[[File:M300Final.jpg|250px|thumb|Harrison M300 Metalworking Lathe]] The Harrison M300 lathe is an educational/Light-duty industrial lathe well suited for our requirements. It has a maximum part diameter of 330mm and a maximum length of 650mm and is designed to work with all standard engineering metals and well as most plastics but please note it is NOT suitable for use with any types of wood because wood fibres are sticky and abrasive so they tend to cause damage to the slideways. Induction is required for all members wanting to use the lathe and this is controlled by a card reader mounted next to the main power switch. The lathe has now also been fitted with a [[Tools/metallathe/DRO|Digital Read-Out (DRO)]] to make it easier to use, it's still settling in and isn't fully accurate yet but it's usable. The instruction manual for the lathe is available [[media:M300Manual.pdf|here]]. The instruction manual for the DRO is [[media:Lathe DRO Manual.pdf|here]], please do not change the settings.

Harrison M300 Light-industrial Metal Lathe
Owing to it's dangerous nature, delicate nature, or expense, this tool requires that you be inducted on it's proper handling before use. |
Introduction[edit]
The Harrison M300 lathe is an educational/Light-duty industrial lathe well suited for our requirements. It has a maximum part diameter of 330mm and a maximum length of 650mm and is designed to work with all standard engineering metals and well as most plastics but please note it is NOT suitable for use with any types of wood because wood fibres are sticky and abrasive so they tend to cause damage to the slideways. Induction is required for all members wanting to use the lathe and this is controlled by a card reader mounted next to the main power switch. The lathe has now also been fitted with a Digital Read-Out (DRO) to make it easier to use, it's still settling in and isn't fully accurate yet but it's usable. The instruction manual for the lathe is available here. The instruction manual for the DRO is here, please do not change the settings.
Current Status[edit]
Date | Status | Comment |
---|---|---|
23rd March 2022 | Fully Functional | Coolant line replaced |
Induction levels available[edit]
Induction options are level-1 which covers safe use of the machine and a handful of simple topics suitable for very simple jobs and is available from all trainers, takes about 60 minutes, with a maximum group size of 3 but 1-to-1 will go faster. Level 2 induction which covers a few more topics and is likely to deal with most machining operations that occasional users are likely to need. Level 2 induction takes 2 x 2hr sessions with a maximum group size of 2 although 1-on-1 sessions are available, there may be a small charge for the materials used during training. Level 3 induction which covers most machining operations that are likely to occur even on complex projects as well as some of the more complex maintenance tasks on the lathe. Level 3 induction will take multiple sessions of 3+ hours and is 1-to-1, again there will be a small charge per module for materials used and trainer time.
Some of the inductors also offer workshop sessions that involve completing a specific project rather than general lathe operations, these sessions will include at least a basic induction and usually include some but not all material from other induction levels. Charges and times for these vary, see the workshops page.
Tools currently available[edit]
The lathe is fitted with a Multifix clone quick change toolpost, size A. We have a number of toolholders available for use. If you change a tool, please re-fit the original before putting the toolholder back on the board.
Lathe users with level-1 induction should be using the High-Speed-Steel turning tools as they're cheap, robust and easily re-sharpened, for users with level-2 induction we have the following carbide-insert tooling available
Accessories[edit]
