Comma face grooving cutters (also known as comma grooving cutters or face comma cutters) are specialized tools in CNC machining for processing annular face grooves and special-shaped face grooves. They are named for their cutting edge cross-section resembling a “comma (,)” shape, and are primarily used to address working conditions that ordinary grooving cutters cannot handle, such as asymmetric face grooves and narrow-deep face grooves. Below is a detailed description from the perspectives of structure, parameters, and applications:
Cutting edge morphology: The cutting edge consists of a straight segment (main cutting edge) and an arc segment (transitional cutting edge), forming an overall comma profile — the straight segment is responsible for groove bottom/groove wall cutting, while the arc segment adapts to groove mouth transitions or special-shaped groove profiles. The cutting edge is sharp with no corner blind spots, capable of machining narrow grooves with a minimum width of 0.5mm.
Cutter body structure: Adopts an integral cemented carbide (WC-Co) or brazed insert structure (the insert material is cemented carbide/PCD, and the cutter bar is alloy steel). The cutter bar is designed as a straight bar or a 90° bent bar to meet the clearance requirements during face machining. Some models are equipped with internal cooling holes (chip removal via high-pressure coolant).
Positioning accuracy: The insert and cutter bar use a high-precision positioning groove (positioning accuracy ±0.005mm), with radial runout ≤0.01mm after clamping, ensuring dimensional consistency of face grooves.
Typical Machining Objects:Annular grooves and seal grooves on the end face of hydraulic valve blocks;Positioning grooves and special-shaped mounting grooves on the end face of motor end covers;Oil grooves and labyrinth grooves on the end face of bearing blocks;Narrow-deep special-shaped grooves on the end face of aerospace components (e.g., end face grooves of engine casings).
Process Advantages:Solves the problem of “end face machining interference” with ordinary grooving cutters (the bent design allows close proximity to the workpiece end face);Asymmetric groove profiles are formed in one pass (no multiple passes required), increasing machining efficiency by over 30% compared to ordinary grooving cutters;No risk of cutting edge chipping, and the machined surface roughness can reach Ra0.4μm, meeting the precision requirements of precision end face grooves.
Cemented carbide insert is a common core tool component in metal cutting processing. It is made of different grades of cemented carbide and has the characteristics of high hardness, high wear resistance and high temperature resistance. Suitable for various cutting processes such as turning, milling, drilling and planing, it can process various workpieces such as steel, cast iron, non-ferrous metals and composite materials. Different shapes, sizes and cutting edge forms can be customized according to processing requirements.
Star-shaped Grooving Cutters (also referred to as Penta Grooving Tools) are cost-effective indexable tools for CNC grooving and parting operations. They are named for their pentagram-shaped insert structure with 5 cutting edges, and are primarily suitable for machining shallow grooves, wide grooves, parting cuts, and shoulder grooves—especially ideal for small part and batch production scenarios.
HMS25 HMS35 HMS50 Deep Hole Honing Machine is specially used for finishing the inner hole surface of various hydraulic cylinders, cylinders and other cylindrical parts. After machining, the aperture accuracy of the parts reaches above it7, and the surface roughness reaches ra0.2-0.4 μ m。 The machine tool can also carry out local honing to correct the taper and ovality of parts.
The term “Carbide Water Tap” does not typically refer to a standard household faucet. Instead, it describes a specialized tungsten carbide valve component or a wear-resistant tap used to control the flow of water, slurry, or other abrasive fluids in industrial settings. The “carbide” designation indicates that the critical wear-prone parts of this valve are made from or protected by tungsten carbide to ensure extreme durability.
Wear-Resistant Alloys are a class of materials specifically engineered to withstand surface degradation and material loss caused by mechanical wear. This wear can result from abrasion (scraping), erosion (impact by particles), adhesion (galling and seizing), and impact. Their primary function is to extend the service life of industrial equipment, reduce downtime, and improve operational efficiency in demanding environments.
The cemented carbide wear-resistant block for the geology and mining field is a block-shaped cemented carbide component designed for high-wear scenarios in geological and mining operations. It boasts extremely high hardness, wear resistance and impact toughness. It can be directly installed on the wear contact surfaces of mining equipment (such as crusher liners, excavator bucket teeth, scraper conveyor guides, etc.), which can significantly reduce equipment wear, improve operating efficiency, and adapt to harsh working conditions such as rock crushing and ore transportation.
DIAMETERS FROM .0393” (1.0 MM) TO .4375” (11.1 MM) LENGTHS OF CUT FROM 5” (127 MM) – 14.17” (360MM)
Cemented carbide ball is a spherical cemented carbide product made by high-precision forming and sintering processes. It has extremely high hardness, wear resistance, corrosion resistance and dimensional accuracy. Widely used in bearings, valves, precision instruments, abrasive media and other fields, it can be used as rolling elements, seals, grinding media, etc., with the characteristics of long service life and stable operation.

This machine tool is a specialized machine tool for machining cylindrical deep-hole parts, suitable for drilling and boring of cylindrical deep-hole workpieces. During drilling, an internal chip removal method (BTA method) is used, i.e., oil is supplied by an oil feeder, and the cutting chips are discharged from inside the drill rod to the chip hopper at the rear of the machine head through the cutting zone. During boring, oil is supplied from the tail end of the boring bar, and the chips are discharged to the chip hopper at the head of the machine head through the cutting zone.
