Deep hole drilling machine is different from traditional deep hole processing. She mainly relies on specific drilling technology (such as gun drill, BTA drill, jet suction drill, etc.), and deep hole system with precise aspect ratio greater than 10 and precise shallow Special machines for drilling holes are collectively referred to as deep hole drilling machines. It represents advanced and efficient hole machining technology with high precision, high efficiency and high consistency.
They represent advanced and efficient hole machining technology. Through one pass, precision machining results can be obtained. The processed holes are accurate in position and dimensional accuracy. Straightness, high coaxiality, and high surface finish. Repeatability. It can easily process various forms of deep holes, and can also solve various special forms of deep holes, such as cross holes, inclined holes, blind holes and flat bottom blind holes. It can be used not only for processing deep holes with a large aspect ratio (up to 300 times), but also for machining shallow holes with a minimum drilling diameter of 0.7 mm.
The precision of deep hole drilling machine is adjusted - deep hole processing manufacturers come to tell you:
1. Adjusting the horn and anchor bolts is mainly to adjust the geometrical accuracy of the machine tool through the horn and anchor bolts. If necessary, the precision can be achieved by slightly changing the strips on the guide rails and the pre-tightening rollers.
2. Adjust the relative position between the manipulator and the spindle and the tool magazine, so that the machine tool can automatically run to the tool change position, manually complete the tool exchange action step by step, check whether the action of grasping the knife, loading the knife, pulling the knife, and rotating the exchange is accurate and stable. .
3. Adjust the relative position of the pallet and the exchange work surface. The machine tool is a double workbench or a multi-workbench. The relative position of the workbench pallet and the exchange workbench should be adjusted to ensure the smooth and reliable automatic exchange of the workbench.
The application range of deep hole drilling machine mainly has the following three aspects:
1. Parts that are difficult to machine on a general-purpose machine tool, or that require complex special fixtures on a general-purpose machine tool and require a long adjustment time to process;
2, need small batch multi-batch production (generally less than 100 pieces) parts, complex contours, high processing accuracy requirements or must be solved by digital methods of complex curves, curved mold parts, ready for multiple retrofit design Parts
3, need to carry out boring, milling, drilling, expansion, hinge, boring, tapping and other multi-process joint processing and one-time clamping can be completed parts, high-value precision parts.
