Welcome to our new website dedicated to hobby and machining enthusiasts who have a need for quality measurement and DRO systems. This site is still very much in development so please bear with us. We would be happy to hear from you concerning any items on the website, errors or omissions. Please e-mail us on: info@ems-i.co.uk.

Welcome to the hobby site of ems (International) Ltd. We are based in Kibworth, south Leicestershire and and have been supplying machine tool builders and distributors internationally for nearly 10-years and have experience in the machine tool industry much longer than that. We are now pleased to offer our experience, gained in an industrial world, to the home and hobby user where we strive to provide the best products, value for money and service.

Many of you will have trawled the Internet looking for the best deals and advice for your specific applications. We are UK based and pride ourselves in working closely with our customers of all sizes to ensure we offer the most suitable solutions at the best possible price. If you are unsure what is the best solution for your machine or would like to talk through various options please call us we will be happy to spend the time to go through all the options with you.

Things to consider:

When selecting the best package for installing on your machine you may be unsure about the relative merits of the differing DRO and scale technologies. As such, here is a brief overview of the relative merits of the differing options.

Optical Scales

Strengths

Weaknesses

These are the most common types of scales still fitted on the vast majority of machine tools today. They essentially have a glass grating inside and uses light to work.

  • Most common type available
  • Can be inexpensive for shorter lengths
  • Can be be highly accurate
  • Can have very high resolutions
  • Fixed standard lengths
  • Can not be 'Cut-to-Fit'
  • Not coolant proof

Enclosed Magnetic Scales

Strengths

Weaknesses

These are becoming much more popular as the technology gets better and better. These look like, and install, just like optical scales and in many cases can be a direct replacement.

  • Highly robust coolant proof (IP67)
  • Looks and install like glass scales
  • Cheaper than glass over 1100mm
  • Can be be highly accurate
  • Can have high resolutions
  • More expensive than 'budget' glass
  • Available only in standard lengths
  • Can not be 'Cut-to-Fit'

Spar Mounted Magnetic Scales

Strengths

Weaknesses

These are great on a large variety of machines due to the diversity of spars that are available. The scales can almost any length up to 60m or more! The reader-head is separate from the scale which allows greater flexibility any ease of service should it ever be necessary.

  • Highly robust coolant proof (IP67)
  • Can be 'cut-to-fit'
  • Broad range of accuracies & resolutions
  • Can be inexpensive
  • Easier to service
  • Can be ideal for smaller machines
  • Incremental, distance-codes and absolute options
  • Different fitting methodology to glass
  • Limited mounting kits available

Magnetic Tape Scales

Strengths

Weaknesses

Tape systems can be cut to any desired length and are very compact in size at just 10mm x 1.6mm thick. The tape is magnetically coded and is the same as used in the enclosed and spar mounted options, and is protected by a non-magnetic stainless steel protection cover.The reader-head is separate from the scale which allows greater flexibility any ease of service should it ever be necessary.

  • Highly robust coolant proof (IP67)
  • Can be 'cut-to-fit'
  • Broad range of accuracies & resolutions
  • Least expensive option
  • Easier to service
  • Can be ideal for smaller machines
  • Ideal for those on a tight budget
  • Incremental, distance-codes and absolute options
  • Requires more work to fit
  • Limited mounting kits available
  • Requires a good, oil free, mounting surface for the tape or a user made spar

LED DRO

Strengths

Weaknesses

Digital Readout displays come in two basic types: LED and LCD. The LED types are the most common and are the industry norm. In addition to the axes displays some have message displays and even tool/SDM displays (see EM200). When choosing an LED DRO ensure that the displays have a filter applied to ensure clear viewing. (Note: All ems-i LED DRO have a display filter). The LED's provide a fast display update and a broad viewing angle in a variety of ambient lighting conditions.

  • Most common available
  • Good viewing angle
  • Fast display update rate
  • Easy to use
  • Can be low cost
  • Limited information can be displayed. This means that whilst they are popular with skilled machinists they are not the best option for those with little or no machining knowledge.

LCD DRO

Strengths

Weaknesses

The LCD DRO's have a graphical screen, either mono or colour. These can display much more information and make programming of functions much easier. They also have detailed 'built-in' operational help, so little need for manuals. As they are more expensive they also tend to have more functionality and in the case of the EL600 and EL700, can store program's for future recall making them ideal for performing repeat jobs.

  • Latest technology
  • Easy to operate
  • See function settings at a glance
  • Built in Help
  • Comprehensive functionality
  • Ideal for Schools and colleges
  • Ideal for busy workshops with repeat work
  • Display updates not as quick as LED
  • Viewing can be difficult in direct sunlight
