to give better flow of oil lubricant to the runner blocks so the maintenance of the machine is very low ,just need to clean from the dust at end of the day. Lubrication on travel axis is fully automated ,the 2 pump are separated.

we are using vacuum generator more reliable than vacuum pump,easy to replace not expensive and can run with a normal compressor,( if you cut more than 4 boards by day we suggest a screw compressor with 800 lt tank) The column are mounted on linear rail to ensure high precision and easy positioning under the blank. īlank on the machine this a very important how the blank is connect to the machine any movement of the blanks will result in imperfection during the cut so this aspect we designed a anchorage to the aluminum frame x axis with 6 vacuum holder pads and 6 pad ,to give the best to connect the blank without any movement. your question how many board can cut? let say shortboard ,1 pcs every 10 minutes top and around 20 minutes for the top, also depend how many lines of accuracy you put on shape 3d. so basically from 2nd generation this new machine 3rd generation is 30% faster. so basically we cut normally with a speed of 4,200 rpm this 350mm disc is a beast in term of cutting the wood stringer… looks like cutting a butter with a speed of 1500mm standard.

on this 3rd generation we install a 5.5 kw servo spindle able to arrive a speed of 12.000 rpm but lunch a disc of 350mm at that speed is too high in vibration ,the disc with abrasive max speed safe is 5.000 rpm when you use the speed travel of 9.000 mm per minute on the cutting lines. īut speed of machining is also related to the spindle speed. with the controller you can adjust this speed until 150%. usually you will cut the lines of deck or bottom with a x axis speed around 7.000 mm in normal mode if you need to make a board in very short time.you can reach the speed on axis travel feed of 9.000 mm per minute ,and still have a good finish quality. The frame we increased the stiffness of the machine, yes is pretty heavy to install and move, but the weight is the key of less vibration during operation cutting ,we changed from pneumatic z axis of the generation 2 ,to lower the weight of axis z with a normal counter weight balance, so with this system the z axis is pretty basic but we see is the most reliable ,is even faster can reach 5.000 mm per minute, and the axis x can reach even 10.000 mm per minute in all axis interpolated but this was done for testing the maximum speed( with this speed we cut a bottom in 5 minutes (24 lines) and top in 12 minutes 936 lines ). we tested on many board cuts ,and we designed the best product for high quantity production cutting with this 3rd generation. so basically this to explain difference in open loop and close loop,in industrial machine is preferred the close loop controller. the machine still run and loosing the correct position because the other 2 axis still running correctly( can happen in case the electric failure from the grid, there is a drop of voltage ). Īnother example with open loop if there is a mechanical problem on 1 axis or electronic problem from a servo drive. so normal cnc machine with servo motor with encoders incremental every time you finish a board or maybe 5 boards ,need to go home.to find again the zero position and the zero position is given from the limit switch,so basically the precision of this type is lower compare to absolute servo encoders, but the incremental servo encoders can be used with simple controller from normal computer like match 3. the absolute encoder what is ?…is a rotation controller mounted on the servo motor,knowing every time the real position ,even if the machine is off… and there is any manually movement on some axis, the absolute encoder will be exactly know the new position.when you turn on the machine. if there is a mismatch of position on 1 axis the controller stop the machine,this bring higher precision,because check every movement in a loop. What is meaning ?,all the axis X Y Z are connect in a loop. New data controller and servo motors with absolute encoders with close loop.

The new 2020 version of our production of cnc shaping machines, we did new improvement on this latest version.
