The machine tool industry faces an inescapable law of physics – thermal expansion and contraction. Most functional components of machine tools are made of metal, and different metals have different coefficients of thermal expansion. A temperature change of 1°C can cause a 1-meter-long cast iron component to deform by approximately 1 micron, and this deformation is non-uniform and twisting rather than homogeneous. Swiss-type lathes and turn-mill compound machine tools integrate precision components such as live tooling, spindles, ballscrews, and guideways to a high degree. Once thermal deformation occurs, the multi-axis coordination accuracy will be compromised – and this is precisely the critical threshold for high-precision manufacturing.

For this very reason, precision machine tools must be housed in a constant-temperature environment. A truly high-precision machine tool requires not only constant-temperature assembly, but also constant-temperature conditions throughout the entire process – from component machining and storage to actual use. The environment, in essence, is part of the accuracy equation.

JSWAY CNC COMPANY understands this principle deeply. In 2025, JSWAY completed a comprehensive upgrade of its main assembly workshop, transforming it into a constant-temperature space where temperature fluctuations throughout the year are strictly controlled within industrial thermal benchmarks. Here, thermal deformation is completely eliminated – critical processes such as precision bearing pressing, ballscrew and guideway alignment, and machine tool geometric accuracy integration are all carried out under a constant "thermodynamic baseline."

However, constant-temperature assembly is not simply a matter of installing a few air conditioners. JSWAY's constant-temperature workshop is also equipped with automatic air shower and shoe cover dispensers to maintain cleanliness. The fully renovated epoxy flooring is not only aesthetically pleasing but also eliminates the possibility of micro dust generation. From the selection and pairing of precision bearings and spacer measurement, to the installation of linear guide rails, every detail reflects an unwavering commitment to quality.

Operating in parallel with the constant-temperature workshop is another line of defense for precision at JSWAY – the inspection laboratory, maintained at a constant temperature of 20±1°C. Here, a coordinate measuring machine (CMM) performs rigorous 100% inspection on all core components, ensuring that every detail meets the pursuit of "precision craftsmanship."

High-precision machine tools are not casually "hammered out" in an outdoor environment. Instead, they are meticulously "cultivated" step by step within a constant-temperature and constant-humidity "precision clean room," using a fully controllable environment, first-class equipment, and an extreme attention to detail.

For Swiss-type lathes and turn-mill compound machine tools, the value of constant-temperature assembly lies in this: when precision components are fitted at a stable temperature, the fitting relationship remains consistent throughout the entire machining process. As a result, the dimensional consistency of batch-produced parts is fundamentally guaranteed. Subsequently, combined with JSWAY's self-developed thermal error compensation technology and full-axis laser interferometer inspection, accuracy is closed-loop at every level – from assembly source to final shipment – and ultimately delivered to the end user.

From constant-temperature assembly to thermal error compensation, from stress relief to laser calibration, JSWAY is defining a new paradigm for high-end manufacturing – making the environment the "home court" for precision, and making "micron-level batch consistency" the baseline for every Swiss-type lathe and turn-mill compound machine tool leaving the factory.

Under constant temperature, microns become achievable. JSWAY CNC COMPANY is reshaping the accuracy standards of China's high-end machine tools through the power of environment.
