The pitch of A and B gears of the drilling and tapping machine are fully matched with the pitch of A and B rotating shafts and the main shaft, which are vertically stable, accurate and highly precise. The drilling and tapping machine can move forward and backward when tapping the screw without any effort, and at the same time, it depends on the excellent processing items, which will not cause different threads in thickness. It can also tap perfect threads for thin plates, light metals, synthetic resins and other soft products.
The structure of square adjustable spindle box is the same as that of round type. If the working hole spacing is a straight or rectangular universal multi spindle box, the use method of drilling machine is the same as that of round type in order to avoid damage to the life of universal joint joint due to too large displacement. Try to match the working hole spacing coordinate. The gear box structure is designed to determine the boring position. The adjustment shall not exceed the specified angle by 15 degrees. If the spindle exceeds this limit, it is easy to wear or tear, and lubricating grease shall be added frequently during operation.
High precision tapping stroke is easy to adjust. The automatic reversing device can freely adjust tapping stroke. The shallow holes and low machined parts with holes of the drilling machine can also be easily adjusted. The double safety device can prevent the damage of the screw tap. The double safety clutch is specially designed for spindle rotation and up and down, and the advance and retreat of the cutter. The spindle can automatically stop, and the reverse and retreat of the cutter will not damage the cutter.
The fixed multi spindle drilling and tapping machine adopts the design scheme of single piece (workpiece) special machine. According to the reason of high processing frequency and large quantity of machined parts, the equipment of one machine is specially customized. Don't worry about size deviation in its work. In addition to using conventional products, special design can also be carried out according to the special requirements of customers.
