Stone Medical

Stone Medical is a DBA of Gaskin MFG, which offers computer numerical control (CNC) machining for complex medical devices.

We created our state-of-the-art facility with organisation, cleanliness and quality in mind.

With a quality management system that sustains a dual certification for both the International Organisation of Standardisation (ISO) 9001: 2015 and ISO 13485: 2016, we are confident in our ability to produce high-grade medical instruments, components and devices.

We manufacture all our products at our facility in Plainville, Massachusetts.

Swiss CNC machining for complex medical devices

Stone Medical is a Swiss CNC screw machine shop that specialises in medical device manufacturing.

Using multi-axis screw machines, we produce high quantity, high complexity products used throughout the medical industry, including bone screws, bone screw extractors, blood transfusion pump shafts, bone anchors and a multitude of other surgical devices.

Our Swiss CNC screw machines can produce the parts, making them more advanced than conventional lathes. In a Swiss-type screw machine, the headstock contains a component (collet) that clamps the material. The material is then fed through a customised guide bushing, usually made of carbide, loose enough so the matter can slide smoothly through it, but tight enough to keep the material from flexing away from the cutting tool.

The guide bushing is what separates Swiss CNC screw machines from conventional lathes. It allows the appliances to maintain very tight tolerances concerning part diameter, even over long lengths, a +/- .0001 in precision. Swiss CNC screw machines are vital to creating the various categories of parts required by today’s medical device industry.

Stone Medical offers quality, accurate machining of stainless and cold-rolled steels, brass, plastics, aluminium, copper, nickel alloys and precious metals. Our most used material is 303 stainless steel.

High-quality components for the medical device industry

Our engineers have extensive experience in the design, development, manufacture and testing of medical device parts.

We provide excellence in our customer service, our customers are active participants in the entire process, ensuring that we meet their specific needs and deliver a product that exceeds their expectations.

With a fully approved quality management system, we have successfully set the framework to focus on the contract manufacturing of a wide range of medical and surgical devices, including crucial devices used by the medical community and for surgical environments.

Along with our motivation to improve our quality management systems, we make widespread investments to improve our overall quality, technology and experience.

Swiss CNC screw machines for precision and tight tolerances

Stone Medical’s Swiss CNC screw machines are the best option for the manufacture of small medical device parts.

Swiss CNC machining differs from traditional cam screw machines, which develop component shapes by creating a form tool of the part feature inside the device.

Swiss machines generate the required component of the part by moving the material and the tool simultaneously, making for a vastly more efficient process, while maintaining accuracy and quality.

We provide a wide range of medical devices and instruments, as well as custom parts designed with your specifications, including:

Machined medical implants:

• Hip implants
• Spine implants
• Knee implants

Machined surgical instruments:

• Blade handles
• Cutters
• Saws
• Forceps
• Clamps
• Spacers
• Surgical scissors
• Biopsy tubes
• Implant holders
• Plate benders

Machined parts of electronic medical equipment:

• Parts for heart rate monitors, magnetic resonance imaging (MRI) scanners, X-ray machines, ultrasound equipment, computed tomography (CT) scanners, diagnostic equipment, monitors, lighting
• Switches
• Buttons
• Levers

Micromachining:

• Stents
• Catheters
• Pacemaker components
• Drug delivery systems
• Ophthalmic devices
• Implantable devices
• Exploratory surgical tools
• Screws
• Tubes

About Stone Medical

Stone Medical was founded in 2019 by Shawn Gaskin. Founder and owner of Swiss Technologies since 2001, his increased interest in the complexity of medical device manufacturing drove him to create Stone Medical, a 5,000ft² facility.

With a solid foundation provided by Swiss Technologies, which started more than 21 years ago as a traditional Swiss CNC machine shop, we started manufacturing more intricate parts less than 1.25in in diameter, some are used in medical instruments and devices.

Shawn’s desire to expand into the medical device sector of manufacturing lead to Stone’s existence. His valuable insight, ambition to challenge his abilities and furthering his machining capabilities led to Stone Medical.
