Deburrer launched for chamfer lengths of up to 7 millimetres
The new deburrer TruTool TKA 700 from TRUMPF can create chamfer lengths of up to seven millimeters in mild steel (400 N/mm2). Only two work steps are required, says the company: the user can achieve five millimetres in the first step with the new model, while the remaining two millimetres are generated in the second step.
Different multi-edge cutters make helix angles between 15 and 60 degrees (in 5-degree increments) possible. Furthermore, the new deburrer can also be used for many applications of weld seam preparation. “Even chamfering with radii of two, three or four millimetres is possible without any problems,” adds TRUMPF.
The main decisive factor for the TKA 700's high-performance capacity is the new motor – a 1700-watt-strong, compact angular geared motor with speed control. “It provides high speeds and facilitates reliable continuous operation, even under great strain. The machine holds up even when the user is operating with high pressures and considerable feed quantities, without a negative impact on the power unit's useful life.
"TRUMPF's developers have equipped the TruTool TKA 700 with additional overload protection, which prevents the power unit from overheating for extreme cases of overstressing.”
Ergonomics are very important in the practical operation of power tools, which is why TRUMPF has ensured that the new deburrer is particularly quiet with low vibration levels, thanks to precisely manufactured gear wheels in the gear unit. The integrated soft start also facilitates a smooth start-up.
A mechanical safety clutch is said to minimise any kickback, if the machine is blocked. This can happen when a chamfer length is set that is not compatible with the material, for example. "The excellent handle position is also very helpful. This means that the user's guiding hand is very close to the machining area, ensuring high stability and precise guidance.
“With just 3.5 kilograms, the TruTool TKA 700 is a lightweight in its class, impressing with its high processing quality and ergonomics, as well as its ease of handling. The chamfer height can be set smoothly and precisely without tools, simply by turning the support plate.
A force-fit connection prevents the selected setting from being accidentally adjusted. The employed multi-edge cutters can be turned three times, are durable and easy to replace when required.”
