Part no: 07-346-505-001

Material: High lead bronze, C93800

Machining Details: The machining center is equipped with a cutting tool for machining high lead bronze. The tool is guided by a computer-controlled numerical path for accurate and consistent cutting.

The machining process involves:Roughing: The tool initially removes excess material from the workpiece to achieve the desired shape and size.

Finishing: After roughing, the tool performs a finishing pass to smooth the surface and achieve the required precision.

Additional Features:

Coolant System: The machining center is equipped with a coolant system that sprays a lubricating and cooling fluid onto the workpiece during machining. This prevents excessive heat build-up and ensures a smooth cutting process.

Automatic Tool Changer (ATC): The machining center has an automatic tool changer that allows it to quickly switch between different cutting tools, reducing downtime and increasing efficiency.

Workholding Fixtures: The workpiece is securely held in place by specialized fixtures that maintain its position during machining.

CNC machining center capabilities:

Tolerance — ±0.01 mm on bore diameters, ±0.02 mm on face dimensions. Repeatable across production runs.

Speed — Roughing and finishing in a single setup with automatic tool changer.

Coolant system — High-pressure coolant through the spindle and external nozzles. Prevents work hardening of bronze and leaded alloys during cutting.

Horizontal CNC lathes — production equipment for crusher bushing and shaft machining. Chuck clamps the workpiece, tool post holds the cutting insert, tailstock supports the free end. Numerical control handles positioning, feed rate, and spindle speed.

Typical tolerances: ±0.01 mm on diameters, surface finish Ra 0.8–1.6 µm. Used for eccentric bushings, socket liners, shaft journals, and thrust bearing seats.
