Valve Grinder specs
Setup notes and briefing numbers for Valve Grinder.
Valve and spindle measurements
The Valve Grinder specs page gives the key measurements and setup details needed before purchase. It should cover capacity, spindle arrangement, included fixtures, electrical requirements, and the machine's overall condition.
List the valve head diameter range, stem size capacity, and the type of spindle or chuck fitted to the grinder. Buyers in Johannesburg often need to check whether a machine suits small petrol valves, larger diesel work, or mixed reconditioning jobs. Electrical supply, motor rating, and wheel size also need to be listed before moving any unit out of Crown Mines.
Condition notes matter as much as the headline capacity. Check whether the valve rotation runs true, whether the table feed is smooth, and whether guards, coolant parts, and stone dressers are present. A clear photo set should show the workhead, wheel area, control switches, and any loose fixtures supplied with the machine.
Details worth checking first
A useful specs page should identify the clamping method, spindle speeds if marked, and any accessories used for stem grinding or seat work. It should also mention if the machine is new or used, whether it has visible wear on slides or handles, and what tooling comes with it. For workshop planning, overall dimensions and machine mass help with loading and placement.
Before sending a query through the contact form, match the listed capacity to the valve sizes you actually recondition. Confirm the supply voltage in your shop, note any missing fixtures visible in the photos, and record the model number so the correct machine is referenced. If a wheel, chuck, or guard is not shown, ask whether it forms part of the sale.

Workshop checks for South Africa
In Gauteng workshops, three-phase availability and cable condition should be checked before installation of any valve grinder. Transport from Crown Mines also means confirming machine footprint, lifting points, and whether coolant tanks or cabinets are separate pieces. Used equipment should be inspected for rust, cracked wiring, and repaired switchgear before energising.
Dust from general engineering work can affect wheel guards, slides, and collet areas if covers are missing. Near the coast, surface corrosion on bare metal and electrical contacts deserves closer attention than it might inland. Where load-shedding has been a factor, ask how the machine was tested and whether the motor was run under power.

Valve grinder information to send
Send the valve type, typical stem diameters, and your power supply with the enquiry. Include any need for collets, pilots, stone holders, or cabinet-mounted coolant equipment.
It helps to keep the machine reference, visible serial plate, and required accessories in one note before purchase. When comparing used units, record wheel size, included tooling, and any play in the spindle or feed handles so the decision rests on workshop facts.
