Problems solved by technology

However, due to the limitation of its own structure and function, ordinary drilling machine (machine) cannot realize deep hole processing
[0003] The existing commercially available CNC gun drilling machines have the following four main defects: one is that the workpiece is clamped by a hydraulic device, and it is quite inconvenient to adjust the clamping position according to the length of the workpiece; The volume is quite large, which increases the manufacturing cost of the machine tool; the third is that the cutting fluid cannot be recycled immediately, and often needs to be replaced, and the overall cost of cutting processing is high; the fourth is that when the tool is overloaded due to jamming, the tool is often damaged, and in severe cases, the whole machine is damaged. machine
It does not overcome the above four major defects, nor can it do deep hole processing

Description

technical field [0001] The invention relates to a numerically controlled gun drilling machine, in particular to a numerically controlled high-efficiency deep hole gun drilling machine. Background technique [0002] At present, in the machinery manufacturing industry, it is very common that the aperture of the drilled hole is getting smaller and smaller, and the drilled hole is getting longer and longer. Therefore, deep hole processing technology has been widely used. For example, the drilling of mold runners and thimbles in the mold industry; the drilling of steering gear input (output) shafts, racks, gearboxes, and gear shafts in auto parts; crankshafts, connecting rods, camshafts, and cylinders in engines. , Drilling holes on cylinder heads and pistons; deep hole processing in instrumentation, electric power, and petrochemical industries, etc. However, ordinary drilling machines (machines) cannot realize deep hole processing due to their own structure and function limita...
