MC-70CNC – With Uncompromising Stability, Your Precision Won’t Change 1 Year Later Best accuracy challenge Any machine working to high repeat accuracy after months and years will face several challenges. Moving part frictions, thermal expansion, temperature fluctuation, vibration, and multitude of issues that diminish the original accuracy. These were all encountered by MC-70CNC hydraulic pipe bender after operating 1 year later and remarkably maintain. This stability has not come from chance.
A Foundation of Rigidity and Mass
Rigidity and mass are actually the secret. The MC-70 CNC’s rigid and stable foundation comes from precision steel frame with ample wall thickness and reinforcement. The increased overall weight effectively reduces friction from hydraulic and mechanical components, as well as vibration. At the same time, high-strength parts resist the deformation from both external and internally produced heat which results in better and higher mechanical strength after few years. Wear resistant slideways can cause accuracy loss over time, problem Baorui addressed at the design stage.
Precision Ground Guideways and Wear Surfaces
The MC-70CNC is equipped with precisely ground and hardened slideways to prevent metal abrasion caused by vibration. Because of the good lubricity of Baorui's products and proper design of the slideways, effectively reduce metal friction and guarantee accuracy after years of use. Heat generation is actually key factor affecting machine accuracy. The stable structural design has also incorporated thermal management into its design.
Hydraulic oil cooling and temperature control systems ensure that oil is always in proper range, thus avoiding excessive fluctuation, and reducing deformation. In addition, both parts of bending are symmetrical design, thus effectively mitigating overall Deformation. Reasonable production tolerance new MC-70 CNC undergoes high-precision grinding, stress relieving, and assembly through laser accuracy measurement.
Thermal Management Through Smart Design
Temperature change is one of the biggest culprits responsible for losing precision in manufacturing environments. As parts on any machine warm up during use, they expand, although at different rate depending on the component’s material. This leads to inaccuracies and fluctuations in bend angles. The stable frame of MC-70CNC actually features design elements that address thermal issues to keep temperature variations under control. For instance, hydraulic oil cooling system prevents changes in viscosity that would lead to variations in oil pressure as well as the rate of motion control. Another point frequently missed in this type of design; both the primary bending arm and plug support have been designed to the same geometry (in terms of cross-section area) and balanced thermal pathways, thereby having matched thermal expansion and contraction with changes in temperature. This system ensures that the clamping die, pressure die and bending die always remain in the same relative position not just during an entire production day, but over matter of weeks or months as well.
Robust Manufacturing and Assembly Tolerances
To get long term accuracy in your MC-70CNC we do work long before the machine actually gets to you. Many of the major components on each MC-70CNC frame machine are treated to process called post weld stress relief. This removes all stresses that are built into the material through welding, preventing microscopic movement from occurring 10 years down the road. It also heat treats the metal’s grain structure preventing even tiny shifts and warping from taking place throughout the life of an MC-70CNC. Finally, the technicians that assemble your machine to ship you install the base components with your finest surface plates in tandem with lasers to get all three of your travel axis perpendicular and parallel to one another.
This ultra high precision will make sure that the Geometric Error of the MC-70CNC in real delivered machine will be less than zero. Plus, with its inherent rigidity, the error will never be built up in the first year of operation. For many years, Baorui machine reliability and dependability have actually formed the backbone of our business. And that business will materialize on every new MC-70CNC you purchase from us in the following ways:
• Heavy-duty framework
• Precision-manufactured guideway
• SMART thermal control
• Meticulous craftsmanship
This quality standard actually means we maintain exceptional bending accuracy from the first day you put it in service until your first year ends (and well into your shop's future). That standard makes your fabricator more productive by producing lower scrap and rework rates. In fact, it is the reason that metal fabricators in areas where such workpieces are the norm-automotive componentry, for example, medical instrumentation, and custom furnishings-all turn to Baorui for reliable pipe bending machinery.
