The Best Way to Measure Deep-Bore/spherical Diameters

• 2 point (ovality) available from 3mm, 3 point available from 6mm
• 3-300mm range, 300-500mm XT500 System
• Guide sleeves available, 2 point to maintain centralisation, 3 point to protect the head/bore
• Allows for misalignment in bore
• XT, Ultima
• Ease of use for operator
• Interchangeable with standard heads
• Blind Bore option available

Each of these application heads can be fitted directly to our XT range of internal micrometers in seconds for fast, efficient use with incredibly accurate results.

Basic Spherical gauge lead-time 1-2 weeks including extensions 2000mm max.

Deep Hole Pneumatic Bore Gauging

Operated by a pneumatic actuator powered by a 3 bar compressed air supply - either from a compressor or a workshop air-line. The measurement data is collected by a capacitive probe fitted just behind, and in constant contact with the measuring head. This direct contact ensures high-quality transducer-type accuracy, even at great depths. Measurements are taken by pressing a footswitch connected to the airline and the data is then passed automatically via cable back down the bore to the digital readout at the operator end.

• Measures diameters from 50-310mm, up to 15m deep
• Spherical, Tungsten Carbide anvils
• 2 point and 3 point heads available
• Accuracy +/-0.005mm (subject to bore condition)
• Quick set-up time
• Easy to use
• Not adversely effected by temperature fluctuation
• Robust design
• Various readouts available

Pneumatic Actuator for Automatic Measurement of Ballscrew Nuts

Measurement of pitch diameter in ballscrew nuts on automatic machine. Match gauging of the ball circuit allows the optimum ball sizes to be selected for the required preload of the ballscrew bearing assembly.

The Solution:
The solution developed by Bowers' Specials Applications Team comprised an Actuating Unit and Ballscrew Head, fitted to customers' fully automatic machine.

Actuating Unit:
• Gauge body with constant measuring pressure and fast operation
• Pneumatic cylinder (3 Bar pressure required) to actuate the unit
• Supplied with Sylvac transducer probe and D302 multiplexer for output to PLC
• Internal workings enclosed in protective cover
• Mounting holes on rear of actuator body to allow fixing into customers assembly

Ballscrew Head:
• Precision 3 point measuring head with tungsten carbide ball contacts to locate in ball circuit and replicate final application using ball sizes matching the nominal ball size of the particular ballscrew assembly
• Various heads available customised to suit BCD, ball size, lead and direction (RH/LH)

• Automatic or semi-automatic measurement of internal features
• Can be used for threads, grooves, splines, etc
Potential Industries:
• Automotive - ballscrew manufacture/assembly
• Aerospace
• Machine Tools
• Bearing Manufacture
