Grooved Roll FAQ
What is the difference that the alignment marker makes?
THE DIFFERENCE THAT SJOGREN’S ALIGNMENT MARKER MAKES:
A feature found only on Sjogren rollers, the alignment marker assures the operator that the wire’s centerline is maintained exactly from one roller to the next. The Sjogren alignment marker accounts for variations in bearing width and makes it easy for the operator to identify the correct way to mount replacement rollers to maintain tolerances.
The benefits include;
- Reduction in set-up time
- Vastly improves centerline alignment
- Improved productivity increases profits
How do you place the grooved roll with the orientation marker?
Review the following image for visual representation. you want the marker groove closest to the straightener base.
How do you set your grooved rolls on a straightener to eliminate curves?
Once you have mounted your rolls, you will adjust each knob slightly to slightly push the wire or rod down, and up respectively. Review the image below for a visual representation. the goal is to push just enough until the output is straight. This may take 2 or more planes, depending on your product.
What is the recommended maintenance schedule for grooved rolls?
The maintenance of your rolls is significantly influenced by their usage frequency, the surrounding environment, and the type of product being straightened. Below is a recommended maintenance schedule for vee and radius grooves, tailored for low, medium, high-carbon, and non-ferrous materials, based on 80-100 hours of machine operation.
Groove Type Material Replacement Frequency VEE Low Carbon 9 months VEE Medium Carbon 6 months
VEE High Carbon 3 months VEE Nonferrous 12-18 months Radius Low Carbon 12 months Radius Medium Carbon 9 months Radius High Carbon 6 months Radius Nonferrous 15-21 months What do these models cost?
Our grooved rolls are engineered with precision, and our products stand out for their durability and quality.
Each application is custom to your application but its important to consider that pricing is swayed by volume. We provide volume pricing on all of our grooved rolls, no matter the shape of the cut, allowing you to benefit from cost efficiencies when ordering in bulk.
Our production process is optimized to reduce costs when manufacturing more units in a single run, and we share these savings with you.
