Tool industry in China and abroad about the gap between the developed countries, many people will think of the level of our technology and equipment behind. This course is a very important aspect, but we often overlook another equally important aspect, that is our concept for customer service and level, but also far behind. This may affect our key to development. This article is a Canadian tool distributors how to do everything possible to help users solve cutting problems, improve quality and efficiency of case processing. We hope that through this paper's case, can not speak of domestic still keen on some of the quality of service, blindly cut-Competition of the tool manufacturers and distributors, can be touched, and can lead to trade food for thought on this issue.
Sales competition, electronic commerce and new technologies, making it easier than ever buyers to buy better products at lower prices. But this reality, making the general life harder for vendors. The cutting tool vendors, for example, the face of tremendous price pressure, market, slow growth and modest profit, but also to show itself in the competitive advantage. For example, providing quality products, timely delivery and implementation of use of on-site technical services.
Just in Time Factory Supplies, Inc. (JIT) is a distributor of industrial products. As its name as metaphor, the company adopted the Strategic Approach is "Whenever, on time and timely delivery of products and services." ?
JIT offers a variety of CNC cutting tools, abrasives, metal band saw and a variety of tool material (carbide, ceramic, polycrystalline cubic boron nitride, polycrystalline diamond and the high-speed steel) made of special tools. The company deliberately creating a rewarding service in the field, it is difficult to machine materials to help users in the use of ceramic cutting tools, greatly promoted the improvement of labor productivity.
Sales Manager Don Burd said: "We closely follow the market demand to conduct business. With a hard ceramic cutting tool materials (HRC50 or more), many tool distributors are unable to provide complete information in this regard, because their experience is largely confined to hard Alloy tool. "
To help users solve the production problems
JIT success is due to both companies to understand the characteristics of their products, but also to understand the needs of users. For example, the company's technical sales representative contact Jim Brown on the regular production of stamping parts for the automotive industry group of the user factory. One is the Precision Resource Company, which is North America's leading supplier of precision blanking subsidiary (precision blanking is the use of precision metal stamping and cold stretch forming process high-volume manufacturing blank) Production Stamping The hardened steel mold and require a continuous thousands of times, sometimes to produce chipping. Precision Resource Company's shop foreman Steve Kraus said: "In this situation, we must quickly fix mold." Obviously, repair work and cost is the time to consider. For example, the chipping of the die height of cut 6.35mm, the use of a grinding, on the hardness of HRC61 ~ 63 of the M4 high speed steel punch, about 4 hours.
Brown that the grinding method used to repair the mold, stamping parts manufacturers of these too much time consuming. He wanted to be with advanced cutting tool to repair mold. To this end, proposed indexable milling cutter to repair the mold, the blade manufactured by Greenleaf WG-300-type ceramic whiskers (the material to alumina ceramic substrate, and with silicon carbide crystals to enhance, usually referred to as whiskers). Brown recommended cutter diameter of 25.4mm, with two RNGN-32T2A blade, cutting speed 152.4m/min, feed 355.6mm/min, cutters work fast. Shallow depth of cut as required (0.762mm), so negative rake angle of the circular double-sided indexable blade 16 times. But Brown added: "If the increased depth of cut 2.54mm, would reduce the number of translocation, the feed should be reduced." ?
Instead of grinding to a significant reduction in milling processing time. Foreman Kraus said: "Over the past by grinding takes 4 hours now with only 20 minutes milling ceramic knife. Processed out of the mold, its up to mirror finish. Nevertheless, the mold should be gently ground before use knife. " ?
Brown pointed out, set WG-300 ceramic blade cutter to bear the intermittent cutting work load, but the blade only to the normal flank wear. Long working hours unless otherwise does not produce chipping. ?
Although more expensive ceramic blades, each piece is 25 Canadian dollars (the same) but can be shifted 16 times, each cutting edge cost only 1.6 yuan, the cost to the company than the cemented carbide inserts used even cheaper. ?
Precision Resouce companies have tried repairing mold solid carbide end mills, but the repair of a mold should be consuming 60 yuan worth of three mills, a total of 180. The ceramic blade indexable milling cutter, only shifted once cost only 3 yuan, the effect is very significant. ?
JIT's another machine the user is a Reynolds-specific company that the steel industry and liquid handling products industry involves a series of refractory materials, including high-chromium white iron, chilled cast iron and nickel based alloys. Reynolds is part of a company's processing cycle cooling water tank on a semi-circular cap, which is a diameter of 127mm of steel castings, chromium 38%, 50% cobalt and small amounts of niobium (alloy composition according to the original literal?? Yi Zhu). Workpiece hardness HRC45 ~ 50, required direct milling out. One process in the casting of a mill to a radius of 63.5mm in the pockets, this part should be welded to the tube. Machining using a Xiang WG-300 ceramic blade diameter 127mm of indexable milling cutter, the cutter teeth have five knife. But Reynolols company found that, using a cutter knife and milling, but reduce the vibration of the benefit. ?
