Kolmikoneistus

What Kolmikoneistus does

Kolmikoneistus Oy is a Rauma, Finland-based full-service machine shop that specializes in medium-heavy CNC and manual machining for industrial customers. Formally established in 2008 with operational roots extending to the 1970s, the company provides turning, milling, drilling, keyseating, deep hole boring, welding (MIG/MAG, TIG), heat treatment, surface finishing, assembly, and logistics services. It serves primarily Finnish industrial manufacturers and machine/equipment builders, delivering custom parts ranging from individual pieces to medium-sized production runs. The company operates from a single facility at Isometsäntie 9-11 in Rauma with 23-24 machining professionals and holds ISO 9001 quality management certification.

The business is organized around two integrated service lines. The general machine shop (Palvelukonepaja) handles standard CNC and manual work, while the Spare Parts Workshop (Varaosapaja) provides 24/7 emergency spare parts manufacturing, prototype services, and design support — including the ability to manufacture parts without customer drawings. The company's competitive positioning centers on accepting challenging and difficult projects that competitors decline, supported by a modern machine park that includes seven CNC lathes (including an 8-axis Doosan Puma turning center), three CNC machining centers, two deep hole boring machines, and complementary manual equipment, with capital concentrated during the 2022-2025 period.

Kolmikoneistus operates a quote-based, project-driven revenue model with no public pricing. Revenue is generated per order with substantial repeat business from established industrial customers. Go-to-market is sales-led and relationship-driven: customers contact the company directly via phone or email, with quote responses delivered within 24 hours and same-day delivery available for urgent orders. The company's geographic footprint is regional Nordic, and it maintains no external investors, parent company, or public listing — consistent with its profile as a founder/owner-operated Finnish private limited company.
