Diamond cutters include the most frequent types of cutting tools, basically because of the matrix and diamond tool made up of two parts, quite simple, many manufacturers work regarding how to improve Diamond cutter. Compressor of your very lots of applications, a compressor is frequently consisting of hundreds or 1000s of components, complex manufacturing process, technical requirements. In order to meet the production needs of the several parts, tooling and fixture is vital to reasonably designed with, to meet up with the needs of excellent, fast, and have to be improved additionally , on a number of diamond cutting tools and tooling design. Give three examples below:
Improvement, straight shank end milling cutter
2Cr13 chromium steel material from the packed Chamber, face width 12mm, dark 20mm, 200mm diameter ring groove. Initially using §? made 12 straight shank end mills for high-speed steel processing, deep 5mm, processing and adhesion of diamond chip is lower than 5 minutes on the milling cutters, deteriorating cutting, milling cutter edge collapse, tool change frequently in the process, efficiency is incredibly low, machining an engagement ring groove to 150 minutes. Use after Japan's Mitsubishi diamond carbide milling cutter, although performance is better than about the former, but chip chip-stacking capacity addititionally there is tank problem, when automatic processing with the processing center, edge collapse, and in some cases the tool appears broken.
Saw blades production employing the same cutter. Saw blade manufacturing process continues to be relatively backward, improved results over the years is tiny, no breakthroughs recently, after greater than a year of research and development by the Eastern industrial automation limited, manufacture of CNC gear drive devices, production pictures progress on saw blade technology, its device term for the saw blade automatic open CNC gear hobbing machine (CNC gear opened presses). Figure
Saw open effect of tooth-CNC turret punch press, high precision, small cuts better, equipment investment, high production efficiency, replace the automatic mechanical punching machine, ideal for large batch production line use. High degree of automation, saving labor and improve yield.
Second, improvement of milling flange diamond tools
Spiral tooth clutch one-way shape to spiral end face structure, torsional moment that passed itself off if it's above a clear value, generally known as safety clutch. Within the milling machine processing of the most extremely popular method a method of dividing head gear, calculated using the lead change, configure the proper implementation of change between head and table piece uniform rotation and uniform motion, thus processing the Archimedes curved surfaces. Tool selection Ñ„ 8~ Ñ„ 10 State milling knife, on knife Shi was required to Diamond milling knife cutting edged and workpiece axis phase cut, operation Shi tool fell to requirements depth Hou, min of handles insert min of Board hole within, shake min of handles 20 ring, in min of head rotating of while, table for longitudinal into to, makes workpiece for composite movement, are spiral slot; elevation tool, reverse turns min of head handles 20 ring, pull bolt, is constantly on the shake min of handles 20 ring, insert bolt, and repeat above steps processing another a spiral slot.
These costly processing methods, and can't be processed prior to drawings, stay the tooth root Cutter radius. Need manual repair file root part keeps its R0.5, low efficiency, accuracy just isn't guaranteed.
This phenomenon, mcdougal after careful analysis, and application of CAD-aided design, thought we would complete the main tooling and tooling improvements. Theoretical calculation of diamond cutter angles, shape, over, even offers begun to look at shape, necessary to guarantee is when to processing tool.
On reflection, I personally use existing universal tool and Cutter Grinder for machining of workplace, Ñ„ 22 domestic high-speed steel in spiral taper shank endmill with restructuring, front first grinding milling cutter, tyrannize tapered, single slope of 8 °. And then grinding angle, increases the chip capacity slot space, avoid more quick milling passes diamond chip stacking behavior occurs. Following your last operation was sharpening angle, angle is simply too small you can't start cutting pieces, it's the same simple make tool really advanced break. Processing because of this tool, extra point selecting 8 ° after ' quality 45# steel, try straight cutting effect is perfect, very smooth in the event the knife cuts deep 10MM.
Structure principle of three, tooling,
Its main part screw, right-handed helical teeth. Its working rule should be to turn hand wheel and drive the screw clockwise rotation, helical gears for counter clockwise (good stress analysis of helical gear, levorotation, axial force f up), resulted in a lead at the same time per week, simple structure and.
Tool after installation on milling machine spindle, vertical milling head turn clockwise to pull 7.5 °, level clamping tooling to milling machine working bench, what is the best parts fit. After trying have the effect is shocking, the entire spiral flange process took only 5 minutes to complete, more effective compared to original more times, tool our life is the first twice times, achieved once in every single 200 grinding machining technologically advanced, reuse tools around 10 times fully stick to the drawings and areas of the standards. Before that, spiral flange have try in three-axis machining vertical machining center with ball-end milling cutters (milling cutter machining helicoids interference), not just a longer processing time, and left the tool Nose Radius with the tooth root, subject to secondary processing.
