Custom washer manufacturing by AREM-CNC
Custom washers

Precision CNC washer manufacturing

Standard and custom washers manufactured by CNC machining, from technical drawings or according to DIN, ASTM and ISO standards, with certified materials, dimensional control and full traceability.

AREM-CNC production

Machined washers for critical industrial fastening systems

At AREM-CNC, we manufacture custom machined washers designed to guarantee fit, strength and dimensional stability in demanding industrial applications.

We develop made-to-measure washers by combining geometries, thicknesses, materials and surface treatments to achieve the right technical performance for each project.

Types of washers manufactured by machining

We manufacture standard and custom washers with geometries, thicknesses, diameters, materials and finishes adapted to each industrial application.

01

Flat washers

Support washers for load distribution, mechanical adjustment and surface protection.

02

Spring lock

Elastic solutions for fastenings exposed to vibration or demanding assembly conditions.

03

Safety washers

Washers designed to improve locking, stability and reliability of the assembly.

04

Spherical washers

Parts for angular compensation, special supports and assemblies where alignment is critical.

05

Conical washers

Technical washers for applications with axial load, pressure or specific seating requirements.

06

Belleville washers

Elastic washers for systems requiring load absorption or controlled mechanical behaviour.

07

Square washers

Designed for structures, anchors and assemblies requiring a larger bearing surface.

08

Made to drawing

Custom manufacturing according to technical drawings, physical samples or special customer requirements.

Industrial applications

Designed for environments where fit cannot fail

AREM-CNC machined washers are used in sectors where safety, strength and dimensional accuracy are critical factors for assembly performance.
