Walter launch crankshaft oil used in automobile industry new groove of the drill hole

Based in tubingen, walter for automobile manufacturers and suppliers all over the world to provide more efficient tools and solutions used in the manufacturing process.Adopting the new chip groove drill for oil hole drilling, chip removal effect is good, the knives’ service life is long, processing and high stability, and support for environmental protection and cost savings of trace oil mist lubrication (MQL).Figure 1 walter business development and Harald parts transportation manager PreußEr our drilling method can achieve a high level of crankshaft machining stability and efficiency, but also suitable for a large amount of machining process.In fact, all users to test with our new tool.(mouse hover amplifier, click view enlarge map) crankshaft oil hole drill itself faces a challenge.One of the most critical one of adjustment is the result of the drill hole depth and its consequences.Usually for more than 20 times the diameter or drilling depth.6 mm diameter hole is usually used in passenger car crankshaft, drilling depth of up to 120 mm, 150 mm.In extreme cases, the oil hole depth can be up to 30 times the size.Depending on the make and model of the workpiece can be used in casting alloy or steel.Usually tensile strength of 800 ~ 1200 nm ()).Passenger car is about 80% of the oil hole diameter is 4 ~ 8 mm, commercial vehicle crankshaft oil hole diameter is 5 ~ 6 mm for practice, 7 ~ 8 mm standard.Figure 2 DC173 6 mm diameter hole is usually used in passenger car crankshaft, drilling depth of up to 120 mm, 150 mm.In extreme cases, can reach 30 d oil hole depth.(mouse hover amplifier, click view enlarge map) challenge: deep hole clearance, especially steel crankshaft crankshaft, such as those of commercial vehicle the most prone to problem of drill hole depth: chip to be smooth and clean.If drill perforation artifacts, usually forming a long spiral chip.If the drilling depth of aperture of 5 times, chip removal is difficult.Walter business development and Harald parts transportation manager PreußEr said: & other;Before we start develop new drill clearance groove, must solve these problems.We have changed the drilling core part of the groove, in this way, will not form the crumbs, drilling now form the comma is the shape of particles.Short clastic won’t stuck between drilling and cutting tools, so the chip removal easier.Throughout the &;After adopting new groove, processing cutting tool tip small plane size is too large when the formation of the residual sludge is no longer a problem.Walter engineer research and development of new type slot also did some other improvement.Using today’s most processing idea and tool, when drilling deep hole process must interrupt to chip removal.& other;After using our new tools, we can be very deep holes, and can have been drilled in the end, because she had not drilling cuttings blockage, the efficiency is much higher than those in the past.Throughout the &;When using cast iron, the unique small plane minimize wear of cast iron workpiece processing conditions are different.Generally speaking, the iron processing easier than steel.But, especially grey cast iron can make the tool in the corner wear faster.In order to prevent this, walter developers to design the new oil hole drill, drilling for cast iron, formed a unique small plane.Figure 3 oil hole drilling position and process after using our new tool, we can be very deep holes, and can have been drilled in the end, because she had not drilling cuttings blockage, the efficiency is much higher than those in the past.Throughout the &;(mouse hover amplifier, click view enlarge map) Harald PreußEr especially proud of is the development of products made of trace oil mist lubrication (MQL) more efficient.Traces of oil mist lubrication refers to the process of cooling lubricant consumption per hour less than 20 ml.Do not use traditional emulsion or cooling oil wet processing, new product USES oil – air cooling and lubrication on the surface of a cutting tool and machining.The technological process of waste heat by cutting tools and drilling cuttings removal.In addition to the cooling fluid distribution and supply of reliable, safe clearance of trace oil mist lubrication is also very important.PreußEr said happily: & other;Our new groove type has the obvious advantage of chip removal.Throughout the &;Efficient economy, green environmental protection: trace oil mist lubrication widely used for various reasons of trace oil mist lubrication.On the one hand, the use of trace oil mist cooling fluid lubrication, has obvious financial benefits: trace oil mist lubrication and only 10 ~ 20 per hour cooling lubricants, rather than more than 500 litres.Therefore, the use of trace oil mist lubrication, almost all don’t need cooling fluid purchasing cost, storage cost and transportation cost.Cooling fluid and wet dust must be in accordance with the special waste disposal.This is expensive than fresh oil.On the contrary, dry crumbs can also be as renewable materials sales.Using trace oil mist lubrication, almost all do not use coolant disposal technology and subsequent expensive workpiece cleaning process.Figure 4, especially steel crankshaft crankshaft crankshaft, such as those of commercial vehicle the most prone to problem of drill hole depth: chip to be smooth and clean.(mouse hover amplifier, click view enlarge map) in addition, can reduce the dosage of the lubricant, clean environmental protection.These advantages have been producers to prove to the customer for many years.Oil mist does not lead to workplace accidents and machine tool operating personnel’s health hazards.Work with trace oil mist, however, does not apply for most processing concepts before, Harald PreußEr said: & other;If traditional processing concept using trace oil mist lubrication, average performance loss 20% ~ 30%.Throughout the &;Using walter new tool, however, things are quite different.& other;The guarantee of our new groove in the use of trace oil mist lubrication, the performance of the cutting tool and workpiece and the use of a large number of oil or other processing concepts of emulsion are exactly the same.Throughout the &;Through the global field test before listing, Harald PreußEr and his colleagues on its research and development of new products in the field test, and to plan the original plan.& other;We visited some of the biggest manufacturer in the world, they are in different conditions was tested on our tools.Throughout the &;Test, not changing the existing client machine tool conditions and peripheral processing equipment, and will use the new tool data obtained and compared with the previous tool data obtained.The result is clear: & other;We now tool service life is longer than previous solutions almost 50% ~ 100%.Throughout the &;80 ~ 110 meters of each knife allows the knives’ service life are common.Harald PreußEr, said walter new tool under the condition of agreement can be reached 160 ~ 200 meters, up to 300 meters.In addition, particularly high process stability.& other;The performance of the new cutter and other deep drilling.Throughout the &;Walter new oil hole drill has listed a few months.These bit as non-standard cutting tool sales, but the delivery time is very short.If the order quantity is less than 50 sets, walter can be delivered in four weeks, bulk order delivery time is the longest eight weeks.Harald PreußEr concluded: & other;On market as far as I know, there is no other drilling methods can achieve such a high level of crankshaft machining stability and efficiency, but also suitable for a large amount of machining process.In fact, all users to test with our new tool.Throughout the &;(the original title: used in automobile industry crankshaft oil drill walter new groove) (source: walter tool)
