Development of deep hole drilling machine:
Widely used in China's textile machinery, petroleum machinery, printing machinery, packaging machinery, medical equipment, aerospace, automobile tractors, rubber and plastic molds, as well as generators, machine tools, and other industries related to deep hole machining. Parts of the deep hole processing has been applied.
Basically, it can be divided into three categories:
(a) ordinary single-seat deep hole drilling machine.
Our predecessor in 1989, Dezhou Machine Tool Factory, in order to meet the needs of domestic processing, their own design and manufacture of the maximum drilling diameter of 20 millimeters, the maximum machining depth of 500, 1,000 millimeters of the Z2102-type deep hole drilling machine, which is China's first use of gun drilling method of drilling deep hole drilling machine in 1990 through the Ministry of the former Ministry of Machine Tools Industry ministerial level appraisal and rated as a national new product, filling the gaps in the domestic market, really put into use. In 1990, it passed the appraisal of the former Ministry of Machinery Industry and was rated as a national new product, filling the blank in China, and was really put into the market for production after half a year, and it was only after the user's batch test approval that it was gradually pushed to the market. The product has been controlled by ordinary relay Z2102, programmable controller control ZP2102, the development of electrical digital control system control and application of other advanced technology ZK2102, ZK2102A, which in order to improve the processing efficiency, to meet the requirements of mass production, and the development of a double spindle ZP2102X2, ZK2102X2 CNC deep hole drilling machine series and other specialized machines.
In the early 70s of last century, deep hole drilling machine in the world or the use of ordinary relay control. Such as the 70's ~ 80's into China's American ELDORADO company's MEGA50, Germany TBT company's T30-3-250, NAGEL company's B4-H30-C/L, Japan's Kanzaki Advanced Precision Manufacturing Institute of the DEG type of deep-hole drilling machines are relay control. 80's due to the emergence of numerical control technology gradually began to be applied to deep-hole drilling machines. In the late 80's, CNC technology gradually began to be applied to deep hole drilling machines, and this advanced technology was popularized especially after 90 years. Such as TBT company listed in the early 90's ML series of deep hole drilling machine in addition to the feed system from the mechanical stepless transmission to the use of AC servomotor driven ball screws, feed with slide guide using rolling linear guides in addition to the drilling rod box drive in order to ensure high-speed rotation, accuracy and smoothness of the exchange of pulleys and belts, and two-speed motor-driven graded transmission into stepless speed regulation of the frequency converter motor to the spindle drive, in order to ensure that small hole drilling deep hole drilling machine. For drilling small holes deep hole drilling machine and improve the level of quality of deep hole drilling machine to create favorable conditions. This can be seen from the following comparison of several major technical parameters, deep hole drilling machine development: (ML series is the recent, T30 series is the past)
Model Item ML200 ML250 T30-3-250 unit
Drilling range 1-axis 0.9~15 2~25 4~18 mm
2-axis 0.9~10 2~18 mm
2-axis 0.9~10 2~18 mm
3-axis 1~11 1~11 mm
4-axis 1~10 1~10 mm
Feed speed range 0~15000(stepless) 0~15000(stepless) 35~320(stepless) mm/min
Spindle power 2.4 7.5/2X4 KW
Rapid traverse speed 15000 15000 3500 mm/min
Spindle speed 1000~24000(stepless) 1000~9000(stepless) 1375~6100(stepless) r/min
① Drilling holes in a small direction, indicating that the technology content is high, the quality requirements are strict.
② spindle to multi-axis development, can process multiple workpieces at the same time, improve processing efficiency. ③ high spindle speed, the application of advanced electric spindle, smooth running, precision improvement. ④ feed speed range and large, so the deep hole drilling machine over the years due to the application of advanced technology, the level of rapid improvement.
(2) Specialized deep hole drilling machine.
In recent years, in order to process certain parts on the intersection or any angle, or with the centerline of the processing parts into a certain angle of the oblique holes, vertical holes or parallel holes, etc., the need for each country and special development and development of a variety of special deep hole drilling machine. For example, in order to process the oil holes on the crankshaft, connecting rods on the oblique oil holes, parallel holes and feed machinery feeding molds of a number of radial discharge holes and so on. For example, TBT produces BW200-KW deep hole drilling machine, which is especially suitable for machining oil holes in small and medium-sized crankshafts of motorcycles to light trucks, and BW250-KW deep hole drilling machine, which is especially suitable for oil holes in the crankshafts of medium-sized and large trucks, and both of them are equipped with four-axis CNC control of X, Y, Z, and W. The company has developed a series of special deep hole drilling machines to meet the needs of its customers. The company in order to customer needs, in a production line can be processed in a variety of different varieties of crankshaft oil holes, in 2000 designed and manufactured the first flexible crankshaft machining centers, can be processed from 2 to 12 cylinders of different crankshafts on all the oil holes. British MOLLART production and manufacturing company specifically for the processing of pellet extrusion molds and the development of six equal parts of six spindles at the same time processing the same workpiece on the six holes of the special deep hole drilling machine. The number of holes in the workpiece is up to 36000. All of them are controlled by numerical control system.
