Great Needle Penetration Force

Powerful 550W motor outputs large amounts of torque even at slow speeds so that strong needle penetration force can be obtained. This allows accurate sewing of heavy materials and joints. If the needle penetration resistance increases, such as when sewing heavy materials and materials with joints, vibration control (intermittent impact) automatically increases the penetration force.(Patent pending)

Easy Thread Trimming Timing Adjustment (T-8422C/8452C/8722C/8752C)

Adjustment of the thread trimming timing is done simply by adjusting the position of the thread trimming cam relative to the lower shaft. There is no need to remove the timing belt and the timing between the needle and the rotary hook does not change, so there is no need for troublesome re-adjustment when the thread trimming timing is adjusted. Adjustment is easy even if the material or thread thickness changes, so that accurate thread trimming can be obtained.

Low Noise and Low Vibration for Stress-Free Operation (T-8421C/8422C/8452C/87722C/8752C)

Using a highly-rigid frame and computer analysis that achieves balance between the main parts , its noise and vibration are minimized. In particular, the high-frequency noise from the rotary hook opener that is irritating to the ears has been greatly reduced. This reduces operator discomfort and alleviates stress.

Further Improved Ease of Operation

According to the operator's preference (G50 panel)

The curve of the acceleration at sewing start can be selected on the operation panel. The machine provides more options for customizing operations by the operator's preference.
