Metalworking machines
The metalworking machines category features equipment for cutting keyways — one of the most common operations in repair and mechanical engineering. These are solutions from the Ukrainian manufacturer TechnoMashStroy for workshops, repair shops, agricultural enterprises and small production sites that need to machine bores in pulleys, gears, sprockets and hubs quickly and accurately.
The category offers a keyway broaching set based on the SPG-12 model: the machine itself and interchangeable tooling for it. You can buy a ready-to-use machine or complete your existing equipment with the missing parts.
The core of the set is a keyway broaching machine on a mobile frame with caster wheels and lower shelves, so it is easy to move around the shop and keep the necessary tooling close at hand. The guide mandrel holds the broach in the workpiece bore and sets its direction during operation, while the broaching wedge helps adjust the tool position and the keyway depth. Together, these elements cover the full machining cycle without third-party solutions.
Why choose keyway broaching
Broaching is done in a single working stroke, so the keyway comes out straight, with clean walls and consistent dimensions from part to part. Compared with slotting or milling, this method is faster and better suited to serial and repeat jobs.
- accurate keyway geometry for a standard key;
- high productivity when machining batches of parts;
- clean surface finish without additional rework;
- convenient for repairs when a keyway in a worn bore needs to be restored.
Where the equipment is used
- repair and manufacture of pulleys, gears and sprockets;
- maintenance of agricultural and industrial machinery;
- machine shops and turning departments;
- production of gearboxes, shafts and drive assemblies.
The mobile design of the SPG-12 machine lets you place it wherever it is most convenient for the job. It is a sound choice for businesses that want to perform these operations in-house instead of outsourcing them, saving time on equipment repairs.
Practical operating tips
For consistent results, clamp the workpiece securely and make sure the bore is clean and matches the size of the mandrel. Lubricate the tool in good time and replace worn tooling elements promptly. This approach extends the service life of the equipment and keeps the keyway accurate even under heavy use.
How to choose a machine and tooling
Before buying, determine the bore diameters and keyway sizes you machine most often, as well as the approximate workload. For regular use, it makes sense to buy the machine together with the mandrel and wedge right away. If you already own an SPG-12 machine, you only need to order the individual tooling elements. To avoid mistakes in choosing the configuration, clarify the details with our managers — they will tell you what suits your workpieces best.
