Encoder and DRO save money in quality
assessment
An encoder and DRO offered the a turbo charger manufacturer immediate savings in both time and money in their quality assessment process of cast iron and aluminium samples.
A chance call was all that was required for Newall Measurement Systems to solve a problem that had plagued Bradford based BorgWarner Turbo Systems, a leading manufacturer of turbo chargers, for over 12 months The swift fitting of Newall's Magnasyn Encoder and SA100-R Digital Readout (DRO) offered the company immediate savings in both time and money in their quality assessment process

DRO has probe capabilities for lathes/millers
A digital readout system for manually operated lathe and milling machines has white-on-blue LCD display, geometric functions with probe capabilities and graphical dynamic tool position display.
Encoder system checks rotary, linear moves
A flexible, magnetically encoded tape scale for rotary and linear automation applications can be mounted quickly and easily on any fixed surfaces using the adhesive side of the tape.
BorgWarner's Quality Control Department was keen to find a more time and cost efficient way of inspecting cast iron and aluminium samples from their suppliers and had been looking for a three jaw chuck mounting for use on an existing digital rotary table that would fulfil this objective.
The inspection routine is important to BorgWarner's ISO 9001, QS 9000 processes and it was felt that a calibrated system offering greater speed and accuracy would benefit both the company and its end users.
When suppliers submit samples, the rotary table is used to mark out and assess the samples for BorgWarner's turbo compressors used in the commercial automotive sector.

Linear encoder ensures accurate cutting-off
An incremental linear encoder fitted to a billet cutting-off saw enables tighter tolerance cutting, so avoiding wastage in cutting expensive nickel alloys stock.
Linear encoders enliven vertical boring mills
Retrofitting linear encoders to the older vertical boring mills/vertical turning lathes reduces scrap and rework rates by improving machgining accuracy and repeatability.
Ian Porter, Quality Engineer at BorgWarner explains, "Our Quality Inspectors had been using vernier scales to take these readings, a process that was both time consuming and subject to a certain amount of inaccuracy.
However, every available digital rotary table that we had considered was not cost effective." Ian continues, "Newall's Brian Mosley was visiting the department on an unrelated matter when we described the problem to him and was immediately able to offer a practical solution.
Newall's flexible Magnasyn Tape Encoder was fitted around the circumference of the table to take the angular measurements of the outlet and inlet angles on the compressor housings, which in turn are displayed on one of Newall's SA100-R Digital Readouts (DROs)." Newall's Magnasyn encoder is specifically designed to address the problem of measuring uneven or circular machine movement by featuring a flexible magnetic rubber strip, which is sandwiched between a backing strip and a thin, protective cover strip made of stainless steel.
The ingenious design is not only extremely flexible, it can also withstand exposure to a range of aggressive elements - including dust, dirt and oil - and has received an IP67 approval rating.
The integrated reader head can travel at speeds of up to 4m/s and provides an accuracy level of +/-25micron and +/-20micron/m.
The compact, cost effective and easy-to-use SA100-R DRO is an ideal readout for use with the Magnasyn encoder.
It has a five year warranty, which is unrivalled by other manufacturers in the industry, is housed in an attractive, rugged die-cast chassis with a wipe-clean, tactile feedback front panel and offers outstanding panel clarity.
Standard features include scale factoring, linear compensation, axis resolution, head fail detection, standard inch/metric and reference functions, and automatic calibration.
Ian concludes, "Fitting of the tape was fast and simple and the total solution was so cost effective that we had no hesitation in proceeding immediately, with no other suppliers considered.
We are now able to achieve repeatable, fast and accurate readings with a calibrated system that ensures the entire assessment process is both quicker and easier.
Throughput and productivity have been dramatically increased and user error readings have been eliminated.".
