CAD mock up of R8 Spindle and QTC tooling

Drawbar tension for R8 and MT3 collets to work safely with QTC tooling?

We have been asked on a number of occasions, and seen in a number of forums, the question of “How much tension should I put on my drawbar when I use  Emvio (or Tormach) repeatable Z tooling?” This question is a very common for those looking to make a pneumatically actuated drawbar using Belville washers. So what do you need to know about Drawbar Tension?

Emvio Engineering is now a reseller of all BCN3D products

It is with great pride that we bring to the UK market the products designed  BCN3D Technologies.

BCN3D Technologies started off as a project of Fundació CIM, which has more than 20 years of experience in Rapid Prototyping and knowledge transfer. The results have been impressive and that is why when we first came across the company, we were keen to collaborate with them

We will be keeping stock of as many of their products as our limited storage space allows but will be giving priority to the Sigma. As you may have seen in our earlier post, we were giddy with anticipation when the Sigma was released. In no time you will be able to browse our shop for all four of BCN3D printers:

BCN3D Sigma 3D printer

The BCN3D Sigma – The flag ship model that received the best quality award on 3Dhubs page for April

The BCN3D Lux – A SLA machine working with photoreactive resin allowing for fantastically fine layers and printing speed

BCN3D+ kit

The BCN3D Plus – A Prusa clone kit aimed at those wanting to build their own printers

BCN3DDR Delta Printer

The BCN3DR – Another kit but this time for a Delta printer

BCN3D Ignis laser cutter

The BCN3D Ignis – a premium 100W CO2 laser cutter with honeycomb bed and a 900×650 working area

3D printing obsolete machine parts

Being thrifty in the time of turmiol and economic difficulty is imperative to survive as a company. This has been the case with Oyzo manufacturers Giokarinis of Samos. Every summer we return to Samos for around two weeks to return to our roots and the directors of the company are close personal friends. It was over a glass of ouzo that we started discussing that their factory would have to reduce production in as they were having issues with sourcing spare parts. Bearing in mind that the machines are mature and well used, the original manufacturer had sold up and there are capital controls in place, it was almost impossible to source and import parts.

We took on the challenge to design and manufacture some of the more critical wear parts: the bottle neck grippers
