Method of using mould processing cutting tools

Sept. 8, 2011 - PRLog -- Recently, through high-efficiency feed processing to achieve high-profile. Our company also meets market demand, launch of high feed sks series. From rough timber to cutting hardened steel and other hard materials, this product can be used for high-efficiency roughing. Newly developed replaceable carbide cutter + arbor (super tough bar) series is the tool to get the praise.

When processing tool overhang length increased, the knife had to understand the occurrence of vibration to reduce cutting conditions. In addition the blade is not only due to insufficient wear chipping and the vibration of the tool body will greatly reduce the edge of the anti-chipping. Especially in the absence of automated processing tool easily result in death crash and other major accidents.

Here, we introduce the corrective action about our company's new high-feed cutter body composition Shinkansen series.

Handle ultra-tough carbide rod series

1. Cutting

Blades long body overhang elongation, the vibration will occur, affecting the cutting conditions, especially the cutting speed can not lead to progress.

For example, sks-2020-130-s20 (diameter 20mm steel knife body), hanging length 190mm (l/d = 9.5), when processing s55c recommended cutting parameters: cutting depth of 0.3mm, cutting speed v = 80m/min , feed per tooth f = 0.6mm / blade, feed rate f = 1500mm/min. However, the carbide shank (super strong pole) msn-m10-140-s20 and high feed Shinkansen line with the interchangeable heads msh-2020-m10 used in combination, can achieve 1.9 times the cutting speed v = 150m/min, feed per tooth of 1.7 times of the original f = 1.0mm / blade, feed rate tripled f = 4800mm/min, and the vibration does not occur during processing, cutting smoothly.

In addition, when processing materials is s55c (201hb), using the blade type wdmw050316ztr of jc5040 material for processing. Cutting parameters: spindle speed n = 2390min-1, cutting speed v = 150m/min, feed per tooth f = 1.0mm / blade, feed rate f = 4800mm/min, axial depth of cut ar = 0.3mm, radial cut wide ad = 12mm. Use hair drier cooling for the comparison of usage life.

Blades under the conditions of high speed and high feed body, as much vibration, blades produce chipping, cutting to 25m long that can not be used. The "super-tough shot" series of processing under the same conditions to 525m (cutting time 109 minutes) also did not produce chipping phenomenon, received 21 times more lifetime.

When hanging a long step, the use of "super tough shot" series, is not only able to greatly speed progress in the high feed machining efficiency and tool life is also largely improved.

2. Processing cases

The examples of using ¢ 32mmsks replaceable carbide cutter + arbor (super strong rod) die casting process (heat-resistant tool steel), to improve processing efficiency and lifetime.

100mm long of the machine hanging clip-round blade cutter axial depth of cut ar = 1mm, feed rate f=2800mm/min, cutting amount of q=70cc/min, lifetime expectancy is 45 to 60 minutes. Carbide shank (super tough shots) compared to processing conditions can improve to ar=0.7mm, f=7000mm/min, q=122.5cc/min, processing efficiency progress by 1.75 times, life up to 190 minutes, progressed more than 3 times.
