The BO Machine Tools CBM 220 is a combined cylinder boring and engine blocks resurfacing machine for engine rebuilding operations.
It is supplied with a Ø 320 mm cutting plate that mounts a ½” insert in CBN or PCD depending on the material to be reconditioned.
The 3 boring bars cover a working range from Ø 30 to 170 mm and are supplied as optional equipment.
The BO Machine Tools CBM 220 is a combined cylinder boring and block resurfacing machine that concentrates the main engine reconditioning operations in a single machine.
In fact, the BO Machine Tools CBM 220 allows the operator to carry out cylinder boring and engine block refacing directly on the same machine.
This translates into a considerable saving of money and space in the workshop, as the CBM 220 allows you to do, with a single unit, what you would normally have to do with 2 separate machines, such as the boring machine for cylinders and the resurfacing machine for cylinder heads and engine blocks.
An additional benefit the CBM 220 provides is time savings.
Once the motor block is placed on the table, it does not need to be moved until the boring and resurfacing operations are complete.
The BO Machine Tools CBM 220 is also an extremely versatile and multifunctional machine that can also be used separately for boring or resurfacing operations only, depending on the operator’s needs.
The CBM 220 is supplied with a Ø 320 mm cutting plate for surface milling of the engine block.
The cutting plate is fitted with a CBN or PCD insert depending on the material to be ground, be it cast iron or aluminum.
The cylinder boring operation takes place through the use of boring bars that are supplied as optional accessories, according to the customer’s working needs.
The CBM 220 can be equipped with 3 boring bars covering a wide machining range of Ø 35÷170 mm.
The boring bars of the CBM 220 are:
The pre-setting system allows to set the boring diameter of the tool directly on board the machine.
Another important feature of the CBM 220 is the maximum customization during all the machining phases.
Equipped with the most advanced technical devices, it can count on the variable rotation speed of the boring bar with a range between 75÷850 RPM.
The variable speed of descent of the boring bar is 0÷175 mm/min while the variable feed speed of the table is 0÷460 mm/min.
All these adjustment possibilities offer the operator the widest possibility to customize the boring and resurfacing parameters.
The large table surface of 1340×370 mm and the considerable distance between the table and the head (1020 mm at its maximum extension) allow the CBM 220 to accommodate engine blocks of up to 1200 mm.
All the controls of this combined boring and resurfacing machine are placed on a convenient panel on the right side of the operator, thus allowing easy access during all working phases.
The control panel includes:
The BO Machine Tools CBM 220 is supplied with a wide range of accessories and tools as standard:
It can be further enriched with other accessories to extend the machining possibilities that the cylinder boring – engine block resurfacing machine already offers.
