Motors from 4 to 25 hp even in UL version. High performance.
Planetario HEAD that is 100% tempered metal and geared driven not belt. The main disc and the satellites always run, allowing the machine to work very hard with high performance. The working pressure of the Planetario can be adjusted giving pressure on the front or on the backside. Giving more pressure in front the machine cuts faster and deeper. NO BELTS to break! Check what kind of Planetario they are using. The Planetario with BELT DRIVE doesn’t have the same performance of metal geared. Furthermore it is subjected to break during the work and needs a lot of time to repair. Attention: in many machines the main disc and the satellite don’t run together: if you block one satellite (one tools disc by hand) the main disc still runs. It means that using the machine for heavy duty work the machine doesn’t have performance at all. For many machines it is not possible to be used inclined the Planetario and as result can work only in one position. Therefore cannot cut fast and deep resulting in very poor performance.
The pressure is adjusted by “ELECTRONIC DEVICE”. Many machines do not have an ELECTRONIC DEVICE but have to adjust the pressure adding weight manually.
Bimack design the motor directly over the top of the planetario with three well balanced heads for perfect balance and highest grinding pressure available.
Steel frame painted with metallic varnish. Aluminium carter covering the Planetario. The metal covering protects the diamond tools and allows it to work very close to the wall. Many competitors machines have Plastic coverings. It breaks very easily, it doesn’t protect the diamond tools and doesn’t allow you to work close to the wall.
On the PANEL without opening the Inverter door it is possible to read the display to know what is happening with the machine. Check if this device is on the competitors machine.
Third front wheel that offers the following advantages:
- It makes for easy transportation.
- It allows to regulate the working pressure.
- It allows to inclination on the Planetario head.
- It is very useful when working on very uneven floors.
Check if the competitors machine has the third front wheel.
The planetario does not focus weight and pressure of the heads on the chassis to create a ‘floating head’, instead is a rigid system with very little flex (this design means the machine will ‘bounce’ a little over the floor until it is flat). ensures flattest floor possible and doesn’t make the floor ‘wavy’.
The tank is very important for working wet. When working dry the diamond doesn’t grip and skates on the surface of the concrete. It is also important for polishing marble, terrazzo and granite. Many competitor machines don’t have a tank. Check and see if it has a water tank.

Check the size of the tools. Many machine has the same working area but the tools are smaller. Smaller are the tools, less will be the performance.
This device avoids the door from being opened before “switching off” the “electric power”.
To avoid damage and injury while working in dangerous conditions.
Variable speed head that adjusts.
Vacuum ports for working dry and Free of Dust. Check if they have it.
Strong Perimetral neoprene splash guard. Check if they have.
If the machine is equipped with remote control please check the following points:
- It must be “active system” and not passive system. After an emergency if we push the START BOTTOM the machine does not start the operator has to follow the instructions.
- If the operator leaves the REMOTE CONTROL the machine stops working avoiding any injuries.
- Continue Control System.
It means:
- A intelligent Remote Control device allowed to check the presence of the operator according the safety rules
- If the operator leaves the device, the remote control stops the machine immediately.
- If the operator leaves the device it cannot be used from any other unauthorized operator to avoid any injuries.
- DEAD MAN SWITCH: all automatic movements are under control by “dead man safety device “in order to work free but in total safety.
satisfy what the SAFETY RULES (Art EN 60204-1 requires).
Adjustable position of the handle for a comfortable working position. It also can be reversed to allow the operator to drive the machine from front side and not only from the rear. Many machines cannot be used standing in the front but can be handled only from the rear.
This device automatically shuts off the machine if some electric problem happens avoiding any injuries. BIMACK uses the right and approved electrical components including oversized wire.
(Not a normal emergency button like on smaller machines). When this special emergency button is pushed the motor is immediately turned off and all the “moving parts “ (like tools) are immediately stopped avoiding any injuries.
The new start ( re-start ) after any stop cannot happen casually. Any start has to be active not passive. It means for example that if any one accidentally connects the electrical power, the machine doesn’t start again. To start again the operator has to follow all instructions correctly.
Simply clean and grease machine. Less maintenance required thanks to oversize burning and tempered steel gears.
Gears mean lower operating costs than competitors (belt changes are very expensive). Belts do not transfer torque as effectively as gears. Gears offers higher grinding torque.
Bimack machines allow it to work in domestic situation; tank motor and head are very compact and close together for work in small corridors.
