CNC Turning FAQs

1.Is My Part a Good Fit for CNC Turning?

The following parts are a good fit for lathe machining:

Rotary parts with high precision requirements.

Rotary parts with complex surface shapes.

Rotary parts with lateral machining.

Ultra-precision and ultra-low surface roughness parts.

Parts with special threads.

2.What Parts Can Be Made with CNC Turning?

CNC turning is used for creating a variety of parts, including auto parts, knobs, tubes, gears, toy parts, flywheels, crankshafts, hubs & disc cams. It is most often used to manufacture CNC parts online for automotive, aerospace, medical, and other industries.

3.What is CNC Turning Center - Difference Between CNC Lathes and CNC Turning Centers?

CNC turning center, the equipment or machines for CNC turning service, is a computer-controlled 3, 4, or 5-axis machine that has capabilities of turning, drilling, tapping, and milling, using live tools with powered rotary tool turret, dual spindles, Y-axis, and multiple turrets. While CNC lathe machine is simpler 2-axis with one spindle, basically composed of headstock, carriage, tailstock, and bed.

- CNC turning centers have more complex structures than CNC lathes.

- CNC turning centers have higher production capabilities and versatility than CNC lathes.

- CNC lathes are generally flat-bed type while turning center usually slant-bed type.

- There are only minimal protective enclosures around the lathe while the turning center is commonly equipped with full enclosures to keep chips and coolant splashes within the machine.

4.What is the Difference Between CNC Turning and Milling?

The most significant difference is that CNC turning rotates the part for cutting, CNC milling rotates the tool to cut the part. Going further, CNC turning will typically be used for cylindrical parts, as you rely on the part itself to rotate and create friction to remove material when the cutting tool is placed against it. On the other hand, CNC milling can create more complex parts as it is the cutting tool (rather than the material) that is spinning.

5.Heat Treatment of Precision Turned parts

Heat treatments can be applied on precision CNC turned parts to improve their key properties such as hardness. Heat treatment can be applied to metal parts throughout the manufacturing process.

- Hardening: used to harden the material and make it stronger, also decreases the ductility.

- Annealing: heats metal parts to a very high temperature and then slowly cools to achieve the desired microstructure.

- Normalizing: used to relieve internal stresses that were created during machining service.

- Quenching: heating the metal to a very high temperature, followed by a rapid cooling step.

6.How to Reduce the Cost of Machining Parts?

The main costs related to CNC machining can be divided into machining time, start-up cost, material cost, and feature cost. To reduce costs, you need to understand the impact of these factors on costs.

- The best way to reduce machining time is to design features that can be processed quickly, such as by selecting the correct inner corner radius, reducing the cavity depth, increasing the wall thickness, limiting the thread length, and designing holes of standard size.

- The material cost can be reduced by considering the size of the required blank and the cost and machinability of bulk materials (softer alloys process faster).

- Start-up costs can be reduced by reducing the number of part rotations or repositioning required to complete the part, such as dividing the geometry into multiple parts that can be assembled later.

- Using tolerances only when strictly necessary, deleting all text and letters, and avoiding multiple surface treatments can reduce feature costs.
