With increased projection length, the cutting speed should be lowered due to possible chatter, as shown on the diagram right.Refer this diagram and tables on previous pages to determine the best cutting parameters.For cast iron, up to 20% longer projection length is generally permissible.

The relationship between nose radius of insert and max. bore depth are strongly affected to each other. Refer to the graphs shown below for proper selection of insert radius based on the CK shank size and bore depth.For cast iron, bore depth can be increased by approx. 1.1 to 1.3 times.Refer to the tables on the previous pages for cutting data.In the case of long reach applications, cutting speed should be lowered. Refer to the diagram shown above.

Using the same head and CK shank, assembly and disassembly always locates the cutting edge to the same position within the tolerance of only 2 m. Repeating this procedure many times with the same results proving boring accuracy is high and stable.

Flexible build-up system allows for longer overhang by Extension and smaller diameter by Reduction. It is further helpful to arrange and minimize the interference while retaining its rigidity. Including chamfering tools, adjustable for any bore depth position, the optimum tool layout for every workpiece is easily assembled.

Accurate repeatability of 2 m or less Diameter presetting is possible by

boring head alone.Due to the high accuracy of the CK Connection design, presetting job can be done with only the boring head. It is not necessary to carry a heavy tool and you can reduce your operation and set-up time. Also, you can prepare for many boring heads set to different jobs in advance for total operation efficiency. We recommend our CK Presetter for this.

CK Connection System

Repeatability Within 2 m

Free to assemble for required cutting depth and diameter

Only one piece of a special Set Screw with a unique steep taper works to pull the boring head in an axial direction resulting in strong face contact.

Boring operations requiring large stock allowances are made possible by the CKB Pin, designed to provide high torque transmission.

It is possible to precisely adjust both cutting edges to the same height, eliminating variation within tolerance of inserts, optimising the best condition for balanced cutting.

RW Head is designed for adjustment to both radial and axial directions. Cartridges are standard for through-hole and blind-hole boring, thus universal for various requirements.

For the Cartridge models TW98126 & TW125153, the range of boring diameter varies depending on boring head model even the same model of Cartridge is used.6. Cartridge models with "EL" cannot be used with #30 taper shank holder.

Leading and trailing inserts are arranged at different heights and diameters for the highest cuttingcapacity and a large stock allowance. Height difference is designed ideally for each model of head.Increased chip thickness aids chip control.

Model numbers of the Cartridge for step cut represent adjustable diameter range. However, since leading and trailing inserts cut in different depths, min. diameters represented in the model numbers may not be achieved.

Back boring from the same direction greatly improves the concentricity.Simply reversing a standard Insert Holder readies the tool for back boring, retaining all the same features such as simple and accurate diameter adjustment.

Whenever there is a problem with chip evacuation, it is possible to change the combination of head and Insert Holder in order to increase the clearance for chips. Each head accepts 3 different Insert Holders.

Reliable scale graduations, simple operation by only one allen key, and easy to read divisions as opposed to operating by

spanner, all this can be done while on the machines, very simple and accurate to micron unit.

Overhang length is freely adjustable

Combination with carbide cylindrical toolholder for reliable deep hole boringCarbide is three times more rigid than steel against bending. Thus using a carbide shank tool provides more accurate and stable boring.

This overhang length can be adjusted by up to 60mm (EWN2-50CK6). Therefore, the most stable conditions can be achieved for delicate and deep boring.

3 sizes are available in the series to do the best job from selection.

Best fitting to jig boring operation where extremely high accuracy is requiredIn case of jig boring operations, one boring head is required to be engaged in both semi-finishing and finishing operations. Thus, hand operation on Adjusting Ring (with ultra accurate bevel gears) alone permits micron units of adjustment on the head. Fine adjustment of the cutting edge is made by the combination of ultra accurate adjusting screw and ultra accurate bevel gears, assuring bore tolerances of H6 or H5.
