Model T807A/B Cylinder Boring Machine
Description
Model T807A Cylinder Boring Machine
T807A/T807B is mainly used for cylinder boring and repairing of motorcycles, automobile engines and small and medium-sized tractors.
Model T807A/B cylinder boring machine is mainly used for maintaining the cylinder of o tor cycle,etc. Place the cylinder to be bored under the base plate or on the plane of the base of machine after the center of the cylinder hole is determined, and the cylinder is fixed , the maintenance of boring can be carried out. The cylinders of the motorcycles with diameters Φ39-72mm and depths within 160mm can all be bored. If the suitable fixtures are fitted , other cylinder bodies with corresponding requirements can also be bored.

Working Principle and Operation Method
***Fixing of cylinder body:
Cylinder block fixation The installation and clamping of the cylinder block can be seen in the mounting and clamping assembly. When installing and clamping, keep a gap of 2-3mm between the upper cylinder packing ring and the bottom plate. After the axis of the cylinder hole is aligned, tighten the upper pressure screw to fix the cylinder.
***Cylinder hole axis determination
Before boring the cylinder, the rotation axis of the spindle of the machine tool must coincide with the axis of the boring cylinder to be repaired to ensure the repair quality.
***Use a specific micrometer
The micrometer is placed on the substrate surface using a specific micrometer. Turn the hand wheel to move the boring bar down, the cylindrical pin on the micrometer is inserted into the slot under the spindle, the contact head of the micrometer and the boring tool point does not coincide.
