Keyway Machining

We specialize in custom keyway cutting and machining for shafts, pulleys, gears, couplings, and other mechanical power transmission components. Our keyway cutting services cover all standard and custom key sizes and configurations.

Keyways are critical for transmitting torque between shafts and mounted components. We ensure every keyway is machined to exact specifications with proper fit, alignment, and concentricity.

Our Keyway Services Include:

• Shaft Keyway Cutting: Keyways cut on shafts using milling, slotting, and broaching methods for parallel keys, Woodruff keys, and custom key profiles.
• Hub/Internal Keyway Broaching: Internal keyway cutting in pulleys, gears, couplings, and hubs using broaching tools and arbor presses.
• Slot Milling: Precision slot milling using vertical and horizontal milling machines for keyways, splines, and special profiles.
• Woodruff Key Seats: Semicircular key seat cutting using Woodruff cutters for standard and custom Woodruff key sizes.
• Custom Key Sizing: We can machine keyways for both standard metric keys (DIN 6885) and inch keys (ANSI B17.1) as well as fully custom dimensions.
• Double Keyways: Opposed and offset double keyways for high-torque applications requiring two keys.
• Keyway Gauging: Precision measurement of keyway width, depth, and position using gauges and measuring instruments.
