The Challenge

A Thousand Different Parts, One Quality Standard

General mechanical manufacturing is defined by variety. This week it's a batch of precision shafts, next week it's bearing housings, the week after it's custom pins for a new assembly. Each part has different dimensions, tolerances, and inspection requirements.

The measurement solution must be equally versatile. A single air plug works for one bore diameter. A manual bench with interchangeable fixtures handles a family of parts. A semi-automatic station with electronic probes covers multi-feature inspection. The right choice depends on batch size, tolerance class, and how often the part changes.

What doesn't change is the accuracy requirement. Whether it's a prototype or a 10,000-piece run, every part must meet the drawing specification. And the measurement system must prove it, with documented, repeatable results.

PFL measuring bench — versatile fixture for multi-part families

Our approach: We start with your part mix, how many different parts, what tolerance classes, what batch sizes. Then we design the most cost-effective solution: a simple hand gauge for quick checks, a manual bench with changeable fixtures for part families, or a dedicated station for high-volume runs. Every system uses the same proven air gauging and electronic probe technology that serves our automotive and aerospace customers.

Component Types

What We Measure in General Mechanics

The full range of turned, ground, and machined components found in every mechanical workshop and production facility.

Shafts & Spindles

External diameter, runout, and cylindricity on ground and turned shafts. Air rings for non-contact OD measurement. Electronic probes for length, shoulder position, and groove dimensions.

Tech: Air Rings + ProbesTol: IT5–IT7

Bearings & Bearing Housings

Bore diameter and roundness for press-fit or interference-fit bearing seats. Tight control of bore geometry ensures proper bearing preload and extends bearing service life.

Tech: Air PlugsTol: IT5–IT6

Gears & Gear Blanks

Bore diameter and face runout on gear blanks before hobbing. Post-grinding bore inspection on finished gears. Concentricity between bore and pitch diameter controls gear mesh quality.

Tech: Air + ElectronicTol: IT5–IT7

Bushings & Sleeves

Internal and external diameter on bushings, guide sleeves, and wear rings. Simultaneous ID and OD measurement verifies wall thickness uniformity, critical for press-fit and sliding applications.

Tech: Air Plugs + RingsTol: IT6–IT7

Pins & Dowels

Diameter and straightness on precision pins, dowel pins, and locating pins. Small-diameter air rings or electronic probes for fast, accurate go/no-go sorting and diameter classification.

Tech: Air Rings / ProbesTol: IT5–IT6

Turned & Ground Parts

Multi-diameter inspection on complex turned parts: OD steps, bore diameters, shoulders, grooves, and chamfers. Manual benches with changeable tooling handle part families without full retooling.

Inspection Modes

Measurement Solutions for Every Production Scale

From a single prototype to continuous batch production, the right inspection approach depends on your volume, tolerance, and part variety.

01

Manual Hand Gauging

Simple air plugs, air rings, or electronic probes used directly by the operator at the machine. Fast go/no-go checks on individual features. Ideal for low-volume, high-mix production where flexibility matters more than cycle time. Minimal investment, immediate ROI.

Low VolumeHigh MixFast Setup
02

Manual Bench Inspection

Dedicated measuring benches with fixed or changeable tooling. The operator loads the part, presses a button, and all features are measured simultaneously. Results displayed on screen with clear OK/NOK indication. SPC data logged automatically. Best for medium-volume production with recurring part numbers.

Multi-FeatureSPC DataPart Families
03

Semi-Automatic Stations

Stations with pneumatic clamping, automated measurement cycle, and part sorting. The operator loads and unloads; everything between is automatic. Touch screen displays results, logs data, and signals the next machine for process correction. For high-volume production with tight cycle time requirements.

Why PFL Group for Mechanical Components

The same Swiss precision technology used in automotive and aerospace — scaled to fit your workshop needs and budget.

Scalable Solutions

Start with a simple air plug, scale to a multi-feature benchs. No minimum project size, we serve workshops and OEMs equally.

Quick-Change Tooling

Interchangeable air plugs, rings, and fixture plates for fast part changeover. One bench, multiple part numbers, reduce capital investment without sacrificing accuracy.

PRETEC Probe Compatibility

PRETEC probes are drop-in compatible with TESA and other major manufacturers. Switchable half/full bridge at customer site. You're never locked into a single supplier.

Masters & Calibration

We supply calibrated setting masters with every gauge. Full traceability to national standards. Re-calibration service available through our European service network.
