Lohmeyer NCB 3010S CNC drilling machine for furniture production

One of the machines that caught my attention 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 bit about drilling wood and wood derivatives, the advantages of using a CNC and the Lohmeyer brand story.

Sawing of wood and wood products

You can't make furniture, doors, windows, staircases and other such objects out of solid wood or wood-derived boards without joining at least 2 elements. To make the joints the elements must be machined to fit together as closely as possible. In the past all kinds of traditional joints were used like swallowtail, log and hollow or nut and feder.

Coming more to our times things began to simplify and more and more use was made of dowel joints or screws. For them the wood or derived boards had to be drilled. The mass production of furniture led to increasingly sophisticated machines and tools to drill holes quickly and well.

Drilling wood with machines does not require, unlike drilling metal, the cooling of the tool entering 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.

To have a quality drill the entrance and exit of the hole must be clean, without splinters or wood splinters. Also, the wood or panel being drilled must not burn locally (blacken). The tools used for drilling must therefore be well sharpened and the speed of rotation chosen according to the hardness of the material and the depth of the hole.

The use of unsharp tools or the wrong working parameters can lead to material pulling out of the hole, endangering the strength of the joint.

Advantages of using a CNC drilling machine in series production

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

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's work program, the holes will all be made exactly as programmed, with maximum precision. The parts will fit together perfectly, with joints being made without play or forcing.

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

The Lohmeyer story

But back to the Lohmayer CNC. While looking for information about it, I found out that the Lohmeyer brand is actually the family name of Tanja and Peter from Germany. They have worked in woodworking all their lives, Tanja being an architect with a strong background in carpentry and Peter a woodworking engineer. Peter worked as a sales manager in two large woodworking machinery companies. His sales experience helped him to understand very well what people who needed woodworking machinery wanted.

That's how the idea of owning his own woodworking machinery company was born. The machines produced here were to be simple to use and solve as many problems as possible at the same time. In addition, the company was to be customer-oriented, with a simple and decentralised organisation.

He and his wife set up the company, their experience in the wood industry being of great help. Now the Lohmeyer brand is known and respected both in Germany and in 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 processing.

CNC Lohmeyer 3010 S

The Lohmeyer 3010 S CNC is a solid and easy to use CNC drill. It is so designed that it can be connected to furniture design and manufacturing software. This makes it easy to transmit information to the computer and you won't have to do extra work.

Such a machine is, in my opinion, very useful for those who make furniture out of 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 significant time savings and perfect joints.
