Laser Cut Electrical Steel Grade Laminations for Motors

Up to 900mm o/d (+/-0.10mm) x 800mm i/d (+/-0.08mm).

Tolerance on teeth and slots +/-0.10m.

Thickness Tolerance

Thickness tolerance in accordance with BS EN 10051:2010

Flatness Tolerance

Flatness tolerance in accordance with BS EN 10029:1991.

Laser Tolerances for Lengths and Widths

Rectangular

For rectangular laser cut steel plates, where length L, is defined as the greater of the two dimensions, tolerances on length and width shall be as given in table 1.

Non-rectangular

For non-rectangular laser cut steel plates, because of the difficulty in defining length and width for non-standard shapes, tolerances will be as given in Table 1, where length L shall be assumed to be the maximum dimension of the part in question.

Circles and Rings

For laser cut steel circles and rings, length L will be understood to be the outside diameter of the part in question and tolerances will be as given in Table 1.

State-of-the-art

We continue to invest in the latest cutting technology to provide our customers with the highest quality profile cut parts.

24 hour cutting

Our 6 laser machines are cutting around the clock to ensure we’re always able to provide short lead-times.

Precision parts

We know how important accuracy is for our clients. Our lasers provide the very best in precision cut parts.

We’ve been in the profiling business for over 35 years and today we’re considered one of the largest and most diverse specialist cutting companies in the UK. We continue to invest in the latest cutting and automation technology to provide our customers with the highest quality cut parts in the shortest possible lead time.Contact us with your requirements today and join over 5000 customers who choose us for their profiling needs.
If you have drawings to send, we’re happy to accept DXF, DWG or dimensioned PDF files. By sending the above file types, we can easily process your order with our quoting system which vastly improves the speed at which we can get you a price.
For simple profiles such as squares, rectangles and cirlces with simple holes or slots we can work without a drawing.Alternatively, we also have an in-house CAD drawing team who can draw up your profile for you.As well as this, we also have a Laser QC scanner which enables us to scan and convert a physical object to a readable CAD file.
