved repeatability, and integration with newer CNC controls.
How can I request a quote or begin working with PQI Probing?
You can visit the “Request a Quote” page on PQI’s website and provide information about your machine model, probe type or list of parts needing service. You can also contact PQI directly at (763) 249-8135 or via the contact form. A service representative will respond with next steps.
What is "separate system” toolsetting?
It is a non-contact tool setting system designed and mounted on repeatable bracket design inside of the machine that does not interfere with the machining envelope.
What is "retractible” toolsetting?
It is a non-contact, separate system toolsetting that enables the measurement of small tools and improves tool measurement repeatability through the use of Renishaw Blue Laser technology.
What is the impact of machine tool probing on cycle time?
Probing enables in-process control inside of a machine to capture and monitor critical characteristics on your manufactured parts. It decreases cycle times by maximizing throughput and the quality of your manufactured parts.
Can I use probing to find GD&T answers?
Yes, with advanced software packages.
Is there a standard for CNC machine tool calibration?
Standards are determined by a manufacturer. It is recommended that machine tools are calibrated after any machine impact or overload.
What kind of error corrections can be made for CNC machine tools?
Error corrections can be made in the 6 Degrees of Freedom (6DoF) including volumetric, horizontal, and vertical straightness if the machine tool is equipped with necessary control options.
Are there advantages of CNC probe scanning over single point probe?
A scanning probe is much faster in setting up a part or in taking measurements. It also provides more accurate data because of the vast increase of points taken.
How do I implement “closed loop control” for CNC machine tools?
Renishaw Central is the latest closed-loop control software for machine tools and equipment across the manufacturing floor. The software integrates and connects with your quality equipment and SPC software for an efficient manufacturing process.
What is the Equator Gage and Equator X?
The Equator Gage is a parallel kinematic robot that has a high stiffness to weight ratio that provides a high-speed, repeatable platform for part measurement. Accuracy is obtained through mastering on a known part which creates an error map for the features being gaged at the part level. The mastering, in effect, zeros out the effects of temperature and other shop floor variables.
The Equator X has this capability plus it can stand alone as a shop floor CMM.
How can I use an Equator for post process closed loop control?
The measurement data acquired by the Equator can be used to determine offsets with Renishaw Central / Intelligent Process Control (IPC) software to provide closed loop feedback to the machine tool.
