Amelia, it depends on many factors, size, complexity, precision, and more. If you can upload your design and request a quote for detail budgeting of your project.

Thanks Choi Hye! Creating spiked washers using PEEK (Polyether ether ketone) in CNC machining involves several considerations to ensure quality and precision:

1. Tool Selection: Use sharp, carbide-tipped or diamond-coated tools for cutting PEEK. These materials offer the required hardness and heat resistance for machining this thermoplastic.

2. Cutting Parameters: Set optimal cutting speeds and feeds. PEEK can be sensitive to heat generated during machining, so a balance between speed and heat generation is crucial. Slower speeds and higher feeds are often recommended.

3. Coolant Usage: Utilize a coolant to manage heat buildup. However, ensure that the coolant is compatible with PEEK to avoid chemical reactions or material degradation.

4. Design of Spikes: Carefully design the spikes on the washers, considering the end application. The dimensions and sharpness of spikes should be tailored for the intended use while ensuring they can be reliably machined.

these are the general values, for optimum result you have to consider the factors like required Ra value, complexity, and machining conditions to optimize the feed rate, cutting speed and other parameters.

Milling: Feed rate 0.05 – 0.02 mm/ tooth, cutting speed 50- 300 m/ minute.
Turning: Feed rate 0.1 – 0.5 mm/ tooth, cutting speed 150- 500 m/ minute.
Drilling: Feed rate 0.1 – 0.3 mm/ tooth, cutting speed 50- 100 m/ minute.

Does these work in all conditions?
