Lohmeyer NCB 3010S CNC drilling machine for furniture production

One of the machines that caught my eye at Last year's BIFE SIM fair was a Lohmeyer NCB 3010S CNC drill that could drill many holes in a very short time. For example, in the demonstration I saw it drilled more than 70 holes in a minute and a half. I saw it at work in the Danibrum and you can see it in the video at the end of the article. But until then, I want to tell you a little bit about drilling in wood and wood by-products, the advantages of using a CNC but also the story of the Lohmeyer brand.

Cutting of wood and wood by-products

You can't make furniture, doors, windows, stairs and other such items out of solid wood or wood derived boards without joining at least 2 elements. To make the joints the elements have to be machined to fit together as closely as possible. In the past, all kinds of traditional joints such as swallowtail, cep and burr or nut and stink.

Coming more to our times, things started to simplify and more and more were used dowel joints or screws. The wood or derived boards had to be drilled. The mass production of furniture led to increasingly sophisticated machines and tools to make the holes quickly and well.

Drilling wood using machines does not, unlike drilling metal, require cooling the tool going into the wood. The wood is much softer and the friction that occurs between the drill and the wood does not lead to overheating. The drill does not lose its qualities and the wood does not ignite.

In order to have a quality hole, the entrance and exit of the hole must be clean, with no splinters or torn wood. Also, the wood or panel being drilled must not burn locally (blacken). The tools used for drilling should therefore be sharp and the speed of rotation chosen according to the hardness of the material and the depth of the hole.

The use of blunt tools or the wrong working parameters can result in material pulling out of the hole, jeopardizing the strength of the joint.

Advantages of using a CNC drilling machine in series production

Furniture production involves a lot of drilling operations. Done one at a time means a lot of time and low productivity. Using a CNC can greatly reduce drilling time.

But the biggest advantage of using CNC is the precision with which the holes are drilled. Once the dimensions are set and put into the CNC program, the holes will all be drilled exactly as programmed, with maximum precision. The parts will fit together perfectly, with the joints being made without any play or forcing.

Another advantage of CNCs is the possibility to drill holes with different profiles and to combine drilling with threading, reducing working time. A CNC with a tool magazine will allow the use of drills, thread mills or milling cutters and their easy replacement and a well-chosen program will shorten the working time significantly while increasing the quality of the joints.

The Lohmeyer story

But back to the Lohmayer CNC. Searching for information about it, I found out that the Lohmeyer brand is actually the surname of the German husband and wife team Tanja and Peter. They have worked a lifetime in the woodworking industry, Tanja being an architect with a solid carpentry background and Peter a woodworking engineer. Peter worked as sales manager in two large woodworking machinery companies. His sales experience gave him a good understanding of what people who needed woodworking machinery wanted.

Thus was born the idea of having our own woodworking machinery company. The machines produced here would be simple to use and solve as many problems as possible simultaneously. In addition, the company would be customer-oriented with a simple and decentralized organization.

He built the company with his wife, their experience in the wood industry being of great help. The Lohmeyer brand is now well known and respected in Germany and many other countries where wood is processed and derived products. In the Danibrum portfolio you will also find other Lohmeyer machines for various types of machining.

CNC Lohmeyer 3010 S

The CNC Lohmeyer 3010 S is a robust and easy to use CNC drilling CNC. It is designed in such a way that it can be connected to furniture design and manufacturing software. This makes transmitting information to the computer easy and you won't have to do any extra work.

Such a machine is, in my opinion, very useful for those who make furniture from chipboard and MDF. Joining panels requires many holes, both vertically and horizontally (on the edges), and the CNC can do them all at the same time. This means big time savings and perfect joints.
