Spec Card
A straight guide to machine spec cards for South African workshops comparing lathes, boring machines, and valve grinding equipment.
How Spec Card helps buyers compare machines
Spec Card explains the machine details buyers should compare before making a decision. For Erin Machine Tools, that often means checking swing, bed length, spindle capacity, motor size, and included tooling on lathes and other workshop equipment.
Begin the spec card with the machine class and the size of work you need to handle. On a lathe, note swing over bed, distance between centres, spindle bore, motor rating, and any steadies or chucks included. Buyers in Johannesburg may also want the supply details, machine weight, and overall dimensions checked before arranging loading or placement in the workshop.
A first set of photos should support the figures on the spec card, not replace them. Include close views of the bedways, chuck, gearbox plates, tailstock, and any wear points that affect use. Keep a printed copy near the machine when inspecting so missing tooling and visible faults can be marked while you are standing there.
Key figures buyers compare
A useful spec card sets out the model details in plain terms and leaves less room for guesswork. It should show capacities, fitted accessories, electrical information, and anything that is not standard on the machine. For used equipment, add visible wear, missing parts, and whether the machine was seen under power.
Keep it with current machine photos and any notes on delivery timing or disclosed faults. Before sending an enquiry through the contact form, check that the machine name, model, and capacity figures match the tag on the unit. One image of the control side or headstock usually helps when there are similar machines in stock.
- Swing, centres, bore, motor, tooling
- Bed wear and backlash noted
- Power supply and weight confirmed
Checks that matter in SA
Workshop conditions in South Africa can change which spec points matter most. In Crown Mines and other industrial areas around Johannesburg, access for rigging, three-phase supply, and space around the machine often need checking before purchase. For equipment going inland or to the coast, rust, storage, and transport handling should be recorded with the machine details.
Power interruptions make a test run more valuable when a used machine is being assessed. Dust affects slides, lead screws, and exposed ways, so photos should show covers and general cleanliness. On older lathes and boring machines, ask whether coolant gear, pumps, and electrical panels are still fitted and serviceable.

Using the card on inspection
Use the spec card with machine photos, delivery timing, and any faults already disclosed. Keep the subject line accurate.
Take the spec card with you when viewing a lathe, boring machine, or valve grinder. Tick off the plate data first, then compare the listed tooling against what is physically with the machine. If anything differs, record it there and then so the buying file reflects the machine as inspected.
