Hardened Way Machine Slides
Milwaukee MachineTool manufactures HHW and LHW Series hardened-way machine slides for machining and positioning applications that require rigid support, controlled travel and vibration resistance under heavy loads. Cast-iron construction combined with hardened, precision-ground ways provides a durable slide foundation for machine tools, production equipment and automation systems.
Available in high- and low-profile configurations, HHW and LHW Series slides help engineers balance slide height, load requirements, travel range and drive style within the available machine envelope. Our engineers can help compare models, review application requirements and determine whether a standard or modified configuration is the right fit. Talk with an MMT engineer or send us your drawings.
High Profile Hardened Way (HHW) Slide Series
The High Profile Hardened Way Slide Series is built for applications requiring additional slide height, stiffness and support for heavy-mounted components. HHW slides are a strong fit for machining systems, spindle feed units and production equipment where rigidity is a primary selection factor.
High Profile Hardened Way Slide Features
HHW slides feature steel flame hardened, precision-ground ways designed to be rigid and accurate under heavy loads and vibrations. The high-profile design features deep cavity, stress relieved cast iron bases.
