Design of an Automatic woodworking machine

Programmable woodworking machine.

Our clients desire was to perform quickly two machining operations at both ends of a timber board. It was crucial to achieve relatively high productivity and high precision of machining.

The tasks of Nõmm Insenerid OÜ were divided into several stages:

  1. Sketching involved outlining the general working principles of the machine and making productivity calculations. Results were presented to the customer for approval.
  2. Main design process involved comprehensive engineering calculations and several stages of risk assessment. It was also our task to create a workflow description as an input for the electrical engineers and PLC programmers.
  3. Manufacturing and tuning of the machine was mostly task of our good partner. Nõmm Insenerid OÜ was involved at this stage as consultant.
  4. Finally we had to compile all the user documentation – user and service manuals. As woodworking machines involve many serious hazards this process had to be thorough.

As a result we can proudly declare that the machine has performed almost flawlessly for several years.

Design of  machinery for paper and woodworking industry

Machinery for metalworking industry

Many machine developments are based on serious engineering calculations. Some examples are: 

  • Linear plain bearings for horizontal hydraulic press; 
  • Calculation of gears and selection of couplings for a synchronized  rolling machine; 
  • Machine including crank shafts for operating the tool. Design is based on dynamic force analysis.

Examples of designed production equipment

  • Design of test rig for hydraulic jack
  • Design and manufacturing of a bending tool for electronics industry
  • Development of riveting tool for electronics industry
  • CNC portal milling machine design
  • Development and manufacturing of a electronic component test rig
  • Design of fine mechanics for optical test rig.
  •  Design of pallet crusher;
  • Pressure testing rig for aluminium die cast products.
  • Design of milling fixture for CNC milling machine
  • Design of a pendulum saw
  • Design of a feeder for woodworking machine
  • Design of a perforating machine.
  • Engineering of drive mechanism for ground drill 
  • Engineering of a slot milling machine

Fixtures and testing equipment

Desing of fixtures and testing equipment 

Design of production lines

Nõmm Insenerid OÜ has designed several production lines:

  • Curing and washing line for chemical plant;
  • Production line for steel painting;
  • Machinery and layout for limestone crushing and sorting factory;
  • Equipment for transporting and storage of round timber in a plywood factory. Project was interesting due to need of fitting one conveyor into very restricted space.

Design and manufacturing of washing equipment

Specialized washing machines designed by Nõmm Insenerid OÜ:

1. Washing line was developed a solution for washing and stacking wheeled containers.
This machine is able to grab the wheelie bin form a feeding conveyor and wash it according to the program chosen by operator.  A special low-pressure washing head was developed for this application. Next to the washing station is stacking machine.   It is capable of  placing containers with wheels into each other. How many containers is in one stack can be determined according to the needs of production. Both developed machines are capable of handling two and four wheel bins. This solution is well suited for recycling and waste management companies.

2. Automatic pressure washing machine for wide conveyor belt.
