The Challenges in Bringing Top-Grade Swiss Turning Services in Canada

When we purchased our first Swiss-style Tsugami lathe in 1991, it was virtually impossible to find quality Swiss turning services in Canada. Even though at the time many industries were already looking towards miniaturization and micro pieces, solutions on the North American continent were effectively nonexistent. Vendors who needed high-precision, small-scale, complex components had to look overseas.

Twenty-five years later, Integral Machining is the premiere shop to turn to when a business needs Swiss turning services in Canada or the USA.

However, just because we make it look easy doesn’t mean that it is easy. Every job we undertake is a new challenge, with new issues that have to be overcome to do it right. That’s what makes our work so rewarding, and that’s why so many companies turn to us for job after job.

Overcoming Challenges When Providing Swiss Turning Services

  1. Inconsistent bar diameter

When trying to cut a piece of material with a micron level of precision, even the slightest inconsistencies in the bar’s diameter can wreck the entire project. The solution is to have an adjustable guide bushing, precision ground material, or send out the raw material for centreless grinding. The part is only as precise as the most inconsistent factor in the machining process.

  1. Thermal Expansion

If you heat metal, it expands, which wrecks tolerances. Cutting processes heat the metal, and some alloys such as Grade 5 Titanium don™t dissipate that heat very well. How does one overcome this? Precision mechanisms capable of monitoring the heat of the material, which then adjust the feed and turning speed to compensate, chilled guideways and ball screws, and a controlled working environment. Also, sometimes coolants can be used. Sometimes.

  1. Coolant Reactions

Some metals react badly to chemical coolants, either producing harmful by-products or otherwise changing shape. To determine whether a coolant can be used, we stay in close contact with material vendors to discuss the properties of their products. Communication is another key to precision machining.

  1. Burrs and Melted Edges

How do you prevent burrs and improperly-melted edges when working at the micro scale? It’s about smart machining tool path strategies. Computer-controlled systems understand the topography of the metal at a microscopic level, allowing us to program tool paths which prevent edge problems.

The Right Tools for Every Job

Integral Machining Ltd. provides top Swiss turning services in Canada by investing in custom tools. We don™t use off-the-shelf tools for our micro work. Our shop is filled with custom components, some self-designed, specifically to ensure every job is done right.
