MK’s design concept is to combine the guide sleeve with a chip basket so that the two items can travel uniformly. The movement of the guide sleeve is driven by the air, which helps to provide closer contact during the escape of the coolant medium. For longer deep hole drilling applications, it may be necessary to stabilize the deep hole drilling tool with a supporting liner.
The precision of deep hole drilling is greatly improved by rotating the slow part of the counterclockwise direction.
For deep hole drilling applications over 18 mm in diameter, MK can choose to equip its largest processing unit from the BTA or EJEKTOR series of drilling systems. In these applications, coolant and chip management are performed through the main axis center. The emulsion is collected at the back end of the main shaft and re-entered into the cooling system after filtration and pressure. Such solutions are often used in high-precision parts manufacturing in industries such as automobiles.
In order to process stainless steel and titanium alloys, the company introduced a new type of ex-carbon – Calloy tool drill.
The Calloy tool drill is designed specifically for problems that are common in processing stainless steel and titanium alloys, such as machining hardening, elongated chips, low thermal conductivity and welding of tools.
A notable feature of the Calloy tool drill is the newly designed super cooled coolant hole. They provide improved coolant flow to improve chip evacuation and reduce heat generation. The geometry of the flute and the sharp cutting edge produce a tightly cut chip that prevents the chip’s packaging.
In addition, the Calloy tool rig provides a stable regrind and eliminates the hardening of work in the extra manufacturing process by reducing the edge wear of its distinctive edge shape and OSG’s WXL coating.
With these features, Calloy tool’s drills are reported to show twice the length of its tool life by using more than 3,100 linear inches in the case of hard-to-process dual-body stainless steel.
