Machines
Engine Lathe
Engine lathe listings from Crown Mines often cover chuck size, between-centres capacity, gearbox arrangement, and the state of the bed near the headstock. Johannesburg workshops usually ask about three-phase supply, thread cutting ranges, and whether steadies, toolposts, or faceplates are with the machine.
Toolroom Lathe
Toolroom lathes suit smaller precision work such as bushes, pins, shafts, and repair components made in maintenance shops around Johannesburg. When one comes through Crown Mines, attention usually goes to spindle noise, carriage feel, collet equipment, and the condition of cross-slide screws and dials.
Boring Mill
A boring mill is generally checked for table travel, spindle movement, backlash, and how the machine was wired on its previous site. For heavier work in mining, fabrication, and pump repair, buyers around Crown Mines often look at access for rigging, base condition, and available boring bars or facing heads.
Valve Grinder
Valve grinders are commonly used for cylinder head work where seat finish, stem condition, and repeatable set-up matter more than appearance. In Crown Mines enquiries, machine owners usually ask about wheel guards, coolant arrangement, spindle smoothness, and whether the dresser and pilots are included.
Milling Used
Used milling machines move into repair shops, toolrooms, and general engineering sites that need slots, keyways, facing, and small batch work. Before a machine leaves Crown Mines, buyers normally look at table wear, feed operation, spindle taper, lubrication points, and the condition of the vice or arbour support.
Surface Grinder
Surface grinders are usually considered for finish work on plates, dies, parallels, and other parts that need a controlled flat result. Around Johannesburg, common checks include magnetic chuck hold, saddle travel, wheelhead movement, dust around electrics, and whether balancing equipment comes with the machine.
