CNC Dekton Tool Set For Internal Sink Cut Outs

Internal Polishing for Dekton Bowl Cut-outs: Achieve a 5mm Radii for Modern Sinks

Follow these guidelines to achieve great results on tight sink edges with specialist tools designed specifically for Dekton. The parameters included are for Dekton material. 

All tools featured are manufactured by Marmoelettromeccanica (MEM).

Products Used In This How To Guide

Step 1: Initial Core Hole

Tool: CNC Core Drill Continuous Rim SHS

To create the initial cut into the material, we recommend making a hole all the way through the material using a CNC Core Drill Continuous Rim SHS. The 1mm crown of these drills will ensure that the least amount of pressure possible will be applied to the Dekton material. This type of sintered diamond is very fine to ensure clean results. Any diameter can be used for this part of the operation, but a 35mm diameter is a usual size as this is large enough for a router to enter the material and the tool can also be used for cutting tap holes.

Technical Parmeters for Dekton: CNC Core Drill Continuous Rim SHS

• RPM Speed: 3,000rpm
• Advance Speed: 50mm/min max

Step 2: Routing The Internal Area

Tool: Straight Router Dekton MEM

Now that a core hole has been drilled through the material, a diamond router can be used to cut the area required. The Dekton Straight Router used for this part of the process is fast cutting and durable to resist the hard properties of Dekton. Make the cut with a gap of around 1.2mm greater than the final edge detail as this stock will be removed with the grinding and polishing tools. Reduce the feed rate speed to 150mm /min in order to avoid damages to the corner areas of the Dekton slab. A clockwise direction should be used when using this router.

Technical Parameters for Dekton: Straight Router Dekton MEM

• RPM Speed: 5,000rpm
• Feed Rate: 200mm/min (reduce this by 30-40% for the first three meters of material)

Step 3: Polishing The Internal Edges

Tool: CNC Profile Wheel Z30 Line 10

The 6 profile tools need to be fitted into 1/2" GAS cones and placed in the machines' magazine. The technical parameters to programme the machine are listed below. In order to remove all lines and striping, run the Pos 5 with a floating movement, if your machine has this ability. Make a double pass with the Pos 6 tool as this will help achieve the highest polish finish. The straight edges of the internal sink can be worked much faster than the corner edges; the feed rate for approaching the corners and the corner details themselves needs to be reduced to 50mm/min.

Please note that oscillation must be switched off for: Pos 4 - 6
