ALTHERMILL LAMINATED PEELABLE SHIMS

Product catalog summary
Overview: Althermill laminated peelable shims are designed for high-accuracy adjustments in mechanical assemblies. They consist of a stack of metal leaves glued together, allowing for easy peeling to achieve the desired thickness. This method offers precision without the need for machining or grinding solid shims, reducing costs and assembly time.
Advantages:
  • Time savings of over 50% compared to traditional methods.
  • Instantaneous and accurate sizing with easy peeling.
  • High accuracy and parallelism with basic thicknesses ranging from 0.025 mm to 0.2 mm.
  • Customizable to specific dimensions and specifications.
  • Economical with dual composition options for varied thicknesses.
  • Reduction in stock requirements.
Materials and Specifications: Available in various materials such as steel, stainless steel, aluminum, brass, and titanium. Standard dimensions are provided, with thickness options for each material. Shims can be produced in various shapes and compositions, including single and dual compositions for precise adjustments.
Technical Characteristics:
  • Accuracy depends on the basic thickness, with tolerances as low as ±0.002 mm for 0.025 mm thickness.
  • Parallelism is maintained at ≤0.01 mm for bonded materials.
  • Resistance to traction and temperature varies by material, with mild steel and stainless steel offering higher resistance.
Economic Benefits: Peelable shims allow for relaxed machining tolerances, reducing costs while maintaining high adjustment accuracy. They facilitate maintenance by enabling easy restoration of initial positions for gears and bearings.
Additional Features: Options for anti-friction coatings like Teflon or ceramic are available. The document notes that specifications may change without notice to improve product performance.

ALTHERMILL LAMINATED PEELABLE SHIMS-1

A LT H E R M I L L L A M I N AT E D P E E L A B L E S H I M S Althermill laminated peelable shims are shims for high accuracy adjustment. Consisting of a stack of basic metal leaves joined together by gluing over their whole surface, they form a laminated assembly of compact appearance consisting of a number of metal leaves. Each basic leaf may be peeled off very easily, until the exact thickness desired is obtained. The shim is therefore perfectly and easily adjusted in thickness to compensate accurately for play resulting from machining tolerances of any mechanical assembly. This ingenious process avoids the machining and grinding of solid shims while offering comparable or even greater accuracy. It also replaces stacks of foil thereby avoiding the problems of this type of shimming. In addition to the assembly time saved, the ease of use and reduction in costs, peelable shims enable stocks to be reduced by avoiding keeping solid shims in many thicknesses. Made perfectly to measure, to your drawing, dimensions and specifications, Jicey peelable shims are available in a wide range of materials (steel, stainless steel, aluminium, brass and titanium) to meet all your requirements. ADVANTAGES: - Saving time which may exceed 50% compared with grinding solid shims or machining special shims - Easy peeling, instantaneous correct sizing, no more wasted assembly time - Highly accurate assembly - Accuracy of parallelism - Thinness of basic thicknesses: from 0.025 mm to 0.2 mm - Perfectly ready made, to your dimensions and specifications - Economical process - Dual composition available (different thickness on each side). For example, a shim of thickness 1mm consisting of 8 leaves of 0.1mm and 4 leaves of 0.05mm - Reduction of stock

SHAPES AVAILABLE Althermill peelable shims can be produced in all geometrical shapes, by cutting out or machining, to your dimensions and specifications. In the majority of cases, the shims are flat and of constant thickness. It is nevertheless possible to produce compositions or special shapes or even to add other materials to one face. If the dimensions exceed those of the blocks, it is possible to produce shims in several parts, mechanically connected or otherwise. There are also peelable U shims in standard dimensions. ACCURACY Accuracy is obtained as a function of the basic thickness chosen...
