CNC Machining Steel Precision Turning Part Machining Services Spare Parts

CNC Machining Steel Precision Turning Part Machining Services Spare Parts


CNC machining, an abbreviation for Computer Numerical Control machining, operates as a

subtractive manufacturing technology, autonomously removing material from raw stock guided

by computer-generated instructions.


Generally, CNC machines can be classified into two types: those that keep the raw stock stationary

while rotating the cutting tool, and those that rotate the raw stock while moving it against a

stationary tool.


Various modifications and combinations of these fundamental approaches are employed, allowing

some machines to integrate both techniques for the production of intricate parts with complex

features.


Product Details


CNC turning is a versatile machining process that can effectively work with various materials.

These materials include metals like aluminum, steel, brass, and titanium, as well as plastics

such as acrylic, nylon, and polycarbonate.

Typical Applications of CNC Turning


CNC machining, as a versatile subtractive manufacturing method, plays a vital role across diverse

industries. Here are some key sectors where CNC machining is heavily utilized:


1. Aerospace: The aerospace industry relies on CNC machining to produce intricate and

high-precision components for aircraft and spacecraft, ensuring optimal performance and safety.


2. Automotive: CNC machining is integral to the automotive sector for crafting precise components,

contributing to the efficiency and reliability of vehicles.


3. Aviation: Similar to aerospace, the aviation industry benefits from CNC machining's precision

in manufacturing components that meet stringent safety and performance standards for aircraft.


4. Transportation: The broader transportation industry, including rail and maritime sectors, employs

CNC machining to fabricate robust and precise components that withstand challenging operational

conditions.
These industries showcase the widespread adoption of CNC machining, highlighting its indispensable

role in manufacturing processes where accuracy, consistency, and intricate detailing are essential.

FAQ's


1. How much do CNC machining materials cost?


CNC machining offers a plethora of material choices, leading to varying costs across different options.

The price range for materials is broad, influenced by factors such as physical properties and specific

characteristics of each material. For metal parts, Aluminum 6061 stands out as the most economical

choice.


If cost is a primary consideration, ABS emerges as the most budget-friendly option.

Additionally, the ease of machining significantly impacts costs, with materials like stainless steel

posing a higher machining difficulty compared to aluminum, thereby contributing to an increased

overall cost.


2. What's the general surface texture of CNC milled and turned parts?


Typically, machined milled parts exhibit a surface roughness of around 3.2μm (or 1.6μm for newer

machines). On the other hand, turned parts can achieve a finer surface with a roughness of 0.8μm.


This indicates that the machining speed does not necessarily need adjustment, highlighting the

precision attainable in turning processes.


3. What are your tolerances for machined parts?


For machined parts, our tolerances typically adhere to +.005”/- .005” local tolerances across most

metal geometries and +/- 0.010" for plastics. It's important to note that these tolerances may vary

for large parts, especially concerning flatness after heat treatment.


For an "As Milled" finish, a minimum surface finish of 125 is maintained for CNC parts.

Fabricated parts come with a 0.010” dimensional tolerance and a 1° angular tolerance.

Tapped holes not explicitly designated as features in the CAD model may be machined to the

diameters specified.


Additionally, no surface treatments, such as anodizing, bead blasting, iriditing, powder coating, etc.,

will be applied unless expressly paid for and acknowledged.
