Euro-Tech Corp. says MyTec Hydraclamp expansion tools are the optimal connecting link between workpiece and machine. Now Mytec is introducing its new line of mechanical arbors and chucks with accuracy down to 0.0004" plus high expansion rates up to .010" or greater in a stainless steel construction. Mechanical arbors and chucks are excellent for workholding where high forces are incurred or auto load applications where high clearance is required.
Using special hydraulic expansion elements, a clamping system has been developed that far surpasses all traditional clamping in precision, clamping force and in transferred torque. State-of-the-art technology, precise construction and special materials are the basis for extraordinary performance for lathing, hobbing, grinding, testing and measuring.
A closed expansion system, which is absolutely impervious to dirt and chips, combined with high wear resistance, guarantees a long service life. If space permits, Hydra expansion elements from Mytec-Hydraclamp are generally equipped with an adjustment piston. This makes it possible to set expansion for fine clamping, particularly in the case of thin-walled workpieces, so deformation can be avoided. Tools have a hardness of 56 HRC with a center hardness of 64 HRC. An optional highly wear-resistant coating may be applied which will result in a surface hardness of 80 HRC.

- clearance
clearance
Space provided behind a tool’s land or relief to prevent rubbing and subsequent premature deterioration of the tool. See land; relief.
- grinding
grinding
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
- hardness
hardness
Hardness is a measure of the resistance of a material to surface indentation or abrasion. There is no absolute scale for hardness. In order to express hardness quantitatively, each type of test has its own scale, which defines hardness. Indentation hardness obtained through static methods is measured by Brinell, Rockwell, Vickers and Knoop tests. Hardness without indentation is measured by a dynamic method, known as the Scleroscope test.
- wear resistance
wear resistance
Ability of the tool to withstand stresses that cause it to wear during cutting; an attribute linked to alloy composition, base material, thermal conditions, type of tooling and operation and other variables.
