Marchant Dice router no thrust bearings?

[Shinobiwan]

Our designs have been through many years of development as our business has grown, we have automated many of our processes using our machines, to produce components for sale via eBay and worldofcnc. Any issue we would evaluate and redesign.

As the majority of our customers have business interests and therefore purchase a machine that is task related, we can adapt one of our many designs accordingly.

Press fit ballnut?
The ballnuts are not press fit….we use RSW ballnuts with an external V thread, the centre aluminium profile is bored and threaded to accept the RSW ballnut…
This range of machines are supplied to the world's leading probing manufacturers, in tests we achieve an accuracy of less than 0.010mm/300mm of the whole machine.

Later this year, all our Ballscrew driven machines will be fitted with thrust bearings this will align our product with our Class 5 preload Ballscrew driven machines and coincide with our 5 axis CNC being launched.

Finally
The floating end of a Ballscrew….
What happens if the Ballscrew spindle became warm? The spindle would need to expand along its length, hence the term floating.

If anyone would like to discuss in more detail please email [email protected] or call us 01805 628222 (phone line currently down however will be working again in the next day or so)

Many thanks

I'm sorry Kevin but you will win no supporters on here for your method of construction.

I bought a copy cat of one your machines that was actually better in some cases than yours but still inadequate. In this case at least it correctly captured the ballnut but still had similar issues with the ballscrew mounting that you have engineered into your designs.

Its sloppy, cheap and has serious question marks for the long term accuracy of the machine. You're basically knocking these out as simply as humanly possible to maximise profit. It wouldn't be so bad if you were charging a suitable amount but 4 series extrusions with the most basic and barebones mechanical make up possible? Not acceptable in my opinion.

You talk about selling to businesses? Your going to cost them money in the long run because they'll have to fix or replace what you should have done right to start with.

Please go back, redesign and come with something fit for purpose and stop inflating the capabilities of your machines. They're very very lightweight machines capable of only light cuts in soft materials. And your accuracy figures mean little. Is that the accuracy of a part, if so what material? Or is it more likely the accuracy of the machine with no load ie. cutting air?
