The best cutting methods for difficult-to-machine materials are constantly evolving, new and difficult-to-machine materials are constantly emerging, and the processing of new materials has always plagued engineers and technicians. Recently, new machining centers, cutting tools, jigs, and CNC cutting technologies have developed rapidly. In addition to cutting, CNC grinding and CNC machining have also achieved unprecedented development. The selection of processing technology for difficult-to-machine materials has been Great expansion. 
Of course, the collection of information about the processing of difficult-to-machine materials and the in-depth understanding of the technology are not satisfactory. Because of this, and the continuous emergence of difficult-to-machine materials, people always feel that processing technology is not enough. 
For example, the above-mentioned turning processing is converted from continuous cutting to intermittent cutting, which is beneficial to prolong the life of the tool, and the use of the new coated cemented carbide tool further improves the cutting technology level of the difficult-to-machine material. In the machining of difficult-to-machine materials, special attention should be paid to the stability of the tool life. Not only the workpiece material should be properly matched with the tool performance, but also the requirements for machining size, surface roughness and shape accuracy are extremely strict. Therefore, it should not only be special. Attention should be paid to the selection of tools, the clamping of the workpiece and other related technologies.
In the future, the processing of difficult-to-machine material parts will adopt computer-controlled production methods such as CAD/CAM and CNC cutting. Therefore, the improvement of the tool management system such as database construction, tool design and production is extremely important. In the machining of difficult-to-machine materials, the data on cutting conditions, such as the applicable tools, fixtures, process schedules, tool trajectories, etc., should be accumulated as basic data, so that the production methods of parts can be developed in the direction of IT-based. In this way, the cutting technology of difficult-to-machine materials can enter a new stage faster.
Transfer Pipet
Practical disposable transfer pipettes, made from natural low density polyethylene (LDPE). The transfer pipet is simple and safe to use with a long shelf life; no issues with broken glass, cracked or loose bulbs. Additional advantage is that with the single piece design lager amount can be transferred by allowing fluids in the bulb. These plastic transfer pipettes are ideal for transferring small amounts of fluids for microscopy sample preparations or to prepare mixtures or staining solutions. The extra fine tip enables transferring minute amount of fluids. These cost-efficient plastic transfer pipettes are disposable and intended for one-time use. Ideal for educational and research environments. Can be used for fluids up to 70°C, please take care to protect the fingers squeezing the bulb. Available in six sizes/styles: 0.5ml, 1ml, 2ml, 3ml, 5ml, 10ml.
