Who should choose the PLU-600x150 model?
The PLU-600x150 offers a longer bed than the base model, accommodating workpieces up to 610 mm. It's a great choice for workshops that handle a mix of small to medium-sized components.
Who should choose the PLU-800x150 model?
With a grinding length of 810 mm, the PLU-800x150 is suited for job shops and production facilities that require the flexibility to grind longer shafts, rollers, and hydraulic cylinders.
Who should choose the PLU-1000x150 model?
The PLU-1000x150 is a heavy-duty machine for grinding long components up to 1010 mm. It is perfect for manufacturing and repair of long shafts and other large cylindrical parts.
Who should choose the PLU-1250x150 model?
As the largest model in the series, the PLU-1250x150 is designed for heavy industrial applications involving very long workpieces up to 1260 mm. It offers the maximum capacity for the most demanding jobs.
What is the main difference between the PLU-500 and PLU-800 models?
The primary difference is the 'Distance Between Centers,' which dictates the maximum length of the workpiece. The PLU-500 accommodates up to 510 mm, while the PLU-800 can handle longer components up to 810 mm. The PLU-800 is also a heavier machine, providing more stability.
How does the PLU-1000 compare to the PLU-1250?
Both are large-capacity machines. The PLU-1250 has a longer bed, allowing for workpieces up to 1260 mm compared to 1010 mm for the PLU-1000. The PLU-1250 is also significantly heavier (3680 Kgs vs 2800 Kgs), offering maximum rigidity for precision grinding of very long parts.
Is there a significant price difference between the models?
Yes, the price increases with the size and capacity of the machine. The PLU-500x150 is the most affordable, while the PLU-1250x150 is the premium model. The price reflects the increased material, construction, and capacity of the larger machines.