Factory owner Don Reynolos said: "carbide cutting tools simply can not process the parts. Who have tried high-quality coated carbide tool (cutting speed only 15.24m/min) to process, but were cut with a knife can not go first" .
Ceramic knife cut into the workpiece second arc: the first encounter casting shell knife, cutting more difficult; second knife is better, but still met the local casting shell, and so some of the impact load. Reynolols said: "The use of ceramic knife took only minutes to complete the procedures. Over the past year the company processed 500 600 such blocks, but recently received several thousand orders. Therefore, the improved process, shorten the processing time it is particularly important. "
The secret of success
JIT sold the company to use the knowledge of each tool are very familiar with. Therefore, users have the ability to make these recommendations. Sometimes, some small changes, you can determine success or failure of processing. Burd was this the example: the intermittent cutting conditions in the processing of acid-resistant nickel-based alloy parts surface, in the past 4 days time to process the user with four, but Burd with the help of ceramic cutting tools complete these parts only 5 hours. It is worth noting that the user has used the ceramic cutting tools such parts, but without success. Where the reasons? Burd pointed out that between success and failure, mainly methods are subtle differences. Preparation of first cutting edge. Users with a sharp blade over the past, it can not withstand impact loading. Replaced by T2A-type grinding method, will repair ground into the blade width of 0.152 ~ 0.203mm in the 20 ° negative back edge, with 0.0127mm of edge passivation. In addition, the use of cooling fluid past processing. This point, Burd particularly pointed out in the intermittent cutting conditions, cold and hot enough to blade fracture, or even damage the arbor, so can not use coolant. Burd also recommended that the original use of 243.84m/min the cutting speed increased to 366 ~ 457m/min, the fact that, in the use of cutting speed is 457m/min condition, no chipping tool, only the normal flank wear. 457mm cutting carried out to stop when the blade is red hot state, the blade intact. Shows the effectiveness of changes to these parameters. Processing each part took only 3 minutes. In the past, with carbide blade processing Zexu 45 minutes.
Ceramic cutting tools to work under high temperature conditions
Ceramic cutting tools at work to generate sufficient heat needed to make it close to the workpiece material to soften tool. This can reduce the cutting pressure is conducive to chip removal. An estimated 80% of the cutting heat will be passed to the chip. Burd noted that the cutting speed is too low, will Xianchu early chipping tendency. Therefore, a better approach is preferred to use higher cutting speed first, and then back again wear the appropriate adjustments. Conversely, a low cutting speed the start selection, tool chipping can not produce remedies. ?
Milling width also affects the chip temperature. For example, the cutter diameter is 25.4mm, milling width was 25.4mm, the cutting speed selected 121.92 ~ 152.4m/min. If the milling width of 12.7mm, the cutting speed to take 182.88 ~ 213.36m/min, this would maintain the chip's heat and blade pressure state. ?
Burd recommended tool to the user, the first to understand and hardness of the processed materials. General tool manufacturer cutting speed reference table, are based on the hardness of workpiece conditions developed. Burd noted that if the reference table on the recommended cutting speed is 137.16 ~ 152.4m/min, the corresponding depth of cut may be 0.635mm, 0.762mm or 1.27mm. Sometimes you want a change of use of feed rate, cutting depth or machine speed. This will often lead to cutting temperature. To illustrate this problem, Burd cited the following data: a cutter, work rotation as 2800rpm, cutting the depth of 0.76mm, the feed rate of 355.6mm, the chip load per tooth for the 0.05mm. If the depth of cut to 1.905mm, this time cutting temperature will increase, therefore, the speed dropped from 2800rpm 2400rpm. ?
Burd pointed out that any kind of tool, according to the terms of use to fine-tune the cutting parameters are essential. The ceramic cutting tools, this adjustment is even more necessary. Because the best use of ceramic tool area is only a "narrow window." In general, for carbide cutting tools, cutting speed and the recommended use of the table when a difference of ± 40% can still work properly. The allowable range ceramic tool is far smaller than it. However, once mastered the user's characteristics and patterns of ceramic cutting tools, its labor productivity can be greatly increased. ?
For example, JIT companies to help users solve one kind of rock crusher manganese steel parts processing, and achieved great success. Original use of carbide cutting tools milling, cutting speed only 30.49m/min, processing very difficult. After the switch to a diameter of 101.6mm of milling, cutting speed jumped to 457.2m/min, feeding capacity of 2032mm/min. Cutting parameters for improving the majority of machine operators was a little nervous. Therefore, tool distributors site service to let users know, only in high-speed conditions, the ceramic tool will be effective, it should be safe to use. Is important that sales staff in the field of direct services, will increase the confidence of the operator.
JIT services company through this two-pronged approach: on the one hand the difficulty of processing materials for users to find unique processing methods, at the same time provide users with effective on-site services, ultimately in the fierce market competition, not only survive, but also received a better development.