(C) three-coordinate CNC deep hole drilling machine.
With the increase in sales of home appliances market, the growth rate of plastic products accelerated, the plastic mold manufacturing industry is booming, deep hole drilling machine in order to meet the mold on the water holes, shooting pin holes and other holes in the hole system of deep hole processing. By the past a single coordinate axis of the deep hole drilling machine processing development to the need to process coordinates of the hole system of multi-hole processing and the development of three-coordinate CNC deep hole drilling machine has developed rapidly in recent years. 1995 my company in order to meet the Guangdong U.S. Air Conditioning Equipment Co., Ltd. developed China's first for the plastic mold on the multi-hole processing of the ZK2103-type three-coordinate CNC deep hole drilling machine in order to meet the needs of the mold manufacturing industry, the need to develop in addition to drilling deep holes. In order to meet the needs of the development of mold manufacturing industry, and developed in addition to drilling deep holes, but also for milling, tapping and other multi-functional ZXK2103 deep hole drilling and milling centers and three-seater CNC ZK2103A, ZKA2102 deep hole drilling machine. Such machine tools in the world of the relevant countries to develop very quickly, not only three-coordinate (three-axis CNC axis) deep hole drilling machine, and CNC axis has been developed to four-axis, five-axis, and some have been to six-axis fully automated six-axis CNC gun drilling machining centers or CNC milling and drilling centers, which have an automatic tool changer. A few years ago, the storage of tools in the tool magazine only 12 or 24, and automatic tool changer does not include long and thin gun drill, now not only the number of tools stored in the library to increase the number of gun drills and automatic replacement of the column, which is a great development. Such as: Germany IXI0N company's TLF1004 type four-axis CNC (X, Y, Z, B) deep hole drilling machine tool tool magazine storage 24, TBT company's T30/320-1050KT, FTS deep hole drilling center, roller tool magazine 24 (which 8 different diameters, each three pieces), their gun drills are not included in the automatic tool changing The Now the British MOLLART company's FMC series automatic six-axis CNC gun drilling machining centers, drilling diameter range: φ5 ~ φ50mm maximum drilling depth of 1350mm, in addition to drilling and milling, tapping function. When the rigid tapping M30 can not meet, you can also use standard milling cutter and spiral milling through the CNC interpolation function to process large threads, its automatic tool changer has 90 knives, including the length of 1500 mm gun drill automatic replacement, its unique feature is the special auxiliary support for this long drill, in the process of processing can be automatically in place and withdrawn, the machine tool also has a customized programming software GE . The machine also has a customized programming software GE . Programmable parameters: spindle feed rate, drilling depth, and monitoring of the machining process. In order to expand the range of machine tool processing specifications, some deep hole drilling machine both with gun drilling method of drilling deep holes, milling planes, rigid tapping function, but also with internal chip drilling (BTA method) drilling function, in order to drill large holes and increase the flexibility of the machine tool. Such as: Germany IX10N company's 1A5TL-1600-5 heavy-duty deep hole drilling and milling composite machining center, five-axis numerical control and its main technical parameters: drilling diameter range: φ3 ~ φ36 (65) mm, of which greater than φ35mm hole diameter can be used for drilling BTA method. A drilling depth of 1600mm, the maximum drilling depth of 2100mm, milling capacity of 250 (400) cm3 / min, spindle speed 300 (75) ~ 6000r / min, five-axis numerical control: W, X, Y, Z, B, A (-25 ° ~ +15 °), according to the "A" which W -drilling and milling unit moves horizontally; X-table moves laterally; Y-drilling and milling unit moves vertically; Z-column moves longitudinally; B-table rotates; A-drilling and milling unit swings. And then the German TBT company's MD30-KW deep hole drilling and milling machine, its main technical parameters: drilling range: φ4 ~ φ25mm, the maximum drilling depth of 1,000mm, milling capacity of 350cm3/min, twist drill drilling maximum φ30mm, tapping M24X3, the number of numerical control axes: X, Y, Z, W, B, A, there is the C-axis, the machine tool has a lot of flexibility, in addition to the processing of In addition to drilling deep holes perpendicular to the plane and on an inclined plane, it is also possible to drill oil holes in any position on the crankshaft using the "C" axis.
In recent years, in addition to the great development of deep hole drilling machine, deep hole drilling gun itself has also changed a lot. In the past, the gun drill specifications are generally φ2 ~ φ30mm or so, has now developed to φ0.9 ~ φ40mm or even to 50mm. Germany BOTEK company's gun drill specifications have been standardized to φ0.9 ~ φ50mm, in particular, which is greater than φ18mm of the drill can be used to machine chuck bit, it is a kind of non-resharpening drill, knife edge wear transposition, blade wear and replacement of blades or guide pads, will not hurt or waste the shank, shank, etc..
In summary, the modern use of gun drilling deep hole drilling machine tools and cutting tools and other machine tools, as the development of a rapid, to the CNC multi-axis, multi-functional development, the near future of environmentally friendly deep hole drilling machine will also appear one after another. To reduce or eliminate the impact of oil fumes on the human body.
