The hole with a long diameter ratio (L/D) greater than 5 is called a deep hole. The advantage of deep hole drilling is that the machining of the precision hole is completed by one infeed, so the drilling efficiency is superior, and the material cost of processing high density and high strength is processed. low. Precise guidance during drilling and subsequent self-guided, so the machining process is stable, the aperture error is small, and the aperture accuracy can reach IT7-IT9. The position error of the hole, such as the jump of the hole, is small. If the workpiece is rotated, the workpiece reversal error is minimized. The surface roughness of the machined surface is low, which can reach Ra0.8~3.2. Less burrs. The maximum drilling depth is no more than 100 times the diameter of the machined hole.
TBT is an efficient and precise deep hole specialist. TBT has three methods for machining deep holes: single-blade gun drilling method - the external chip removal method means that the chips are discharged from the V-shaped waste; the BTA method - the internal chip removal method means that the chips are discharged from the tool center, including the nesting; Method - The internal chip removal method means that the chips are discharged from the center of the tool. Suitable processing materials are cast aluminum, aluminum alloy, non-ferrous metal, cast iron, structural steel and easy-cut steel, quenched and tempered steel, carburized steel, nitrided steel, ferritic and austenitic steel, stainless steel, titanium steel, Nickel steel. The electrical control system used is: Siemens S7-300/S7-500 PLC programmable controller. OP17 operation panel--with keyboard, 8-line 40-byte LCD display, which can display operation prompts and troubleshooting information. Multi-axis CNC Siemens 840D CNC system can process the following process parameters: cutting fluid pressure, Spindle drilling power, spindle feed power, feed force, cutting amount, etc. are monitored.
Comparison of BW series deep hole drilling center and conventional machining center
The BW series combines discrete processes such as drilling, reaming, milling, tapping, and deep drilling to achieve a multi-process centralized machining on a single machine. The ability to change process parameters and cutting amounts to adapt to changes in production objects through programming is strong. The advantages of process concentration are: more processing content, fewer processes, less equipment, correspondingly reducing the number of operators and production area, reducing the number of workpiece clamping, shortening the process flow, shortening the auxiliary time, simplifying production organization and production planning, The production preparation workload is small, the most favorable cutting amount can be selected, and the adaptability when changing the production object is strong, because more surfaces can be processed in one clamping and it is beneficial to ensure the mutual position between the surfaces. Heavy-duty parts concentrate on processing as many surfaces as possible in one process, which can greatly reduce the amount of labor required to load and unload workpieces and transport. The BW series of machine tools are suitable for the above conditions of use in the mold manufacturing industry. Although the initial investment in process equipment is slightly larger, adjustment and maintenance costs are small. It is worthwhile to measure from the benefits of long-term use.
