Industrial manufacturing tends to live in the shadow of sexier sectors. Aerospace gets the headlines, medical devices get the regulatory scrutiny, defense gets the budget attention. But the industrial sector automation, robotics, fluid power, material handling, advanced packaging, semiconductor capital equipment, and precision instrumentation quietly consumes billions of dollars of precision machined components every year.
And for good reason. Modern industrial equipment is not the rough-and-ready machinery of a century ago. A semiconductor lithography system positions components to nanometer accuracy. A robotic welding cell repeats its path to within fractions of a millimeter thousands of times per shift. A high-speed packaging machine runs at 1,200 cycles per minute, and every component that moves within it must be dimensionally consistent or the system fails. These applications demand the same precision engineering as aerospace programs; they simply do not always get credit for it.
Kremin Inc. serves industrial customers with the same capabilities, the same certifications, and the same commitment to quality that we bring to aerospace and medical programs. This post explains what that looks like in practice.
The Industrial Part Spectrum: From High-Volume Swiss to One-Off Milled Components
Industrial applications span a wider range of part types than any other sector we serve. On one end of the spectrum are high-volume, tight-tolerance components produced in quantities of tens or hundreds of thousands per year, shaft components for electric motors, valve spools for pneumatic and hydraulic systems, instrumentation fittings, and precision fasteners. On the other end are low-volume, complex components for capital equipment and automation systems, custom actuator housings, precision bores for bearing fits, and machined-to-print structural components with complex feature patterns.
Swiss turning is the right process for the high-volume, small-diameter end of this spectrum. Our eleven Swiss CNC lathes can produce shaft components, pins, spindles, and valve spools to tight cylindricity and surface finish specifications with the throughput that industrial programs require. The ability to perform turning, milling, threading, and cross-drilling in a single setup with sub-spindle backworking means we can produce complete components efficiently without the quality risk that comes from multiple setups on multiple machines.
For larger, more complex components, our CNC milling and turning centers handle the job. Multi-axis machining allows us to produce housings, brackets, and manifold components with complex feature relationships in controlled setups that deliver the dimensional consistency industrial OEMs require.
Automation and Robotics: The New Frontier for Precision Machining
The rapid growth of industrial automation and robotics has created a significant new market for precision machined components. Robot joint components require matched precision bore and shaft dimensions to achieve the backlash specifications that determine positioning accuracy. End-of-arm tooling components must be dimensionally consistent to ensure repeatable gripping and placement. Linear motion systems, ball screw assemblies, linear guides, and precision rails depend on machined housings and end blocks that maintain the geometric relationships the system was designed around.
At Kremin, we have experience with the specific requirements of automation components: tight bore tolerances to IT6 and IT5 fits, surface finish requirements that affect both function and lubrication retention, and thread specifications that must be consistent across large production batches. We also understand the material requirements of this sector: 6061 and 7075 aluminum for lightweight structural components, case-hardened steel for wear surfaces, and specialty engineering plastics for components where weight, chemical resistance, or electrical isolation are factors.
As industrial automation continues to expand driven by labor availability pressures, quality improvement goals, and the reshoring of manufacturing activity the demand for precision machined automation components will only grow. Kremin is positioned to be a long-term supply chain partner for companies building the next generation of industrial automation systems.
Fluid Power and Valve Components: Where Dimensional Accuracy Controls System Performance
Hydraulic and pneumatic systems are essentially precision dimensional problems. The clearance between a spool and its bore determines leakage and response time. The geometry of a valve seat determines sealing force and cycling life. The straightness and surface finish of a cylinder bore determines piston seal friction and efficiency. In fluid power applications, machining accuracy is not a quality metric, it is a performance specification.
We produce a wide range of fluid power components at Kremin, including hydraulic valve spools and bodies, pneumatic cylinder end caps and ports, manifold blocks with complex internal passages, and instrumentation fittings for pressure and flow measurement. These parts require the combination of Swiss turning capability (for the precise spool and shaft components), CNC turning (for cylindrical housings and bodies), and CNC milling (for manifold and block features on multiple faces) that our integrated facility provides.
Material selection for fluid power components requires attention to compatibility with the working fluid, the pressure and temperature range of the application, and the wear characteristics of sliding surfaces. We are experienced with the standard range of hydraulic and pneumatic component materials, and our quality system ensures that material certifications accompany every production order.
Semiconductor and Precision Instrumentation: Cleanroom-Compatible Machining
The semiconductor capital equipment and precision instrumentation sectors represent some of the most technically demanding industrial applications for precision machining. Components for wafer handling, lithography, deposition, and etch equipment must meet dimensional specifications measured in microns, be produced from materials that meet outgassing and contamination requirements, and arrive clean and properly packaged to avoid introduction of particles into cleanroom environments.
Kremin’s approach to these applications begins with process selection ensuring that our machining processes, coolants, and handling procedures are compatible with the cleanliness requirements of the application. We use ultrasonic cleaning systems for post-machining parts cleaning, and we package components in sealed poly bags with desiccant for applications where surface contamination is a concern. Our quality team can work with customers to develop cleaning and packaging specifications that meet their facility and process requirements.
The materials commonly used in semiconductor equipment 6061-T6 and 7075-T6 aluminum, 304 and 316 stainless steel, titanium, and a range of engineering ceramics and plastics are all part of our standard material capability. Tight anodize-allowance tolerances on aluminum components, precise thread quality for stainless hardware, and careful surface finish control for sealing surfaces are all routine requirements that our processes are set up to meet.
ISO 9001:2015 Certification: The Quality Foundation for Industrial Programs
While industrial customers may not always require AS9100D or ISO 13485, the foundation of a solid quality management system is just as important in industrial applications as in aerospace or medical. Component failures in industrial equipment cause downtime, warranty costs, and customer dissatisfaction costs that are directly traceable back to the quality consistency of the supply chain.
Kremin’s ISO 9001:2015 certification provides industrial customers with confidence that our quality management system has been independently audited and verified. Our production documentation, in-process inspection, final inspection, and nonconformance management processes apply to every job that flows through our facility, regardless of whether it carries an aerospace or medical destination. The rigor that we developed for flight-critical and life-critical applications makes us a better supplier for every other application as well.
Whether you are sourcing components for an automation system, a fluid power application, precision instrumentation, or any other industrial application that demands consistent quality and reliable delivery, Kremin Inc. has the capabilities and the certifications to be a long-term partner.
