AI Description
BetaCapabilities
The Martin D70 is a versatile lead and feed screw lathe designed for precision metalworking. With a 710mm swing diameter over the bed and 1000mm distance between centers, it handles mid-sized components effectively. The spindle bore of 71mm accommodates various workpieces, while the 12-speed range (18–800 rpm) and 7.5kW motor provide flexibility for different materials and operations—from threading and boring to facing and turning.
Industries & Uses
This lathe suits small to medium-sized job shops, contract manufacturers, and businesses producing custom metal parts. It's commonly used in automotive suppliers, tool makers, and general engineering work where precision and repeatability matter. The digital readout system improves accuracy and reduces setup time compared to manual machines.
What to Check When Buying
When inspecting a used lathe of this age, focus on spindle runout and bearing condition—any excessive play affects precision. Check the lead screw and feed mechanism for wear or backlash, as these directly impact threading quality. Verify coolant system functionality and inspect the bed for cracks or wear patterns. Request maintenance records and ask about any recent repairs. Test operation across the speed range and inspect the tool post alignment. Given the 1968 build date, understanding the repair history is essential to budgeting for potential refurbishment.
