How True Precision Machining Achieved 1,635% ROI by Increasing Spindle Hours

For a precision machine shop, spindle hours represent productive cutting time and the capacity to complete revenue generating work. True Precision Machining needed better remote connectivity across machines serving aerospace and medical manufacturing. The opportunity was to capture more productive time from existing equipment without adding staff or machines.

SensFlo connected the machine environment through machine IP and Edge devices, beginning with simple machine state detection and progressing to controller based data extraction and ProShop ERP integration. The public True Precision Machining Success Story reports a 34.8% increase in spindle hours, a 1,635% ROI, and no increase in staff or machines.

Key takeaways

• Spindle hours increased by 34.8%.

• The reported ROI reached 1,635%.

• The improvement was achieved without adding staff or machines.

Why spindle hours matter to a precision machine shop

A CNC machine creates economic value when it is performing productive work. Available machine time can be lost to idle periods, setup delays, downtime, scheduling gaps, or incomplete visibility into actual operating conditions.

True Precision Machining’s challenge centered on remote connectivity. Without a connected view of machine activity, it is harder to measure true spindle utilization across the shop or connect production behavior with job and ERP information.

SensFlo’s guide to CNC machine monitoring for job shops explains how sensor and controller data can provide complementary views of machine state, spindle activity, alarms, part counts, and production performance.

Starting with simple machine state detection

The implementation began with a triaxial accelerometer for simple on and off detection. This provided an initial source of machine activity data without requiring the full controller connection at the first step.

The project then moved to more complex controller based data extraction. Machines were networked through machine IP and Edge devices, creating a deeper connection with equipment information. This staged approach allowed the monitoring system to begin with basic visibility and add detail as connectivity expanded.

Manufacturers considering a similar sequence can review FloControl Lite for initial visibility, FloControl Pro for deeper machine and operator information, and FloControl Premier for enterprise integration.

Connecting machine data with ProShop ERP

True Precision Machining integrated the system with ProShop ERP. This connected machine activity with a system used for broader production and business management.

ERP integration helps create a clearer relationship between jobs, planned work, and measured machine performance. The public case study does not describe every workflow created through the ProShop connection, so the article should avoid assigning specific functions beyond the confirmed integration.

The implementation also included hardware and firmware, controllers, analog data, fault codes, WiFi connectivity, on premises capabilities, interoperability, cloud based solutions, and language processing.

Recovering capacity without additional machines or staff

The strongest result in the case study is the combination of higher spindle hours and no increase in staff or machines. A 34.8% increase in spindle hours means True Precision Machining generated substantially more productive cutting time from its existing production resources.

This supports top line capacity because more spindle time can create more opportunity for sellable work when demand and materials are available. It can also support bottom line performance by improving the use of existing capital and labor.

The public result reports a 1,635% ROI. The case study does not publish the full calculation, time period, investment amount, or revenue contribution used in that figure. Those details should not be invented. The article can accurately state the approved 1,635% result and connect readers to the SensFlo ROAI Calculator to model their own operation.

What other machine shops can learn from True Precision Machining

True Precision Machining demonstrates a staged path to connected production intelligence. The project began with a triaxial accelerometer for basic machine state detection, moved into controller data extraction, networked machines through IP and Edge devices, and connected the result with ProShop ERP.

That sequence can help a machine shop establish value before expanding integration depth. The initial question is whether the machine is producing. The next questions address how it is performing, which job is running, and how measured results compare with business plans.

SensFlo’s article on measuring and monitoring spindle hours provides additional context on why spindle utilization is a central revenue metric for precision machining operations.

Frequently asked questions

How did True Precision Machining increase spindle hours?

True Precision Machining connected machines through machine IP and Edge devices. The implementation began with a triaxial accelerometer for simple machine state detection, then expanded into controller based data extraction and ProShop ERP integration. The published result was a 34.8% increase in spindle hours.

What ROI did True Precision Machining achieve?

The approved public result is a 1,635% ROI. The SensFlo success story does not publish the detailed formula, investment amount, financial period, or revenue components used in that calculation. Those details should be evaluated using the company’s internal records rather than inferred.

Did True Precision Machining add equipment or staff?

No additional staff or machines were added according to the published SensFlo case study. The reported improvement came from increasing spindle hours across the existing production environment through connected monitoring, controller data, and ERP integration.

Why is spindle hour monitoring valuable?

Spindle hour monitoring shows how much CNC machine time is spent performing productive cutting work. This helps machine shops identify unused capacity, compare machines and shifts, review scheduling assumptions, and estimate the revenue value of recovered production time using measured activity.
