Reaming and reamer chuck

The reamer is a general-purpose tool for machining high-precision holes. It guarantees the surface roughness and dimensional accuracy of the machined surface by micro-cutting and squeezing. Reaming on a common machine tool, whether with a front guide or front belt, rear guide Or a reamer without a guide, the reamer should be mounted floating. This is because the process system is difficult to ensure that the center line of the reamer and the center line of the preformed hole of the workpiece are coaxial when reaming. Often, the rigidly connected reamer generates a wobble during rotary cutting, causing the hole to expand in size, the shape error is excessive, and the surface roughness value is increased. Therefore, it is necessary to change the rigid drive to a floating drive, and use a special chuck to hold the reamer. There are many forms of special chucks, which should abide by common requirements and basic principles.

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.
