Iskar engineers have developed a range of unique high-precision, high-precision tools for broaching of small batches of workpieces. Broaching is a precision machining method for a wide range of industrial parts. The most common applications for broaching It is the processing of keyways and splines. Isca engineers have developed a series of unique high-precision and high-precision tools for broaching of small batches of workpieces.
Concave keyway
When used with a dedicated broaching machine, the broaching tool must be designed to meet long-term production needs. The Isa BROACH series of tools can complete the entire part in one shot, shortening the machining cycle and providing a small batch of parts for keyway machining. High quality solutions. Keyway processing is becoming more and more common in general engineering and applications such as automotive, heavy machinery, gear, military and other industries.
Iskar's broaching tools can be used for blind holes or through-hole machining. Traditional blind hole machining generally uses expensive EDM (EDM). When the workpiece has an undercut or a cross hole, use Iskar The broaching tool can still process the blind keyway in the CNC machining center. The design of the Iskara cutting tool is characterized by high precision and high repeatability, so it can be used to process many difficult materials in addition to the standard machining material group. Processing materials such as titanium-based alloys, nickel-based alloys and stainless steel.
2. Lathe and milling machine solutions
The demand for machining keyways on lathes and milling machines is on the rise, and Isopoly's R&D engineers have developed a range of products for high-precision broaching. Compared to typical special broaches, Iskar's broaching The product range has many advantages: The entire machining process requires only one clamping – Isca's broaching product series completes the entire part in one setup, saving delivery time; high precision – with traditional Compared with broaching machines, CNC lathes can provide higher precision; better surface finish - high stability of CNC machine tools guarantees better surface finish; small batch processing - as long as the lathe can be operated, you can get rid of the subcontracting Dependence, which is a great advantage for the production of small batches of parts; cost savings - traditional keyway groove processing requires expensive spark or wire EDM, Isca's broaching product line is such Processing provides a more economical and faster solution.
3. Broaching product series
Iskar has developed two standard broaching product lines. Standard blade or solid carbide broach are coated with IC908 PVD, suitable for processing most materials and processing conditions. Each product series contains hard Alloy cutting edge (or insert) or cutting tool holder and suitable adapter:
3.1. Iskar XNUWB product line
The XNUWB standard product range offers an indexable solution for machining part holes larger than Ø22 mm in diameter, with a width range of 5-12 mm.
3.2. Isca SCB product line
The SCB standard product range offers a solid carbide solution for small part holes up to Ø10 mm in diameter, with a width range of 5-12 mm.
4. Precision broaching
Iskar offers the following machining tips for precision broaching: Pre-machining the undercut at the bottom of the workpiece; for better chip removal, set the tool at 12 o'clock; keep it untouched when it is retracted Processing materials; coolant is strongly recommended; avoid interrupted cutting.
5. Typical cutting parameters for broaching
Typical cutting parameters: Vc = 4000 - 8000 mm/min, Ap = 0.02-0.08 mm
6. Special solutions
In addition to the standard product range, Iskar is also developing targeted solutions for different broaching applications, such as machining of toothed, square, hexagonal and other geometries.
Many industrial fields use broaching to machine high-precision parts. Typical broaching parts include gears, drive shafts, compressor blade slots, pump rotors and valve bodies, grooved cylinders, lock cylinders, etc. No matter which field, Iskar's experts can provide technical support for the entire broaching process to ensure maximum floor production.
